How to Recalibrate Your Laptop Battery

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.

While your computer may have a preinstalled app for you to use, it is always helpful to understand how to do so manually. Below are some easy steps to get your battery recalibrated in no time.

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
You want the battery to work as long as it possibly can. To do so, find “battery” in “power options” and make sure it is on “hibernate.” Then, check “low battery action” and ensure that all options are set to “nothing.” Under “critical battery level,” choose 5 percent.

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.

Revert Settings
Once you’ve completed the previous step, go ahead and change your settings back to the way they were before. You might consider switching off the screen sooner or even get your computer to sleep after ten minutes to help you conserve power. But this is all up to you and your preferences.A
