Additional memory module
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.
Point to note about memory module error
If you install a memory module that is not compatible with the computer, the 
Power indicator will flash 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).
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. 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.
Additional memory module 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 additional 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.
