To check the battery pack using software:

Open Power Management in the Windows Control Panel.

2

In Power Meter, make sure that the parameters shown for Current Power 
Source and Total Battery Power Remaining are correct.

3

Repeat the steps 1 and 2, for both battery and adapter. This helps you identify 
first the problem is on recharging or discharging.

To check the battery pack using hardware:

 

1

Turn off the notebook.

2

Remove the battery pack and measure the voltage between battery terminals 
1 (+) and 6 (ground). 

3

If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

If the battery status indicator does not light up, remove the battery pack and let 
it return to room temperature. Re-install the battery pack.

If the charge indicator still does not light up, replace the battery pack. If the charge 
indicator still does not light up, replace the DC/DC charger board.

An audible noise from the power adapter does not always 
indicate a defect.

To check the battery charge operation, use a discharged battery 
pack or a battery pack that has less than 50% of the total power 
remaining when installed in the notebook.
