Oh, hey. I decided to re-look into this (it's 1:03am now! LOL) and found the old fashioned sfc /scannow showed no integrity violations. But the powercfg -a command showed that the vgapnp.sys display driver is not supporting standby in neither S1, S2, nor S3 sleep states.
Is there an alternative display driver? (I didn't see anything available at AcerEurope and I'm not sure who to trust when poking around cyberspace for drivers! LOL)
Thank you very much!
PS Why would this fresh Win 7 32 install (this time) decide not to enable sleep mode the same way it had earlier this year? I wonder if I tried another reinstall if it would resolve itself? My other forum topic, PinchedHDSpace, shows a D partition with what I believe amounts to a crash report with a bunch of files and a folder labeled, "0f15e61f8b9a14dbc1ef1807fca73679". Also, when I restart, there are 2 win 7 choices. (Normally restarting doesn't hang up on reboot asking which Win7 (or Win7) to boot)
