Wake issues.

[Dellathane]

Just chipping in here.

My desktop doesn't wake up successfully unless there is less than 2GB of RAM (usually has 3). That can be removing a stick physically OR limiting the amount of memory via msconfig advanced settings. That requires a reboot though so it's a long way from a fix. I only discovered it because I play Medieval on limited RAM so I can get the higher resolutions.
Anyway point is it could be more of a software than hardware problem, but that's just a guess since I don't know what msconfig actually does to make the extra gig disappear.
