Hi guys,
I want to enable hibernation on my desktop, only to find there is not HIBERNATE tab on the power option. Is there any other way of enabling hibernation?

Windows xp, I cloned the system from ROCK motherboard

Do you have the advanced power management features enabled in the BIOS?

When you power up he computer, you need to hit the correct key on the keyboard to go into to BIOS config. It's usually the DEL, F2, or F11 key. Look for the power management options. Make sure it's enabled.
