Why do I not get the highest possible resolution out of my
external monitor when I am using the LCD and external monitor
at the same time?

Solving Computer Problems

You can set any resolution for either the ThinkPad LCD or
the external monitor. When you use both at the same time,
the resolution of both is the same. If you set a higher
resolution for the ThinkPad LCD, you can see only part of
the screen at a time. You can see other parts by moving
the image with the TrackPoint or other pointing device. You
can change the display output type to the LCD, external
monitor, or both with the Display Device buttons of the
ThinkPad Configuration program or with Fn+F7.

You can set up the external monitor as follows:

1

Double-click on My Computer, Control Panel, and
then Display. The “Display Properties” window
appears.

2

Click on the Settings tab.

How can I maximize battery life?

To maximize battery life, do the following:

Use the battery until the charge is completely depleted

(until the battery and power LEDs flash in unison).

Recharge the battery completely before using (the
battery is fully charged when the AC Adapter is
plugged in and the battery LED is green).

For a new battery or a battery that you have not used
recently:

1. Use the battery until the charge is completely
depleted (until the battery and power LEDs flash
in unison).

2. Recharge completely before using (the battery is
fully charged when the AC Adapter is plugged in

The computer enters suspend mode automatically when the processor
temperature reaches a certain level. This is not a defect.

Make sure that:

If these items are correct, have the computer serviced.
The battery pack power is getting low. Connect the AC Adapter to the

computer, or replace the battery pack with a fully charged one.

The computer automatically enters suspend or hibernation mode when the
battery power is empty. Do one of the following:

Check if an external monitor was not connected before the computer entered
suspend mode. Do not disconnect the external monitor while the computer

is in suspend mode or hibernation mode. If no external monitor is
attached when the computer resumes, the LCD remains blank and output
is not displayed. This restriction does not depend on the resolution value.

With ac power, your computer cannot enter suspend mode if an IBM
communication card is installed. A modem card cannot prevent suspend mode,
however. Your computer cannot enter hibernation mode under ac power if
either an IBM communication card or a modem card is installed.

If your computer does not enter suspend or hibernation mode and IBM
communication card or modem card is not installed, check if suspend or
hibernation mode is disabled. See “Basic” in the
information.
