So I was too busy to open the case, and do any of that... so I just sent it to Redington (the HP guys) to have it fixed. They didn't fix it, just replaced it, and charged me 400 Riyals. Thanks for the amazing advice guys, I should have come here first. Will go to Sofitel see if they can fix it, and if they do, I'll go to Redington and make sure someone's fired.
