1.12.4.2 Factory Test only
The Factory Tests are provided for factory personnel only and should not be performed by
customers. This test requires special production test hardware and will fail without the proper
equipment.
NOTE: Remove the test kit connector from the Messenger during factory test kit validation
tests to prevent false results and to prevent test signals from being injected into the Messenger.
1.13 Long-term maintenance
The following preventative maintenance is recommended for the long-term care of your test kit.
•
Keep the system in a cool, dry, and dust-free environment.
•
Power ON the system at least once every 3 months to recharge the CMOS battery.
•
Make sure the system is OFF whenever it is shifted from one place to another.
1.13.1 Motherboard battery maintenance
The CMOS or Complementary Metal Oxide Semiconductor battery is an on-board
semiconductor chip. This chip is used to store system information and configuration settings
while the computer is off and on.
Lifetime: The standard lifetime of a CMOS battery is around 10 Years, however this amount of
time can change depending on the use and environment that the computer resides.
Detection: A Low battery can be detected by checking the time stamping of test results. See
Troubleshooting on page 60 for help diagnosing the issues.
Corrective action
•
Replace the CMOS battery. Follow the manufacturer’s instructions for proper battery
disposal.
•
Make sure that the polarity of the battery is right before inserting inside the slot.
•
Reload the saved CMOS Setup Details. (There are no special settings for the System Test Kit,
so this step can be skipped.)
