Laptop shuts down after suspend to ram

I have a sony vaio laptop with an intel processor and nvidia 330m graphics card. I use linux just for kicks and as a small hobby so i don’t really know what i’m doing… but at any rate, when i put my computer to suspend to ram, it enters the suspension well with no apparent errors, but when i try to wake it up, it restarts the computer… its really quite annoying considering i use suspend a lot when i’m using windows where it works… at any rate, any help would be more than greatly appreciated.
Thanks

Have you tried chaning the shutdown/suspend method? I think it is in /etc/suspend.conf. Remember to backup the file before changing it!
