Understanding Standby and Hibernation

Standby and Hibernation are energy-saving features that conserve power and reduce startup time. In general, Hibernation shuts down most notebook functions, while Standby simply reduces notebook activity. Standby uses more power than Hibernation, but you can resume more quickly from Standby.

■Standby reduces power to system components that are not in use. When Standby is initiated, your work is saved in random access memory (RAM) and the screen is cleared. When you resume from Standby, your work returns to the screen where you left off.

■Hibernation saves system memory to the hard drive, takes a snapshot of the notebook image, and shuts down the notebook. When you resume from Hibernation, your work returns to the screen exactly as you left it.

When possible, save your work before initiating Hibernation to prevent loss of data. Do not change the notebook configuration during Hibernation.

ÄCAUTION: If the configuration of the notebook system is changed during Hibernation, resumption from Hibernation may not be possible. When the notebook is in Hibernation:

■Do not add or remove memory modules.

■Do not connect or disconnect external devices.

■Do not insert or remove CDs or DVDs.

■Do not insert or remove a CardBus PC Card.
