Pins on motherboard disconnected and need to know proper way to reconnect

HP Recommended
HP Pavilion a6430f
Microsoft Windows 10 (32-bit)

While installing an extra harddrive into my system, I believed the pins on the motherboard needed to be modified.  I stupidly did now note their original position and now, although the harddrive is connected, the system will not boot, even though the original harddrive is still connected.  I need to know the proper placement for the pins.

Allow me to welcome you to the HP forums!


Which "pins" are you talking about -- the SATA drive connectors? 


Or, the small pins to which stuff like the drive LED, power LED, power button (etc) are connected?


If it's the SATA drive connectors, then the problem is most likely that when you connect what is the "second" drive to you, the system thinks it is the "first" drive, tries to boot from it -- and fails.


If that is the case, then connect ONLY the original drive and confirm that the system still boots.  It does that because there is only ONE drive to boot from.


If you have multiple SATA drive connectors on the motherboard, and multiple cables, you will have to experiment to determing which SATA cable is for the "first" drive and connect your original drive to that one, and your "second" drive to a different one.

wrong forum, this is the busineness/workstation forum please repost in the Desktop forum



you might also want to include the jumper number (example:  JP14) of the  jumper blocks you changed and if possible take a picture of it and include this or else your chances of a reply is slim


i also recomend you download your models, user and service manuals from HP as they usually cover the jumpers on the motherboard and their location/function
