·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 1(-) and 5(+). See the following figure :

5(+) 4 3 2 1(-)

Terminal

Voltage (V dc)

 

 

1

Ground(-)

 

 

5

+0V ~ +12.6V

(6 cell)

 

 

 

3.If the voltage is still less than +11.1 V DC after recharging, replace the battery.

4.If the voltage is more than +11.1 V DC, measure the resistance between battery terminals 1 and 2. The resistance must be 2 to 4 (typically 3 ).

5.If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

Note

Charging will take at least 3 hours.

Note

Battery is an expendable supplier, so its capacity and used time can be reduced by using the computer.
