Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then
clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep
inside the display or stain the bezel.
MSR maintenance
To clean the MSR (magnetic strip reader), swipe a standard cleaning card through the MSR a couple of times.
You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and software requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
Phillips #2 screwdriver
●
Phillips #1 screwdriver
●
Diagnostics software
●
Tamper-resistant T-10 screwdriver
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:
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.
Lithium coin cell battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime
of about three years.
