i have a MacBook Air 13" Late 2010 without the backlit. I was wondering is it possible for me to change the keyboard with backlit that used by MacBook Air 13" Mid 2011 onward. Because i find it very difficult to identify the key, especially my working environment lighting is very poor.
Although the part numbers are different, for obvious reasons, the Keyboards look identical. Now, although the keyboard/connections look identical the problem can arise after installation due to the logic board and the logic boards firmware. I have never attempted this swap personally, so I would call Apple or wait to see if anyone here has successfully attempted this swap before spending the $$$ on this keyboard.
Thanks for the information. Has anybody successfully change it ? As my research the logic board is changed with a new plug in for controlling the LED for the keyboard.
