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
the Turning off the power section in Chapter 3, Getting Started if
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.
