No Keyboard Backlight And No Bottom Ram Slot Macbook Pro 13 Unibody Mid 2012
Chosen Solution Working on a MBP 820-3115-B without keyboard backlight. The board has another issue, it will produce a 3 beep RAM error if the bottom RAM slot is populated. It boots and works fine with a single RAM module installed in the top slot. Even though a faulty bottom RAM slot is a fairly common issue on this model (the legs of the RAM slot detach from the board, but I checked them on my board and they’re solid), I believe the 2 issues might be related....
