Checking the Battery Pack (2635-380/385)

Checking the AC Adapter (2635-380/385)
  1.  Power off the computer
  2.  Remove the battery pack and measure the voltage between  battery terminals 1 (+) and 4 (-).


    Terminal Voltage (Vdc) / Signal
    1 +0 to +13.5
    2 N/C
    3 Thermal
    4 Ground (-)
    5 Select
    6 A-Ground


    NOTE: Signal lines not used in these steps are used for  communication between the system and the battery.

  3.  If the voltage is less than +11.0 Vdc, the battery pack has been discharged.  Recharge the battery pack.
     If the voltage is still less than +11.0 Vdc after recharging, replace the battery.

    NOTE: If the voltage of the battery pack is 0 V, it is not defective.

  4.  If the voltage is more than +11.0 Vdc, measure the resistance between battery terminals  3 and 4. The resistance must be 4 to 30 K ohm.
     If the resistance is not correct, replace the battery pack.
     If the resistance is correct, replace the subcard.
