I have a Acer AN517-51 which i had the board replaced, but now, the fan for the video card do not work, after the rapair, and i cannot seem to be able to access the fan control either, from the errors it seems the bios does not recognise it.
Can any one give me a hand on how to trouble shoot this, and if not, how to overwrite the bios setting, of the model and serial so i can see if that fix the access to the fan controls?
