17" MBP - no screen ilumination when resuming from sleep

i've had bug since installing latest lion update 10.7.3

never shut down 17" mbp, close lid , let sleep, however, since latest lion update when open lip screen illumination comes on briefly , turns off - hit 1 of screen brightness buttons (f1 & f2) , screen illumination comes on.

how go correcting ?


ps. sorry if has been posted - search didn't come anything.

 

the same problem reported on apple forum, no solution.

i've been looking answers, since upgrading lion, problem more of nusance, when close lid on macbook pro (15" 2.66 i7, 8gb ram) , goes sleep mode, when reopen screen screen backlight comes momentarily, goes black (screen image there, no backlighting) nothing gets come out (reclose/open, clicking trackpad, keys, etc.) except f1 key. pushing f1 "wakes" backlighting, hit f2 brighten up, don't have further issues until close again. granted not big of deal given issues else having this, still nusance fix. don't know if work you, it's been working me.

i've read reseting power controls resolve bug, not sure how perform reset.
