I’m using a Lenovo All-In-One running Windows 11. Version 24H2 (OS Build 26100.6584)
My issues started about 5 months ago, I have 2 months left on warranty.
The problem: Any time the machine is put into sleep mode for an hour or two it automatically reboots. Sometimes while I’m using it it will crash, and then reboot. Quite bothersome. I contacted Lenovo support, I was encouraged to reinstall the OS from the Lenovo help page. There were two possible OS reinstall options: the first suggestion was the Lenovo preferred choice. I did that and the results were terrible, apps wouldn’t work, the desk top was bizarre, the whole thing was a mess. I reinstalled from the Lenovo generic Windows 11 reinstall option, much better, it worked for a couple of hours. I ended up going directly to the Microsoft wage and getting their latest Windows 11 install package and this was much better, lasted about half a day.
What I see: On some crashed I simply get a reboot. On some I get all sorts of warned appear on a black screen saying that there was a major problem and I need to restart the machine myself. The MS help site suggest turning the auto-restart option off, I did that, no difference, still crashed. The last major crash I was offered the chance to do a total evaluation of the hardware using a Lenovo diagnostic package. Took about 7 hours and everything was test, all hardware was 100% functional, I took some photos of the results page with lots of long coded results. After that test I started the system again and in about an hour after putting it to sleep I once again saw the black screen telling me what I had seen before. This time I noted in very fine print the statement
Stop Code: SYSTEM_SERVICE_EXCEPTION (Ox38) `”What failed: ks.sys”
That’s my problem. Anyone have a clue what is going on and how to fix it??
