Laptops have two types of batteries.

  1. COMOS Battery
  2. Power Laptop Battery

Today we will talk about both. First of all, let me tell you how to remove the Comos battery from the Acer laptop. And then, I will explain How to Remove The Power Battery From Acer Laptop?

The CMOS battery is your power source for the computer’s flash memory. A CMOS battery stores and maintains BIOS settings in the absence of electricity. Your CMOS battery is mounted on your motherboard, just like a regular watch battery is. If you need to remove your CMOS battery, you’ll need a screwdriver to do it, and it will take about ten minutes to do.

But on the other hand, a Power Battery is a normal battery that is used for powering up the laptop. It is big in size and it is rechargeable. whereas the CMOS battery is very tiny in size and is not rechargeable, it is a cell type of battery actually. The power or main battery of the laptop is easily removable with some clips or mechanical buttons, yes most laptops nowadays come with a non-removable battery.

Now, let’s discuss the detailed methods of removing both of these batteries:

Often, the Battery reports false values, which can result in it stopping charging or dying unexpectedly. It can be fixed by “calibration,” which drains and refills the Battery completely.

  1. Shut down the Aspire.

  10. Click Start Button & type “cmd” without quotation marks.
  11. To get “cmd.exe” to run as an administrator, right-click the results, pick “Run as administrator,” and then enter your username and password.
