Hi,

At the password screen, hit enter 3 times and you should receive a 'halt code' - post back with this code.

Hi,

Your notebook is producing a hexadecimal halt code which is stored in ram as a 'one off' and will be re-calculated after a reboot.  This indicates you have one of the later AMI bios's and unfortunately none of the current code generators will work for this - there are a couple of options.

1.  Contact HP Support starting on the link below.

2.  Alternatively, you may still be able to remove a power on password from the machine by removing the rtc cell ( leave the power board connected ) then hold down the power button for 60 seconds before re-inserting the rtc.

The bad news is that the rtc is on the 'wrong' side of the system board so will require quite a lot of disassembly - see Page 105 of your Maintenance & Service Guide.
