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 - so at the moment your options are down to Contacting HP support.

or

You can still remove a power on password by removing the rtc cell, then holding down the power button for 60 seconds before re-inserting the rtc - If you need the Maintenance & Service Guide for your machine, post back with the Model No.

Hi,

Unfortunately, as I mentioned previously, none of the current generators will work for a hex halt code - you can remove the password by removing the rtc as described in my previous post or submit a request to HP via the web portal starting on the link below.
