Can not hibernate…
This is nothing to do with that Java related hibernate technology, more about overlooking of simple thing 
Harddrive of my HP Pavilion laptop was crashed, totally broken, thus I’ve installed new hard drive, reinstall XP and all needed drivers, and about 2 hours it’s ready filled data from the backup.
What happenned then was when I was about to hibernate that laptop: the Stand-by button was grayed out. I thought it’s more to ACPI things, battery, and power management.
After about an hour found nothing, a friend told me about updating the graphic adapter drivers, “what ? what’s gfx adapter to do with hibernate ?” I laughed silently, but I did as I told, downloaded gfx driver from HP and installed, restart the laptop as it said.
… and to my surprise, Hibernate tab appeared in Power Options Properties.
I never experienced that problem before, and maybe there’s problem with gfx driver, but what I knew was do not laugh at any suggestions though how silly it seems at first.
