6-1. Opening the computer case
Always consult with your service representatives before opening the computer
case.
Follow the guidelines below when opening the case.
Opening and closing the computer case
ãQuit all running programs.
ãTurn off the computer and monitor, and unplug and remove the power cords.
ãKeep magnetic objects such as screw driver away from the parts inside the com-
puter.
ãOpen the computer case in a safe, clean area.
ãThe static electricity can damage the parts inside the computer. Touch a bare,
unpainted metal part of the computer for 2~3 seconds to remove the static elec-
tricity before opening the computer case.
ãAlways wear gloves to avoid injury when disassembling the computer.
Make sure that there is no metallic object left inside the computer before closing the case.
There is the risk of electric shock or fire.

ãBefore removing the connector, check the status of connection and make a note.
ãAline the groove to the right direction when connecting floppy disk drive connector, hard
disk/CD-ROM connector.
ãMatch the pin number with the color of cable. There is a risk of disfunction to the computer.
ãThere is a risk of explosion if battery is replaced by an incorrect type. Dispose of used batter-
ies according to the instructions.
ãThere is a risk of explosion if the backup(standby) RTC battery is replaced by an incorrect type.
ãDispose of used backup(stadby) RTC battery according to your local ordinances or regulation.

6-5. Increasing the memory
If you run out of memory while using the computer, you may want to increase the
amount of memory in your computer.
About memory
Your computer uses DDR(Double Data Rate) SDRAM DIMM(Dual In-Line Memory
Module) with 184 pins. Your computer supports Unbuffered DDR SDRAM DIMM of
256MB up to 512MB in size in each socket, and 2GB total.
Before increasing the memory
ãAlways wear gloves to avoid injury when disassembling the computer
ãStatic electricity can damage memory modules be sure to minimize the static
electricity when replacing memory.
ãMake sure to replace the memory of the same type as the installed memory.
ãDIMM is different from SIMM in that it is configured for 64 bit operation; there-
fore, your computer can operate with only one DIMM installed.
ãWindows 95, 98SE, ME supports memory up to 512MB total. Increasing the memory
beyond 512MB in these systems may cause errors while using the computer.
Note
ãUse a 2.5V DDR SDRAM DIMM.(The shape of the memory may be different depending
on the model) DDR SDRAM enhances the rate of data transmission of the SDRAM and
looks different from SDRAM.
Note
DDR

Purchasing a memory
Check the type of memory installed in your computer and refer to the memory configura-
tion chart before purchasing a memory.

ãUse Unbuffered DDR SDRAM DIMM only to increase the memory.
ãDual channel mode operates when each identical memory is installed in the same color
of DIMM slot.

ãDual channel improves the efficiency of the system.
ãEach identical memory should be used for dual channel setting.
ãDual channel setting is recommended.

ⓟPull the latch on each side of a memory socket to release the memory.
Replacing the memory
ⓟ
Align the notch at the bottom of the
memory with a protrusion in the middle
of the socket, and then insert the
memory straight down.
Installing a memory
Latch
ãBefore opening the case, turn off the
computer and peripheral devices, and
remove the power cords.
Note
ãFor dual channel system, each mem
ory should be installed in independent
slot(1&3 slot or 2&4 slot) when using
DDR Memory
It is recognized as a single channel if
there is a difference between dual
channel 1 and 3, 2 and 4.
