"Purchased an HP laptop with an extended warranty. 13 months later having a problem with system overheating and shutting down. CompUSA says they can't find a problem and won't repair it. I will be sending this in to HP for repair at my own expense and then going after HP for fraud. Very convenient that they can't find a problem. They replaced the hard disk which worked perfectly - though I had backed up my data - will take days to reinstall my apps."
