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.
