[Problem] Surface Pro 7+ BIOS seems to be faulty

BIOS/UEFI Modding BIOS Modding Guides and Problems

Hello. Thank you in advance for your helps.

I applied recovery to my Surface Pro 7+. After that I started having problems.

Problem 1- The Surface Pro 7+ doesn’t actually shut down. When I click Shut Down, the screen turns off, but the fans continue to run, and the light on USB Hub stays on until the battery is completely drained.

I tried Shift Shut Down, but it didn’t work.

I disabled the Fast Startup option in Control Panel, but it didn’t work.

I can only shut down by force shutdown (holding the power button for about 20 seconds).

Problem 2- There are three firmwares with yellow triangles in Device Manager. Surface ME, Surface System Aggregator, and Surface UEFI. I believe the problems are related to these. All three have the error “This device cannot start. (Code 10)” in the properties tab.

I tried roll back driver, disable and uninstall device options but it did not solve the problem.

I noticed this: The current UEFI version appears to be 30.102.143. But my Pro7+ seems stuck at 18.200.143. I’m not very experienced in these subject. As far as I understand, the device can not update its firmware. Is there a method like a forced firmware update?

From my UEFI info:

System UEFI: 18.200.143

Nuvoton dTPM: 7.2.2.0

Tcon Firmware: 160.146.4.0

SMF Controller: 58.0.2.31

SAM Controller: 14.102.139

Intel Management Engine: 15.0.1879.1

PD Controller: 14.1.0

Touch Firmware: 5.0.141.139

Thank you for your helps.

Welcome to the Win-Raid Forum!
Since I own myself a Surface Pro7 and had severe troubles with this device 2 years ago, I do not recommend to try the repair of your device yourself. Instead of risking a total brick of your laptop you should better contact a Surface Authorized Service Provider of your Country (>here< is the link to the related US site).
Please keep in mind, that Microsoft’s Driver and Firmware Support for your device will end on October 14, 2025 (look >here<).
Good luck!

Hello. Thank you for your reply. Unfortunately, I don’t have a service center I can contact.

This device is something I’ve given up on. I’d like to give it a try. Is there a resource on how to manually update the firmware for this model?

You can get the matching BIOS for a manual installation >here<.

Thank you. I already tried the msi file at the link, but unfortunately the uefi firmware does not update.

I recommend to download and run the MS Surface App and/or >this< Toolkit.

Thank you @Fernando In a few hours I will use both of them.
