How can I alternative a part inside my MacBook air cheaper?
Hello everyone, this is my first time with ifixit. About my macbook air, I can't use number keyboards, it doesn't show 1 2 3 4...., it just show ! @ # $....., and when I press the launch button, the screen shows very slow. I brang it to an Apple store to check, they said that I need to replace something about 450$ but I forgot what they were. However, It's too much for me. How can I check what wrong with my macbook and how I can fix my macbook with a cheaper price? I appreciate with any helps, thank you.
Is this a good question?
