Checking the Battery Pack (2600-310/310D/310E/310ED)

1.  Power off the computer.
2.  Remove the battery pack and measure the voltage between battery  terminals 1 (+) and 6 (-).

    
   

   Terminal	Voltage (Vdc) / Signal
   1	+0 to +13
   2	ID
   3	Thermal
   4	Data
   5	Reserved
   6	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 +11Vdc, the battery pack has been discharged.  Recharge the battery pack.

    If the voltage is still less than +11Vdc after recharging, replace the battery.
