Windows 7: Event 41 Kernel-Power random crashes

05 May 2015   #21

Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

Tried it and it didn't really fix it. I'm starting to think this is hardware related. I did a google search and it looks like the random shutting down is a common problem for Acer laptops. Do you have any ideas how I could troubleshoot this? Or maybe I should re-install windows on a fresh drive before ruling out any potential windows/driver issues?

A reinstall would certainly rule out Windows. If you're happy to perform that then feel free, if you need any pointers or help just let us know.

I wonder how this ended... I have very similar error. I plan to post own thread in few hours as each Kernel-Power error may have different cause. However, looking forward to your update on this.

It seems the kernel error 41 is just the typical unexpected shutdown message... it can be literally anything.

In my case, every shutdown has the following log entry in the event viewer (just noticed it now):

ACPI thermal zone ACPI\ThermalZone\TZS1 has been enumerated.
_PSV = 0K
_TC1 = 0
_TC2 = 0
_TSP = 0ms
_AC0 = 0K
_AC1 = 0K
_AC2 = 0K
_AC3 = 0K
_AC4 = 0K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 369K
_HOT = 0K

It seems to be related to overheating... but this makes no sense for a laptop to overheat right after being turned off for a night. After turning on most temperatures are around 40-50C as well according to speedFan. I have had quite a few 80-90c temperatures in the past but only when playing games.
