Macbook Pro waking up when put to sleep

I still have not solved the problem ... new solutions?

UP!

Hi John,

I just noticed the same problem on my macbook pro (from Sept 2009). I'm pretty sure it's a software bug because everything seemed to work fine on a clean install of snow leopard on a wiped drive until I did the updates, but it seems weird that not many people have noticed it (searching on google doesn't turn up many results). Maybe it's not that noticeable unless you sleep your computer from the keyboard shortcut a lot since the problem is fixed for a while after restarting the computer.

I also noticed that using the keyboard shortcut again immediately after the computer wakes up from sleep after the first time will put my computer to sleep (and it will stay asleep). However, the screen stays on much longer than going to sleep from any other method. Using the other methods, the screen turns off almost immediately but the light takes a few seconds before it starts pulsing. Using the keyboard shortcut twice, the screen stays on for a few seconds after the command is given but the light starts pulsing almost immediately after the screen turns off. Does your computer do the same thing?

I haven't found the solution either. I also have a few friends who got macbook pros around the same time I did and I'll see if they have the same problem.

First of all, thanks for the answer! So, my MB Pro (October 2009) reacts in the same way! Up to version 10.6.4 the keyboard shortcut (cmd / alt / eject) worked great! Have not resolved with 10.6.8! A few days ago, I called the technician asked me to return the computer to perform new tests,

I'll will report shortly and I'll keep you updated! But I doubt that the technician can find a solution. It could be a problem hard drive, in fact, I remember that the technician had installed a new HD (with 10.6.7) and the problem occurred only rarely, and then try again repeatedly and insistently. However, it seems, for Apple isn't a defect, but rather is for us! I want a Mac running at 100%, we can not always wait 10.7! Besides, I'm not going to buy Lion now because I have some programs that are incompatible! I invite you to indicate the problem here: http://www.apple.com/feedback/macbookpro.html and hope to solve. Let me know if you have news! ...Sorry for my English!

I'm not sure that it's a hard drive problem. I have a solid state hard drive in my computer and I assume you have a regular one. I thought it might be a problem with the internal keyboard and touchpad USB connection, but it also doesn't seem likely since the second try using the keyboard shortcut consistently works and other keyboard-based ways to sleep the computer works as well as all the other keyboard shortcuts. If it is a hardware issue, I would guess something in the logic board needs to be fixed. I'm pretty sure it's a software issue (since everything works on a clean install before updates) so I'm not too concerned anymore. However, I'll be keeping very good back ups just in case. It might even be some weird interaction between preference settings and the programs on the computer. I didn't get apple care so I'd have to pay for any support from Apple, which I don't want to do unless I think it's a hardware issue. Although if I have to replace the logic board (which seems to cost around $1000), I'll probably just get a new computer. I already sent Apple an email using the feedback link.

I also can't find iCal helper on my computer which is weird since it seems like it would be bundled with iCal, which I have. I have iLife helper though. Haven't tried to mess with it yet and not sure I want to.
