If your computer does not power on with the AC adapter connected, this would indicate a problem with the AC adapter, or with the DC jack on the computer itself. If you are sure the AC adapter is functioning properly, then the problem would be with the DC jack, and the computer would require service. If your computer requires service, please contact Acer Technical support to set up repair.
