I am posting here in the hope that someone could help me find the right direction to solve the following problem with my Dell Dimension (model 4700, runs XP Home). It used to be a minor problem but is becoming much more annoying as I want to use this PC in unattented mode.
The problem is the following : I am using a lot the XP hibernation feature, only rebooting when necessary. Putting the PC in hibernation works fine, waking it also, except the wake up part is behaving strangely :
After wake up (using the on/off switch), XP resumes normally, but goes into hibernation again after 2 minutes or so if I don't do anything with it. On the contrary, if I perform some minimal activities after the waking up like launching an application then the PC won't automatically go into hibernation again.
I have managed to far to live with this, until recently when I wanted to have my PC start during the day and record something from the attached DVB-T tuner (Terratec). The Terratec software is perfectly capable of waking the PC from hibernation, but when in unattented mode, the hibernation kicks in after a few minutes... The only way to perform unattented recordings is to leave my PC on all the time. Not very energy saving friendly...
I have looked so far in the Microsoft KB, tried to find something in Dell's one (much more difficult), to no avail. I have tried different settings for the internal ethernet card, which is sometimes responsible for problems with the hibernation process. No result so far.
Has someone encountered the same behaviour or know a solution for this ?
Many thanx !
