Answer to "MacBook air keyboard and trackpad unresponsive"Hi, I have a MacBook Air A1369 that’s been power off for long time because I don’t have a power cable. I buy a new power cable, MacBook Air power on perfectly but some keyboard keys won’t work. I tried to reset using Command + R but this R key won’t work. I ordered a new keyboard in this page but I don’t see a guide to replace this keyboard. Please let me know where I can find this guide.
