possible injury. If your hands, wrists, and/or arms bother you while typing,

stop using the computer and rest. If the discomfort persists, consult a

physician.

avoid stress-related injuries. Consider the following when placing your

computer.

❖Place the computer on a flat surface at a comfortable height and

distance. You should be able to type without twisting your torso or

neck, and look at the screen without slouching.

❖If you are using an external monitor, the top of the display should be

no higher than eye level.

❖If you use a paper holder, set it at about the same height and distance

as the screen.

Seating and posture

When using your computer, maintain good posture with your body relaxed

and your weight distributed evenly. Proper seating is a primary factor in

reducing work strain.

Precautions

Your notebook computer is designed to provide optimum safety and ease of

use, and to withstand the rigors of travel. You should observe certain

precautions to further reduce the risk of personal injury or damage to the

computer.

Never apply heavy pressure to the computer or subject it to sharp impacts.

Excessive pressure or impact can damage computer components or

otherwise cause your computer to malfunction.

Some PC Cards become hot with prolonged use. Overheating of a PC Card

can result in errors or instability in its operation.

Be careful when you remove a PC Card that has been used for lengthy

periods of time.

Connecting to a power source

Your computer requires power to operate. Use the power cable and AC

adapter to connect the computer to a live electrical outlet, or to charge the

computer’s battery.

Power Cable and AC adapter

Use only the AC adapter supplied with your computer or an equivalent

adapter that is compatible. Use of any incompatible adapter could damage

your computer. Toshiba assumes no liability for any damage caused by use

of an incompatible adapter.

When you connect the AC adapter to the computer, always follow the steps in

the exact order as described in the User's Manual. Connecting the power

cable to a live electrical outlet should be the last step otherwise the adapter

DC output plug could hold an electrical charge and cause an electrical shock

or minor bodily injury when touched. As a general safety precaution, avoid

touching any metal parts.

6Setting up your computer and getting started

RG 5.375 x 8.375 ver 2.3.4

Hold the power cable by its plug when you connect/disconnect it. Do NOT

pull the cable itself. Doing so may damage the power cable and result in a

short circuit or electric shock.

The power cord on this product contains lead, a chemical known to

the State of California to cause birth defects or other reproductive

harm. Wash hands after handling.

To connect AC power to the computer:

1Connect the power cable to the AC adapter.

2Plug the AC adapter into the DC-IN on the back of the computer.

3Connect the power cable to a live electrical outlet.

If the electrical outlet is live, the system indicator panel’s AC power light

( ) glows green.

Damaged power cables can cause fire or electric shock. Never modify,

forcibly bend, place heavy objects on top of, or apply heat to the power

cable.

If the power cable becomes damaged or the plug overheats, discontinue use.

There is a risk of electric shock.

Never remove the power plug from the outlet with wet hands. Doing so may

cause an electric shock.

Connecting a printer

You can connect a USB-compatible printer to your computer through a

USB port. You can also connect a parallel printer through the parallel port.

To confirm a printer’s compatibility, check its documentation.

Connecting a USB printer

To achieve the connection, you need a suitable USB cable, which may

come with your printer. Otherwise, you can purchase one from a computer

or electronics store.

Follow the manufacturer’s instructions for connecting a USB printer to your

computer.

Installing additional memory (optional)

Before you install or remove a memory module, turn off the computer using

the Start menu. If you install or remove a memory module while the

computer is in Standby or Hibernation mode, data will be lost.

A memory module must be installed in slot A. Do not try to operate the

computer with a memory module in slot B only.

Your computer is equipped with two memory slots which can provide for

various memory configurations. When additional memory is added, or

original memory replaced, it is recommended that you use only compatible

memory. In the event original memory is replaced with invalid memory, the

system will beep and will not start up beyond the BIOS memory check. A

message will display. If this occurs, contact Toshiba’s support center. See

“Toshiba voice contact” on page 27.

HINT: To purchase additional memory modules, visit the Toshiba Web site at

toshiba.com.

Your computer comes with enough memory to run most of today’s popular

applications. You may want to increase the computer’s memory if you use

complex software or process large amounts of data.

There are two memory slots. Your system may have both slots occupied.

If you use the computer for a long time, the memory modules will become

hot. If this happens, let the modules cool to room temperature before you

replace them.

Do not try to install a memory module under the following conditions. You

can damage the computer and the module.

1. The computer is turned on.

2. The computer was shut down using Standby mode.

3. Power to the DVD-ROM or multi-function drive has been turned on.

Do not install or remove a memory module while the DVD-ROM or multi-

function drive power is on.

8Setting up your computer and getting started

RG 5.375 x 8.375 ver 2.3.4

You will need a standard Phillips No.1 screwdriver and a small flat head

screwdriver to install a memory module.

To avoid damaging the computer’s screws, use a standard Phillips

screwdriver that is in good condition.

1If the computer is on, turn it off.

See “Turn Off or Shut down command” in your electronic user’s

guide.

2Unplug and remove any cables connected to the computer.

3Open the display panel and remove the panel above the keyboard that

contains the power button.

When removing the computer’s power button panel to install additional

memory, be careful not to damage the display or circuit board.

Using a flat-head screwdriver to pry off the panel

You can pry the panel out of its position by using a flat-head

screwdriver. Starting at the left or right side, carefully wedge the flat-

head screwdriver between the panel and the surrounding housing.

Grasp the end of the panel and lift up until the panel comes free.

4Remove the three screws that hold the keyboard in place, and remove

the keyboard retaining brace.

you may have built up.

To avoid damaging the memory module, be careful not to touch its pin

connector (on the side you insert into the computer).

Avoid touching the connectors on the memory module or on the computer.

Grease or dust on the connectors may cause memory access problems.

8Insert the memory module in a slot and gently press it down into

place.
