If you’re reading this, chances are you’ve just inherited an old pre-built PC (perhaps an HP Pavilion or a Compaq Presario) or you’re trying to resurrect a board pulled from a defunct machine. The motherboard in question? The Foxconn N15235.
This board is a classic OEM workhorse. It isn’t flashy, but it gets the job done. However, there is one universal frustration that stops every build dead in its tracks: The Front Panel Header.
If you don’t have the specific OEM manual (HP/Compaq rarely included one with the retail box), hooking up the Power SW, Reset SW, HDD LED, and Power LED becomes a frustrating game of guesswork. Let’s solve that right now. Foxconn N15235 Front Panel Connectors - Google
This is the section you came for. After cross-referencing OEM service manuals from HP (Compaq SG3 series) and direct hardware probing, here is the verified pin layout.
Assume you are looking at the motherboard with the PCIe slots facing left and the I/O ports (USB, Ethernet) facing up. The front panel header is at the bottom right. If you’re reading this, chances are you’ve just
Look for an empty slot in the pin grid (Pin 9 or Pin 10 missing). This is your orientation anchor. The top row is usually "odd" numbers (1,3,5,7,9) and the bottom row is "even" (2,4,6,8).
In a perfect world, every motherboard uses the Intel standard pinout (two rows of 5 pins with one missing key pin). The Foxconn N15235 mostly follows this, but because this board was used across multiple chassis (HP, eMachines, Gateway), the color-coding of the wires may vary wildly. This board is a classic OEM workhorse
Warning: Do not trust the wire color alone! Always assume red is positive (+), but sometimes manufacturers swap them. Use the pinout diagram below as your source of truth.
