Some linux help plz

[Neuge]

I dual boot my laptop with XP and SUSE 10.1 x86_64. I haven't used the linux partition much since I've had it, but I'm going on a 2 week trip soon and am going to need it to get some work done while I'm gone.

The problem is that none of the powersave features work properly. Suspend to disk seems to work fine, but neither suspend to RAM nor standby work. The ACPI events (eg. lid close) always freeze the system no matter what setting I'm using (s2disk, s2ram...) and I have to manually shut down. But the most annoying part is that plugging in or unplugging to/from AC power always freezes the system. It runs fine on either battery or AC as long as it's booted that way, but I can't switch without first shutting down, (un)plugging, and rebooting.

I've looked everywhere for a solution but have came up empty. It's a Dell Inspiron 640m if that helps.
