Of late - since maybe about 2 weeks back - my laptop just refuses to enter standby and hibernation. I have set my PC's Power Options to send it to one of these power saving modes depending on how long the machine has been sitting idle.
Toshiba Satellite A105-S4211
Win XP - SP3
1.49 GB RAM
hiberfil.sys file size = 1.49 GB (1,600,180,224 bytes). Size on Disk also shows same size. (Never quite been able to figure out why 'Size' and 'Size on Disk' are two separate parameters which tend to have different values most of the time. That said, it's not my main concern at this time.)
Free Disk Space: 3,865MB :: Disk space required to hibernate: 1,526MB
It looks to me like some process is resetting the idle timeout before the machine is due to enter hibernation. How do I find out which process that is?
EDIT: The machine does enter these modes if I FORCE it to do this, but doesn't happen via the auto-timeout Power Options. Forced Hibernation also takes longer than usual - at least 5-7 mins compared to the earlier 1-2 mins.
