G62 - 5 sec boot-loop and black/no screen

‎06-03-2011 06:31 AM

Hello,

i own a G62-a54SG. Starting the laptop causes and endless boot-loop (restarts every 5 sec) without showing me any screen information! The only way i can see some info is when i unplug the mainboard-3V-battery for 30 min and get a bios checksum + reset screen for 5 sec until reboot-loop.

 

I tried a hard-reset (60 sec powerbutton without akku etc.) with no luck and i tried to reset the bios over WinKey + B & usb, but the laptop restarts before it's even trying to load some data from the usb flash drive :smileysad:

 

Insyde BIOS F.28 is installed (newest version)

 

Thanks for help!
