Whats the difference between “system standby,” “hibernate,” “monitor power management,” and “turn off hard disks”?
There are four basic types of computer power management, or “sleep” features on Windows PCs: • “System standby” • Drops monitor and computer power use down to 1–3 watts each • Wakes up in seconds • Saves $25–75 per PC annually • “System hibernates” • Drops monitor and computer power use down to 1–3 watts each • Wakes up in 20+ seconds • Saves work in the event of power loss • Saves $25–75 per PC annually • “Turn off monitor” • Drops monitor power use down to 1–3 W • Wakes in seconds or less • Saves half as much as system standby or hibernate: about $10–40 • “Turn off hard disks” • Saves very little energy
