Trackpad and Keyboard fail randomly, MacBook not usable
The Trackpad and Keyboard of my MacBook Pro 13" Mid 2014 (A1502) just stopped working properly. Everything was fine but when I started it yesterday, the Trackpad would just respond every 20 - 30 seconds or so and then just for a few seconds. The Keyboard responds about 50% of the time but some (random) Keys won't work. Additionally, sometimes the letters appear a little later compared to when I pressed the key.
The mouse pointer works with an external USB connected mouse but this one hangs sometimes as well, but just for half a second every now and then.
I tried resetting NVRAM and PRAM and also erased the hard drive and installed Sierra completely new, but without any success. I can't imagine, it's a faulty Trackpad AND Keyboard.
I didn't spill any water over it and I didn't move it at all before the issue occurred first.
The codes given by Apple Diagnostics are:
I'm grateful for any help. Cheers!
Putting it in the fridge for 2 hours didn't help at all :-(
I connected a Magic Trackpad via Bluetooth that worked perfectly a few days ago but now has the same issues like the external mouse and lags every 10s for half a sec.
That's why I think the issue is probably not hardware-related but has something todo with the drivers of the periphery. What do you think?
I already installed the OS completely new without success, is there a more thorough way of putting the macbook back to factory-setup?
Bu iyi bir soru mu?
