Having just put together my new system, I needed to use the floppy drive from my HP 8600 series computer. In order to access the mobo and drive bay, I had to remove the case fan and power supply. Anyways, now when I try to boot up my old HP, the power supply doesn't work. I know it's one of two things: 1) I slightly chaffed a wire when sliding the drive bay in and out - I quickly noticed the chaffe and wrapped the wiring in electrical tape. 2) There is a loose connector - labeled as P8. It's a 4 pin connector but for the life of me, I cannot find it's home on the mobo. There is a connector labeled P9 that is seated but Im lost with the P8. HP customer support has expired and they want me to "pay" for it. Screw them. Any ideas?
