hi guys,
my previously solid macbook pro 09 version running 10.6.3 has been having intermittent sleep issues. I believe this is only happening at work. I have to use my computer in two different locations. Same wireless network in building (secure WEP). I shut down all programs , disconnect all usb stuff and external monitor and put to sleep by apple menu. When I go to wake up, I sometimes I see black screen with faint image of desktop. The computer at this point is unresponsive and requires restart. I tried running onyx and resetting PRAM, running disk warrior. I think this may be after last OS update. any ideas? Note this doesnt happen every time.
thanks in advance
