If you go into the BIOS you'll probably find that you've got two options for
sleep. S1 and S3, if you select S3 the system will power everything down
other than your RAM.
To get hibernate back make sure Hybrid sleep is disabled (on non-mobile
machines it removes the option from the Start menu) and if that doesn't make
it show up run 'powercfg -h on' on an elevated command prompt.
Personally I'd recommend using the hybrid sleep and changing the sleep mode
in the BIOS to S3, that way the system will be almost entirely off (fans,
hard drives, CPU etc) yet be able to resume in 3 or 4 seconds.
And it'll still resume even if the power gets cut, because it saves the
contents of RAM to the hard drive too like hibernate.
