Point to note about memory module error

If you install a memory module that is not compatible with the computer, the

Power indicator will flashes (on for 0.5 seconds, off for 0.5 seconds) in the

following ways;

■ If there is an error in only Slot A or no memory module is inserted in

Slot A: repeatedly flashes amber twice, then green.

■ If there is an error in Slot B: repeatedly flashes amber, then green twice.

■ If there are errors in both Slot A and Slot B: repeatedly flashes amber

twice, then green twice.

In all instances you should shut down the computer and remove the

incompatible module(s).

Installing a memory module

The computer contains slots for two memory modules, one positioned

immediately over the other - the procedures are the same for installing

either module.

1. Set the computer to Shut down mode and turn its power off - make sure

the Power indicator is off (refer to the Turning off the power section in

Chapter 3, Getting Started if required).

2. Remove the AC adaptor and all cables and peripherals connected to

the computer.

■ Use only memory modules approved by TOSHIBA.

■ Do not try to install or remove a memory module under the following

conditions.

a. The computer is turned on.

b. The computer was shut down in either Sleep or Hibernation Mode.

c. Wake-up on LAN is enabled.

d. The wireless communication switch is turned on.

■ Be careful not to let screws or other foreign matter fall into the

computer. It could cause malfunction or electric shock.

■ Expansion memory is a precision electronic component that may be

fatally damaged by static electricity. Since the human body can carry

static electricity, it is important that you discharge yourself before

touching or installing any expansion memory modules. To discharge

your body’s static electricity, simply touch any metal close to you with

bare hands.

■ In order to ensure that the computer power is not turned on while

working, set the Wireless communication switch to OFF.

Use a #0 point Phillips screwdriver to remove and fasten the screws - the

use of an incorrect screwdriver can damage the screw heads.
