This is a major issue with Vista. My Asus R2Hv wakes up in the middle of the night even with the hold key pressed. To me that’s a security hazard. Apart from the risk of the machine melting itself and all my work – It could turn into a fire. Totally unacceptable!

Microsoft has a PowerPoint presentation with lots of details on Sleep in Vista at:

They claim that the situation has improved on Vista, though many of us seem to have a different experience.

I don’t use hibernate at all, have it disabled. The Vista Task Scheduler can indeed wake up the PC but I checked all scheduled tasks and they are all configured to not fire up if on battery power. I suspect that something fired up anyway.

I have it on good authority (Josh Einstein to be precise) that it is possible for the OS to wake the computer from standby, as it does when a PC goes from standby to hibernate on its own. Typically, this is done for power saving purposes. However, if your page file is fragmented, the computer cannot hibernate. Instead, it will wake from standby and stay on. I discovered last week that my page file was fragged, which was preventing my tablet from hibernating. If your PC is set to hibernate after being in standby for a certain period of time, but it stays on instead, defrag the hard drive.

James, I don’t know what “sleep” is. Well, *I* know, but Windows doesn’t. It only has Standby and Hibernate modes. Stop using standby and use hibernate instead. This shuts the power off completely. Only the power switch will turn the machine on after that. At least that’s how notebook computers work, no promises om the UMPCs.

This happens to me too often. I would say that it starts up every 2 out of 5 standsby. I am facing also another problem with Standby mode: many times when I trun back on my Q1 I find it had shutted down all alone!! Any hint??

It seems I remember with the first generation of tablets that there was an issue with hibernation that would cause my TC1000 to waken when it tried to go from stand by to hibernate. I wonder if this is related somehow?

Mine are set to Hibernate after they’ve been in Stand By for thirty or sixty minutes (depending on how I set it for what my day looks like), and that has saved my battery some juice, but to do hibernate, it turns itself on for that purpose, that is, to copy the entire chipset memory to the disk, which takes about a minute.

I don’t think my Q1 has failed to hibernate properly, but I think in sliding it back into the neoprene case one time I must have neglected to slide the hold key and turned it on from either hibernate or stand by. When I pulled it out, it was hot to the touch, and the touch screen unit was fried. If I hadn’t have invested in the Samsung keyboard, I wouldn’t have known if anything else was fried, or just that (just the touch screen unit). About a ten day/two week repair under warranty.

And since it’s open season for spammers today at jkontherun, I’d like to make available–darn, I’ve got nothing to sell. Never mind.

James, by default a new task IS set up to not wake up a computer if only a battery power. But the option is there, which is why I suggested to investigate which task is firing and if possible, uncheck that option to allow resume on battery power.

Mickey, I always make sure that the P1610 completely enters sleep mode. That is one step I NEVER overlook because of the potential danger of this situation.
