This light stays solid when the computer is turned on and may blink when the PC is in sleep mode. Pins 2 and 4 (Bottom row, far left side).
A helpful first step is to know what you're working with. The "N15235" marking on the board is actually Foxconn's supplier code, not the model number. This means your board could be one of a few different models:
Note that rather than a specific motherboard model name. Because Foxconn printed this identifier across dozens of layouts from the LGA 775 era up to the LGA 1155 generation, most of these units share Intel's standardized 9-pin system layout, typically designated as F_PANEL or FP1 .

The visual layout of the header follows this configuration:
The small arrow on the connector typically indicates the positive (+) pin. 3. Step-by-Step Connection Guide A. Power Switch (PWR_SW)
Connecting the front panel cables to a motherboard is often the most intimidating part of building or upgrading a PC. The motherboard—a widely used OEM board found in many older budget desktop systems from brands like Acer, HP, and Lenovo—presents a specific challenge. Because it was manufactured primarily for pre-built systems, clear labeling on the board is often missing, and official manuals can be difficult to find. This light stays solid when the computer is
Regardless of which exact model you have, they all share a similar layout for the front panel header.
Turn off the PC, unplug the Power LED and HDD LED connectors, flip them 180 degrees, and plug them back into the exact same pins. The system constantly reboots in a loop
Your reset switch or power switch might be shorting against an adjacent pin, or your motherboard stands are causing a short circuit behind the board. Ensure all front panel cables are cleanly separated. The "N15235" marking on the board is actually
HDD LED, HDD LED, PWR LED, PWR LED, (Blank/No Pin)
These connectors are usually located on the motherboard's front panel header, which is typically situated at the front of the computer case.
This is the most finicky connection on the Foxconn N15235. Modern cases use a 2-pin POWER LED connector. Insert it so that (bottom row, first pin from left) and negative (-) goes to Pin 4 (bottom row, second pin from left). If your case has a 3-pin Power LED with a blank middle, plug it so the blank sits over Pin 3 (top row, second pin).
