Keyboard and trackpad not working after replacement of parts
I recently found an old MacBook from my GF that had to her knowledge ‘stopped working’. It went through some minor damage during a car accident but after worked fine for a year or so before stopping completely.
When I picked it up and connected it to the adapter it started up, booted and worked for a few hours. After disconnecting the power supply it closed down and it would not start back up again.
Because I noticed that the battery was very bad I ordered a new one. Also the trackpad glass was broken (but still worked) so ordered that as well.
With the repair I accedentily broke the speaker connector on the I/O board. After that it would not power up anymore. So I ordered a new one and replaced the IO board. After that the MacBook booted and got into the loginscreen.
But now, the trackpad and the keyboard are no longer working. An external mouse works just fine.
Any ideas on how to proceed?
