The Vanishing PC Speaker

[Glenn Ervin]

Usually pins on the mother board only have a reference number, like J8 or 
some such thing.  I have found that you may need to look up the model of the 
mother board on-line, and get a manual, and the manual will tell you which 
pins are for the speaker.

Most motherboards for any PC will have upright pins for the
speaker.  They're commonly 4 pins, with the two middle pins being
unused.  I wouldn't try it without sighted assistance to read the
writing on the motherboard.  Trying trial and error with some of those
pins could short out the motherboard and fry something important.  The
POST (Power-On Self Test) will always issue beeps to assist in
diagnosing problems, though beep codes vary from one CMOS/BIOS to
another.  Unless PC manufacturers start standardizing front panel
connections, connecting up the cabinet's front panel is about the only
job the blind cannot do to to repair their own systems.
