AC power

If you have trouble turning on the computer with the AC adaptor connected you should check the status of the DC IN indicator. Please refer to Chapter 6, Power and Power-up Modes for further information.

ProblemProcedure

AC adaptor doesn’t power the computer (DC IN indicator does not glow white)

Check the connections to make sure that the power cord/adaptor is firmly connected to the computer and a working power outlet.

Check the condition of the cord and terminals. If the cord is frayed or damaged it should be replaced, while if the terminals are soiled, they should be cleaned with a clean cotton cloth.

If the AC adaptor still does not power the computer, you should contact your reseller, dealer or service provider.
