HP DX5150, MS-7050 v. 1.3 Motherboard front panel pin connectors

Question

I recently purchased and installed a MS-7050 v. 1.3 motherboard into a regular non-HP case and thus the front panel connectors are different than the original OEM connectors which are all bundled together. The HP support website does not have this information available and someone from HP indicated in response to a support forum question that this information is not available.

What is the motherboard pin schematic for the front panel i/o connectors (power, reset, hdd led, and power led)?

Answer 2

I spent a long time tracking down the info on the headers for the MS-7050 motherboard. It's an OEM version exclusively used in the HP DX5150 desktop (SFF) and mini-tower PCs, so there is no information on it from the MSI website. To help others find this more easily, I've posted it online and also made it available as a PDF here: http://homepage.ntlworld.com/loz-saunders/MS-7050/

Hope this helps someone.
