How to calibrate the battery of a laptop PC in Windows 10, 8.1 and Windows 7? This is what we will see in this article. In principle, the method is the same regardless of the device you are using. Whether it’s a MacBook or a Linux or Windows laptop.
Over time, battery life naturally deteriorates. But it often happens that the battery level indicator plays dirty tricks by displaying percentages that are out of phase with the actual range. A microprocessor incorporated into the batteries lets you know in real time the amount of energy available to them. It is a component on which operating systems are based to provide visibility into the level of autonomy that remains to Laptops, smartphones and any device.
If your computer displays a strange change in the battery level, it is not necessarily due to the degradation of the real autonomy. Maybe this is a sign that it’s time to calibrate the battery from the PC.
How to calibrate the battery of a laptop?
Lithium-ion batteries in portable PCs most often encounter calibration problems. And for good reason, we are more inclined to leave them plugged into the mains most of the time. Some users even hate seeing their battery level drop below 50%. This kind of behavior can disrupt the indicator which ultimately no longer manages to correctly assess the amount of energy that it actually remains in the battery.
As a result, it may happen that your PC starts to shut down suddenly without warning of a low battery level. For example, the percentage can go from 30 to 0% in just a few minutes or even seconds. Uneven evolution of the battery level display is due to a calibration problem. Here’s how to calibrate the battery of a laptop PC running Windows.
Windows 10: steps to recalibrate your PC battery
The principle is the same as when it comes to calibrate the battery of a smartphone or other device using a Li-ion battery. It is based on a full discharge and recharge cycle.
- Plug in the device and let the charge level rise to 100%
- Go to Windows power management settings by right clicking on the battery icon. Alternatively, go to Settings> System. In the Menu on the left, click Power and standby. In the menu on the right this time, click on Additional power settings.
- On the power options page, click Choose when to turn off the screen in the left menu
- Click on “Change advanced power settings”, then expand the options in the “Battery” section. Make sure “Critical Battery Action” and “Critical Battery Level” are set to “Hibernate” and 5% respectively.
- Unplug the charger and let the PC run until it automatically goes into hibernation. During this time, you can continue to use your computer normally.
- Once the PC is on standby, plug it back in, turn it on and let it recharge to 100% without unplugging it in the meantime.
It does not take more to calibrate a battery in Windows. And if you plan to perform the operation at a time when you are not using your computer, make sure it is not set to automatically go to sleep after a few minutes. To do this. Still in power options (Choose when to turn off the screen), set the “Turn off screen” and “Put the computer to sleep” actions to “Never” when the computer is on battery power.
In doing so, the PC will not automatically go into hibernation until the battery reaches 5%. Do not forget to come back and set the screen to turn off and automatic standby to the desired time after the process is complete. And to finish, it is important to repeat this process regularly. No periodicity is required. However, we recommend that you do this once to three times a year.
