Hello
\015\012
\015\012Have you tried another keyboard? What troubles me is you said that lights blink when you unplug and replug it in. This jack was never intened to be hot swappable (meaning plug and unplug with power on. I hope the only thing wrong is the keyboard else you'll need a serviceperson to diagnose the motherboard.
