Solved! Asus wont boot

Sep 13, 2021

It is about an Asus K55VD that dont wanna boot.
When I start the laptop nothing shows, just the lights and nothing on screen.
Connected another monitor to see if that is the problem, but still just a black screen.
I try to change the RAM memory but nothing.

And something interesting is that sometimes it starts. But when the num lock light stay green it wont start. Does it try to tell an error?
So 10 times is not starting with the num lock light on and after that 1-2 time starts and the num lock light is off when the boot starts.

Do you have any idea?
Thank you
The NumPad indicator is probably just telling you when it is passing the CMOS stage of booting up. Try resetting the CMOS battery. Take it out, wait 5-10 minutes, and put it back in.
