Dell D620 pc-speaker

If you use this laptop, you probably wonder how to stop the freaking thing - look a bit further for more info:

Windows - Turn Off the PC-Speaker (Annoyances.org) Here you can read how it was a bug in the motherboard :) ... I'd recommend the power-toy solution.

Gentoo Linux - Turn Off the PC-Speaker (Gentoo-wiki) or just "modprobe -r pcspkr" :)
