Power management

To reduce power consumption, the computer has three power management modes: screen blank, sleep (standby in Windows XP), and hibernation.

To put the computer into screen blank mode, do as follows:

1.Press Fn+F3. A panel for selecting a power plan (in Windows XP, power scheme) appears.

2.Select Power off display (keep current power plan) (in Windows XP, keep current power scheme).

You can also put the computer into screen blank mode, press ThinkVantage button and use the ThinkVantage Productivity Center.

Note: If the computer is a Windows 7 model, it does not support ThinkVantage Productivity Center.

To end screen blank mode and resume normal operation, press any key.

Sleep (Standby) mode

When the computer enters sleep (standby) mode, the following events occur in addition to what occurs in screen blank mode:

vThe LCD is powered off.

vThe hard disk drive or the solid state drive is powered off.

vThe CPU stops.

To enter sleep (standby) mode, press Fn+F4.

Note: You can change the action of the Fn+F4 key combination by changing the settings in Power Manager.

In certain circumstances, the computer goes into sleep (standby) mode automatically:

vIf a “suspend time” has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within that time.

vIf the battery indicator blinks orange, indicating that the battery power is low.

Note: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically.

To cause the computer to return from sleep (standby) mode and resume operation, do one of the following:

vPress the Fn key.
