I am using a Dell n5050 laptop, recently I noticed that I have a problem with my laptop. Namely, the power LED always stays on after shutting down the laptop.

I've found two options:

  1. long press of the power switch will turn the LED off
  2. remove the battery will also turn it off

How can I resolve this issue?

This LED reflects the fact that your laptop is plugged into the power network. Unplug it and the LED will be switched off.

The battery charge continues after you shut down your laptop. The long press on the power button stops this charging
