One of our wired Apple keyboard has a collection of keys which are no longer functional. Some are on the top row as well as Delete, Return and a handful of others. This model is a A1242. We are very fond of this compact wired model.
What causes this anomaly? I am thinking best to replace rather than repair. I have also heard there are some tinkerers and folks who favor reducing waste on this list. Looks challenging to open. What possible solutions exist to repairing it?
