When disassembling the system, follow these general rules.
!
Turn off the system and unplug the AC power cord.
! Disconnect all peripherals before disassembling the system.
!
Before opening the system or handling boards or chips, touch the frame to discharge static.
!
Do not disassemble parts other than those specified in the procedure.
!
The system uses several types of screws. Be sure to note the type of screw being removed.
Use the same type when assembling the system.
!
Label any connector before disconnecting it. Note where the connector goes and in what
position it was installed.
! Use care in disconnecting cables. To prevent cable breakage, pull only on the connector. Do
not pull on the cable.
!
When installing a cable, route the cable so it is not pinched by other components and is out
of the path of the cover.
