A network adapter allows an electronic device to interface with a local computer network.

Types of Network Adapters

A network adapter is a unit of computer hardware. Several types of hardware adapters exist:

• Many new computers contain integrated (built in) wireless network adapter chips
• A USB network adapter plugs into a standard USB port to enable computer network connections (typically Wi-Fi or Ethernet)
• A wireless game adapter (sometimes called a “media adapter”) connects to an Xbox or Playstation game console or other home entertainment product, providing a bridge to Wi-Fi wireless capability.
• On older PCs,a PCI adapter (often called a NIC) was a type of add-in card installed inside a desktop personal computer. A variant PCI adapter called “PC Card” (also known as PCMCIA cards) inserted into the side of a notebook computer to provide similar capability.

Adapters are a required component to include when building a network. Every common adapter supports either Wi-Fi (wireless) or Ethernet (wired) standards. Special-purpose adapters that support very specialized network protocols also exist, but these are not found in homes or most business networks.

Determine Whether a Network Adapter Is Present

Newer computers often include a network adapter when sold. Determine whether a computer already possesses a network adapter as follows:

• In desktop computers. look for an RJ-45 jack on the back of the computer. The RJ-45 jack appears similar to a phone line jack but is slightly larger.
• In notebook computers, look for a thin, removable metal device roughly the size of credit card, but thicker.
• For notebook computers running Windows that may contain integrated adapter chips, open the Windows Device Manager. Device Manager can be accessed from the Hardware tab of the System Properties section of Windows Control Panel
• In any type of computing device, look for a small external device with LED lights connected to a USB port

Purchasing a Network Adapter

A network adapter can be purchased separately from most manufacturers that supply routers and other forms of networking equipment. When purchasing a network adapter, some prefer to choose the brand of adapter that matches their router. To accommodate this, manufacturers sometimes sell one or two network adapters together with a router in a bundle called a home network kit. Technically, however, network adapters all offer very similar functionality according to the Ethernet or Wi-Fi standard they support.

Installing a Network Adapter

Installing any network adapter hardware involves two steps:

1. Connecting the adapter hardware to the computer
2. Installing any required software associated with the adapter

For PCI adapters, first power down the computer and unplug its power cord before proceeding with the installation. A PCI adapter is a card that fits into a long, narrow slot inside the computer. The computer’s case must be opened and the card firmly inserted into this slot.

Other types of network adapter devices can be attached while a computer is running normally.

Modern computer operating systems automatically detect newly connected hardware and complete the basic software installation required.

Some network adapters, however, additionally require custom software installation. Such an adapter will often be accompanied by a CD-ROM containing the installation media. Alternatively, the necessary software can be downloaded for free from the manufacturer’s Web site.

Software installed with a network adapter includes a device driver that allows the operating system to communicate with the hardware. In addition, a software management utility may also be supplied that provides a user interface for advanced configuration and troubleshooting of the hardware.

These utilities are most commonly associated with Wi-Fi wireless network adapters.

Network adapters can normally be disabled through their software. Disabling an adapter provides a convenient alternative to installing and uninstalling it. Wireless network adapters are best disabled when not in use, for security reasons.

Virtual Network Adapters

Certain types of network adapters have no hardware component but rather consist of software only. These are often called virtual adapters in contrast to a physical adapter. Virtual adapters are commonly found in virtual private networks (VPNs). A virtual adapter may also be used with research computers or IT servers that run virtual machine technology.

Summary

The network adapter is an essential component in both wired and wireless computer networking. Adapters interface a computing device (including computers, print servers, and game consoles) to the communication network. Most network adapters are small pieces of physical hardware, although software-only virtual adapters also exist. Sometimes a network adapter must be purchased separately, but often the adapter is built into a computing device, especially newer devices. Installing a network adapter is not difficult and often is a simple “plug and play” feature of the computer operating system.

