ESD

You need to remember that Electricity will destroy delicate components. This is called Electromagnetic Static Discharge (ESD), static electricity. You can build up enough static electricity to damage a unprotected part by walking across the room. How do you discharge the static electricity? By grounding yourself, you can buy a static wrist strap at your local electronics store or online. You connect the alligator clip to the case of computer, the power is unplugged so it is not grounded but the case will absorb any static electricity you have built up by walking around.

Remove all JEWELRY!

A checklist of probable no power:

House power on? check

Power at the receptacle? check (the lamp next to the computer is on right?)

Unplugged and plugged in the power cable to both the wall receptacle and the computer power supply? Check

Tools:

Tools you may need to open your case and remove components:

Some of the newer computers do not need tools to get components out, they are secured by spring loaded devices (latches).

You will need either a # 2 Philips screw driver or a # 15 torque to remove the screws.
