Keys not working - need to replace entire keyboard?
The left and down arrows on my keyboard aren't working, but all other keys are fine. I removed the key caps and cleaned the interior parts, but that didn't help. Pressing on the rubber key cup nipple doesn't do anything. As far as I understand, that means that the issue is in the keyboard's circuitry or other finicky parts, and not the key itself.
What other parts could cause this issue? Would buying replacement keys help? Is there any way to fix it without a complete teardown of the upper case?
Thanks!
