Checking the Car-Battery Adapter

Checking the Car-Battery Adapter

NOTE: There are several types of adapters but the checkout procedure is the same for both of them.

Unplug the Car-Battery Adapter cable from the computer.
Plug the Car-Battery Adapter into the cigarette lighter socket.
NOTE: If the adapter is already plugged in, reseat it.
Measure the output voltage of the Car-Battery Adapter cable.

Pin Voltage (Vdc) 1 +19.0 to +21.0 2, 3 Ground
- If the voltage is correct and the power-on indicator on the Car-Battery Adapter is on all the time, the Car-Battery is working correctly. Replace the system board.
  If the problem is not resolved when the system board is replaced, go to 'Undetermined Problems'.
- If the voltage is outside the normal voltage range, do one of the following:
  - Try the above test procedures in a different car, if one is available.
  - Replace the Car-Battery Adapter if the computer works correctly with the AC Adapter.

Pin	Voltage (Vdc)
1	+19.0 to +21.0
2, 3	Ground

NOTE: If the output voltage from the cigarette lighter socket of the car is less than 10.5 Vdc, a continuous noise can be heard. The condition of the car battery should be checked by appropriate service personal.
