6-3. Internal Connectors
Connectors are configured in a certain way at the factory, and connectors show the
connection status between the main board of the computer and peripherals.
(Connector configuration depends on product models.)
Before separating the connector, check the connection state of the connectors and leave a
record on the state.
Link the floppy disk driver connector and the hard disk/CD-ROM connector in the correct
direction.
The Pin Number and the color of the connector cable must match. Otherwise, an error may
occur in the computer.
Risk of explosin if battery is replaced by an incorrect type. Dispose of used batteries
according to the instructions.
There is a risk of explosion if the backup(standby) RTC battery is replaced by an incorrect
type. Dispose of used backup(stadby) RTC battery according to your local ordinances or
regulation.

6-4 Replacing the CPU
To upgrade the CPU for better performance of the computer, you need to replace the
CPU first. Check the location and the type of the CPU in the main board, and do the
following. (Shape of the CPU FAN and CPU replacement methods may differ by
model.)
Align the groove to the right position,
pins can easily be broken.
Unfasten four screws fixing the CPU fan as shown in the figure.
Turn the CPU socket handle as shown in the figure of Step , and open the cover
as shown in the figure of Step .
Remove the CPU fan as shown in the figure.
System Expansion 73
Always wear gloves to avoid injuries.
Lift the CPU up carefully to remove it from the main board.
Insert the new CPU with caution in the CPU socket in the correct direction and
close the cover and then put down the handle of the CPU socket
Insert the CPU FAN as shown in the figure, and fix it with four screws.

6-5. Expanding the Computer Memory
You may expand the memory capacity, if needs be.
About Memory
This system uses a 240-pin memory module called Double Data Rate-2 (DDR-2),
not the old 184-pin memory module called Double Data Rate (DDR). The main
board can support maximum 2GB in memory.
Before Expanding the Memory
When disassembling the computer, wear gloves to protect internal parts of the
computer and slot cards from damage.
As the memory is sensitive to static electricity, be careful with the static electrici-
ty when removing or installing a memory.
Check the specifications of the current memory and the new memory before
expanding the memory.
Unlike SIMM, DIMM is of 64 bits. Therefore, single DIMM can function, and you
can add DIMM by one.
Windows 95, 98SE, and ME support maximum 512MB. Installing a memory with higher
capacity than 512MB may cause malfunctioning of the system.
Note
Note
When expanding the memory, add a memory with the same specification (DDR-2
SDRAM for 1.8V). (The shape of the memory may differ depending on the product
model.)
The DDR-2 memory provides greatly improved transmission rate than existing memo-
ries, and is differently shaped.
75System Expansion
Refer to the following when expanding memory.
This computer supports PC3200/4300, DDR-2 specification.
When expanding the memory, use only unbuffered DDR SDRAM DMM
When inserting two same memories in same-colored DIMM slots, the computer will oper-
ate in Dual Channel mode.
FSB Frequency
400/533 MHz
Usable Memory
PC3200/4300-DDR-2 SDRAM 400/533MHz
Preparing a Memory
Before purchasing memory, study the specifications and features of the current
memory.
Specification : PC3200/4300 (240-pin DDR-2 SDRAM)
Rate : 400MHz (200MHz 2), 533MHz (266MHz 2)

The computer operates faster in Dual Channel mode.
Use the same memory to operate the computer in Dual Channel mode.
It is recommended to use Dual Channel mode.
Note
76 System Expansion
Main board configuration, memory socket and memory type may differ by model.
Loosen the screws on the rear panel
of the computer, and remove the
cover.
Release the latches from both flanks of the memory. The memory will be
removed automatically.
Replacing the Memory
Before opening the computer cover,
turn off the power and all peripherals
connected to the computer. Disconnect
all power cables.
Note
Lay the latches outwards from the
memory socket.
Insert the memory (DIMM) vertically in
the socket in line with the grooves as
shown in the figure.
Installing Memory
When using a DDR-2 memory, the mem-
ory must be installed in each channel for
Dual Channel mode.
1-3 and 2-4 of dual Channels No. 1 ~ 4
The memory will be automatically installed
even if not latched. However, it is recom-
mended to fasten the latches until the
memory is completely fixed.
Note
The memory will be automatically
installed even if not latched. However, it
is recommended to fasten the latches
until the memory is completely fixed

Checking the Expanded Memory
Turn on the power after installing the memory. Then, the computer will detect the
memory so that you don't need to change the system setup. The capacity of the
installed memory is checked as follows.
Connect the power cord and other cables, and turn on the computer and the moni-
tor. Then, the initial screen to check the status of the computer will appear.
When the following screen appears, press [Esc] key. Then, POST screen will
appear.
On the next screen, press [Pause] to freeze the screen temporarily and to check
the Memory Testing : XXXXXX OK part.
After checking the memory, press the [Esc] key. Windows screen will proceed.
In the case that the logo screen is processed too fast to stop, press [Delete] key on the LG
logo screen. Then, select Advanced BIOS Features Full Screen Logo Show
Selectable, and change status from Enabled to Disabled.

6-6. Adding a Hard Disk
This computer supports up to four serial ATA controllers, and you can add one hard
disk drive.
The following is when you purchase a hard disk and installs it, and describes the
most common case when you add a hard disk to a computer that is already equipped
with one hard disk.
When disassembling the computer, wear gloves to protect internal parts of the computer
and slot cards from damage.
Use screws compatible with specification when installing the hard disk in the main body.
Otherwise, critical damage may be done to electronic parts. For stable use of the hard
disk, fix the hard disk in the main body of the computer to prevent vibration.
Before Adding a Hard Disk
Adding a Hard Disk
Write down the capacity, the cylinder count, the numbers of heads
and sectors of the hard disk marked on the upper part of the hard
disk. They are necessary for system setup (depending on the
product model.).
