Help me to identify this transistor of my motherboard

The only way I see it to identify that board is to find someone who has this exact board and ask them to take a photo of that SMD-transistor. Usually in repair shops they do it like this: measure what’s what and where, take old one off MoBo, solder a similar one found by speculated specs and voila. Most of the time that works.

I searched google, there’s NEITHER BIG ENOUGH PICS NOR SCHEMATICS TO SEE SOMETHING THAT SMALL…

@keteflips old question and I am sure that by now you have this fixed :-) Anyhow, that transistor looks like a MMBT3906L Mot N 2N3906 in a SOT23 package
