Apple wired keyboard with Numpad stopped working after power outage?

[telepati]

Hi, just like the title says, after the power outage my wired keyboard stopped working. Here's what I've tried so far;

• SMC/NVRAM reset
• All other USB ports
• USB extension cable to all ports
• Checked USB ports with another keyboard. It is worked, that's mean there are no problems with the ports.
• Checked the broken Keyboard with PC, it didn't recognize (tried all ports on the PC, USB 2.0, USB 3.0)
• Both USB ports (L/R) under the Keyboard also working

Do you think it means the keyboard is short-circuited and can no longer be used?

What do you suggest more?

Same thing happened to my mac keyboard after losing power for a few seconds today. I actually flipped the breaker while tracking down a circuit, so it wasn't a surge. I've tried the keyboard on other computers with no luck. Also confirmed all USB ports on the 2017 iMac that it was connected to are functioning properly.

I read somewhere else to unplug the keyboard and wait a few minutes, then plug back in. Still no luck.

I will follow-up if I find a solution

This is what worked for me. Basically an SMC reset, which makes absolutely no sense to me since I've isolated the issue to the keyboard.

• Power off the iMac
• disconnect all peripherals and power
• Hold down power button for 30 seconds
• Reconnect power and turn on. Leave everything else disconnected
• Reconnect Keyboard
• Repeat

Worked for me after the second attempt. Maybe it just needed a little longer for caps to drain in the keyboard, or maybe the iMac is sending a command to the keyboard. No

I'm pleased to hear that solution works for you, but I already tried that too many times. I just forgot to add this to my main post. Furthermore, I almost tried everything on the net, there is only one silly thing left that I didn't try, cos, this is the most stupid thing that I heard of. Washing Keyboard in the Dishwasher. I'm very close to try that 😁
