I'm having a strange problem that just started today.

 

I close my macbook pro lid and put it asleep. Then when I open the lid the keyboard lights up. The screen comes on for about three seconds and everyone looks fine then the screen goes to sleep again. If I close the lid and open it again it comes on for 3 seconds and goes to sleep again.

 

Occasionally I can get it to stay on hitting Function and brightness keys. But just as often it takes a hard reset to get things working again. But then if I close the lid and open it the problem starts again.

 

Any idea?

 

I'm running the lastest Lion update.


Macbook PRO 15, Mac OS X (10.7)
