In MacBook Pro the power button permanently attached to the keyboard via a ribbon cable. It’s easy to install. Just unscrew the back casing (you do need a special screwdriver that can also be bought on Amazon for a few bucks). The cable itself just plugs in after unscrewing a couple small screws holding it in place. The 3rd-party vendor cable that Apple installed in many Macbook Pros were crap. The Macintosh Plus keyboard, like the original Macintosh Keyboard before it, used a coiled modular cable similar to a telephone handset cord. Introduced and included with the Macintosh Plus in 1986, it was an extended keyboard that had a built-in numeric keypad.

After each step please test to see if your keyboard is working:
1. Restart your Mac. It is simple but effective. Restarting your Mac may fix your issue. To restart your Mac, click the Apple menu > Restart.
2. Check your keyboard batteries if applicable. Some USB keyboards have batteries. Open the battery part of the keyboard and check to see if the batteries are placed correctly. Also, try replacing the batteries.
3. Check the USB connections. It is possible that your Keyboard is not properly connected to your computer. Try the following tips:
- Switch the keyboard’s cable to another USB port on the same Mac, if possible.
- Unplug your keyboard and replug it into your Mac firmly and securely.
- Ensure that there is not anything (debris, dirt, etc) obstructing the connection in the USB port. If there is, try to remove it.
- Disconnect all connected devices from your Mac. These can be a mouse, keyboard, printer, etc. Now reconnect your keyboard and mouse back into your computer. If you can use your Keyboard now the problem may be with one of the other devices. What you can do is to try replugging them one by one until you find the device that is causing the problem.
4. Reset the SMC of your Mac. Your USB port may be having a power-related problem and resetting the system management controller (SMC) can fix your problem with your keyboard.
- It is highly likely that this is a desktop computer. If it is, resetting the SMC is very simple. Follow the steps below:
- Shut down your Mac by choosing Shut Down from the Apple menu.
- Unplug it from the power outlet.
- Wait about 15 seconds.
- Now replug it into the power outlet.
- Wait another 5 seconds.
- Now start up your Mac by pressing the power button.
- If this is a Mac Notebook, the steps are a little different. We previously wrote about this topic. Please see that article on how you can reset the SMC.
5. Reset NVRAM or PRAM on your Mac. This is really easy. Here is how:
- Turn off your Mac.
- Turn on your Mac and quickly press Option, Command, P, and R keys together.
- Keep holding the keys for about 20 seconds.
- Then release the keys. Your Mac will restart.
6. Update your Mac. Update the software on your Mac. Here is how:
- If your current macOS version is Mojave or later (e.g., Catalina): On your Mac, go to Apple menu > System Preferences > Software Update. This will check for updates. If there is an update available, click the Update Now button.
- Other macOS versions: Launch the App Store on your Mac and click Updates.
7. Boot into Safe Mode. Restart your Mac in Safe Mode. Here is how:
- Turn off your Mac.
- Turn on your Mac and quickly press and hold the Shift key.
- Keep holding the Shift key until you see the login screen. Safe Mode can take up to 10 minutes so be patient.
- When your computer is in Safe Mode, test your keyboard, is it working now?
- In any case, restart your Mac normally. Do not press the Shift key.
- When your computer restarts, test your keyboard again. Did Safe Mode fix it?
8. Delete preference files. Your preference file may be corrupt and deleting it may resolve your issue. Here is how:

About 2 weeks ago I bought a second hand Macbook. This is a 13-inch, Aluminum, late 2008 model.
So I contacted the owner, bla bla bla, and I knew the internal keyboard was not working. But I got a exernal USB Apple keyboard with it, so no big deal for me.
I build my own pc and upgraded my laptop before and know a lot about pcs. Once the Macbook was home, no problem at all except the internal keyboard ofcourse. I bought a new internal keyboard for my laptop and installed it. Still it doesn't work.
Long story short: internal keyboard not working, replaced it with a new one and same problem.
- Trackpad works perfect
- Powerbutton works perfect aswell
- Running OS X El Capitan 10.11.6
- Harddrive was once replaced
As I heard from the previous owner before: they were browsing the web and suddenly the keyboard stopped working. They just bought an external one then. They did say sometimes it would work for a moment.
2 weeks in my hands and never worked once.
This is what I tried so far:
- Checking for mouse buttons (this is off)
- Resetting PRAM or so (alt + cmd + p + r during boot)
I could use all help to fix this! If you think something might help, please respond! I have no money left to buy other things (I'm 18) so don't say 'Just buy a new mac'
MacBook, OS X El Capitan (10.11.6), 4GB ram and HDD replaced once
