Problem waking up sleeping MBP

[AlmightyAlmich]

I have had my macbook pro for a while now and have had a reoccurring problem. When I am using it and close it without powering off or anything, it doesn't always wake back up when I open it. It typically happens if I leave it closed for an extended period of time (anything over 8 hours tends to do it). Does anyone else have this problem? It is infrequent enough to the point at which it hasn't really caused me any inconvenience, but now it just kinda bugs me.

I'm running 10.5.5 on an Intel mac if that helps

Thanks in advance for any advice

OMG!!!!

I have the exact same problem on my MacBook Pro!!! I have asked your same question 3 times on this site, but no one seems to have any ideas on how to fix it. And yes it doesn't happen a lot, but it happens enough to bug me too.
