: Connect the positive wire ( PLED+ ) to Pin 2 and the negative wire ( PLED- ) to Pin 4 .
If you are connecting a standard case, follow this guide to mapping your front panel wires to the IPISB-VR board:
The header has : Row 1 (Pins 1-5) and Row 2 (Pins 6-9, missing pin 10).

. Because this board is often found in OEM systems like the Gateway DX4860, it lacks a standard retail manual, but the pinout follows a specific layout.

The number one complaint about the is: “I connected everything, but the PC won’t turn on.”

One of the biggest frustrations for owners of this motherboard is the complete lack of an official pinout diagram. Without this, even a simple case swap can become a challenging puzzle.
Unlike retail motherboards from ASUS or MSI, OEM motherboards like the Acer IPISB-VR use proprietary, unlabelled front panel connectors. Connecting these pins incorrectly can prevent your computer from turning on, cause the status lights to malfunction, or cause short circuits.
To rule out a broken case button, gently touch a flathead screwdriver blade across Pin 6 and Pin 8 for one second. If the system boots up, your motherboard is fine, but your front panel switch or wiring is faulty. The Power or HDD Lights Do Not Blink Use this quick reference to identify the wires
Keep this article bookmarked or print the pinout table above. Tape it inside your PC case for future reference. With the correct wiring, your Acer motherboard will behave just like any standard board—giving new life to an old system.
Unlike standard retail motherboards that follow Intel’s Front Panel I/O Connectivity Design Guide, Acer uses a proprietary pinout. Plugging a standard PC case’s power switch into this board without a diagram can lead to a system that refuses to boot—or worse, shorted LEDs.
: For LEDs (HDD and Power), the colored wire is typically positive (+), and the black or white wire is negative (-). If the LED doesn't light up, simply flip the connector.
If you are upgrading your case, repairing a broken button, or swapping the motherboard into a new chassis, you will likely encounter a 14-pin or 16-pin non-standard header.
After reverse-engineering Acer’s proprietary schematics and testing with a multimeter, here is the definitive pinout for the front panel header.
