Why does my laptop power button and charge light come on & off nonstop

Hi @yezidvk

Here's a link that will help you to find out what's wrong.

Click on Identify the Notebook light or beep code and then find the link that matches the colour pattern that the power button and caps lock button lights make on your laptop.

If the battery charge LED indicator light turns on and off while AC power is connected and the battery is still charging, the battery is simply in a low-charge state. The Windows battery property shows that the battery is Online - discharging. This occurs because of the battery's charging cycle.
