Checking the Battery Pack

Checking the Battery Pack

To check the battery pack, do the following:

1.  Power off the computer.
2.  Remove the battery pack and measure the voltage between battery terminals 2(+) and 7(-).  See the following figure:
    
   

   Terminal	Signal / Voltage (Vdc)
   1	Sense
   2	Power ( > 8 Vdc)
   3	Reserved
   4	Reserved
   5	Thermal
   6	Sense
   7	Ground

    

   Note: Signal lines, not used in these steps, are used  for communications between the system and the battery.

3.  If the voltage is less than +8 Vdc, the battery pack.
    If the voltage is still less than +8 Vdc after recharging, replace the battery.
