Procedure:
• Check for any media still inserted on the unit (e.g. CD/DVD/Floppy Disks/Etc.)
• Shut-down the system
• Be sure that all applications are closed and all opened files/documents have been saved.
• Turn off the system and any attached peripherals.
• Disconnect the system and any attached peripherals from AC power.
• Disconnect any telephone or telecommunications lines from the system.
• Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic discharge (ESD) damage.
• After removing any system component, carefully place the removed component on an anti-static mat.
2. Before opening the unit, you must first remove the battery.
3. Remove the HDD from the unit. Take note of the capacity of the HDD.
4. Remove all installed Memory modules. Take note of the quantity and capacity.
Caution: Memory is easily damaged and should not be forced into the slot when replacing it.
5. Disconnect the cable from the Modem Daughter Card and remove the MDC from the Mother board.
18. Power-on clients unit, & run diagnostics if available to check functionality of all installed components. Be sure to check the capacity of all installed components and compare if it tallies with the original unit configuration.
19. BIOS setup
• Warning: Changing motherboards from one brand to another sometimes requires reformatting the hard drive and reloading the operating system. Choose your motherboard and read the motherboard manual thoroughly before upgrading.
• BIOS is a program located on a Read-Only Memory (ROM) chip on the motherboard. This program will not be lost when you turn the main power to your computer off. This program is also sometimes referred to as the boot program. It is the only channel for the hardware circuit to communicate with the operating system. Its main function is to manage the setup of the basic parameters for motherboard and interface cards. These parameters include simple ones such as time, date, hard disk drive, as well as more complex ones such as hardware synchronization, and device operating mode.
• WARNING: Do not change any parameters inside the BIOS unless you know what you are doing! The parameters inside the BIOS are used to set up the hardware synchronization or the device operating mode. If these parameters are incorrect, they may produce error, the computer may crash, and sometimes you may even not be able to boot the computer after it crashes. We suggest you not to change the parameters inside the BIOS unless you are familiar with them.
• When you start your computer, the computer is first controlled by the BIOS program. The BIOS runs an auto-diagnostic procedure for all the necessary hardware, configures the parameters for the hardware synchronization, and detects all the hardware. After it completes these tasks, BIOS gives up the control of the computer to the program of the next level, which is the operating system.
• Since the BIOS is the only channel for hardware and software to communicate, it will be the key factor to system stability and optimal performance. You lose your customized BIOS setting if the CMOS battery on your motherboard is removed or fails. Your BIOS goes back to its original manufacturer default if that happens.stalled components. Be sure to check the capacity of all installed components and compare if it tallies with the original unit configuration. Reinstall drivers as necessary.

WARNING: Handle motherboards gently by the edges. Some of the component leads under the board have sharp edges and may cause serious injury. To prevent electrostatic discharge damage to the components on your motherboard, do not remove the motherboard from the static-shielded bag until you have discharged any static electricity from your body by touching any unpainted surface on the case of your computer.
6. Remove any installed optical drives from the unit. Before removing the optical drive, be sure to disconnect all optical drive cables from the MB. Please note the capacity and speed of the installed unit.
7. Remove installed FDD if there is any. Before removing the FDD, be sure to disconnect all FDD cables from the MB.
8. Remove the screws from the keyboard bezel and gently lift it from the chassis.
Caution: Extra care should be taken when removing the bezel, as excessive force may cause it to crack and break.
9. Remove the screws from the keyboard. Gently slide the keyboard away from the touchpad to release the tabs. Gently lift up the keyboard from the back right corner to approximately a 30 degree angle. Don’t pull the keyboard straight up as it is still physically attached to the MB via flex connectors and attached to be palm rest via tabs at the side of the keyboard. Remove the flex cables from the motherboard.
14. Remove all the screws connecting the mother board to the base cover and remove the mother board from the base cover.
15. Check the MB for any removable items such as CMOS batteries, Audio boards, Processor, etc.
Caution: Use extreme caution when removing the processor. The socket and processor are highly sensitive products and should not be touched. Upon replacing or repositioning the processor, application of additional thermal grease may be necessary.
16. Make sure that the defective MB to be replaced is exactly the same as the replacement MB, inclusive of cables and removable items.
17. Do the reverse when replacing the MB. Please make sure that the same parts are to be installed in the clients unit. Make sure that all screws and cables have been secured and properly returned to their proper places.
10. Check for and remove any Mini PCI Cards installed on the clients unit.
11. Remove the LCD from the motherboard by gently pulling on the LCD pull tab.
Caution: Extra care should be taken when pulling on the LCD pull tabs as they easily be damaged.
12. Remove the screws from the palm rest. The palm rest is normally screwed on to the bottom connected to the base cover or sometimes on top connected to the MB. Gently remove the palm rest by releasing the tabs securing it to the base cover.
Caution: Extra care should be taken when removing the bezel, as excessive force may cause it to crack and break.
13. Remove the CPU fan/Heat sink from the MB by removing the screws & disconnecting the fan cable.
Caution: Gently pull on the plastic connector and not on the wires to prevent damaging the cable. Be sure to place the heat sink so that the portion with thermal grease facing upwards.
