·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
5(+) 4 3 2
Terminal | Voltage (V dc) | |

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.
