Memory expansion

You can install additional memory in the computer’s memory module slot to increase the amount of RAM. This section describes how to install and remove a memory module.

■Place a mat beneath the computer to ensure that you do not scratch lid

when replacing the memory module - you must ensure that this mat does not generate or hold a static electric charge.

■When you install or remove a memory module, ensure that you do not touch any other internal areas of the computer.

■Use only memory modules approved by TOSHIBA.

■Do not try to install or remove a memory module under the following conditions as you can damage the computer and/or the module, and you risk losing data:

a.The computer is turned on.

b.The computer was shut down using either Standby Mode or Hibernation mode.

c.Wake-up on LAN is enabled.

d.Wake-up on Wireless LAN is enabled.

■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.

If you install a memory module that is not compatible with the computer, a beep will sound when you turn on the power. If the incompatible module is installed in slot A, there will be a long beep (1 second) followed by one short beep (0.5 seconds), while if the incompatible module is in slot B, there will be a long beep followed by two short beeps. In the event both modules are incompatible, there will be a long beep followed by one short beep, a pause, and then a long beep followed by two short beeps. In all instances you should shut down the computer and remove the incompatible module(s).

Use a #0 point Phillips screwdriver to remove and fasten the screws. Use of an incorrect screwdriver can damage the screw heads.
