Anyone experience issue with waking up the latest MBP from sleep? It happened twice to mine recently. I close the lid as usual to put it to sleep. After a couple of hours when I open the lid, the screen is blank (as if it's not swithed on) but I can feel the hard disk is still spinning quietly.

No, I didn't. Everthing is as it is. MBP 13.3, 3 months old.

Using Mac OS mate. I have tried googling for answers, most of them suggested using Terminal to tweak the sleep mode settings. Something along the line of switching the default sleep mode of #3 to #0. But the main issue here is I'd like to know what cause this happen?

Guys, I'm having a 'no entry' sign everytime I boot up my MBP but when I can go to safe mode, restart and it will be back to normal. It's just that once I shut it down, the problem will come up again when I want to boot up. I ran Apple Hardware Test with the applications CD and found nothing wrong. I even verified my Macintosh HD, repaired disk, verified permissions and repaired permissions.

Additionally, I have tried the method of resetting PVRAM by pressing Command + Option + P + R during boot up but to no avail!

I think I have exhausted almost all the options available. Does that mean I must do a clean reinstallation of my Mac OS now?

I'm currently on 10.6.2, which is upgraded using the SL upgrade CD.
