Hi.
I'm dealing with a persistent boot issue on a Surface Laptop Go (Model 1943) after a motherboard replacement.
The original motherboard was burn to a crisp (CPU power rail burn a hole in the motherboard); so I got myselft a replacement but din't manage to get it working yet.
Situation:- Original SSD was BitLocker-encrypted.
- Motherboard was replaced with a (supposedly) known-good donor board.
- Device powers on, shows Windows logo, but gets stuck — no spinning dots, no activity.
- Cannot enter UEFI (Volume Up + Power does nothing).
- Cannot boot from USB (Volume Down + Power also hangs).
- Without an SSD present, the board doesn’t power on (normal for Surface?).
What I’ve tried:- Swapped in a brand-new blank SSD → same result.
- Wiped original SSD externally → same result.
- Created official Surface Recovery USB → no boot.
- Flashed BIOS from (unknown) donor board → no change.
- Swapped BIOS chip from the original board → still stuck.
- Tried multiple UEFI/boot key combos.
Cloud this be a ME firmware mismatch or missing?
Could the original BIOS be corrupted or have missing contents?
Attached I'm sending the BIOS dump from the new motherboard. If anyone could have a look at it and a possible fix that would be much appreciated.

Hi, just to clarify — I didn’t actually ask for a BIOS password removal. My request was something completely different, which is why I created a new topic. I’m asking for a BIOS integrity check on a donor board, not for password removal. Thanks!Comment

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
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 :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -

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.... -

1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...01-14-2024, 06:35 AM
