I have a MacBook Pro 15 inch mid 2010 i7. I am on lion and I am having some problems with my mac. When I close the lid and later lift it again (note: I sometimes lift it instantly just to test it or after a couple ours.) I see the screen everything works for about 5 seconds when the screen just fades to black. To fix this I just turn down the brightness 1 bar and turn it back up. After turning it down 1 bar the screen instantly comes back up. If I dont do this I click my mouse my trackpad nothing responds only until I click the brightness keys down or up (if it was set to the max brightness already.) Please help as this is really annoying to change my brightness after every time I close my labtop. Thanks!
