Need help.
I removed the motherboard from my mac se to replace the clock battery.
upon removal of the motherboard I unplugged the speaker cable.
the cable has room for 2 connections (a + and a - ?), but the
motherboard has 3 pins to recieve the connection of the cable.
I've tried every combination. 1&2 of 3, 2&3 of 3, and reverse 2&1 of
3, and 3&2 of 3. No order of connection of the sound cable to the
motherboard again will make the mac se sound again the startup bong
thru the system speaker. But when I connect a headset to the sound
port I hear it just fine.
As far as I can recall (and it's been a while since I was inside an SE)
the speaker connection on the motherboard is 2 pin. So it may be that
you are trying to plug into the wrong connector. The speaker is not a
polarized component so it doesn't matter, electrically, which way it's
connected.
