7740g bios recovery

Gold1969

Updated the bios in a Aspire 7740g from version 1.15 to 1.16 but with poor result. It flashed everything correctly, but when rebooting, nothing... Black screen.

The fan starts and stops after a few seconds, led's indicating that it's "alive", and I've tried the crisis recovery tool with bios 1.15 or 1.16. First with USB-drive (tried all ports), then on a CD-R. No sign of activity on the USB, but the CD-R spins up, head reading and can hear it working for 30-60 sec., rebooting, but then - nothing.

I have tried all key-commands, suggested on the net. Win+ESC, Win+B, Fn+ESC, Fn+B, but - nothing. (Power off, plug and battery removed, hold keys down, power connected and power on.....)

 

The battery is dead and removed, but it doesn't seem as it matters anyway?

 

Anyone? What kind of bios does this Aspire have? Any other key-commands I should try? Other Ideas? It seems as the Recovery Boot Block is there somehow, as the CD/DVD-drive spins up and sounds as it's working.

 

Hope you can help!
