Will not suspend even if LCD is closed in the Power Management Properties window. Then only the LCD turns off.)

In certain circumstances, the computer goes into 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 the time set.

vIf the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the “Power Management Properties” window, the computer goes into hibernation mode.)

Note: Even if you don’t set the low-battery alarm, the charge indicator lets you know that the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate.

Any one of the following events causes the computer to resume operation from standby mode:

vThe Fn key is pressed.

vThe LCD cover is opened.

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

vThe power switch is turned on.

vThe resume timer is set. In Windows which has the Scheduled Tasks, the Scheduled Tasks setting has priority over the setting in IBM BIOS Setup Utility.

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