hello,

problem appeared have begun randomly. used computer in morning no problems. when used computer again in afternoon, keys no longer worked do. nothing abnormal happened between 2 times.


verified , repaired disk , permissions using disk utility after noticed problem. nothing changed after repair , restart. updated operating system newest update in app store , restarted, nothing changed.

weird problem. maybe liquid damage of keyboard wiring/circuitry?

can try hard power off holding power button down until machine turns off , turn on again?
