Dead keyboard backlight after top case replacement
I recently replaced the top case on my Early 2011 15" Macbook Pro running OSX 10.8.5. This is the first time I've ever undertaken anything so ambitious, and everything went well with one exception: now my keyboard backlight is completely dead.
For the record, I've gone into System Preferences to uncheck "Adjust keyboard brightness in low light." And of course, I've hit F6 many times to make sure brightness is turned up. F5 and F6 seem to work fine according to the display indicator - it's just the backlight itself that doesn't work at all.
When installing the logic board in the new upper case, at first I did forget to reattach the ribbon cable for the back light (it was briefly stuck underneath), so I had to backtrack a few steps to reattach the cable.
After the problems, today I reopened my Macbook Pro and repeated the steps related to the backlight cable. After completing the other necessary steps, I flipped up the retaining clip on the cable, pulled the cable out, reinserted it, then secured the retaining clip. But after reassembling and closing the case, the backlight is still dead.
Is there a chance I damaged the cable when it was briefly stuck underneath? Thanks in advance for any ideas or suggestions.
Is this a good question?
