Check the Power Adaptor

Unplug the power adaptor cable from the computer and measure the output voltage at the plug of the power adaptor cable. See the illustration and follow the procedures below.

  1. If the voltage is not correct, replace the power adaptor.
  2. If the voltage is within the range:
  • 1) Replace the system board.
  • 2) If the problem is still not resolved, see "Undetermined Problems".
  • 3) If the voltage is not correct, go to the next step.

NOTE: An audible noise from the power adaptor does not always indicate a defect.

  1. If the power-on indicator does not light up, check the power cord of the power adaptor for continuity and correct installation.
  2. If the operational charge does not work, see "Check the Battery Pack".
