Powers off after suspen to mem

If I suspend to memory, ie. echo -n "mem" > /sys/power/state, upon a resume (when I hit any key) my laptop just powers off, I see my X session and the it drops to console and turns off. I'm running a 2.6.15 kernel with acpi patch for 2.6.15. My system is an Acer aspire 1694wlmi, custom dsdt file.

Thanks,
Dan.
