Contact HP and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

Phone >> http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html

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

Do not try removing the RTC battery.  It will not remove the password, but it will reset the clock - as SMC files are time coded, a large disparity between the system clock and the time encoded in the SMC will cause it to fail.

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 an 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.

Select   “FIRST RUN”

Then select model.

After reboot repeat same as above but this time SELECT, “SECOND RUN”

If you cannot boot from USB flash drive use Options in the Image tool to build a HDD.

Then use the drive to boot the program on the locked laptop.

Hi thanks for a quick reply.

I read your previous post about the same issue. I am aware of the "calling the hotline solution " but it is not worth the price.

I will go with your solution, do I need all of the files ?

I will post the final results of the unlocking procedure.

Thank you

"Edit, The procedure worked well, updated bios firmware to latest . I now have an unlocked bios and also gained a more stable configuration. The fans spinned down to a more comfortable noise level thanks to the update"

Thanks mate
