1.Power off the computer.

2.Remove the battery pack and measure the voltage between battery terminals 1

(+) and 7 (−). See the following figure:

7(-)

Terminal Voltage (V dc)

3 4 5

1(+) 2(+)

6(-)

1	+ 0 to + 12.6
7	Ground (−)

3.If the voltage is less than +11.0 V dc, the battery pack has been discharged.

Note: Recharging will take at least 3 hours, even if the indicator does not turn on.

If the voltage is still less than +11.0 V dc after recharging, replace the battery.

4.If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 4 and 7. The resistance must be 4 to 30 K .

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