A week after it was first revealed Apple was slowing down older iPhones, ostensibly to stabilize performance, the company has succumbed to mounting pressure and, as an apparent gesture of goodwill, is offering owners of an iPhone 6 and later models a battery replacement for $29 — a limited-time $50 discount.

You are likely familiar with the rumor that Apple throttles older iPhones in an effort to make users resort to buying new devices. Of course, Apple maintains that’s not the case and it offered a statement regarding why iPhones may struggle as they get older.

Apple confirmed it slowed down older iPhones in an effort to better handle the power output that aging batteries can offer. Some users were upset. So much, in fact, that several lawsuits have been filed against the company.

“Defendant breached the implied contracts it made with Plaintiffs and Class Members by purposefully slowing down older iPhone models when new models come out and by failing to properly disclose that at the time the parties entered into an agreement,” reads a lawsuit filed by Wilshire Law Firm on behalf of Stefan Bogdanovich and Dakota Speas. The pair are seeking both California and nationwide class action status for their suit, according to a report from TMZ.

Apple Insider has reported that attorneys on behalf of Keaton Harvey have filed another suit against Apple. The class-action suit alleges that the company’s decision to slow down old iPhones “allowed Apple to conceal the true nature and scope of the battery defect and to avoid expending time, money, and effort on correcting it.”

The suit requests that Apple notify owners about changes to the OS, repair the flaws in the software that led to the throttling, and reimburse those who bought affected iPhones.

In light of the suits, on Thursday, December 28, Apple released an apology for the confusion surrounding battery and performance issues. In its apology, the company stated “we have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that.”

Apple also promised to release a software update in 2018 that will allow users to better monitor battery performance and health on their devices. Additionally, it stated it will reduce the price of battery replacement on all iPhone 6 phones and later to $29 for the next year.

Recent throttling accusations first appeared a couple of weeks ago, when a Redditor shared Geekbench results take right before and right after the battery in an iPhone 6S was replaced. According to the Redditor, who goes by the name TeckFire, the iPhone performed as much as 20 percent better after the battery replacement.

After the Reddit post, John Poole, who founded Primate Labs, offered a more visualized look at the link between battery health and iPhone performance. Benchmarking tests were performed on iOS 10.2.0 and 10.2.1, and show some pretty serious differences in performance. Apple introduced an update in iOS 10.2.1 aimed at fixing an issue where some iPhone 6S models shut down, thanks to uneven power delivery from older batteries in the phones. That power management feature is what was causing the performance dips on some iPhone models.

According to Apple, there is a good reason for the performance dip.

“Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge, or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components,” Apple said in a statement to TechCrunch.

In other words, when an iPhone’s battery gets older, it becomes less capable of delivering enough power to the processor during a peak of performance, and when that happens it has to spread out the power requests over a few processor cycles. The result of that is a dip in performance.

That’s what is triggered when benchmarks are run — they look like performance peaks and valleys to an operating system, and as such on older batteries the power requests will be spread out. Upgrade to a new battery, and power will be delivered much more effectively.

It’s not all that surprising. As a battery ages, it stops working as well. That has always been the case and likely always will be. That doesn’t mean that the average performance of a device is being affected, nor does it mean that Apple is throttling your phone to make you upgrade. OF course, Apple could have been a little more transparent — a simple notification telling users that their battery is getting old and that they may see a performance dip because of it would go a long way. That lack of notification may be a serious point of contention when and if the new lawsuit ever gains ground.

Still remember the last time the last drop of power of the original battery？ You hate the battery for it almost ruined your most important presentation to your clients. But by following certain  practices, you will change your affections towards your moving energy friend. Here’s how.

The fewer you drain it, the longer the battery last

Usually, laptop batteries are able to handle around 500 full charge cycles, which means, each charge cycle decreases a battery’s capacity from its design specifications.

Your laptops like “new mode”

You can start saving your battery by changing the power settings corner of your laptop.

