Resetting the Power Management System

When your laptop battery is not charging, resetting the Power Management System (PMS) might help resolve the issue. It can clear out any glitches or errors that are hindering the charging process.

How to Reset the Power Management System:

  • Step 1: Shut down your laptop and unplug it from the power source.

Calibrating the Battery

When it comes to dealing with a laptop battery that’s not charging properly, Calibrating the Battery is a crucial step that can help reset the battery gauge. This process involves helping the operating system understand the battery’s true capacity, which can sometimes get out of sync due to frequent charging or long periods of inactivity.

To begin calibrating your battery, follow these steps:

  • Charge and Discharge: Start by fully charging your laptop battery. Once it’s charged, disconnect the power adapter and use your laptop until the battery is completely drained and the device shuts down by itself.
  • Rest Period: After your laptop has turned off, allow the battery to rest for a few hours. This rest period is important to ensure an accurate calibration.
  • Plug In and Recharge: Plug in your laptop and allow it to fully recharge without interruption. Once your battery is fully charged, the calibration process is complete.
