If you install a memory module that is not compatible with the computer, a
beep will sound when you turn on the power. If the incompatible module is
installed in slot A, there will be a long beep (1 second) followed by one
short beep (0.5 seconds), while if the incompatible module is in slot B, there
will be a long beep followed by two short beeps. In the event 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).
Installing memory module
There are slots for two memory modules, one over the other. The
procedures are the same for installing either module.
1. Set the computer to boot mode and turn the computer’s power off.
Make sure the Power indicator is off. Refer to the Turning off the power
section in Chapter 3, Getting Started .
2. Remove AC adaptor and all cables connected to the computer.
3. Turn the computer upside down and remove the battery pack. Refer to
the Replacing the battery pack section in Chapter 6, Power and Power-
Up Modes , for details.
4. Turn your computer over.
5. Slide the display latch on the front of the computer and open the LCD
display panel.
■ 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.
■ 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.
Use a point size1 Phillips screwdriver to remove and fasten the screws.
Use of an incorrect screwdriver can damage the screw heads.
