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 prevent scratching or damaging the computer's lid when installing/replacing the memory module. Avoid mats made of materials that generate static electricity.

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

■Insert the two memory modules of the same specifications and capacity into Slot A and Slot B respectively. The computer will operate in dual channel mode.

You can access the inserted memory modules efficiently in dual channel.

■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.Wake-up on Wireless LAN is enabled.

e.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.

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 point size 1 Phillips screwdriver to remove and fasten the screws. Use of an incorrect screwdriver can damage the screw heads.
