Problems with MacBook Pro Late 2011 replacement keyboard flex cable
A while back, my computer overheated and fried my keyboard so that only a few keys would work and, when typing, often a bunch of random characters would input.
Recently I’ve cleaned out the whole computer, put new thermal paste in and have been trying to replace keyboards. The computer runs a good 15C cooler, but the keyboard just won’t work and I’m 90% sure it’s the connector ribbon. The thing that I don’t get is that the backlight connector works without any problem and without the clamp as well.
On my first keyboard replacement (keyboard from China via Amazon)…the keyboard mostly worked, but then stopped (I think I scratched part of the connector ribbon when trying to install it.
On the second keyboard (from iFixit) it started working great for letter-only keys…all keys around the periphery (enter, spacebar, tab, etc) all didn’t work. After trying to re-insert the ribbon, it just plain doesn’t work at all now. (Note, I’m not using the ribbon clamp because it detached and it’s so small that I need to figure out a good way to get it back on). I’ve tried to use electrical tape as a shim, but it doesn’t seem to do anything
All that said, I do have some more specific questions:
- Clear blue plastic - The keyboard connector ribbon has what seems to be a blue plastic covering (maybe tape) on the tip…do I remove this?
- How far in is the ribbon supposed to go? When fully installed are you supposed to see connector ribbons in the cable? The cable is so small/fine that I feel like if I force it in it’s just going to break/scratch.
- Does it make sense if only some of my new keys work due to a bad cable connection? If so, what’s the best way to ensure a good connection and reinstall the cable clamp.
