Foxconn N15235 Front Panel Connectors - Google Site
Before we dive into the wiring, let's define the hardware. The "Front Panel Connectors" (often labeled F_PANEL or FP1 on the board) are a block of 9 to 14 pins located on the bottom-right corner of the Foxconn N15235 motherboard.
These pins control five critical functions of your computer case:
The Problem: On a standard motherboard, the power switch is usually pins 6 and 8. On the Foxconn N15235, the layout is shifted. If you plug your case wires in using the "standard" layout, your PC will not turn on.
On the board (usually near the bottom edge, close to the PCI slots), you’ll find a rectangular block of 16 pins in two rows of 8. The pinout is not documented in a typical user manual. Through hours of community forum digging and multimeter testing, here is the verified pinout (looking at the board with the PCI slots to your left): Foxconn N15235 Front Panel Connectors - Google
Top Row (Pins 1-8, left to right):
Bottom Row (Pins 9-16, left to right): 9. Ground 10. Ground 11. Speaker (+) 12. Speaker (-) 13. Reset Button (+) 14. Reset Button (-) 15. Key / No pin (sometimes missing) 16. Ground
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. Before we dive into the wiring, let's define the hardware
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.
Look at the very bottom right corner of your motherboard. You are looking for a block of 9 pins arranged in two rows (Row of 5, Row of 4). The 10th pin is missing to prevent you from plugging it in upside down.
Here is the exact layout:
[TOP ROW - Pins 1 to 5] +---+---+---+---+---+ | | | | | | |PLED|PLED|PWR|PWR| (Empty/NC) | + | - | SW| SW| 5 +---+---+---+---+---+
[BOTTOM ROW - Pins 6 to 9] +---+---+---+---+ | | | | | |HDD|HDD|RES|RES| |LED+|LED-|SW |SW | +---+---+---+---+