It would be better, If your laptops offer the function of “eco mode” which may adjusts the way power automatically to conserve battery energy. And, shifting to the Hibernation mode once you leave for a moment is really a good habit for laptop battery life.

Less running app, more energy

To save even more power, take a tour of your apps and quit any that are running in the background and slowly eating into your battery life. No matter your computers are in Windows or macOS , you can what apps are using the most power by resetting the energy section. Both Microsoft and Apple offer you the instruction in video.

Besides, you can also reduce the amount of power by shutting off Wi-Fi or Bluetooth when you’re absent, turning off optional features such as keyboard backlighting.

Half charging for laying up

Though battery life is longer than before, it does not mean that the energy will be always waiting for you for a long time ignorance. So if you have the plan to store your laptop for an time without using it, then charging it to 50 percent before putting it away will be better.

How to Choose the Proper Display and Graphics for a Laptop

When looking at the video for a laptop there are four items to look over: screen size, resolution, screen type and graphics processor. For most people, only the screen size and resolution are all that will really matter. The graphics processor really only tends to make a difference for those looking to possibly do some mobile gaming or high-definition video but they can be used for more than that.

Pretty much all laptops use some form of backlit active matrix display to allow for bright fast displays capable of video playback.

Screen Size

Laptop screens have a wide range of sizes depending upon the type of laptop system that you are looking at. Larger screens provide an easier to view screen such as those for desktop replacements. Ultraportables tend to have smaller screens allowing for a reduced size and increased portability. Almost all systems now offer a wide aspect ratio screen either for a more cinematic display or to reduce the size of the screen in the depth dimension for an overall smaller system size.

All screens sizes are given in a diagonal measurement. This is the measurement from the lower screen corner to the opposite upper corner of the screen. This will typically be the actually visible display area. Here is a chart of the average screen sizes for different style laptops:

• Ultraportable: 13.3″ or Less
• Thin and Light: 14″ to 16″
• Desktop Replacement: 17″ to 19″
• Luggables: 20″ and Higher

Resolution

Screen resolution or native resolution is the number of pixels on the display listed in the number across the screen by the number down the screen. Laptop displays look best when the graphics are run at this native resolution.

While it is possible to run at a lower resolution, doing so creates an extrapolated display. An extrapolated display tends to cause reduced image clarity as the system has to use multiple pixels to try and display how a single pixel would normally appear.

Higher native resolutions allow for a greater detail in the image and increased work space on the display. The drawback to high resolution displays is that fonts tend to be smaller and can be more difficult to read without font scaling. This can be a particular drawback for people who have poor eyesight. It can be compensated by changing the font size in the operating system, but this may have unintended results in some programs. Windows has this problem in particular with the latest high resolution displays and desktop mode applications. Below is a chart of the various video acronyms that refer to resolutions:

• WXGA: 1366×768 or 1280×800
• SXGA: 1280×1024
• SXGA+: 1400×1050
• WXGA+: 1440×900
• WSXGA+: 1600×900 or 1680×1050
• UXGA: 1600×1200
• WUXGA: 1920×1080 or 1920×1200
• WQHD: 2560×1440
• WQXGA: 2560×1600
• WQXGA+: 2880×1800
• WQSXGA+: 3800×1800
• UHD: 3840×2160 or 4096×2160

Screen Type

While the screen size and resolution are the primary features that will be mentioned by manufacturers and retailers, the screen type can also make a huge difference in how the video performs.

By type I am referring to what technology is used for the LCD panel and the coating that is used over the screen.

There are two basic technologies that are used in LCD panels for laptops right now. They are TN and IPS. TN panels are the most common as they are the least expensive and also tend to offer faster refresh rates. They do have disadvantages including narrow viewing angles and colors. Now, the viewing angles impact how well the screen color and brightness looks the further off center you viewing the panel at. Color refers to the color gamut or total number of colors that the screen can display.

