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 - surprisingly, you can usually still 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 127 of your Maintenance & Service Guide.
The only other option would be to Contact HP regarding this.
Regards,
DP-K

Hello,
I have disassembled the laptop and removed the battery. Then i have put it back together and when turning it on i got the following message.:
The battery has been removed and the BIOS will be reset.
Then it goes to the HP logo, reboots automatically, goes back to the HP logo and reboots automatically?????????
It keeps doing this.
Best Regards,
Stefan

Hi Stefan,
You need to re-insert the rtc battery, then re-assemble the notebook before powering on.
