Display  
The large graphics display offers excellent viewing, display quality and desktop performance graphics. The  
computer supports a Thin-Film Transistor (TFT) liquid crystal display (LCD) displaying 24-bit true-color at  
800x600 Super Video Graphic Array (SVGA) or 1024x768 eXtended Graphics Array (XGA) resolution.  
Video performance  
2X AGP video graphic accelerator with 8 MB of video memory boost video performance.  
Simultaneous display  
The computers large display and multimedia capabilities are great for giving presentations. If you prefer, you  
can also connect an external monitor when giving presentations. This computer supports simultaneous LCD  
and CRT display. Simultaneous display allows you to control the presentation from your computer and at the  
same time face your audience. You can also connect other output display devices such as LCD projection  
panels for large-audience presentations.  
Dual Display  
The computers unique graphics chip takes advantage of Windows 98 multi-display capability, allowing you to  
extend your desktop to an external display device, such as an external monitor projector. With this feature  
enabled, you can move program windows to/from the computer LCD and the external monitor.  
Power management  
The power management system incorporates an "automatic LCD dim" feature that automatically dims the LCD  
when the computer is powered by a battery pack to conserve battery power. See Power Managementon  
page 26 for more information on power management features.  
Opening and closing the display  
To open the display, slide the display cover latch to the left and lift up the cover. Then tilt it to a comfortable  
viewing position. The computer employs a microswitch that turns off the display (and enters standby mode) to  
conserve power when you close the display cover, and turns it back on when you open the display cover.  
NOTE:  
If an external monitor is connected, the computer turns off the display (but does not enter standby  
mode) when you close the display cover.  
To close the display cover, fold it down gently until the display cover latch clicks into place.  
To avoid damaging the display, do not slam it when you close it. Also, do not place any object on top of the  
computer when the display is closed.

4th: LANDesk (R) Service  
Agent  
Setting the Boot Drive Sequence  
The Boot Drive Sequence section lists boot priorities (1st, 2nd, 3rd and 4th) for bootable drives in your  
computer.  
For example, the default value (1st:Floppy Disk, 2nd:CD-ROM, 3rd:Hard Disk and 4th:LANDesk (R) Service  
Agent) tells the computer to first search for a bootable floppy disk in the floppy drive. If it finds one present, it  
boots up from that floppy disk. If not, the computer continues to search for a bootable CD-ROM in the CD-  
ROM drive. If it cannot boot up from the CD-ROM drive, it continues by booting up from the hard disk.  
To set the boot drive sequence, use the cursor up/down keys to select a priority level (1st, 2nd, 3rd and 4th),  
then use the cursor left/right keys to select the device for that priority level.

To verify the symptom of the problem, power on the computer using each of the following power sources:  
1. Remove the battery pack.  
2. Connect the power adapter and check that power is supplied.  
3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by  
the battery pack.  
If you suspect a power problem, see the appropriate power supply check in the following list:  
Check the Power Adapter”  
Check the Battery Pack”  
Check the Power Adapter  
Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power  
adapter cable. See the following figure  
Pin 1: +19 to +20.5V  
Pin 2: 0V, Ground  
1. If the voltage is not correct, replace the power adapter.  
2. If the voltage is within the range, do the following:  
Replace the System board.  
If the problem is not corrected, see Undetermined Problems.  
If the voltage is not correct, go to the next step.  
NOTE: An audible noise from the power adapter does not always indicate a defect.  
3. If the power problem occurs only when the port replicator is used, replace the port replicator.  
4. If the power-on indicator does not light up, check the power cord of the power adapter for correct  
continuity and installation.  
5. If the operational charge does not work, see Check the Battery Pack.  
Chapter 4  
69  
     
Check the Battery Pack  
To check the battery pack, do the following:  
1.  
2.  
Power off the computer.  
Remove the battery pack and measure the voltage between battery terminals 1(+) and 7(ground). See the  
following figure  
3.  
If the voltage is still less than 8.0 Vdc after recharging, replace the battery.  
To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50%  
of the total power remaining when installed in the computer.  
If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.  
Re-install the battery pack.  
If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light  
up, replace the system board.  
Touchpad Check  
If the touchpad doesnt work, do the following actions one at a time to correct the problem. Do not replace a  
non-defective FRU:  
1.  
2.  
3.  
4.  
Reconnect the touchpad cables.  
Replace the touchpad cables.  
Replace the touchpad.  
Replace the system board.  
After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement  
can occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware  
problem. No service actions are necessary if the pointer movement stops in a short period of time.

Index of Error Message  
The symptom-to-FRU index lists the symptoms and errors and their possible causes. The most likely cause is  
listed first.  
NOTE:  
Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU  
replacement does not solve the problem, put the original part back in the computer. Do not replace a  
non-defective FRU.  
This index can also help you determine the next possible FRU to be replaced when servicing a computer.  
If the symptom is not listed, Undetermined Problemson page 79.