TN panels offer less overall color but this typically only matters for graphics designers. For those wanting higher color and viewing angles, IPS does both of these better but they tend to cost more and have slower refresh rates and are not as suited for gaming or fast video.

IGZO is a term that is being mentioned more often regarding flat panel displays. This is a new chemical composition for building displays that is replacing the traditional silica substrate. The primary benefits of the technology is to allow for thinner display panels with lower power consumption. This will eventually be a major benefit for portable computing especially as a way to combat the extra power consumption that comes with higher resolution displays. The problem is this technology is very expensive right now so not very common.

OLED is another technology that is starting to show up in some laptops. It has been used for high end mobile devices like smart phones for some time. The primary difference between OLED and LCD technologies is the fact that there is no backlight on them. Instead, the pixels themselves generated the light from the display. This gives them better overall contrast ratios and better color.

Touchscreens are becoming a major featuring in many Windows based laptops thanks to the new Windows interface design based around touch. It should be noted that this can easily replace the trackpad for many people as they navigate the operating system. There are a couple downsides to touchscreens through as they generally add to the cost of a laptop and also draw more power meaning that they have less running time on batteries than a non-touchscreen version.

Those laptops that do have touchscreens might come with a display that has the ability to be folded over or spun around to also provide a tablet experience. These were often referred to as convertible or hybrid laptops. Another term for them now thanks to Intel’s marketing is 2-in-1. The important thing to consider with these types of systems is the ease of use in the tablet mode as based on the screen size. Often, the smallest screens such as 11-inch work best for these designs but some companies make them up to 15-inches which are frankly difficult to hold and use.

The majority of consumer laptops tend to use glossy coatings over the LCD panels. This offers a greater level of color and brightness to come through to the viewer. The downside is that they are more difficult to use in certain light such as outdoors without producing a large amount of glare. They do look great in home environments where it is easier to control glare. Pretty much every display panel that features touchscreen uses a form of glossy coating. This is because the hardended glass coatings are better at combating fingerprints plus they are much easier to clean.

While most consumer laptops feature glossy coatings, corporate style laptops generally feature anti-glare or matte coatings. They help reduce the amount of external light from reflecting on the screen making them much better for office lighting or outdoors. The downside is that the contrast and brightness tend to be a bit more muted on these displays.

So, why is a glossy or matte display important to consider? Basically think of common areas where you will use a laptop. If they might produce a lot of glare, you should opt for something with an anti-glare coating if possible or the laptop should have very high brightness.

Graphics Processor

In the past, graphics processors have not been much of an issue for consumer laptops. The majority of users were not doing much graphically that required 3D graphics or accelerated video. This has changed as more and more people use their laptops as their exclusive machine. Recent advancements in integrated graphics have made it less necessary to have a dedicated graphics processor but they can still be beneficial. The primary reasons for having a dedicated graphics processor is either for 3D graphics (gaming or multimedia) and accelerating non-gaming applications such as Photoshop. On the flip side, integrated graphics can also offer improved performance such as Intel’s HD Graphics that support Quick Sync Video for accelerated media encoding.

The two major suppliers of dedicated graphics processors for laptops are AMD (formerly ATI) and NVIDIA. The following chart lists the current crop of graphics processors for laptop PCs from the two companies. They are listed in the approximate order of estimated performance from highest to lowest. If you’re looking to buy a gaming laptop it is important to know that they should have at least a minimum of 1GB of dedicated graphics memory but preferably higher. (Note that this list has been shortened to just the latest versions of the graphics processors plus one previous generation models.)

