Last year my sis gave me her old Laptop (omnibook 6000) and I thought YAY! Didn't use it until now and it turns out the thing only runs when plugged into the mains. It also gets really really hot. Like burn your dick off hot. This is a new issue as it worked fine when I first got it. There's also constant pauses when running the thing. Like its struggling to handle all the information.... And I'm not even running any prgrams on it! Any help?
