Most common cause of "PC won't turn on" errors. The header is typically a 9-pin block (2 rows). Acer often uses a proprietary layout, but the H11H4-AD follows Intel standard:

| Pin (Odd) | Signal | Pin (Even) | Signal | |-----------|-------------|------------|-------------| | 1 | HDD LED + | 2 | Power LED + | | 3 | HDD LED - | 4 | Power LED - | | 5 | Ground | 6 | Power Switch| | 7 | Ground | 8 | Reset Switch| | 9 | NC (empty) | 10 | Key (no pin)| If you still need the original Acer content:

Note: Power LED is often a 2-pin separate block. If your case has a 3-pin Power LED, plug it into pins 2 and 4, leaving the middle pin empty.

Missing from most online PDFs: The exact fan header amperage, clear CMOS jumper location, and power-on pinout. Most common cause of "PC won't turn on" errors

Acer never released a standalone manual titled "H11H4-AD User Guide". Instead, the motherboard documentation is embedded inside the user manual of the complete PC model (e.g., Aspire TC-780, Veriton M4640G).
