Optional Devices Memory expansion You can install additional memory into the computer in order to increase the amount of system memory that is available. This section describes how to install and remove optional memory modules. ■ You should place a mat beneath the computer in order to prevent the computer's lid from becoming scratched or damaged when you are installing/replacing the memory module. In this instance you should avoid mats that are made of materials that hold or generate static electricity. ■ When installing or removing a memory module, you must ensure that you do not touch any other internal areas of the computer. ■ The Front-side System Bus Speed (FSB) for this computer is 533MHz. While 667MHz memory modules can be installed, the FSB will depend on 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. Point to note about memory module error If you install a memory module that is not compatible with the computer, a "beep signal" will sound when you turn on the power. If the incompatible module is installed in Slot A, there will be a long beep of one second, followed by one short beep of half a second, while if the incompatible module is in Slot B, there will be a long beep followed by two short beeps. In the event that 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).
