    820-00850 fan at max rpm and only one is spinning

    Titles says it. When I turn the board on one fan kicks up to max speed immediately. The other does absolutely nothing. Was fixing an audio issue around U6400 but cannot say whether or not that's when it started. I can confirm once upon a time the board worked fine though. Not sure if it was...

    820-01700 ppbus_g3h short to ground nothing heats up

    Injected 1v 1a into ppbus_g3h and nothing got the slightest bit warm. Thought I was crazy but freeze spray revealed nothing also.

    820-01700 no power, cycles between 5v and 19v

    Haven't had the chance to inspect yet. About to pull it out now. Only the second A2141 board I've worked on so not familiar with common problems. Figured I'd ask if this is indicative of anything specific. But it just jumps from 5v to 19v for a few seconds then the meter goes blank like it was...

    Ok so this board has been thru hell :/ Had water damage. Fixed water damage and it worked perfectly. Was putting back in top case and there was a bee in my room and I kinda maybe might have thrown the board at the bee :p and surprisingly everything still worked perfectly except the backlight. I...

    820-00850 no audio

    This one was shelved a few months ago so not exactly sure what I've tried. It's one of my boards, not a customer so it hasn't been a priority. But basically it just has no audio. Well actually the internal speakers do work for a few seconds after boot, usually like 10 seconds into a YouTube...
