i set sleep mode to 30 mins. After, the monitor turns off but the machine is still on. Also, when i press any button, move the mouse, or press the power button, it seems as though the computer froze! It wont respond!
Or some other driver thats stopping it from sleeping. I had a wireless card that would stop my laptop from entering sleep mode. I would have updated it but there was only the one driver. It was a junk Dlink card so I just tossed it and bought a new one. Try bios and chipset drivers, but it could be anything.
