Acer Ipisb-vr Rev 1.01 Front Panel Instant
Introduction 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.
Physical Layout The front panel connector on the IPISB-VR Rev 1.01 is typically located on the bottom-right edge of the board, situated between the SATA ports and the board edge. It generally consists of a single block header with roughly 10 to 14 pins, though not all pins are populated.
The connector is designed to accept a single plastic housing block (often colored blue or black on the stock Acer chassis wire harness) rather than individual separated pins (the "dupont" style found on aftermarket cases).
The Pinout Configuration (Rev 1.01 Specifics) Note: Pinout diagrams for Acer boards vary slightly by manufacturing date. Always verify with a multimeter if possible.
On the IPISB-VR Rev 1.01, the header is usually read from left to right, with the bottom row typically handling the critical power and ground signals. The most common configuration for this revision is as follows:
Bottom Row (closest to the board edge):
Top Row (inner row):
Key Differences from Standard ATX: On a standard generic motherboard, the Power Switch and Reset Switch pins are usually separated by a ground pin. On the IPISB-VR, Acer often groups the Power Switch pins adjacent to each other (e.g., Pins 4 and 5). If you connect a standard case cable following the "Ground-Power-Reset" generic text label, you will likely short the system or fail to power it on.
The Polarity Challenge
Hardware Integration Warning A major consideration for the IPISB-VR is the lack of a standard Reset Button on many Acer chassis configurations. While the motherboard header often has pads for a reset function, the stock front panel bezel on many Acer cases omits the physical button. If you are moving this board into a gaming case, you can connect the Reset switch, but consult the board silk-screening; some revisions utilize the reset pin location for "Wake on LAN" or proprietary fan speed signaling instead.
Conclusion The IPISB-VR Rev 1.01 is a robust OEM board, but its front panel header requires a non-standard wiring approach. Successful integration requires ignoring the generic "ATX Pinout" charts and treating the connector as a proprietary interface, specifically noting the adjacent Power Switch pins and the specific LED polarity. If connecting to a standard case, it is often easier to cut the individual 2-pin headers off the new case's wires and insert them into the Acer block one by one, rather than trying to force the entire block onto the pins incorrectly.
Connecting the front panel of the Acer IPISB-VR Rev 1.01
(often found in the Acer Predator G3610 or Gateway DX4860) can be tricky because the motherboard lacks clear on-board silk-screening. Front Panel Header Pinout acer ipisb-vr rev 1.01 front panel
The header is typically a 14-pin or 15-pin block. Pin 1 is identified by a white square printed on the motherboard's corner. Pin Numbers 1 (+) & 3 (-) HDD LED Indicates hard drive activity; polarity matters. 2 (+) & 4 (-) Power LED Lights up when the PC is on; polarity matters. 5 & 7 Reset Switch Restarts the PC; polarity does not matter. 6 & 8 Power Switch Turns the PC on/off; polarity does not matter. 10 No Pin Used as a "key" for orientation. 12 (+) & 14 (-) LAN LED
Indicates network activity; often unused in aftermarket cases. Pin Layout Visualization
Pins are arranged in two rows. The odd-numbered row (1, 3, 5, 7...) is closer to the center of the motherboard, while the even-numbered row (2, 4, 6, 8...) is closer to the motherboard's edge.

Identify Polarity: For LED connectors, the positive (+) wire is usually colored (red, green, or blue), while the negative (-) wire is typically white or black. You can also look for a small arrow symbol on the back of the plastic connector, which indicates the positive side.
Case Swap Difficulty: If you are moving this motherboard to a new case, the standard individual 2-pin connectors from the new case must be plugged in vertically (e.g., bridging pins 1 and 3) according to the diagram above.
Safety Check: If the PC won't turn on, ensure the Power Switch is on pins 6 and 8. You can briefly bridge these two pins with a screwdriver to test if the board powers up without the case button.

Bottom line: The front panel header is proprietary, poorly documented, and lacks standard reset/HDD LED options. Fine for OEM use, frustrating for modding. Introduction The Acer IPISB-VR (often found in models

Here is the full story behind the Acer IPISB-VR Rev 1.01 motherboard, specifically focusing on the infamous Front Panel connection issue.
This is one of the most common "repair horror stories" in the PC building world. It is a tale of proprietary design, missing manuals, and a wiring puzzle that has confused thousands of users trying to revive old Acer computers.
Here is the correct mapping for the 9 pins:
| Pin # | Signal Name | Function | Wire Color (Typical) |
| :--- | :--- | :--- | :--- |
| Row 1, Pin 1 | PLED+ | Power LED Positive | Green or White |
| Row 1, Pin 2 | PLED- | Power LED Negative | White or Black |
| Row 1, Pin 3 | PWR_SW | Power Switch (Positive) | Orange or Blue |
| Row 1, Pin 4 | PWR_SW | Power Switch (Negative/Ground) | White or Black |
| Row 1, Pin 5 | RESET | Reset Switch | Red or Blue |
| Row 2, Pin 1 | HDD+ | HDD LED Positive | Red or White |
| Row 2, Pin 2 | HDD- | HDD LED Negative | White or Black |
| Row 2, Pin 3 | GND | Ground for Reset Switch | N/A |
| Row 2, Pin 4 | GND | Ground for Power Switch | N/A |
| Pin 5 (Row 2) | (Missing) | Key (No pin) | N/A |
| Pin 6 (Row 2) | +5V_DUAL | 5V Standby (Not typically used for front panel) | N/A |
On some revisions, there is a 4-pin SPEAKER header right next to the front panel. Do not confuse it with pins 1-4.
Summary: this document describes the front-panel connector, signals, pinout, LEDs, switches, common troubleshooting steps, and wiring recommendations for motherboards labeled iPSiB‑VR Rev 1.01 (Acer laptops/mini-PCs that use this board). Use this as a practical reference for repair, modding, or replacement front-panel assemblies. Assume your board is labeled Rev 1.01; variations may exist between batches — verify against the board silkscreen and multimeter before powering.
Warning: working on motherboards can damage components or cause injury. Disconnect power, remove battery (if applicable), and ground yourself to avoid static discharge.
