Red power light just started blinking, have plugged into wall most of the time, never lose charge. What does it mean?
I believe that the blinking red light indicates a failing battery or power adapter, if I recall correctly from a past repair. Sorry that I can’t be more informative, I haven’t had the opportunity to work on many Asus notebooks.
@madalitsokhuvulo What is the model number of the laptop? Create a Win 10 battery report and check on the status of the battery. Have you checked that the charger is OK by trying another compatible charger or measuring the charger’s output at the plug that plugs into the laptop?
