Manufacturers generally recommend calibrating the battery every 2 to 3 months. This helps keep your battery readings accurate. You may need to do it sooner if your laptop dies on you without any previous warnings.
Top Up Your Battery
You need to top up your battery first, so plug in your laptop and let the battery charge. When it’s at 100%, leave the laptop plugged in for a few hours so the battery has a chance to cool because heat can give you inaccurate results.
Set Up Battery
Find “Power Options” in Windows (you can search for it in the search bar in the start menu or by right-clicking on the charging icon in the taskbar) and select Balanced. Then click on “edit plan settings” and jot down what each of the boxes under “on battery” is set as. Change them all to “never,” then “change advanced power settings.”
Set Up Hibernation Point
Let Your Battery Drain Then Recharge
Once you’ve clicked in “power options,” select “save changes” under the “plan settings” window. Now you can discharge your battery by unplugging your laptop. Go ahead and use it as you normally would, or leave it on to discharge. If you’ve set everything up correctly, your laptop will hibernate at the lowest level you have set your battery at. Your screen won’t turn off, and it shouldn’t enter sleep mode.
Now all you need to do is wait before charging it back to 100%. Usually this takes at least 5 hours, or you can even leave your laptop overnight. You can still use your laptop as you normally would.
