Answer to: MB will not charger after a soda spillhi there, I'd the same probs with a MacBook UB Alu 2,0GHz from a friend. The MB was dead after a soda spill and I tested all the components. I've found out, that there is a very tiny board with the battery-state-LEDs on it... But on this board is much more: There is also the battery load control on it. The soda spill flooded this board and the battery's energy did the rest... Most of the passive components on this board were destroyed and the "best": the whole machine seemed to be dead... But only this tiny board was defective! I deactivated this board and the MB runs with Power Adapter connected (but not with battery-power!!!). The board is connected by the little connector near the battery-connector on the mainboards other side. The tiny battery-load-control board is located on the left side of the MB where the battery-state-LEDs are. To get it out, you have to take out the metal-shield from the battery-connector. Now you can see the cable to this tiny board, behind a metal. There 4 screws holding the board...
Answer to: LED Backlight not working after liquid spill?There is a microfuse near the battery-connector. It has a value of 6A. It comes in a very small SMD-format. On it you find the designation: "F09 - 6A". But it is the main-fuse of the book, not only for the LED-backlight! I have the same problem like you: After a liquid spill I have repaired some components (also the microfuse). The main problem was the battery-load-indicator near the battery: The water did a very effective job there: The tiny board with the little battery-test-switch and the load-indicator-LEDs was completely destroyed and caused a short circuit on the motherboard, making the main microfuse blew... Now I'm looking –like you– for more information about the LED-backlight: - Where is the power supply for LED backlight? - Which connector (or connection-pin of the disply-data-cable), is powereing the backlight? I hope someone can help us??? Best Regards Georg
