To fix various driver issues on your PC, you will need a dedicated tool to find the freshest and the original drivers. You can use PC HelpSoft Driver Updater to do it in 3 easy steps:
A typical laptop battery becomes weakened over time. This is especially common tolaptopsthat are used rigorously on a daily basis.
One key indicator of a weakening laptop battery is the discrepancy betweenbattery life readings and actual battery life.
To correct this discrepancy and extend the lifespan of your battery, the simple solution is battery calibration. And we’ll be showing you how to calibrate laptop batteries in this article.
However, a weakened laptop battery (that has not been calibrated) could cause serious confusion.
For instance, on a typicallaptop, the remaining battery life could read 2 hours, which, in actual sense, is only 30 minutes or thereabout.
Hence, while your laptop battery is showing you2 hours remaining, you get stunned after only 30 minutes – when your battery suddenly drops to 10%, and eventually powers off.
To avoid such confusion and ensure accurate readings of battery life (on alaptop), the ultimate solution is to calibrate your laptop battery.
Follow this article, as the Windows Report team provides you with tips, tricks, and software solutions, which can be employed to calibrateWindows 10laptopbattery.
How do I calibrate the battery on my Windows 10 laptop?
Some high-performance laptops come with a built-in battery calibration tool, which can easily be used to calibrate a laptop battery.
However, a number (in fact majority) of laptop brands are not equipped with this calibration tool.
Nevertheless, there is no cause for worry, as there is a simple trick you can adopt to manually calibrate your laptop battery, and boost its lifespan.
There are three solutions that you can use to calibrate your laptop battery: manually, using BIOS, or using third-party software.
For convenience, we’ll be showing you how to execute this manual calibration, in the next section of this article.
1. Calibrate the laptop battery manually
To manually calibrate a laptop battery, the first line of action entails changing thelaptop‘s power settings.
At this point, you would be required to change the power settings. This will prevent yourlaptopfrom automatically going into sleep/hibernation/power saving mode, after a few minutes of inactivity.
Once you’ve changed the power settings as appropriate, move to the next stage.
Connect the charger and power the battery until it is fully charged. Leave the charger plugged in (after the battery is fully charged) for a few minutes or hours (to enable it to cool down).
Remove the charger from yourlaptopand allow the battery to drain down (discharge). Once the battery is completely drained, yourlaptopwill go into hibernation or completely power off.
Reconnect your charger, and charge the battery up to 100% again.
Note:You can use your computer during the recharging process, but it is better to leave it still.
Once yourlaptopbecomes fully charged, the manual calibration process is complete. Yourlaptopshould now show normal battery life readings.
After the whole process, you can reset yourlaptop‘s power settings (back to the original settings), or if you like, you can leave it as it is.
2. Calibrate the laptop battery using BIOS
Some Windows laptops come with a pre-installed battery calibration program, which is embedded in their BIOS.rnrnIf your laptop has a built-in Battery Calibration program (in its BIOS), you can use it to calibrate the battery.
1. Power off your laptop, and power it on again.

-
Follow the on-screen command and plug in your laptop charger.
-
Once your laptop‘s fully charged (100%), disconnect the charger.
-
Allow the battery to discharge from 100% to 0% until it automatically powers off.
-
Reconnect the charger (do not boot your system while it is charging).
-
Once it’s fully charged, the calibration process is complete.
-
You can then unplug the charger and reboot your system.
Also, if you encounter acorrupted battery prompt, you should address that quickly.
3. Calibrate the laptop battery with a third-party tool
There are special software solutions, exclusively designed for calibrating laptop batteries.
In this section of the article, we will be looking at two prominent battery calibration software that is compatible withWindows 10 laptops.
Battery management software can analyze and improve your battery. Many of these tools can give you comprehensive reports regarding the battery temperature, autonomy capacity, and more.
On top of that, you can set them up to help you optimize your settings for longer battery life. They can detect what process in your system is draining your battery the most and find quick and safe fixes for it.
AIDA64is a popular hardware detection tool for Windows laptops that offers diagnostic functions and support for overclocking.
It can be employed to speed up the discharge process of a laptop battery and facilitate its calibration.
This software is compatible with all 32-bit and 64-bit Windows editions, including Windows 10 and Windows Server 2019.
Aside it is monitoring sensors in real time, it can also gather accurate voltage, temperature, and fan speed readings, while its diagnostic functions help detect and prevent battery issues.

No matter how strong your laptop battery is, it will eventually become weakened, with time.
The battery weakening process is gradual, such that you’ll hardly notice. At this point, battery life readings suddenly become inaccurate, throwing you into a state of confusion.
To prevent/avoid such a situation, you have to calibrate your laptop battery, preferably once every 2/3 months. And we have described, comprehensively, how to calibrate laptop battery in this article.
We hope you found these ways to calibrate your Windows 10 laptop battery useful. For more suggestions or other questions, feel free to visit the comments section below.
