Hi,
You can use standby, but not hibernate.Hibernate is the same as shutdown,
except the contents of ram are saved to the hiberfil.sys file on the hard
drive. The upper levels of standby (S1/S2 power states) are most suitable
for allowing scheduled tasks to run.
A definition of the various power states:
S0 - Up and running
S1 - Standby. Drives, display off. Power still on to cpu, fans, ram
S2 - Standby. Same as S1, but cpu is powered down
S3 - Standby. Power only to refresh ram
S4 - Hibernate. No power, contents of ram copied to hard drive before
powerdown (hiberfil.sys)
S5 - System off.
Not all states are supported on all systems, and this is a somewhat
simplified view. Some systems, hardware, or combinations thereof will not
support any of these states.
