To use the check list you read the problem, then run down the list until you
fix the problem. This is called a fall through check list.
There are two types of power problems.
No power at outlet or no power at mother board.
You go to power up your system and you getnothing.
Probable causes are:
Power cord disconnected
No power at wall outlet or power strip off, may have a blown fuse or has failed.
Power supply has failed.
Steps:
Check power cord pulled loose from computer or electrical socket.
Good?
No power at wall outlet, check socket with another electrical device.
Good?
Power strip off? or has the built in circuit breaker popped?
Good?
(If the power strip circuit breaker is not the problem don't mess with the strip, purchase a
new one,
throw the old one away, cut the power strip power cord off, then someone else can't
use it.)
Still no power?
The following check requires you to open your
computer case.
Trace down the power connection from the power supply to the mother board. Check
the connection to the mother board, disconnect it then reconnect it. Check the other power
connectors to the hard drive and CD ROM.
