How to remove BIOS Admin password from HP laptop

[dominykaspetronis]

Hello,

my laptop wasn't used at all for like 3 months. After I tried to play one game I found out that my dual graphics second video card isn't working and not even appearing on device manager (AMD drivers don't see the video card). I remember that when I bought this laptop there was an option in bios which allowed me to turn on dual graphics. When I tried to access BIOS it asked me for Administrator password. I don't remember setting it at all. After this big break I changed the battery, power supply, power jack of my laptop. I tried removing CMOS battery - didn't work. Filling three wrong passwords doesn't give me any code so I couldn't search for default BIOS password.

What are the chances that replacing those parts could have affected my laptop BIOS or causing my graphics card not to work? Power supplies outputs perfectly match. Graphics card is AMD RADEON HD8750m. I appreciate any help from You guys.

For the HP ProBook series, the BIOS password is stored in non-volatile memory. So you can't clear it out from CMOS.

Most likely you'll have to call HP support and have them generate it for you over the phone. In some cases, you have to validate ownership of the laptop itself to prove it doesn't belong to a company as an asset.
