Title:

Repair complete but no power

Text:

Okay, so I followed the very clear instructions on how to replace the logic board - not that I was going to replace it, but I suspected it need cleaning up.  I'd seen a number of reports of similar graphics freezing problems which appeared to be related to dirty logic boards.

Now it's all back together but...  when I plug it in, there is neither a green nor an orange light on the charging cable.  Also, when the battery was inserted as the last step, it started a short - maybe 30 second - clicking like when you flip a piece of cardboard past the spokes of you bike wheel.  It then stopped for maybe two minutes and started again for say another 30 secs and so on until the battery was dead.  I have a battery with a life of about 5 minutes so this cycle went on overnight and then, presumably the battery was dead.  Naturally, I have to add that pressing the power button did absolutely nothing.

I know it's vague, and I'm sorry, but can anyone suggest what I might have missed or done wrong?  I'd love to be able to save my MBP.  The Mini I bought when the graphics problem made the MBP too unreliable just doesn't cut it.
