Surface Laptop 7 for Business continues to suffer from spontaneous reboots after coming back from Microsoft service

Tad 20

My Surface Laptop 7 for Business has been spontaneously rebooting ever since I purchased it new from Microsoft for over $2500 in December 2025. It will appear to function normally for hours or sometimes days but experiences literally random, spontaneous restarts almost daily.

The logged System error is always Kernel-Power ID 41, Task Category 63. It does not matter whether I am docked, or using the laptop without any accessories attached, with or without battery power. I ensured that all of the Windows updates were applied. I tried MANY recommend power settings including turning off advance power options like PCI express and Link State Power Management. I ran the DISM and SFC command prompt tools recommended by Microsoft Support.

Last month I finally sent it to Microsoft for service. I wiped clean as instructed before sending it in. The exact same laptop was returned to me this month. There was no explanation of what Microsoft service did (if anything) other than run a stock set of tests. There was no response to the detailed explanation of the issue that I provided in advance and with the service return.

Unfortunately, this laptop continues to spontaneously reboot. I cannot understate how awful this is. I have a tech background and an Surface Laptop 3 that has worked flawlessly for years, so it is not like I don't know what I am doing.

What do I need to do to get this laptop repaired or replace permanently?

You've done everything reasonable. Further DISM/SFC/driver cycles are a waste of your time on what is almost certainly a hardware fault.

It strongly suggests either an intermittent hardware fault (motherboard, power management circuitry, memory, SSD, etc.) or a firmware issue that Microsoft's standard diagnostics did not reproduce. Event ID 41 itself only tells Windows that power was lost unexpectedly—it does not identify the root cause.

When you contact Microsoft support again, be explicit: this is your second contact for the same unresolved fault on a device purchased new in December 2025. You want a replacement unit, not another service depot cycle.

Microsoft sent me what at least appears to be a new unit about a month ago and so far, so good. ... I followed your advice, making it clear (in the online return explanation and in a printed letter with the unit) that it was the second return of the same unit with a hardware fault that their diagnostics did not reproduce the first time.
