User/ BIOS administrator forgotten - HP Compaq 6735S

[Dane_Cas]

Hi,

My partner currently owns a HP6735s laptop, however she's added a password at boot-up and cannot remember it. The laptop was purchased second-hand, she's not sure of the BIOS Administrator password and she isn't enrolled in HP spare key. The warranty expired a while ago now (2009!), so I'm don't think it's going to be covered; just a hunch though. 

Any ideas on how I can look to remove either the user or administrator password at all without opening up the laptop and flashing the BIOS chip?? 

Thanks in advance!

Contact HP.

When talking to the HP rep ask them to escalate your service request.

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.”

I've also succeeded in using this with an HP EliteBook 8440w.

Two passes of SHOTGUN.
