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.

Has anyone dealt with a similar Surface firmware hang like this?
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.

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

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!

The word password has been edited out of the thread title now, so your post is ok here. How many seconds does it stay on the logo for, do you see a slight flicker after 1-2 seconds with the logo carrying on for a few seconds more

Does anybody know how I can recover a bad BIOS on a surface 1943?. What are the steps I need to do and does anyone have a UEFI/ BIOS file that I can flash.

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Cheers for the heads up on this, just one question, where can I get the UEFI/ BIOS file from to write it to the chip? Also where is the BIOS chip located and what is its markings?.

I am new to this particular make and model of device, and appreciate all the information I can get with regards to this.

Kind regards and thanks again

Austin.
