To be a little clearer, I used my multimeter to check continuity through the switches. I don't know why these seven keys are dead or unreliable, but I imagine if there's any hope of repairing them, I'll have to somehow separate the keyboard PCB from the keys and top plate. Or maybe it just needs some compressed air to blow out some dust? Are the contacts sealed? Any hints on how to undo the dozens of plastic rivets apparently holding the keyboard assembly together? |
