If you compare the locked and unlocked files at posts #43 and #44 you can do it yourself with a hex editor

TONGFANG "GM7TG7P" Bios Password Problem?

by traxformania

Hello,

I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

I'm trying to reset my bios without success.

I tried :

HP Omen 15-dh0052nf power-on & bios password

by 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....

I need a BIOS dump for the Samsung S49CG934SU monitor

by Habble7

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Troubleshooting Attempts:
