Locate the connector (sometimes split into two single-pin headers). Connect the positive lead to Pin 2 and the negative lead to Pin 4 on the top row, directly to the left of the power switch. 5. Connect the HDD LED (Pins 1 and 3)
Now, use the map above to connect your case's front panel connectors, which are typically small, two-pin plugs. acer ipisb-vr rev 1.01 front panel

The pins are arranged in two rows. Row 1 (Odd) is typically closer to the center of the board, and Row 2 (Even) is closer to the edge.

The Acer IPISB-VR (often found in models like the Aspire M3910, M3970, and Veriton series) utilizes a proprietary motherboard design standard often referred to as the "Davo" or "Pegatron" form factor. While the board functions like any standard PC motherboard, the front panel header (JFP1) presents a specific challenge for users attempting to transplant the board into a non-Acer case or repair a system with damaged front panel wires. Unlike industry-standard ATX boards that use a widely adopted pinout, Acer frequently customizes the voltage and ground layout on this specific revision.
After reverse-engineering Acer’s proprietary schematics and testing with a multimeter, here is the definitive pinout for the front panel header.
Flip the orientation of the LED plug. For example, if your HDD LED is on pins 1 and 3, pull the plug out, rotate it 180 degrees, and push it back onto the same pins. The Fans Spin for One Second then Shut Down
Ensure you did not shift the connectors over by one pin vertically or horizontally. Connect the positive lead to Pin 2 and
Usually the row closer to the edge of the motherboard.
