[iClub]

Hi, this mac had been repaired and come back, the first time had oxidation in the pads u8160, u8005, and u5110, I cleaned with the mesh.
Now the mac just lights the orange led of MagSafe.

More things affected by corrosion.
Did you reball SMC?

Check SPI Bus Series Termination resistors and their traces.
Clean/remove J6100.
Try to start in SMC bypass mode.

It solved. I was in the region of u6100 and the mac called again, thanks.
