There doesn't seem to be much information about all of the codes as far as I can see, there was a site referring to B2 code and the B10 code. The B10 code refers to an errant standoff that could short the Lan port if it is not removed.

You might just make it easier on yourself to add all your hardware specs, brands, speed, watts, volume, model serial numbers etc and then add the problems you are facing.
Otherwise, perhaps your booklet has a website listed. you might have to just type in each error code number then "error code" example
B2 Error code
and do an individiual search for each of them, rather bothersome if there are hundreds of them.
The only thing I've actually found, just now, refer more for Windows Installer than the Mpower specific error codes.

You could give us the error code and explanations as per the booklet and then we might be able to explain the technicalities pertaining to it, maybe.
