Sometimes it would also freeze whilst using the device too. I've had 5 different software engineers, 4 leads, look at this issue and the only thing anyone could think of doing was wiping the hard drive and starting from scratch. Both the keyboard and trackpad stopped working and I had to force a reboot by keeping the power button pressed. Moreover, Apple also releases few fixes through the software update that ultimately turns into preventing hardware functioning appropriately. Exact same machine as yours. I've read dozens of articles, and most recommend replacing the ribbon cable above the battery, as that seems to be what is causing the problem. If your business provides MacBooks to its employees, you may occasionally receive a complaint from a user whose trackpad has been turned off.
Please don't link directly to downloads. Apparently the cable that connects the track-pad and keyboard needed replaced. My model has this problem because of water damage that seems to have affected the relationship between power button and battery. I used to use the ones on the internal, as they were one of the few buttons that still worked. I need to disable the internal keyboard and just use my external so that I can wipe the macbook and hopefully sell for parts, but I can't get past the login screen.
The internal keyboard and trackpad doesn't work anymore. In these cases, the backlit keyboard is disabled. So I can't get into the system. I got the same error messages as the posters above, but it still seems to disable the keyboard just fine. Or a prolonged period of no usage. So you have to check at every regular interval of time either the system is well updated or no.
The backlit keyboard is attached to the top of the metal causing inside at the Mac. I get 7 files, move it outside that folder and it works. There's no way this is hardware, the power-option-command-shift buttons all work to quickly turn off the system. The problem: I can't get my keyboard to light up. Unfortunately, this means you have to be not using your computer at that point.
Before I can try any suggested fixes, I need to figure out how to re-enable it. It started working on its own one day and stopped again. Any clues on how to fix this? Use a small piece of tape to create a pull tab to help in removing the cable and use care when opening the clasp as it can break! I ever-so-gracefully knocked a cup of coffee on my macbook last week. It occurs when the keyboard is replaced with another keyboard of a different model. Any ideas how to make this shortcut lock out the keyboard? Yes, all the way down, not sleep or logging out.
The built-in trackpad will automatically start working again once the mouse or external trackpad is disconnected. Click ignore trackpad when mouse keys is on Doing the above turned off most of the letter keys but still allowed the music control keys at the top of my keyboard to still work. My keyboard, however, is screwing up. I have tried to update my software which told me I was up to date. Well, I will explain you. With the external keyboard, I did the hardware test - everything ok - and nvram reset - no change. I couldn't find any information online about my problem and decide to plug a windows keyboard in my MacBook Air.
I'm most concerned about my data and I plane to get a hard drive first thing tomorrow. This code is going to be used for systems that I build for my company. Let us go and solve it very soon. I honestly don't really know why the error appears. Sorry, the problem came back again after deleting login files.
I need to disable the internal keyboard and just use my external so that I can wipe the macbook and hopefully sell for parts, but I can't get past the login screen. Depending on how you have your MacBook positioned, however, this may be troublesome, as a misplaced hand or the paw of your friendly household pet may trigger unwanted cursor movement. While flicking through my desktops, I noticed the Force Touch trackpad would not return the 'clicking' sensation back when I pressed. Some people told me about troubles with Sierra. So I was thinking to: - remove the keyboard cable from the logic board and use always an external usb keyboard.
