Re: Forgot bios password

Hi@Delava50,

 

Welcome to HP Forums, this is a great place to get support, find answers and tips,

 

Thank you for posting your query, I'll be more than glad to help you out.

 

As I understand the computer is asking to "power on password" and you need assistance with the same,

 

You would have to contact HP phone support for a hardware service as the motherboard may require a tattoo/Bios Flash.

@Delava50

 

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.

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

 

Or download these files.

 

https://www.dropbox.com/sh/zu4kdgxm052l87d/AAAMi-k​​fX4AVH8oTCbsOM4X9a?dl=0

 

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.

 

Select   “FIRST RUN”

 

Then select model.

 

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

 

REO
