XPS 15 9500 Randomly Shutting Off
My Dell XPS 15 9500 keeps randomly shutting off. The laptop is three years old, and this issue started a few months ago. In the beginning, it would happen once a week, but now it happens about 20 times a day and it will get stuck in a loop for about six cycles before finally powering on and lasting up to 30 minutes before another random shutdown occurs. It happens on battery and on AC power.
I have scoured the internet for answers to this issue, and there doesn't seem to be a clear solution. I have updated my BIOS, disabled C-State, disabled TurboStart, and yet the issue persists. I'm hoping somebody has new information on this issue.
When I go into the event log in the BIOS, it shows the shutdown as "ASF2 force off" happening every few seconds.
Your help would be greatly appreciated, as this issue has made it impossible to work on this laptop (I was lucky it stayed on long enough to type this post). Thanks!

@ejn63 Yes the computer stays on just fine on the diagnostics screen. No shutdowns occur.
As painful as it can be, I would seriously consider a complete reinstall of Windows from the ground up. Particularly if the installation of Windows is now three or so years old, you likely have either conflicting settings somewhere, or remnants of old drivers or programs that need a fresh start.
Okay so I have been facing this for over 6 months now. Being a college student and working on different projects myself, the battery life on Dell XPS 15 9500 is not the best. I bought this laptop in 2020. So every year I make sure to open and clean the fans and take off dirt. After having this issue of shutdown, I opened it back up and this time I disconnected the battery and plugged it. This made sure my c ports were not bad. Then I opened the copper heat sink and it was filthy. I always cleaned the fan, but never actually opened the heat sink because I didn't have thermal paste. This time I made sure I had it and after cleaning it with isopropyl alcohol and applying new paste. Everything runs smooth now. The paste from 2 years apparently made it completely dry with regular use during the semester. Regardless, I believe that the lack of cleanness in heat sink combined with dried thermal paste was causing the computer to think its over heating and was causing it to randomly shutdown and not charge while it was on. Hope this helps!!

This forum page may help. That force off could be caused by a power loss of some type. Try checking the battery contacts and it may be that the CMOS battery is getting weak. Run diagnostics, F12 immediately at boot, and watch for any errors. Also it may be worth it to replace the CMOS battery.
