Difference between standby Sleep and Hibernate (back to computer page)

Standby puts your computer into energy-saving mode, where it uses very little power.

Hibernate saves your workspace (all your open windows), then turns the computer off.

The difference is that hibernate saves more energy because the computer goes off completely, but it takes longer for the computer to wake up from hibernation, so it's not as convenient.

Standby
Hibernate

Energy Use
1-6 watts
0 watts

Time to sleep/wake up
a few seconds
30 secs. to 3 minutes

Sleep is more complicated, because it means different things on different computers.

  • Mac OS, desktop. Sleep is the same as Standby. There is no built-in way to Hibernate.
  • Mac OS, laptop. Sleep initially means Standby, but if the battery level drops very low then the laptop automatically Hibernates.
  • Windows Vista. Sleep initially means Standby, but it switches to Hibernate if the battery level drops too low (laptop) or the computer has been sleeping for more than three hours (both desktops & laptops).
