Am having the same problem - I can wake it by pressing Ctl-Alt-Del - the screens wakes up and I cancel the Task Manager. If I hit the power button the machine turns off. The other keys are active but do nothing. C-A-D works everytime. No password on wakeup. ALL power settings are at "Never". It's not supposed to sleep at all! I have a 2 yr old Toshiba Laptop Qosmio AV-412 with 500GB HD, W7 Ver 6.1 Build 7600, just found MSINFO is not a recognized command -
Also - have a complaint about W7 - when expanding/collapsing folders it pops the cursor back to where I was previouslt instaed of keeping me near the folder I was working. Very irritating.
