I've had this issue for about a year and a half and couldn't get Apple to fix it while I still had AppleCare. I have a 4 year old mid-2009 MBP. 2.26 ghz core duo with 2 GB RAM running OS X 10.6.8. The hard drive is 160 GB and was replaced just last year. Still HDD. The problem is that often when I put the machine to sleep either by closing the lid or selecting from the apple menu, the screen will not turn on when I try to wake it up. The sleep light will turn off, and the drive will start spinning, but no amount of mouse clicks or button presses will get it to respond without a hard restart. The only thing I ever got Apple to do was fix the planet or folder and ? of death on startup which probably resulted from the hard restarts. They replaced a couple of hard drive cables and the hard drive. Can't remember if they did the logic board as well. And yet it still continues to not wake properly. I've disabled safe sleep and gone to the "old" sleep mode 0 of the PowerBook era which seemed to fix it for short sleep periods but not for longer periods that involve travel. I've reset the smc or whatever but not the pram. I haven't felt comfortable doing that yet. I keep wondering of it has something to do with my magsafe that has gotten progressively worse over the last year. Getting it to connect and actually charge is a challenge anymore. It hasn't frayed yet, so I'm not sure of it's part of that recall. Anyway, I've read tons of forums and Apple support pages that don't seem to offer a long term fix for the not waking issue. I can't continue just working around it during my senior year of college, and I'd rather not drop $1000 USD or more to get a replacement, although I've seriously considered it. Any suggestions? Please and thank you!
