Hi, is it possible for a top case failure to be linked to the replacement of a faulty logic board? The problems with the top case began immediately after I took my MacBook Pro in to have the logic board replaced. Many thanks for your help in advance!

What problems are you having with your top case?
Hi T5BRICK, I'm often blocked from logging in (around 9 times out of 10) with the correct password. The reason seems to be incorrect key input. For example, when I press 'delete' or 'return' that creates an input. Also, when I first got the laptop back, the cursor was racing down the page.

I'd guess that somehow the keyboard cable from the top case to the logic board was damaged, not plugged in quite right, or the replacement logic board has issues as well. If the cursor was racing down the page and you're having trouble typing due to incorrect key input, I'd be taking it back to the service center to have it repaired again.

Thanks for the info. Yes, I took it back to the Apple-authorized service centre where I got the new logic board installed, and told them the problem occurred straight after their servicing, but they're still trying to charge me a lot for the repair. I just wanted to check that I was justified in arguing with them on that count. Many thanks
