Disassembly Procedures
The computer has two basic types of cable connectors:
?
Pressure Plate Connectors
?
Coaxial Cable Connectors
?
Normal Pin Connectors
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector’s plastic
pressure plate and slide the cable out of the connector. To connect the cable to a Pressure Plate
connector, make sure the pressure plate is fully lifted and slide the cable into the connector. Secure
the cable in place by pushing the sides of the pressure plate down so the plate is flush with the sides
of the connector. Gently pull on the cable to make sure the cable is secure. If you pull out the
connector, connect it again making sure the connector’s pressure plate is fully lifted when you insert
the cable.
Coaxial cables should be disconnected with an antenna coaxial disconnector.
Standard pin connectors are used with all other cables. These connectors can be connected and
disconnected by simply pulling them apart or pushing them together.
