Liquid damaged my keyboard and a few keys stop working. I wanted to replace a new keyboard and add a new backlit to the MacBook Unibody Model A1278 late 2008.
Thanks to ifixit and the tools they provide,it makes the job very easy and smoothly!!
Took me 3 hours to get everything working again! But was worth it!
Be patient and follow the guides carefully! Listen to some music while you take your time! Have fun and be safe!
