In all other MacBook and MacBook Pro models with a retina screen released since 2012 when a customer has demanded a replacement of the battery, Apple has replaced the entire top cabinet, including the keyboard and trackpad. This is because the battery is glued to the top case of Mac notebooks with Retina monitors.
The new MacBook Air battery is still glued to the top case, the aluminum frame containing the keyboard and control panel, but Apple will allow Genius Bars and Apple Authorized Service Providers to remove the battery and reinstall a new one without top cover is required.
When the new battery is installed, it is necessary for technicians to add the notebook to Apple's existing iPhone display press tool to enable the new adhesive. The adhesive strips are exactly the same as those used for iPhone batteries.
The trackpad of the new MacBook Air can also be replaced individually, according to the Service Readiness Guide, obtained from a trusted source.
For a closer look inside the notebook, we have to wait for the iFixit tears down the new MacBook Air MacBook Air but Apple has thought to make design changes that allow Genius Bars and Apple Authorized Service Providers to get more Du can easily replace the battery and control panel, which eliminates the need for a full print of capital letters.
If there are any design changes, Apple will probably not expand its new method of replacing the battery of existing MacBook and MacBook Pro models with Retina displays, but it's probably possible with next generation models.
iFixit has self-tutorials for replacing the battery in the MacBook and MacBook Pro models with Retina monitors that require you to purchase the battery replacement kit, but the process requires some work and a gentle hand. Do-it-yourself repairs also invalid Apple's warranty.
By comparison, the previous generation MacBook Air has a disassembled battery that can be removed and replaced by Apple and its service providers.
In related news, Apple also states that replacement of the Touch ID button on the new MacBook Air does not require a replacement of logical card, but the notebook must pass Apple diagnostics for the repair to complete.
Apple replaces the entire top case for a single battery exchange has always been a point, and this change should be well received by the repair industry. It's also better for the environment and will probably save Apple money, so it's a win-win win. We have reached Apple for comment.
