If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.

Checking the battery pack

Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life.

To check the status of your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon.

Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it.

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:

1(+) 2

5(-)

Terminal Voltage (V dc)

1

+ 0 to + 16.8

 

 

5

Ground (−)

3.If the voltage is less than +14.4 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 +14.4 V dc after recharging, replace the battery.

4.If the voltage is more than +14.4 V dc, measure the resistance between battery terminals 4 and 5. 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.
