Could someone help me what to do and how to do it? I bought an HP probook 650g3 laptop and found a locked bios at home. I tried various tutorials, none of them helped. I finally found a forum where I could unlock the bios. I downloaded RCUnlocker v1.0, I move the bin file to it, it says bios unlocked. After restarting the laptop, where I try f10 in the bios, it still needs a password. What am I doing wrong?

Use the search engine before asking questions. It has already been commented on in earlier posts.

I desoldered the chip and soldered it to the programmer board. I tried other firmware with which the laptop does not respond to the power button. At the same time, my firmware turns it on a little, but with a black screen. Visually I do not see any damaged components and the chip is sealed correctly. When turned on, there is a 3.3V (8 pin) power supply. I'm interested in the correctness of my dump, I'm afraid there's something wrong there.

[Vesko356]

Should work, most probably you didn't program or solder the chip properly. Check surrounding area for moved/knocked components.
Don't use a clip, erase the chip before programming the unlocked dump, use verification.

Hello. I have a problem with the administrator password on the HP Probook 650 G2. I tried with HPUnlocker and RCUnlocker and the laptop does not work. It turns on, after 30 seconds the fan spins strongly, the screen is always black. Can anyone help me?
I returned the password-protected dump, and everything was the same. It seems I initially read the firmware incorrectly...

I tested this tool with an HP 420 and it removed the password without problems.

Thanks a lot!!!

Re: HP BIOS unlock tool

Your first problem is that you should be using RCUnlocker instead of this outdated tool

Re: HP BIOS unlock tool

Hi,
i've a Zbook G9 with Xe and discrete graphic installed. In BIOS there is only UMA and Hybrid option available, so is there a way to unlock the discrete card alone?
In my G7 i can set disdrete in BIOS and completely disable optimus, but in G9 no such option available.
Ive tried with UEFITool and IFR Extractor with RU.efi to change a Variable but ended with a blackscreen with backlight. reset cmos back to normal again.
Any help to unlock the hidden option is appreciated. THX in advance. XD
