Do NOT remove components while the computer is powered up!
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.
