Found a weird fix for random laptop shutdowns on a Dell G5
I had this Dell G5 5590 in the shop last week that would just cut off after about 20 minutes, no blue screen, just dead. Customer said it was getting hot, so I repasted the CPU and GPU with Arctic MX-6, but it did the same thing. I was about to order a new motherboard. Then I checked the event viewer and saw a bunch of Kernel-Power 41 errors, which usually points to power. On a hunch, I pulled the battery and ran it on just the AC adapter for a full day. Zero shutdowns. Put the battery back in, and it died in half an hour. The battery was swelling just enough to mess with the system board when it heated up, but not enough to be super obvious. Replaced the battery for $90 and it's been solid for three days now. Has anyone else seen a failing battery cause hard shutdowns without any other signs on these models?
