procedures: Small Form Factor (SFF)

Adherence to the procedures and precautions described in this chapter is essential for proper service.

After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify

that all components operate properly.

NOTE: Not all features listed in this guide are available on all computers.

Preparation for disassembly

See Routine care, SATA drive guidelines, and disassembly preparation on page 35 for initial safety

procedures.

1. Remove/disengage any security devices that prohibit opening the computer.

2. Remove all removable media, such as compact discs or USB flash drives, from the computer.

3. Turn off the computer properly through the operating system, then turn off any external devices.

4. Disconnect the power cord from the power outlet and disconnect any external devices.

CAUTION: Turn off the computer before disconnecting any cables.

Regardless of the power-on state, voltage is always present on the system board as long as the

system is plugged into an active AC outlet. In some systems the cooling fan is on even when the

computer is in the “Standby,” or “Suspend” modes. The power cord should always be

disconnected before servicing a unit.

5. If the computer is on a stand, remove the computer from the stand and lay the computer down.

NOTE: During disassembly, label each cable as you remove it, noting its position and routing.

Keep all screws with the units removed.
