MPB wouldn't wake up

Hi,

I have a MBP bought last August. I found that after I closed my MBP to put it into sleep and open the top, the MBP just wouldn't wake up to the login dialog. I have used the hardware diagnosis application to verify whether the memory goes wrong, the result is negative. And I tried to turned off the bluetooth every time before I close my MBP, buy the problem hanging still. I don't how to solve it, could anyone help? Thx.

Welcome to the Forum. What OS are you on and is it up to date.

Have you tried resetting the PRAM?

Resetting your Mac's PRAM and NVRAM

Also, it could be the logic board, though if you ran the Apple Hardware Test, and nothing came up relating to that, it might be a problem that only a certified Apple tech could diagnose (such as at an Apple store). This is a brand new MacBook Pro, running the latest version of Mac OS X?

Hi, guys, thx for the reply. My spec is:

MacBook Pro
MacBookPro5,2
Intel Core 2 Duo 2.8 GHz
Memory: 4 GB
OS: 10.6.3

Hi,

I might find the solution: Apple Support, About Reseting the SMC. I hope it helps.
