4. Front Panel Header (JFP1) – The Missing Diagram

This is the most requested information for the REV 102A. The 9-pin header is located at the bottom-right corner (near the SATA ports).

Pinout (Left to Right, Top row then Bottom row):

| Pin | Signal | Color (Typical Acer case) | Pin | Signal | Color | | :--- | :--- | :--- | :--- | :--- | :--- | | 1 | Power LED + | Green/White | 2 | Power LED - | White | | 3 | HDD LED + | Red/White | 4 | HDD LED - | White | | 5 | Ground (Power SW) | Black | 6 | Power SW | Yellow/Black | | 7 | Ground (Reset SW) | Black | 8 | Reset SW | Blue/White | | 9 | NC / Spare | N/A | | | |

Troubleshooting JFP1:

No power? Short Pins 6 & 7 (Power SW to Ground) with a screwdriver.
LEDs reversed? Polarity doesn't matter for LEDs – they'll just not light. Flip the connector.
