Identifying the Chassis, Routine Care, and Disassembly Preparation
4.4 Service
Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly
and assembly of the workstation.
4.4.1 Power Supply Fan
The power supply fan is a variable-speed fan based on the temperature in the power supply.
Ä
CAUTION:
The cooling fan is off
only
when the workstation is turned off or the power cable has been
disconnected.
The cooling fan is always on when the workstation is either in the “On,” “Standby,” or “Suspend” modes.
You must disconnect the power cord from the power source before opening the workstation to prevent
system board or component damage.
4.4.2 Tools and Software Requirements
To service the workstation, you need the following:
■
Torx T-15 screwdriver (Compaq screwdriver with bits, PN 161946-001)
■
Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)
■
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
■
Diagnostics software
■
Compaq tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or
Compaq tamper-resistant bits (Smart Cover FailSafe Key, PN 166527-002)
4.4.3 Screws
The screws used in the workstation are not interchangeable. They may have standard or metric
threads and may be of different 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, then returned to their proper locations.
✎
Metric screws have a black finish.
U.S. screws have a silver finish.
✎
As each subassembly is removed from the workstation, it should be placed away from the work
area to prevent damage.
