Acer :: Anyone Have 1410 With Hibernation

I have a Gateway EC1803h which as far as I can tell is identical to the Acer 1410 except for the design of the case, so I'd like to ask this to the Acer users since there are many more with the 1410 than the Gateway.

I'm running Windows Vista. I've disabled the ACPI Lid driver by changing the driver to "Volume Manager" as suggested by various internet sources for fixing the problem where closing the lid, even with the close lid action set to "do nothing" can cause the lcd to not turn on again when opening the lid.

So the problem is with hibernation. If I hibernate the machine, then resume again within let's say a minute or so, it comes back up fine. If I hibernate, then wait a longer amount of time, say 10 minutes, I can see the BIOS boot, the "Resuming Windows" splash screen, but then when I'd expect to see the login screen, instead the laptop screen turns off, and I see nothing. Oddly enough, at this point, if I plug in an external monitor, I can see the login screen there, so the OS is running properly. I can even log in. But at this point, I cannot Fn+F5 to enable the laptop screen. It's like the laptop screen has been disconnected/disabled/removed, whatever you want to call it.

Another weird symptom is that at this point, I can usually see a "System" process that ends up taking up 100% of the CPU processing, all of the time (not just spikes), so the task manager basically stays at 100%.

This feels like a software/driver issue to me, but I've been unable to find any other Acer 1410 or Gateway EC1803h users who've experienced this. I've tried the video drivers on the Gateway site, Acer site, as well as drivers from the Intel site. Same behaviour. I'm contemplating exchanging it for another unit, but only if there's a chance this is indeed a hardware malfunction.
