The H61H2-AD adheres to a custom micro-ATX form factor (approximately 244mm x 200mm), though it often utilizes a non-standard mounting hole configuration common to Acer OEM (Original Equipment Manufacturer) builds.
The is a LGA 1155 desktop motherboard. ECS (Elitegroup Computer Systems) manufactured this board for Acer OEM desktops like the Aspire M1935, M3970, and X3990. Because it is an OEM piece of hardware, finding an official manual or a layout diagram can be incredibly difficult.

If you own this board today:
Since no manual is available, here are the confirmed jumper functions. The jumper block is located near the SATA ports and the CMOS battery.
: In some rare cases, a "Setup Guide" or "User Manual" is available for download. However, these are generally not the in-depth motherboard service manuals with full schematics but rather basic setup posters. For the H61H2-AD, a comprehensive service manual with circuit diagrams is considered proprietary and is not publicly released for legal repair purposes.
The Acer H61H2-AD is a proprietary motherboard architecture developed primarily for Acer’s mid-range desktop series, most notably the Aspire M3 and M3910 models. Based on the Intel H61 Express Chipset, this mainboard represents a transition point in PC hardware history, bridging the gap between the aging LGA 775 architecture and the second-generation "Sandy Bridge" LGA 1155 platform. This documentation serves as a deep technical exploration of the board’s layout, connectivity, and operational constraints as derived from the service manual specifications.
