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.
Insert the two memory modules 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.
In order to ensure that the computer power is not turned on while 
working, set the Wireless communication switch to OFF.
