We have a laptop that keeps shutting down and a a look at the event manager showed the following codes at roughly the same time the laptop was shutdown:
Error message: Error code: 0xDC, Sub error code: 0x7C

None of the solutions in this thread (a) updating BIOS or (b) downgrading from Windows 11 to 10 work for me. I don't want to downgrade

I highly doubt that Microsoft / Lenovo will collaborate & solve the issue.
Only forum members' solutions I have hopes for.
