[SOLVED]820-00165 Fan spin, no chime - vcore present

Hi there,

I've just had a board in thats had a lot of work done to it :-(

So symptoms are:

Fan spins for about 5 seconds when connected to power then stops. Then it starts again and stays on - fan goes high.

I have gone through all the power rails - all present including vcore at 1.8v.

Does anyone have a clue what it could be?

I obviously have zero hints due to loads of old flux etc.

Thanks
Jamie
 
UPDATE: Might have been a bit quick to post - looks like someone replaced the SMC but it looked awful - reflow seems to have it powered on and working. A lovely bath needed I think!
