I have a Lenovo G530 laptop, currently running Fedora 13 (64 bit). When I try to suspend to RAM, the machine just shuts down. I can restart it and have it run just fine, but I cannot get it to resume. I had the same problem with Ubuntu after upgrading to Lucid; I decided to give Fedora a try and found no change with this problem.
I've tried suspending from the shell, but the same thing happens. I use the following command (as root):
echo mem > /sys/power/state
Has anyone else had this problem?
