Long story short - I took my MBP to my local Apple store to have the trackpad fixed since it was coming up from the casing. Anyway, I haven't extensively used my MBP until tonight when I noticed that my keyboard lights no longer work. Yes, I shut off all the lights in my room, and even installed Lab Tick, but to no avail. I'm going to be really disappointed if Apple caused this and I have to be without my laptop again for almost a week. Is there anything else to suggest that I can do before I have to bring my MBP once again back to Apple? Thanks in advance.
