Chosen Solution
Hello guys! I’ve got a Wireless Keyboard A1255. Year 2011, but its in very good shape - rarely used, never spilled 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. :)
This teardown I did may be of some use to you as I really tore it down. And it is the A1255 Apple Wireless Keyboard (A1255) Teardown
