Motherboard

22. Make note of any motherboard switches or jumpers and indicate whether the switch

position is on or off.

What is the importance of documenting switches and jumpers on the motherboard?

23. Remove any remaining connectors except those that connect a battery to the mother-

board. Take appropriate notes.

24. Remove any screws that hold the motherboard to the case. Place these screws in a differ-

ent location from the other screws removed from the system. Write any notes pertaining

to the motherboard screws. Look for retaining clips or tabs that hold the motherboard

into the case.

25. Remove the motherboard. Make notes pertaining to the motherboard removal. The com-

Reassembly

26. Reassemble the computer by reversing the steps for disassembly. Pay particular attention

to cable orientation when reinstalling cables. Before reconnecting a cable, ensure that

the cable and the connectors are correctly oriented and aligned before pushing the cable

firmly in place. Refer to your notes. The first step is to install the motherboard in the

computer case and reconnect all motherboard connections and screws.

27. Install the power supply by attaching all screws that hold the power supply in the case.

Reattach the power connectors to the motherboard. Refer to your notes.

28. Install all drives by attaching screws, cables, and power connectors. Refer to your notes.

Attach any cables that connect the drive to the motherboard.

29. Install all adapters. Attach all cables from the adapter to the connecting device. Replace

any retaining clips or screws that hold adapters in place. Refer to your previous notes and

diagrams.

30. Connect any external connectors to the computer. Refer to previously made notes, when

necessary.

31. Replace the computer cover. Ensure that slot covers are replaced and that the drives and

the front cover are aligned properly. Ensure that all covers are installed properly.

32. Reinstall the computer power cable.

33. Once the computer is reassembled, power on all external peripherals and the computer. A

chassis intrusion error message may appear. This is just an indication that the cover was

removed.

Did the computer power on with POST error codes? If so, recheck all diagrams, switches,

and cabling. Also, check a similar computer model that still works to see if you made

a diagramming error. A chapter on logical troubleshooting comes next in the book.

However, at this point in the course, the most likely problem is with a cable connection or

with an adapter not seated properly in its socket.
