If removing all power sources except for the backup battery
results in the system being reset, suspect a problem with the
backup batteries. Refer to the following:
1. Enter suspend mode by pressing the Power button.
2. Remove the AAA batteries and measure the voltage
between the battery terminals. The voltage should be
1.1–1.6 V dc per battery.
•
If the voltage is correct, replace the mainboard.
•
If the voltage is less than 1.1 V dc per battery, then
the batteries have been discharged. Replace the
batteries.
•
If the backup battery discharges quickly after
replacement, replace the mainboard.
Note: Make sure either the battery pack is installed or
the AC Adapter is connected. If the backup
batteries are removed and no other power
source is available (AC Adapter or battery pack),
the system is reset, and all the stored data is
lost.
