Before replacing parts make sure that latest BIOS and drivers are installed before replacing any parts (FRUs) listed in this.
Use the following strategy to prevent unnecessary expense for replacing and servicing parts
1. If you are instructed to replacing a part but the replacement does not correct the problem, reinstall the original part before you continue.
2. Some computers have both a processor board and system board. If you are instructed to replace either the processor board or the system board, and replacing one of them does not correct the problem, reinstall that board, and then replace the other one.
3. If an adapter or device consists of more than one part, any of the parts (FRUs) may be the cause of the error. Before replacing the adapter or device, remove the parts (FRUs), one by one, to see if the symptoms change. Replace only the part that changed the symptoms.
Caution: The BIOS configuration on the computer you are servicing may have been customized. Running Automatic Configuration my alter the settings. Note the current configuration settings; then, when service has been completed, verify that those settings remain in effect.
Strategy for replacing a hard-disk drive
You have to get a User’s approval before formatting or replacing a hard-disk drive. You must let the User know that the user is responsible for the loss data.
Caution: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten.
Before the computer is powered-on after part (FRU) replacement, make sure all screws, springs, and other small parts are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical shorts.
Some standby batteries contain a small amount of nickel and cadmium. Do not disassemble a standby battery, recharge it, throw it into fire or water, or short-circuit it. Dispose of the battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing. Use of an incorrect battery can result in ignition or explosion of the battery.
Before removing any part (FRU), turn off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
Processors
Intel Core2 Duo/Solo/Mobile Intel Celeron Processor™(L2 Cache Size: 1MB/2MB/4MB/6MB/8MB, FSB:533/800MHZ are supported.).
The user must not replace or expand the CPU capacity arbitrarily. The CPU capacity differs depends on model type.
Main Memory
Maximum Capacity: Each slot is 2048MB and can be expanded to 4096MB.
SO DIMM Type for Memory Expansion: DDR2/DDR3 SDRAM SO-DIMM(256MB, 512MB, 1024MB, 2048MB)
Memory types and specifications may differ by model type.
To use two 2GB memory cards, the machine must run on 64bit OS. 32bit Vista/XP OS does not support 4GB memory.
Secondary Storage
2.5" Hard Disk Drive (S-ATA)
The hard disk capacity and the type depend on the notebook PC model.
Optical Disk Drive
The specifications may differ by model type.
Video
Mobile Intel Graphic Media Accelerator 4500MHD (Dynamic Video Memory Technology)
The DVMT actively utilizes part of the system memory when processing large graphic data like 3D graphics.
Therefore, the size of the graphic memory is displayed as the sum of the actual graphic memory size and the utilized amount of memory, which is decided by the size of system memory.
NVIDIA Geforce 9600M GT (W/GDDR3 256M ) with TurboCache 320MB~1535MB
NVIDIA Geforce 9600M GT (W/GDDR3 512M) with TurboCache 576MB~1791MB
NVIDIA Geforce 9300M GS (W/GDDR3 256M) with TurboCache 320MB~1535MB
TurboCache - This technology actively utilizes part of the System Memory when processing large graphic data like 3D graphics. The size of the utilized memory is determined by the Video Memory size and System Memory Size.
If TurboCache technology is applied to the Graphics Memory, the System Memory can allot up to 320MB out of 512MB and up to 1791MB out of 4096MB for large graphic data.
Specifications may differ by model type.

BIOS Flash
You can update BIOS using USB Device (FDD/USB Memory)
Because this system is not equipped with any USB Device, you have to use an external USB Device for a BIOS update. In order to boot up with an USB Device, please set Removable Device as the first boot up drive in the boot menu of BIOS Setup.
How to update flash Rom in Dos

8. After flashing is completed, the computer turns off with automatic movement.
10. Press [F2] Key, then you can see the BIOS SETUP UTILITY screen as below.
11. It selects the:” Load Optimal Dafault” and it summons a BIOS settings at initial value.
12. It selects the “Exit & Saving Change” and it stores system a settings and the reboot.
BIOS Release Process and Making Bootable CD
1. LGE(Korea) will upload BIOS Image(*.iso) to GCSC(Global Cyber Service Center:http://biz.lgservice.com) when BIOS should be updated.
2. BIOS will include both System BIOS and EC(Embedded Controller) BIOS.
3. Service center can download BIOS file from GCSC and update BIOS according to below procedure.
4. Service center will make Bootable Image CD with Image file(*.iso) as below.
a. Insert empty disc to CD-RW Drive and start Nero “StartSmart”.
b. Select “Nero Express”.
c. Select “Disc Image or Saved Project.
d. Select File Format as "Image Files(*.iso)".
e. Open Image File(*.iso) which is sent from LGE.
f. Tab Burn then burning will be started.
g. Burn process completed as below, and tab “OK.
BIOS / EC Flash Process.
1. Insert Bootable CD in PC, and Turn it on, then PC will boot by DOS mode as below. (If the EC is not correct or old version, then automatically update EC first and reboot again)
