HP Omen 15-dh0052nf power-on & bios password

[Nopslide]

Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set.

Upon reboot, what was my surprise to still see the password request.
Now I still get the password prompt on power on, but my actual password doesn't work anymore! Even trying: password, 123, 12345678, admin…. Nothing work.

I tried the Win+B solution: the cmos bios was reset twice but I still get the password prompt... there is no more clock battery (apparently stored in nvram).

Any idea?

not its obviously not enough, the bios you sent is not from the laptop its from the hp website. you need to use google sometimes and search in youtube university on how to extract bios dump from a laptop using cheap programmer.
like CH341A.

[Nopslide]

Okay, CH341A ordered. Coming tomorrow, I'll try to make it asap. Thanks for the feedback !

Here are the bin files extracted from chips on the motherboard. (near RAM was a XMC QH128AHIG chip and on the opposite side of the board (under) was a Winbond one. I dump both of them).

Hope that I haven't done any mistakes

[Nopslide]

Seems like the bin files and the archive were erased ?

[Nopslide]

Hi, can someone help me to find how to use the extracted bin files?

Hi, can someone help me to find how to use the extracted bin files?

The XMC QH128AHIG chip is your bios chip, your bios file is 16MB, has .bin or .rom extension, just compress it with Winrar or 7ZIP and post it here.

This is tools

Ok, I should praise this forum. You guys have been a huge help, writing the new bios was a success. I am eternally grateful!
