shorted the magsafe module against ground

I have a Macbook Pro mid 2010, and when trying to fix a keyboard I mistakenly shorted the magsafe module again ground, which of course shorted the board.

I'm pretty sure this is only a fuse issue between the magsafe module and the SMC, Would you be so kind to provide the schema of all the possible fuses on the board, I have tested a few which where obvious but some aren't that obvious.

My board is: 820-2850 A

thank you very much

kangoooo2000 which fuses did you test? Going to convert this question that you left as a comment to a separate question. That will allow you to add images of your board to the question. Use this guide for that.

Thanks for your fast answer,

Those 2 were good, so I tested the charger on an other macbook and the light did not come on, I unplugged it and plugged it back in the wall socket and it came back to life, thank you charger for your safety feature :D

I have an other question, the Macbook pro in question has same water on the keyboard, I took it appart and there is no water damage (good thing), although the keyboard does not work even after cleaning the connector on the board and on the keyboard, the keyboard seems fine and does not have any corrosion.

I also tried with an external keyboard with no luck, which is very surprising because normally it should work, you should be able to make a verbose boot or do an NVRAM reset with a external keyboard. oh and the power button does not work either (maybe because it is also connected to the keyboard).

Do you thing I should look for a state change with a multimeter when pressing a key to rule out the keyboard?

Thanks Philippe
