Battery calibration is a technique to fix incorrect battery statistics showing and giving incorrect battery runtime remaining. We recommend this as a regular laptop cleaning ritual. The process of calibrating a laptop battery isn’t difficult – it’s basically a method of fully discharging the battery to empty and then fully charging it to 100%, and some companies even offer integrated programs to do this for you. If you want to do this manually, then you can do this too. All newly purchased laptops and tablets should be calibrated immediately after purchase. This helps your laptop get an accurate reading of the remaining battery runtime. Lack of calibration, battery ratio readings will be inappropriate, and according to Apple, your computer may behave strangely — shutting down suddenly even if a new battery is “suddenly” partially charged, or even if the battery says it’s almost dead, you Your laptop will also take up your laptop for a long time.
Is Laptop Battery Calibration Necessary?
No matter how well-used your laptop battery is, its capacity will definitely decline over time due to unavoidable factors such as normal usage, battery aging, and heating. If the battery is not allowed to run from 100% to 0%, the battery’s gauge will not recognize the actual charge in the battery. In general, manufacturers recommend calibrating batteries every 2 to 3 months, which helps keep battery readings correct.
In fact, if you’re not too concerned about your laptop’s battery reading being completely correct, you really don’t have to do it very often. However, if you don’t calibrate your battery often, you may eventually find your laptop shuts down abruptly while you’re using it, without any prior notice. When this happens, it’s time to calibrate your laptop’s battery.
How do I calibrate my laptop’s battery?
Here’s how to calibrate your laptop’s battery with a step-by-step guide:
i. Standard calibration
Many companies offer built-in calibration routines integrated into the BIOS.
Turn on your laptop and press F2; select the power menu in the top tab.
Select Start battery calibration and hit “Enter”.
Wait for the display to turn blue.
The battery will continue to be discarded until fully discharged and the system shuts down. After that, plug in the adapter to fully charge it; when the battery is completely replaced, the calibration process is complete.
ii) Manual calibration process
If the standard process does not work for your laptop, you must do it manually
After booting the system, go to “Power Management Settings” on the laptop.
Select Change plan settings.
Go to “Change advanced power settings” and press “Battery”. Select “Critical Battery Operation” and select the “Hibernate” option. Also, select “Critical Battery Level” and set it to 5%.
After updating all settings, close all running applications. Disconnect it from the adapter and turn it off when fully discharged.
After a few hours of pause, plug in the adapter again and charge the battery to 100%.
Remember, if you want to calibrate the battery when the laptop is not in use, then you should set the following options to “Never”, ie:
dim the display
Turn off the display
put the computer to sleep
Let the laptop sit for a while until it shuts down automatically. After calibration, make sure to configure all of the above power settings to normal values before using the laptop again.
So, here are two ways to calibrate a laptop battery. You can choose the one you think is the easiest and most convenient. Or if the first method doesn’t work, try the manual method.
