ASSEMBLY-DISASSEMBLY    - always follow safe installation procedures to avoid accidents and computer hardware failures.

Before you start working, make sure that all cables are disconnected and that none of your computer hardware are plugged to a power source. Plugged equipment can convey electrical charges and you may get a shock while you tinker around you’re your internal computer components.

In addition, wear a grounding wrist strap before you attempt to touch any internal computer hardware. Grounding wrist straps protect your PC parts from electrostatic electricity. While not harmful to humans, electrostatic electricity can easily damage and short-circuit your desktop computer motherboard and other sensitive computer components.

If you do not have a grounding wrist strap, touch a grounded metal object every so often while you work. This can release any build-up of static electricity on your hands.

When you are already removing the computer components attached to your old PC motherboard, be very gentle. Never try to force anything out or fit anything in for that matter. If you are having difficulty removing a particular computer hardware, check to see if it is held in place by screws or bolts. Video cards can be screwed onto the motherboard to prevent their accidental removal. And when screwing bolts, do not tighten them too much. This can crack your desktop computer motherboard.

To save you some hassle, do not close your computer case once everything is set up. Try booting up your PC first to check whether all your internal computer components are properly fitted together. If your computer works normally, then you can seal the case and start enjoying your new PC motherboard.

There are certain procedures you should follow when you are installing items in your system. Below is information to avoid damage to your system or/and yourself.

    * Before entering the computer, move computer off the carpet (for static purposes). If your not able to then try not to move on the carpet to keep the static from building.* Disconnect all cables including power cord. Remove the power cord, monitor, keyboard, mouse, phone line, network cable, speakers, printer, scanner, USB cables, cable modem, DSL modem and anything else that is connected.* With everything disconnected, push the power button for 5 seconds. (with power

cord disconnected). The computer can store power even with the power cord disconnected. Pushing the power button drains that power (only if the power cord is disconnected). VERY IMPORTANT!!!* Touch something metal on the case of the system to release any static build up in your body.* Computers are the best dust collectors. Do not blow on the dust with your breath. Your breath has moisture and electronics hate moisture.* If you want to clean the inside of the system of dust, use compressed air that is designed for electronics.* While using the compressed air, do not hold down the button. Not only will the can get cold, moisture will also form. Use quick short bursts.* When handling parts, do not touch the bronze teeth. Hold the parts on the edges if at all possible.* If you are troubleshooting noise issue, some people will stick a pencil or other objects in the fan to stop the fan from turning to see if the noise goes away. DON'T DO THAT! The fan might shatter the pencil, cause a fire, cause electrical shock or short.* If you disconnect the cable that goes to the processor fan to check for noise, do not leave system on for long with it disconnected.* Be careful while inside system, the system has sharp edges.* Never put your hands inside system when the system is either plugged in or turned on.* Some computer desks have a compartment that you can put your computer in. Make sure that compartment is well ventilated. If it is not ventilated, it can fry the system. If it is not well ventilated, you can drill holes in the desk to give it ventilation, or you can install a small fan in the desk that will circulate air.* Do not connect or disconnect cables while the system or device is turned on. (unless it is USB. USB can be disconnected or connected while system is on). Equipment can be damaged by this.

VERY IMPORTANT NOTEIf you have access to your personal files, make sure they are backed up before tinkering with the system. Sometimes there can be more than one issue and one of the issues may not show till you start tinkering with the system. For example, I have seen a hard drive be bad but it works as long as the system is on. However when you turn the system off, the hard drive doesn't work anymore. Once that happens, you can't get access to your files.

ΔЅịMø: OCCUPATIONAL HEALTH AND SAFETY PROCEDURES 

-   Always ground or discharge yourself before touching any part of the computer-   Do not work alone so that there’s someone who can take care of you in case of accident or emergency. -   Be careful with the tools that may cause short circuit-   Always full the cable connector on the handle and not on the cable itself-   Use only rubber shoes when standing on the ground or in a concrete floor-   Make sure that the pins are properly aligned when connecting a cable connector.-   Always power off and unplug the computer before working on it.-   Take away any liquid such as mineral water or soft drinks near your working area or near computers.-   Contingency measures during workplace accidents, fire and other emergencies are recognized.-   Personal protective equipment is correctly used in accordance with organization OHS procedures and practice.-   Hazard/risks in the workplace and their corresponding indicators are identified to minimize or eliminate risk to co-workers,         workplace and environment.-   Take necessary precautions to protect the component of the computer from damaged cause by Electrostatic Discharge (ESD).-   Hold the components by edges and do not touch the IC’s.-   Read and follow instruction on the manual carefully.-   Do not use excessive force if things don’t quite slip into place.

GUIDELINES FOR DISASSEMBLING A COMPUTER

1. Determine the control panel configuration(color coding, polarity, labels, USB).2. Remove all the cables(Data Cables, Power Cables)3. Remove all the components(HDD, FDD, CD-ROM, and Expansion Cards)4. Remove the power supply or the motherboard(it depends in your system unit case whether the power supply or the motherboard     disassemble first, because some system unit case should disassemble first either the power supply or motherboard in order to take     out the other).5. Remove the memory and the microprocessor.

FOR ASSEMBLING: just do the guidelines reverse(step 5-1).Note: Always take in mind the 5's in the whole assembly-disassembly assessment. Because the assessor are watching you while you are doing the assessment.

5'S

1. SORT(SURIIN) - take out unnecessary items and dispose2. SYSTEMATIZE(SINUPIN) - arrange necessary items in good order.3. SWEEP(SIMUTIN) - clean your workplace4. SANITIZE(SIGURADUHIN ANG KALINISAN) - maintain high standard of housekeeping5. SELF-DISCIPLINE(SARILING-KUSA) - do things spontaneously without being told or ordered
