3.First, discharge the battery, until the volta than 10.8V (LiIon) or 9.6V (NiMH). Then, charge battery for 30 minutes. Now, check the voltag voltage is still less than 10.8V (Li-Ion) or 9. replace the battery.

4.If the voltage is more than 10.8V (LiIon) o (NiMH), measure the resistance between batter

minals 5 and 7. The resistance mustΩ (Libe-Ion)390

or 10KΩ (NiMH). If the resistance is not corr replace the Battery ASM. If the resistance replace the DC-DC & BATT board, then the syst board.
