I have a new Acer Aspire with an Intel i5-8250U CPU and it works completely fine but for some reason when the battery's running low and I plug it in, the fans run wild and it starts heating up pretty quickly. When it's not in use however it is completely still and cools off again.This has happened a handful of times and sometimes it even freezes completely and I have to turn it off. I don't have much experience but I checked the CPU speed and up to 90% of it was in use and it was running pretty fast even though I had only one task open. I couldn't find anything similar on the internet so I appreciate your help.
