Touchpad

The built-in touchpad is a PS/2-compatible pointing device that senses
movement on its surface. This means the cursor responds as you move
your finger on the surface of the touchpad. The central location on
the palm rest provides optimum comfort and support.

Touchpad basics

The following teaches you how to use the touchpad:

• Move your finger across the touchpad to move the cursor.

• Press the left (1) and right (2) buttons located on the edge of the

touchpad to do selection and execution functions. These two
buttons are similar to the left and right buttons on a mouse.
Tapping on the touchpad produces similar results.

Charging the battery

To charge the battery, slide the battery pack into the battery bay and
plug the AC adapter into the computer and an electrical outlet.

Charging modes

The adapter has two charging modes:

• Rapid mode
The computer uses rapid charging when power is turned off and a

powered AC adapter is connected to it. In rapid mode, a fully
depleted battery gets fully charged in approximately 3 hours.

• Charge-in-use mode
When the computer is in use with the AC adapter plugged in, the

computer also charges the battery pack if installed. This mode will
take longer to fully charge a battery than rapid mode. In charge­in-use mode, a fully depleted battery gets fully charged in
approximately 4.5 hours.

33

Note: We suggest that you charge the battery pack before
retiring for the day, letting it charge overnight before traveling.
This ensures a fully charged battery for use the next day.

Checking the battery level

Using the Windows battery meter

The Windows battery meter indicates the present battery level. Simply
rest your cursor on the battery meter (or AC plug) icon on the taskbar
to see the present charge level of your battery.

Optimizing battery life

This section helps you get the most out of battery operation.
Optimizing battery life prolongs the charge/recharge cycle and
improves recharge efficiency. Follow these suggestions to optimize
and maximize battery power:

• Purchase an extra battery pack.

TMa550.book Page 34 Wednesday, October 3, 2001 10:57 AM

2 Operating on battery power34

• Use the AC adapter whenever possible so that the battery is
reserved for on-the-go computing.

• Keep the battery pack in the computer powered by the AC
adapter. The constant trickle charge maintains the battery level to
eliminate the battery self-discharge effect. The charge-in-use
function also charges the battery pack.

• Disable the parallel port if no devices are connected to this port.
You can do this through the BIOS Setup Utility. See “Others” on
page 71.

• Eject the PC Card from the slot when it is not in use, since the PC
Card draws extra power. See “Ejecting a card” on page 44.

• Store the battery pack in a cool, dry place. The recommended
storage temperature for battery packs ranges from 10 to 30
degrees Celsius. The higher the storage temperature, the faster
the battery pack self-discharges.

• The batteries can be recharged about 400 times when used as
directed. Excessive recharging decreases battery life.

• Take care of your battery pack and AC adapter. See “Taking care
of your computer” on page iv of the preface.

Battery-low warning

You never have to worry about battery power as long as you are using
the AC adapter. However, when you operate the computer on battery
power, pay extra attention to the battery gauge on the status LCD.

Warning! Connect the AC adapter to the computer as soon
as possible. Data is lost when computer power is cut off
during Standby mode.

This chapter instructs you on how to deal
with common system problems. Read it
before calling a technician if a problem
occurs. Solutions to more serious problems
require opening up the computer. Do not
attempt to open and service the computer

Frequently-asked questions

This is a list of possible situations that may arise during the use of your
computer, and it gives easy answers and solutions to these questions.

I press the power switch, but the computer does not start or boot-up.

Look at the Power status indicator:

• If it is not lit, no power is being applied to the computer. Check
the following:

• If you are running on battery power, it may be low and unable

to power the computer. Connect the AC adapter to recharge
the battery pack.

• Make sure the AC adapter is plugged in properly to the

computer and to the power outlet.

• If it is lit, check if a non-bootable (non-system) diskette is in the
floppy drive. Remove or replace it with a system diskette and press
Ctrl-Alt-Del to restart the system.

77

The operating system files may be damaged or missing. Insert the
startup disk you created during Windows setup into the floppy drive
and press Ctrl-Alt-Del to restart the system. This will diagnose your
system and make necessary fixes.

