Hi,
me was offered some updates by the HP support software, including a BIOS update.
Everything went perfect. The PC shut down, update started and was checked, all OK. Then the PC rebooted and beeped 8 times. The monitor stays dark.
Then i googled on another PC and tried a start with the Windows + B (V) key. The keyboard does not light either, so keystrokes do not seem to be possible.
Then tried a BIOS update via USB stick. Without success. It seems like the PC is restarting every few minutes.
I have already disconnected the PC from power, removed the battery, memory and HDD and deleted the CMOS with the jumper.
What else can I do?
