Unfortunately I'm not familiar with this specific laptop line though I did find a link to the parts listing: https://www.manualslib.com/manual/273186/Hp-Compaq-Presario-Presario-1200.html?page=3#manual . That only lists potential drive spares, though that might be of use when trying to track down a pinout. Sorry I couldn't have been of more help. -Henry
