Black screen exiting Sleep Mode

[Cancelliere]

Hi folks,

I just have my mid 2010 MBP logic board replaced for this issue. I'm quite satisfied about the result as my MPB doesn't randomly freezes anymore, but a small issue is still present; if I lift up the lid, after a few seconds the screen turns black and I have to press F1 or F2 keys to make image goes back. I mean, it's a really small issue but I haven't yet figured it how to solve it. Is there someone who can help me?

@Cancelliere:

Have you the newest firmware (EFI) and Mac OS X updates? If yes, then it is probably a PRAM or SMC problem.

 

[Cancelliere]

Yes, all updates are installed. Are SMC and PRAM problems bad things? Could I solve myself?

By the way, nice piece of hardware you got!

 

[Mr. Retrofire]

Are SMC and PRAM problems bad things?

Depends on the problem.

Could I solve myself?

But this no guarantee.

No worries, thank you so much anyway!

I have just reset PRAM and SMC and so far, knock on wood, everything is doing fine.