Nothing appears on the screen.

The computer’s power management system automatically blanks the
screen to save power. Press any key to turn the display back on.

If pressing a key does not turn the display back on, two things might
be the cause:

• The brightness level might be too low. Press Fn-↑ and Fn-↓ to
adjust the brightness level.

• The display device might be set to an external monitor. Press the
display toggle hot key Fn-F5 to toggle the display back to the
computer.

Image is not full-screen.

Make sure the resolution is set to a resolution your system supports
natively. Right-click on your Windows desktop and select Properties to
bring up the Display Properties dialog box. Then click on the Settings

TMa550.book Page 78 Wednesday, October 3, 2001 10:57 AM

6 Troubleshooting78

tab to make sure the resolution is set to the appropriate resolution.
Resolutions lower than the specified resolution are not full-screen on
the computer or on an external monitor.

No audio from the computer.

Check the following:

• The volume may be muted. In Windows, look at the volume
control icon on the taskbar. If it is crossed-out, click on the icon
and deselect the Mute option.

• The volume level may be too low. In Windows, look at the volume
control icon on the taskbar. Click on the icon and adjust the level.
You can also use the volume control knob on the front panel of
the computer to adjust the volume.

If headphones, earphones or external speakers are connected to the
speaker/headphone-out port on the computer, the internal speakers
automatically turn off.

External microphone does not work.

Check the following:

• Make sure the external microphone is connected to the
microphone-in jack on the computer.

• If you cannot hear playback, the speakers may be muted.

How do I eject the optical drive tray with the computer turned off?

There is a emergency eject hole on the optical drive. Simply insert the
tip of a pen or paperclip and push to eject the optical drive tray. For
the location of the emergency eject hole, see “Left view” on page 5.

The keyboard does not respond.

Try attaching an external PS/2 or USB keyboard to the appropriate port
on the computer. If it works, contact your dealer or an authorized
service center as the internal keyboard cable may be loose.

The floppy drive cannot access a diskette.

Check the following:

• Make sure the diskette is properly inserted in the floppy drive.

• Make sure the diskette is formatted.

TMa550.book Page 79 Wednesday, October 3, 2001 10:57 AM

• If the diskette is not the cause of the problem, the floppy drive
may be dirty. Clean it using a drive cleaning kit. Follow the
instructions included with the kit.

The CD or DVD drive cannot access a disc.

Check the following:

• Make sure the disc is supported by the drive. If your computer has
a CD-ROM drive, it can read CDs but cannot read DVDs. If your
computer has a DVD drive, it can read DVDs in addition to CDs.

• When placing the CD or DVD in the drive tray, make sure it is
secure in the spindle on the drive tray.

• Make sure the CD or DVD is free from scratches or smudges. If the
CD or DVD is dirty, clean it using a disc cleaning kit. Remember to
follow the instructions included with the kit.

• If the problem does not lie with the disc, your CD or DVD drive
may be dirty. Clean it using a drive cleaning kit. Follow the
instructions included with the kit.

79

The printer does not work.

Check the following:

• Make sure that the printer is connected to a power outlet and it is
turned on.

• Depending on your printer connection (USB or parallel), make sure
the printer cable is connected securely to the appropriate ports on
both the computer and the printer.

• If you use a parallel port, access the BIOS Setup Utility by pressing
F2 after restarting your system. Go to the Others screen and
verify that the parallel port is enabled. See “Others” on page 71.

I want to set up my location to use the internal modem.

Follow these steps:

1 Click on Start, then click Control Panel.
2 Double-click on Phone and Modem Options.
3 In the Dialing Rules tab, begin setting up your location.

Refer to the Windows Help and Support and the modem manual.

Why can’t I charge my battery to 100% charged when it is 99-95%

charged?

To preserve the life of the battery, the system only lets you charge the
battery when its capacity falls below 95%. However, it is recommended
that you bring an extra battery and let the battery in the system use up
its power before charging it.
