Chosen Solution
Hello guys! I’ve got an Apple Wireless Keyboard A1255. Year 2011, but its in very good shape - rarely used, never spilt any coffee on it. But a week ago it ceased to turn on. Replaced the batteries, sometimes they’re too short so I do know that tinfoil ball trick to close the circuit :) However, its still not turning on. I’ve checked with teardown//dissassembly tutorials here and have almost completed it. Most circuits are fine - checked the ohmage with multimeter - but cant check the voltage (because the meter is malfunctioning). Has any of you had any success with repairing it (unless the logicboard is dead)? Yes, I can throw it away at any time, but would like to give it some last chance. :)
As far I am concerned, these keyboards are unrepairable when they fail. Well at least you can still change the batteries in those models, the newer ones have a soldered lithium battery. Check this guide, it might provide some help: Apple Wireless Keyboard (A1255) Teardown
