Humm didn't seem to fix it. I updated the kernel to CURRENT and powered down and waited for it to happen. I waited 15 minutes and nothing happen. I booted up, did some work, then shutdown, put it in my bag and headed off to class. When I got to class I opened my bag and found it had powered on. I'm thinking that it might take longer than I'd suspected, or have something to do with changing to and from AC power. I'll post more if I figure something out. andrew Justin Ma wrote: > > Have you updated your kernel sources recently?
