Hi I've a problems with this kind motherboard. Only the first green led is on, but if i press the power switch nothing happen. No short on the board, and correct tension on the power switch (3.3 V) I tried another machine and tested it with another source, CPU, graphics and memories ... and it's still the same! On board: - I have 3v on the bios and the power button and zero when pressing. -I have 12V and 5V coming U7700 ISL62383 Any suggestion? Thanks |

Hi. Do You have a schematics and boardview? Do You understand, what means 2nd,3rd,4th, ..., 11th debug LEDs? Yes, You have 11 debug leds on this MOBO, but only 4 are soldered on it. What do You want? It's not a primary school for hardware repair stuff. 5V and 12V - it's all, what are You measured on MLB? |
