Install a good battery and make sure the LED lights up orange while the AC adapter is
connected. When the LED does not light up or blinks, check the connection of the

the harness has been connected firmly, replace the main board.

For this check, use a battery which is not fully charged (because the LED does
not light when the battery is fully charged.)
Before this check, make sure other function work correctly.
