HP Probook 6555b BIOS Admin Password Issue

[johnreid]

Hi,

Im trying to update the BIOS on my HP Probook 6555b, but get prompted for an admin password, which i do not know.

I have removed the battery and the RTC battery, however when i start backup i get the below error and the default admin password gets restored.  Is there a way to reset the Admin BIOS password please?

The CMOS checksum is invalid.
The CMOS will be reset to the default configuration and will be rebooted.
Please check your BIOS Setup options to see if they changed.
CMOS Reset (502)
ENTER - Reboot the system

Contact HP.

Or download these files.

Insert clean USB flash drive.

Then run USB Image tool.

Choose the flash drive then click on RESTORE.

After restore remove flash drive.

Insert flash drive into locked laptop and boot.”If HDD is installed remove before booting.”

At C:\OUTPUT   type CD..   “Then hit enter”

Type HPBR   “Then hit enter”

First thing is to save your settings.

Select #3 re-program.

Press “S” to save system information.

Type HPBR and hit enter.

Since your model is not listed select “SHOTGUN.”

After reboot repeat “SHOTGUN” a second time.

Let me know the result so I can update my list.

Some instructions here. “If you cannot boot from USB there are instructions to make a bootable HDD.”

Hi, thanks for the instructions, i have tried to follow them, after removing my HDD when i come to boot from an external drive nothing is listed, im assuming this has been disabled in the BIOS. is there a way around this?

@johnreid

Then you would need to make a bootable HDD.

Scroll down to where it talks about LOCKED BOOT ORDER.
