[xxturexx]

hi to everyone! this is my first post!
Im sorry for my bad english!
yesterday i bought an used faultY macbook pro 13 early 2011 ( a1278 ) with i5 cpu, about 300 euro
im very happy its work very well!
the components fault are:

- button with level indicator battery
- microphone
- keyboard backlight

So, the keyboard backlight not work becouse the connector on motherboard is missing/broke.
what can i do? how can i fix it?
its possible make homemade backlight? there are any schematics about it?
