According to the memo, Apple has noted that they have identified an issue with the main logic board and that this problem seems to only affect the 13-inch Retina MacBook Air, so if you own Apple’s other laptops, there is a good chance that your laptops aren’t affected by this. The company does not elaborate as to what the problem might be, other than to say that it has something to do with “power”.
However, based on user complaints about the laptop, there have been quite a number of users who have in the past complained about their laptops not being able to turn on. This dates back to when the refreshed MacBook Airs were first launched back in 2018. It is unclear how widespread this problem might be, but Apple is expected to offer support for four years from the original date of purchase, so if you don’t run into issues now but further down the road, not to worry as you should be covered.
