Headphone jack light turns red when disconnection headphones

The headphone jack has a small switch for audio output. The red light you're seeing means the switch is stuck in the "on" position. You should be able to move it back into place fairly easily. Insert and remove your headphone cord a few times--till the light goes away. You can also try using a toothpick to flip the switch.

Best of luck!

I recently had the same problem, and we used a stripped down Q-Tip with a little of the cotton still left on it. We inserted into the jack, twisted it around, and voila, light went off. I've heard the problem occurs when it's become dirty inside that jack, and you just need to clean it out so your computer no longer thinks your headphones are still plugged in. Way easier than that guy who took his whole computer apart...poor guy.

This was the solution to my problem. I cleaned the jack with the q-tip first. Then inserted and removed the stereo jack and the light went away.

I hope this helps,
