I have notebook Fujitsu AH530 GFX. His BIOS started to error with boot and fans worked bad (much warmed).
I then wanted to change it BIOS. I changed it wrong for AH530 (not GFX), and said that it is succesfully changed all steps doed and turned off normally. Then i saw that it is wrong Bios because it doesn't shows enything and it emit "beeps" for changing BIOS. I turned it off on power button 2 times. Next time i press power button to turn ON only start HD, Fan and DVD for 1 sec ,then stay some time on then suth down (i looked in other comments but on all theirs PC reboot, but mine go off)
