Unlike retail motherboards (ASUS, Gigabyte), Acer does not always host detailed user manuals for OEM motherboards. Instead, the documentation is embedded in the system service guide for the specific PC model.
Since a direct manual doesn’t exist, use these alternatives:
Visual Match: Search for "Acer IPIMBAR Rev 102A high-res image" on forums like Badcaps.net or Tenforums. Users often annotate the "top" (component side) with exact pinouts.
Intel H110/H170 Standard: The Rev 102A often follows the Intel Front Panel I/O Connectivity Design Guide. If pins 1-2 are PLED, 3-4 are PWR, 5-6 are HDD, and 7-8 are RST, you’re safe.
The "Acer IPIMBAR Rev 102A manual top" doesn’t exist as an official PDF. But the front panel header layout above works for 99% of users. Bookmark this page—you’ll thank yourself when the PC won’t power on.
Need more help? Post a clear photo of your board’s bottom-right corner on Reddit’s r/buildapc or r/techsupport, and tag the model number.

Look for small 2-pin connectors labeled from your computer case:
In the world of computer maintenance and repair, the motherboard is the nerve center of the system. For technicians and enthusiasts working with older Acer desktops (such as the Aspire XC series), the Acer IPIMB-AR Rev 1.02A is a familiar sight. However, working on this motherboard without a reference guide is like trying to assemble a puzzle in the dark. The manual for this specific board is an indispensable tool, providing the roadmap necessary to unlock the hardware’s potential, troubleshoot issues, and perform upgrades.
On the Acer IPIMBAR Rev 102A, the front panel header is typically a 9-pin (or 10-pin with one missing) block located on the bottom-right corner of the board.
Here is the standard "top" layout for that header (viewed from above, with the board mounted in a case):
| Pin | Signal | Pin | Signal | | :--- | :--- | :--- | :--- | | 1 | Power LED (+) | 2 | Power LED (-) | | 3 | Power Switch (+) | 4 | Power Switch (-) | | 5 | HDD LED (+) | 6 | HDD LED (-) | | 7 | Reset Switch (+) | 8 | Reset Switch (-) | | 9 | Empty / Key (No pin) | 10 | +5V or NC |
Pro tip: Pins 1-8 are active. Pin 9 is often missing to prevent incorrect orientation. The power button only needs pins 3 & 4 (polarity doesn’t matter for the switch).
