Trackpad is not working, keyboard freeze in every 3-4 second
I’ve just bought a mid-2014 MacBook pro with non-working touchpad. Only the clicks are working at the bottom of the trackpad but it’s ok because I prefer mouse.
But the main problem is the built-in keyboard. When I start typing, it freezes or disconnect for a sec in every 3-4 sec. In the keyboard settings some options disappear in the same time when it freezes. It doesn’t matter which key I press, it doesn’t work. It takes a lot of time to type because of this. I’m trying to find the reason of this but I can’t. Everything works fine with an external keyboard.
Have you seen any problem like this?
