Excellent guide. Thank you.

I just wish I read it before stripping down my MacBook last night.

At least I know what screws go where when reassembling it with new hinges.

Excellent guide, thank you very much.

Logic board removed from my daughter’s Air, cooked for 8m at 200C, cooled, reinstalled, and now works again.

I was able to remove and replace the 5th heatsink retaining screw without moving the antenna retainer.

Cheers, Aidan

After installing the backlight I cleared the Nvram but that did not enable the backlight; i was still getting the ‘non functioning’ symbol when clicking F5 or F6.

I then went to System Preferences -> Keyboard and unticked ‘Adjust keyboard brightness in low light’. Then it worked.
