Keyboard replacement -- securing keyboard to topcase
MacBook White Unibody Core 2 Duo A1342 Late 2009
This old Mac still works perfectly other than a keyboard that became completely unresponsive after an injudicious attempt to clean it with a barely wet sponge 3 or 4 years ago.
Since then we've overcome this deficit with a wired keyboard.
However, as the Mac still functions very well, I want to give it a new lease of life and replace the built-in keyboard.
Yes, I know this is not an easy job as the keyboard is glued and plastic-welded into position and a backing plate that covers the underside of the keyboard is also glued -in place.
There are no iFixit videos or guides for this job but I did come across two YouTube videos that show how it may be done.
Video1 uses an exacto knife or scalpel to remove the backing plate and then places the new keyboard over what's left of the 105 (or so) small plastic studs which acted as plastic rivets on the old keyboard.
Surprisingly, no attempt is made to glue or plastic-weld the new keyboard. The backing plate is, however, glued in place with superglue plus activator.
Even more surprising is that in Video2 each of the 105 (or so) small plastic studs that protrude through the keyboard are carefully removed with an exacto knife.
No further attempts are made to secure the new keyboard in place other than the rigidity of the glued-in backing plate placed over it.
Given that Apple seems to have used a combination of glue and 105 plastic rivets to ensure that the keyboard is held tightly in place, I find it hard to believe that a replacement keyboard requires nothing more than the overlaying backing plate to impart solidity to the keys of the keyboard.
If anybody else has actually done this job on an A1342 Macbook, what has been your experience with securing the new keyboard in place.
Is dit een goede vraag?