• NVIDIA GeForce GTX 1080M
• NVIDIA GeForce GTX 1070M
• NVIDIA GeForce GTX 980M
• AMD Radeon R9 M395X
• AMD Radeon R9 M485X
• NVIDIA GeForce GTX 970M
• AMD Radeon R9 M390X
• NVIDIA GeForce GTX 1060M
• AMD Radeon R9 M385X
• AMD Radeon R8 M470X
• NVIDIA GeForce GTX 965M
• AMD Radeon R9 M380
• AMD Radeon R9 M470
• NVIDIA GeForce GTX 960M

• AMD Radeon R7 M340
• NVIDIA GeForce 930M
• NVIDIA GeForce 920M
• AMD Radeon R5 M330
• AMD Radeon R5 M320
• AMD Radeon R5 M315

In addition to these processors, AMD and NVIDIA both have technologies that can allow certain graphics processors to run in pairs for additional performance. AMD’s technology is referred to as CrossFire while NVIDIA’s is SLI. While the performance is increased, battery life for such laptops is greatly reduced due to the extra power consumption.

Mousepads are a great way to help your mouse move more smoothly. Some of them even come with extra cushioning for support. Sometimes, they get dirty and need to be cleaned. To quickly clean a fabric or plastic-covered mousepad, rub it with a moist rag and some shampoo. Use a clean rag and water to rinse off the shampoo, then let your mousepad dry completely.

How to clean a mousepad?

Check out what your mousepad is made of. Usually it will be a spongy foam, covered with either a finely knit fabric or a plastic top. Clean it according to the type of surface. If the surface is fabric, try rubbing gently with a moist washcloth or rag and a bit of shampoo. Shampoo is a mild cleaner that’s gentle on most fabrics and on skin, plus you already have it. If your mousepad is plastic-covered, use any mild spray household cleaner and a cloth or sponge. Dish soap or shampoo will work just as well.

Rinse all the cleaner off the mousepad. Pat the outside of the mousepad dry. Allow the mousepad to dry thoroughly. Let it dry all the way through the foam before returning it to your desk.

Community Q&A

1.What should I do if the fabric mouse pad I cleaned now has a bump?

Try cleaning it again with hot water and soap, and then hang it to dry. That should stop bumps from forming as well as get rid of any existing bumps.

2.What if the mouse pad has a drawing on it? Should I worry about it at all?

It shouldn’t be a problem on plastic mousepads, because the plastic is covering the drawing. However, if it is a spongy foam fabric, you may want to be gentler when cleaning.

We often fixate on smartphone battery life, but most laptops still don’t have all-day battery life. Rather than tethering your laptop to an outlet, here are some ways to squeeze more life from your laptop’s battery.

None of these tricks will turn a laptop without much stamina into an all-day workhorse, but they’ll help you go without an outlet for a while longer. Pay particular attention to your laptop’s display—that’s a big battery sucker.

Use Windows 10’s Battery Saver Mode

If you want to extend your battery life without thinking too much about it, enable Windows 10’s Battery Saver mode. Windows automatically enables this feature when you’re down to 20% battery by default, but you can manually enable it whenever you like. So, if you know you’ll be away from an outlet for a while, you might enable it at the start of a long day.

Battery saver performs a few tweaks automatically, like limiting background activity and lowering screen brightness to achieve longer battery life.

To enable Battery Saver mode, click the battery icon in your notification area and drag the Power mode slider to the “Best battery life” point on the left.

Reduce Your Display’s Brightness

The biggest battery drain on any modern portable electronic device—whether it’s a laptop, smartphone, or tablet—is the display. Reducing your screen’s brightness is a simple way to squeeze significantly more time from your laptop’s battery.

On a typical laptop, you’ll just need to press the brightness buttons on your laptop keyboard (on some laptops, you may need to hold the Function (Fn) key while pressing the brightness buttons). The lower the brightness level, the longer you can use your laptop on battery power.

On Windows 10, you can also open the Action Center by clicking the notification icon on your taskbar and click the brightness icon to adjust brightness (click “Expand” if you can’t see it). You can also head to Settings > System > Display and adjust the slider here

Check Which Applications Are Using the Most Battery on Windows 10

Windows 10 allows you to see which applications are draining your battery the most. It does this by tracking CPU usage over time, then listing which programs are using the most power. This feature isn’t available in Windows 7.

