StandBy and Hibernate

What's the difference between putting your PC in Hibernate or Standby mode? Yeah, we weren't sure either. Luckily the Productivity Portfolio weblog schools us on the finer details of Windows XP power schemes.

Using Standby:

Your machine recovers quickly as your data is stored in RAM. The slower part is waking up the peripherals. Although your machine is in "standby" the power has been cut to items such as your hard drive and monitor. You're running your machine in a very low power mode, but it is still on. This mode can be useful if you're on a notebook and need to conserve your battery while you step away.

With Hibernate:

The big difference is that your PC has shut down and is not pulling power. Another difference is that your data is saved to your hard disk and not RAM. This makes it a safer, but slower option for shut down and resume.

Not all PCs have the capability and are configured to Hibernate. If yours is, to see the Hibernate option on your XP shutdown screen, hold down the Shift key when you shut down .
