Static noise from under keyboard

I got a new MacBookPro.

After 2 months, I started hearing static noise from the left speaker/keyboard area after booting up. It is an intermittant problem.

I have since discovered that removing the AC power cord has no affect on the noise. Turning off the speaker has no affect on the noise. Also inserting headphones into the jack has no affect on the noise.

Any ideas?

Also, when I looked inside the headphone jack hole, i see a red LED lit in there. Whats that?

No idea what could be causing the static noise but since the machine is still under warranty, take it in to Apple and have them look at it. Whatever is causing that sound might also be causing damage to the machine.

Regards.
