The Laboratorium : Baby Steps, Baby Steps

In search of the annoying buzzing sound emanating from my computer here at work (which sound I could generally cause to go away briefly by whanging the side of the computer with the heel of my hand) I took the cover off and searched for the offending part. Turned out to be the internal speaker, of all things, wedged between the power supply and the vent and vibrating entire, causing its plastic sheath to rattle against the metal walls of its cage. Sedatives were administered, and all is blissfully quiet now.
