Just prior to last Christmas you purchased via PC CaseGear a new Asus N53SV SX712V with a twenty four month warranty. Someone accidently tried to put her headphones jack into a Universal Serial Bus port, and that machine just stopped working. A jack was not forced, or stuck and was taken straight out.
What is a process to have it fixed under a warranty? You can try taking out that laptop's battery and also unplugging an AC adapter. Press a power button for sixty seconds to drain any excess electricity buildup.
Plug in that AC adapter and see if it powers on correctly. Once in awhile plugging in devices can cause an electric short. If your still having problems, and your Asus computer is under warranty, then you can browse to this get started with ASUS support web page.