To access this list, head to Settings > System > Battery > Battery Usage By App. This screen will show you which applications are using the most battery. This doesn’t necessarily mean the application is bad—the applications you use the most will probably have used the most battery power, of course. But you may want to consider switching to more power-friendly applications if something is unusually heavy, or close background applications that seem to use a lot of power even when you’re not actively using them.

Turn Off Your Screen and Go to Sleep Sooner

Since the display uses so much power, it’s important not to have it on longer than necessary. You can configure your laptop to automatically go to sleep sooner when you’re not actively using it—or at least turn off its display to save power.

This won’t help your battery life if you’re actively using the laptop the whole time, or always put it to sleep immediately when you’re done, but it can ensure your laptop doesn’t waste power by running for too long when you step away.

Disable Bluetooth and Other Hardware Devices

Hardware devices you don’t use can also waste battery power for no good reason. For example, if you never use any Bluetooth accessories with your laptop, you can turn off the Bluetooth hardware radio to eke out some more battery life. (f you do use Bluetooth accessories regularly, toggling Bluetooth on and off may not be worth the trouble, as the Bluetooth hardware in modern laptops is more power efficient than it once was.)

Tweak Your Power Plan

On Windows 7, you can save energy by selecting the “Power saver” Power Plan from Control Panel > Hardware and Sound > Power Options. This isn’t necessary on Windows 10, as you can just use Battery saver mode instead.

You can change a variety of settings from the Power Options window that appears, including configuring your laptop to power off its hard drive more quickly and telling your computer to slow down the processor rather than turning on the fan if it becomes hot. Both of these behaviors will save power. The default settings should be fairly optimal if you select Power saver mode, but you can make the settings even more aggressive in some areas, if you like.

Run the Windows Power Troubleshooter

Windows 7, 8, and 10 include a power troubleshooting tool that will scan your system for common battery drains and automatically fix them. For example, this tool will automatically decrease the time before the display dims if it’s too long, or disable the unnecessary screensaver feature if it’s enabled.

Lighten Your Software Load

To save power, make your computer do less in general. For example:

• Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
• Run fewer programs in the background. Examine your system tray for programs you don’t need and uninstall them or disable them and prevent them from automatically starting with your computer.
• Reduce CPU usage. If you use heavy programs that have your CPU doing a lot of work all of the time, your CPU will use more power and your battery will drain faster. Running fewer programs in the background can help with this, as can selecting lightweight programs that are easy on system resources.
• Avoid maxing out your RAM. If your computer fills its RAM and needs more memory, it will move data to the page file on its hard drive or SSD, and this can drain battery power. This shouldn’t be as much of a problem on modern computers with a decent amount of RAM. If your laptop’s RAM is full, try to make more RAM available—close programs running in the background or even upgrade your laptop’s RAM.

The less your computer has to do, the more power it can save. You can find more information about CPU and RAM usage in your Task Manager.

Laptop screens tend to collect dust, food particles and other debris that starts to look unattractive after a while. It’s important to use very gentle supplies to clean your laptop screen, since the LCD surface is easily damaged. Using a microfiber cloth and a simple solution of water and vinegar will do the trick if you don’t want to purchase a special screen cleaner.

1.Cleaning the Screen With A Microfiber Cloth

First, turn the computer off and unplug the power adapter and battery. Cleaning a screen that’s in use can result in permanent damage, so err on the safe side and turn everything off. Don’t just put it to sleep. Then get a microfiber cloth. This is made with a type of fabric that doesn’t produce lint, in addition to being very soft. If you use a washcloth, T-shirt or another type of cloth, it could leave extra debris on your screen or scratch it. Avoid using paper products as well. Never use a napkin, paper towel, toilet paper or another paper product, since these are scratchy and will damage the screen. Then wipe the screen gently with the cloth. Using one sweep of the cloth should take care of any dust and loose particles on the screen. Wipe gently without exerting much pressure, since if you press too hard you could damage the screen. When you wipe with gentle circular motion, you’ll be able to lift up some of the tougher spots. Never scrub the screen, or you could cause pixel burnout. Clean the laptop frame with gentle cleaning solution. If the area around the screen is dirty, you can use a standard household cleaning solution and a paper towel; just be very careful not to let it touch the screen.

