If 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, the computer goes into sleep mode automatically:

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 mode and resume operation, do one of the following:

•Press the Fn key.

•Open the LCD cover.

•Press the power button.

Also, in either of the following events, the computer automatically returns from sleep mode and resumes operation:

•The ring indicator (RI) is signaled by a serial device or a PC Card device.

•The time set on the resume timer elapses.

Note: The computer does not accept any input immediately after it enters sleep mode. Wait a few seconds before taking any action to reenter operation mode.
