Ensure you have installed the video drivers for the EPIA, the hibernation options disappear if the system uses the default drivers.
I recently did a reformat on my via 800 and reinstalled xp home. Before i had it so that my computer would go into standby or hibernate when the power button was pressed. Now the option has dissappeared altogether. I went into power options and there wasnt even a hibernate tab there. I figured it was a bios issue but i didnt find anything to enable it. Can you guys give me some pointers as to how to enable it.
ah thats probably my problem. I dont think i reinstalled the 4-in-1
I had the same problem :-)
