Note: The "Power LED" pins are often a 3-pin header (pins 2, 4, 6) on some Acer boards, so refer to the white outline printed on the motherboard surface.

The Acer Q65H2-AM is a proprietary micro-ATX motherboard designed for Acer Aspire desktop systems. It is based on the Intel H61 Express Chipset (or similar Q65 variant depending on the specific CPU generation supported) and is designed to support Intel 2nd and 3rd Generation Core processors (Socket LGA 1155). | Feature | Specification | | :--- |

  • Intel Q65 Express Chipset Reference – This motherboard uses the Intel Q65 chipset. General Intel Q65 documentation will cover supported CPUs (Sandy Bridge/Ivy Bridge with BIOS update), RAM (DDR3), and SATA ports.

    • Unlike retail motherboards, Acer OEM boards often use proprietary jumpers. Based on v1.1 board markings: Intel Q65 Express Chipset Reference – This motherboard

    | Jumper Label | Function | Default Setting | | :--- | :--- | :--- | | CMOS1 | Clear CMOS | Pins 1-2 (Normal). Pins 2-3 to Clear. | | ME_JUMP1 | Management Engine (ME) Disable | Leave Open (Default). Closed for service mode. | | PSWD1 | Clear Password | Short to reset BIOS password. |

    Critical Note: The Front Panel Header (Power SW, HDD LED, Reset) on v1.1 is often a proprietary 9-pin block. Do not use standard ATX pinouts without verifying voltage with a multimeter, as pin 7 may be +5V instead of Ground.
