  • Shut down the laptop.
  • Press the power button to turn it on again.
  • Once the laptop starts- press the Esc key or whichever key your laptop requires to enter the Start Up menu.
  • In the Start Up menu, navigate and select System Diagnostics.
  • A list of various tests will appear on your screen. Navigate and select Battery Test.
  • Once you navigate the Battery Test, plug in the charger before starting the test.
  • Click on the Start Battery Test button and wait.

  1. The battery is working fine.
  2. Expect a drop in battery performance.
  3. Very Weak. Expect a significant drop in battery performance.
  4. Install a new battery.
  5. No Battery. The battery might not be attached properly.
