Additional memory module
You can replace with an additional memory in order to increase the amount 
of system memory that is available.
This section describes how to install and remove optional memory 
modules.
Installing a memory module
To install a memory module:
1. Shut down the computer - make sure the Power indicator is off (refer to 
 section in Chapter 3, 
required).
2. Remove the AC adaptor and all cables and peripherals connected to 
the computer.
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.
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 is enabled.
e. USB Sleep and Charge function is enabled. 
Be careful not to let screws or other foreign matter fall into the 
computer. It could cause malfunction or electric shock.
Additional memory modules are precision electronic components 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.
Turn off the power and disconnect the AC adaptor when installing or 
replacing a memory module.
If you use the computer for an extended period of time, the memory 
modules and the circuits located close to the memory modules will 
become hot. Allow then to cool to room temperature before you replace 
them.
