Legion Go Crashing After Plugging In Charger

It started happening a few days after I bought it secondhand when I tried getting Cyberpunk2077 to stop crashing several times. It didn't affect any other game until almost a week ago. It basically only happens when I launch a game past its launcher or when I turn on the Legion Go on after a while, but it doesn't happen idle when using non gaming apps. I had just finished installing 24h2 a few minutes ago since I was on 25h2 and the issue literally occurred again right after it booted into windows when I plugged in the charger a few seconds prior. I've *attempted* to reflash 40ww and even edited the config file so it didn't need the charger in, though I can't really be sure that it finished since I went back to factory settings before I did. It runs just fine on the battery as well. Reinstalling windows with "keep files" on didn't fix it when I tried a while ago either. I'm just bummed out cuz I've seen other ppl have the same problem and literally nothing has worked for me, and I don't want to believe the motherboard was damaged :/
