adapter cable. See the following figure
1. If the voltage is not correct, replace the power adapter.

K Replace the System board.
K If the problem is not corrected, see “Undetermined Problems” on page 120.
K If the voltage is not correct, go to the next step.

continuity and installation.
4. If the operational charge does not work, see “Check the Battery Pack” on page 105.
