Disassembly
Before a technician disassembles a computer, several steps should be performed or considered. The following disassembly tips are helpful:
- Do not remove the motherboard battery, or the configuration information in CMOS will be lost.
- Use proper grounding procedures to prevent ESD damage.
- Keep paper, a pen, a phone, and a digital camera nearby for note taking, diagramming, and photo taking. Even if you have taken apart computers for years, you might find something unique or different inside this one.
- Have ample flat and clean workspace.
- When removing adapters, do not stack the adapters on top of one another.
- If possible, place removed adapters inside a special ESD protective bag.
- Handle each adapter, motherboard, or processor on the side edges. Avoid touching the gold contacts on the bottom of adapters. Sweat, oil, and dirt cause problems.
- Remember that hard drives require careful handling. A very small jolt can cause damage to stored data.
- You can remove a power supply, but do not disassemble a CRT-style monitor or power supply without proper training and tools.
- Document screw and cable locations. Label them if possible.
