Sounds like a warranty issue, and if the unit's out of warranty, probably time to be looking for a new laptop. Which is about as much help as you're going to get on these forums, as you mentioned that you are engaged in piracy. Something that is against the rules to discuss on this forum.
HP Pavilion p6711f, windows 7 64 bit.
Here's the thing, it doesn't shut down on it's own, I don't think. The picture goes off and it's unresponsive, but the power light and HDD indicator light are still on. Like it goes to sleep, but won't wake up. That's the only way to describe it. No new programs, no internet porn, virus and malware scans are clean. Microsoft Security Suite btw. I do download a lot of music and movies and tv shows, I'll be honest here, piracy. Been doing it for years and never had this happen. Thoughts? It's just a pain in the butt. Oh, and to get the PC to come back on, I hold the power button down til it goes off, then I turn it back on.