2. Using a Cleaning Solution

First, turn the computer off and unplug the power adapter and battery. Since you’re using a liquid to clean the screen in this method, it’s important to turn off the computer and unplug it from the outlet. Create a gentle cleaning solution. The ideal solution is plain distilled water, which contains no chemicals and is gentle on the screen. Make sure you use plain white vinegar, not apple cider vinegar or any other kind. Put the solution in a small atomizer bottle. This is the type of spray bottle that you push from the top to get a fine mist, similar to a perfume bottle. Pour some of the solution into the spray bottle and screw on the top. Don’t use this to spray on the screen itself, however. Apply a minimal amount of the solution to a microfiber cloth. A static-free, fiber-free cloth works best. Remember not to use regular cloth, since this could scratch the screen. Do not soak the cloth; you just want to get it moist, which is the purpose of using the atomizer bottle to wet it. A wet cloth can drip or run when cleaning the screen and the solution can weep behind the bezel and permanently damage your screen. Try applying the solution to just one corner of the cloth at a time, to make sure you don’t get it too wet. Wipe the cloth against the screen in a circular motion. Rapid circular movements generally eliminate streaks. Apply a gentle and even pressure to the cloth. Use only enough pressure to keep the cloth in contact with the screen.

A common question we tend to hear all the time is “Why does my laptop battery run down so fast?” Below we present a fairly detailed explanation for this and provide a step-by-step guide you can follow to help you control the situation. We can use the “battery calibration” method to make the best notebook battery power . Here are two ways to correct laptop battery.

First. Standard correction method: laptop battery calibration function.

Many brands of laptops in the which have integrated battery calibration procedures, the general English saying is called “Battery Calibration”, that is, “battery power proofreading.” Directly into the will be able to complete the battery calibration operation.

1, Boot, press F2 after entering the boot screen to enter the menu; by left and right arrow keys, select to enter the power menu.

2, Into the power menu, you can see the “Start Battery Calibration” option, select it and press the Enter key to execute.

3, Then the screen will turn blue, and English tips, request the laptop’s power adapter plugged into the battery. When the battery is full, the screen prompts the user to disconnect the power adapter. After the laptop began to continue to discharge the battery, until the battery is exhausted.

4, This process takes some time, and other batteries automatically shut down, and then connect the power adapter to charge the battery, but do not boot. After charging is completed, the battery calibration process is completed.

Second, Manual correction method: Let the laptop boot naturally discharged.

Some notebooks in the can not find how to find the battery calibration options. Is not such a laptop can not be battery calibrated it? Through some of our manual settings, so books in the normal discharge until the automatic shutdown.

1, Notebook in the operating system, enter the “power options.” Select “Always on” for “Power Schemes” and set “Shut Down Monitor”, “Shut Down Hard Drive” to the minimum time, and system standby to “Never”.

2, In the “Power Options” “alarm”, cancel all alarm options, the purpose is to let the battery completely depleted until the shutdown.

3, After setting, close all applications, turn off WIFI, unplug the power adapter, battery powered. Do not do anything until the battery is exhausted and shut down automatically. After the discharge is complete, connect the power adapter, the battery is full, then completed a battery calibration.

Third,In addition, if it is Windows7 users, or power management software is not good settings, you can enter the laptop’s BIOS, the laptop has been open, at the same time to unplug the external power supply, waiting for the notebook to run out of power automatically shut down.

If you give the laptop battery calibration battery life is not yet obvious, it may be caused by the aging of the battery itself, if the notebook battery life is normal, it is not recommended to use the battery calibration.
