    I used to be able to close the lid and the MBP would fall asleep. Now it only works rarely or I have to use the power button, press sleep, and then close the lid. It doesn't matter if Airport is on or off, if there's no ethernet cable, or if there's no power plugged in. I haven't installed anything recently, so I have no idea what's going on.

    I've seen an increase in this problem myself. I have Parallels installed but haven't used in it many weeks. I suspect 10.4.8, but i could be wrong. It just recently started happening to me. Irksome.

    This has been happening to me lately also on my MBP (CD). It started soon after I upgraded to 10.4.8. I am a parallels users also.

    I find that if I reset the parameter RAM it solves the problem for about a day (which is about 3-5 sleep cycles for me).

    But then it goes back to not sleeping when I close the lid.

    I took it to the apple store, and they recommended replacing the top of the case and the sleep sensor. The parts are in, but I'm waiting for my new C2D MBP to come in before I can give this one in for the repair.

    I'll post the results on this thread after they replace those pieces. Personally, I'm skeptical about a hardware solution. I think it's a software issue myself. But I could be wrong.

    I noticed a small difference in the sleep cycle of my MacBook Pro when I upgraded to 10.4.8. When I close the display, the Apple logo stays illuminated for several seconds most of the time, whereas before it would kill the backlight immediately while it was initializing the sleep cycle.

    I haven't had problems with my MBP not going to sleep at all. I have a Core Duo.

    Curious. It seems like it's also getting hotter now. I hear the fan kicking in more often (and the weather is COLDER here) and sleep is still a problem. Normally I don't mind the MBP on my lap, but now it's getting ridiculously hot.

    I don't have Parallels installed and having issues. :(

    Any idea how long an Apple repair at a store would take (if it's possible to do in store)? This is my college laptop where I do all of my work. It might be slightly difficult to get through a week or two of school without it. Thanks.

    Looks like there's a thread going on in the Apple Support pages. All fingers point the 10.4.8. :(

    I had the same problem with mine and the geniuses at the apple store said it was the logic board. it is in for repairs right now. I will let you know what they find out.

    yeah my macbook pro does that 1/3 of the time i close it.
    both in windows and mac osx.

    just a minor setback, sometimes ill quickly go to work and close my book and it'll not sleep, i bring it out to use it and the battery is drained.

    sometimes it sucks cuz ill forget my adapter at home, need to purchase another one lol...

    other than that, and a few small things, this thing is dope.

    After I installed bootcamp, and windows XP on my mac and set it up, I started noticing this problem.

    To fix it I checked the power management in windows XP and noticed that I had set the computer to never go to "standby". After changing this back to some amount of time (I chose 5 hours, because for some reason when in windows, and the laptop goes to sleep on time out, it locks up) the sleep problem disappeared.

    So, make sure, in windows through boot camp, or parallels, that you check if your power management control pannel item has standby at least "on" 5 hours is the longest it offers.

    I hope this helps you guys.
