Service considerations
Keep these considerations in mind during the disassembly and assembly of the computer.
Tools and software requirements
To service the computer, you need the following tools:
● Torx T-15 screwdriver
● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
● Phillips P1 screwdriver
● Non-conductive, non-marking pry tool
● Diagnostics software
Screws
The screws used in the computer are not interchangeable. They could have standard or metric threads and
may be of dierent lengths. If an incorrect screw is used during the reassembly process, it can damage the
unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was
removed and then returned to their proper locations.
IMPORTANT: As you remove each subassembly from the computer, place it away from the work area to
prevent damage.
Cables and connectors
Apply only the tension required to seat or unseat the cables during insertion or removal from the connector.
Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and
ensure that the cables are routed so that they cannot be caught or snagged by parts being removed or
replaced.
