· 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 :
+0V ~ +12.6V
(6 cell)
5
Ground(-)1
Voltage (V dc)Terminal
Note
Charging will take at least 3 hours.
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
Battery is an expendable supplier, so its capacity and used time can be reduced by using the computer.
