My HP Pavilion dv9000 laptop (running Windows XP) won't boot - it just keeps going into a restart cycle.
I've tried to turn it on without the hard drive inside but I still get to the same rebooting sequence. It doesn't even show the BIOS details before it restarts. I'm also unable to boot into safe mode as the computer doesn't get that far before restarting.
The restarting happens within a matter of two seconds - it doesn't have time to display anything on the screen hence why it does not display the BIOS. This keeps repeating until I take the battery out. Not much more happens than that.
