ACER T690 "where does the sd card reader cable attach to the motherboard?
Motherboard installed in computer case, look at the bottom edge of the motherboard.
Now I need your eyes
Underneath that long white PCI slot at the Bottom, (There are 2),
is a Purple rectangular header. Two rows of pins.
To the right is another rectangular header, but this time in Blue.
Look below them on the motherboard. Towards the outside edge of the motherboard. Do you see USB next to either of them?
The Card Reader just attaches to a USB header. The rectangular header actually supports TWO USB ports.
This is why one of those headers may have two USB cables hooked to it, and go to two separate USB ports on the Front Panel of the computer.
The other USB header would be for the Card Reader.
Looking even more to the right, there are two Yellow headers, that I'm SURE are USB headers. Looks like one long header, but it isn't.
I COULD be mistaken about the Purple header, or Blue header.
One might be for IR Remote.
At any rate, again, I need your eyes. What is silkscreened on the motherboard, under those headers? Purple, Blue, and Yellow?
Unless just one plug connector, is unplugged from one of those headers. (Two cables go to Card Reader, and end in one plug connector, that plugs into the motherboard)
Then you would know by the process of simple elimination.
Note how in the two rows of pins, there is one missing in the corner.
5 pins on one side, 4 pins on the other side.
The missing pin is the KEY. That is how you orient the plug connector.
