Chapter 4 • Disassembly and Power

Internal Cable Removal

10. Remove all internal cables. WARNING: Do not pull on a cable; use the pull tab, if avail-

able, or use the cable connector to pull out the cable. Some cables have connectors with

locking tabs. Release the locking tabs before you disconnect the cable. Make appropriate

notes regarding the cable connections. Some students find that labeling cables and the

associated connectors makes reassembly easier, but good notes usually suffice.

Adapter Removal

11. Start with the left side of the computer (facing the front of the computer) and locate the

leftmost adapter.

12. Write down any jumpers or switch settings for this adapter. This step may need to be

performed after you remove the board from the computer if the settings are inaccessible.

13. If applicable, remove the screw or retaining bracket that holds the adapter to the case.

Place the screw in a separate, secure location away from the other screws already

removed. Make notes about where the screw goes or any other notes that will help you

when reassembling the computer.

14. Remove the adapter from the computer.

Why must you be careful not to touch the gold contacts at the bottom of each adapter?

15. Remove the remaining adapters in the system by repeating Steps 12–15. Take notes

regarding screw locations, jumpers, switches, and so forth for each adapter.

Drives

16. Remove all power connections to drives, such as hard drives, floppy drives, CD/DVD/BD

drives, and so on. Note the placement of each drive and each cable, as well as any remind-

ers needed for reassembly.

17. Remove any screws holding the drives in place. Make notes about where the screws go.

Keep these screws separate from any previously removed screws.

18. Remove all drives.

Why must you be careful when handling a mechanical hard drive?

What would you do differently when handling an SSD than a SATA hard drive?

Power Supply

19. Before doing this step, ensure that the power cord is removed from the wall outlet and the

computer. Remove the connectors that connect the power supply to the motherboard.

20. Take very good notes here so you will be able to insert the connectors correctly when

reassembling.

21. Remove the power supply.

What is the purpose of the power supply?
