● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver) ● Phillips #2 screwdriver ● Diagnostics software ● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper- resistant bits (Smart Cover FailSafe Key, PN 166527-002) Screws The screws used in the computer 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. CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only. CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage. Cables and Connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. 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 in such a way that they cannot be caught or snagged by parts being removed or replaced. CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer. Hard Drives CAUTION: Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares. ● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package "Fragile: Handle With Care." ● Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the CPU. ● Avoid dropping drives from any height onto any surface. ● If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive while the computer is on or in standby mode. ● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.

Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
Phillips #2 screwdriver
Diagnostics software
HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper-
resistant bits (Smart Cover FailSafe Key, PN 166527-002)
Screws
The screws used in the computer 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.
CAUTION:
Metric screws have a black finish. U.S. screws have a silver finish and are used on hard
drives only.
CAUTION:
As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care
to avoid damage. 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 in such a way that they cannot be
caught or snagged by parts being removed or replaced.
CAUTION:
When servicing this computer, ensure that cables are placed in their proper location
during the reassembly process. Improper cable placement can damage the computer.
Hard Drives
CAUTION:
Handle hard drives as delicate, precision components, avoiding all physical shock and
vibration. This applies to failed drives as well as replacement spares.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “Fragile: Handle With Care.”
Do not remove hard drives from the shipping package for storage. Keep hard drives in their
protective packaging until they are actually mounted in the CPU.
Avoid dropping drives from any height onto any surface.
If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive
while the computer is on or in standby mode.
Before handling a drive, ensure that you are discharged of static electricity. While handling a
drive, avoid touching the connector. For more information about preventing electrostatic damage,
