I turned on the power, but the computer does not start or boot up.

Look at the power indicator:

•If it is not lit, no power is being supplied to the computer. Check the following:

•Make sure that the AC adapter is properly plugged into the computer and to the power outlet.

•If it is lit, check the following:
