So, here's where I am.
I took a look at this video
https://youtu.be/uglCm_qsojkThen I did what the video said.
I hooked the ground to pin 25 and then the positive on the multimeter to pin 2. It was reading 3.3V
I checked pin3 and it read zero. Then I pushed the up and down arrow and the output changed to 3.3V
I checked pin 4 and it was zero. I used the page up and page down and the pin read 3.3v.
The interesting part was that, once the pin went high (3.3v) it wouldn't go low again.
Still trying to figure out why X will work, though.
I only tested pins 2,3,4 this way. If they don't go low then there appears to be a problem in the computer.
