HP Z420 shutdown after startup.
The hdd lights up green. Powerbutton is not working.
No matter how long I hold the power button (20seconds), the computer will not turn on, only the green HDD LED will glow continuously green.
When I pull the power cord, the HDD LED will stop glowing after 10 seconds.
When I reconnect the power cord, the computer will automatically turn on and after 2-3 seconds the computer turn off. The green LED lights up again.
No beeping.
Battery removed from the motherboard, graphics card & ram removed, did not help unfortunately.
Does anyone have an idea what it could be?
Thanks!
