Acer G41tam Rev 10 Manual Extra Quality -

Some revisions have a BIOS_WP jumper (near the BIOS chip). Setting it to Enabled (pins 1-2) prevents accidental BIOS flashing—useful for legacy systems running older OSes.

This is the #1 reason people search for a better manual. Most generic manuals show a standard Intel pinout. They are wrong.

The Acer G41T-AM Rev 1.0 uses a 12-pin front panel header (labeled FP1) arranged as: acer g41tam rev 10 manual extra quality

Top row (pins 1-6):  Power SW, HDD LED, Reserved
Bottom row (pins 7-12): Power LED, Reset SW, Ground

Here is the extra quality, verified pinout:

| Pin | Signal | Function | Wire color (typical) | | :--- | :--- | :--- | :--- | | 1 | PWR_BTN# | Power button | Orange/White | | 2 | HDD_LED (+) | HDD activity (anode) | Red | | 3 | HDD_LED (-) | HDD activity (cathode) | White | | 4 | GND | Ground | Black | | 5 | NC | Not connected | - | | 6 | GND | Ground | Black | | 7 | PWR_LED (+) | Power LED (anode) | Green | | 8 | PWR_LED (-) | Power LED (cathode) | White | | 9 | RESET_BTN# | Reset button | Blue/White | | 10 | GND | Ground | Black | | 11 | GND | Ground | Black | | 12 | +5VSB (fan) | Standby power for fan | Red | Some revisions have a BIOS_WP jumper (near the BIOS chip)

Pro tip: Pins 11 and 12 can sometimes power a low-amp chassis fan for always-on cooling—a hidden feature missing in low-quality manuals.

Acer never published a standalone manual for the G41T-AM. Instead, the motherboard documentation is embedded within the Aspire X3810 Service Guide (Part No. 41.A9807.001). You can locate PDF copies on: This is the #1 reason people search for a better manual

The service guide includes board layout, exploded views, and BIOS POST codes.

The manual must specify that Rev 1.0 uses a standard 24-pin ATX main power connector and a 4-pin +12V CPU connector (not 8-pin). Using an 8-pin EPS cable may require splitting; consult the pinout diagram below.
