I don’t want to turn of an hp laptop with1gb memory hooked up to an ac adapter, since it has no hard drive and must run from a live CD, and i already have the configuration I want (in case you’re wondering, it’s Linux Mint Daryna). But I don’t know if overheating would be cause for alarm. I’m not talking about a few hours. I’m talking about a few days (maybe tonight, tomorrow, tomorrow night, and maybe the next day). But if it’s a bad idea to even leave it running overnight, then I kind of don’t want to to do that.
