Which makes me think that there might be some processes going on in the background, which takes up enough CPU cycles to make the system believe that its not idle. Which, in turn, would not let standby or hibernate to kick in.


Some progress. I have noticed that if I set the standby time to 1 or 3 minutes, the laptop suspends automatically. But not exactly after these many minutes, for 1 min option, it goes into standby after around 2 minutes, and for 3 min option, it takes around 5~6 minutes to start to go into standby mode.

Also, hibernation seems to be working (partly). I have set the laptop to hibernate after 4 hours. It went into standby mode last night and this morning when I switched it on and it started to resume. It seemed to have hibernated sucessfully. However, it is taking forever to resume! Its been something like 15 minutes now and after the reboot and Windows is Resuming message, the screen is just black with an hour glass cursor in the middle (which I can move with the mouse though).

Also, are the stanbdy and hibernation actions logged to the event viewer? Anyway to know when exactly laptop started to go into standby and hibernate mode?
