Apple’s 16-inch MacBook Pro will have a mysterious new ‘lid angle sensor’

Earlier this week, do-it-yourself repair website iFixit shared the full teardown of new 16-inch MacBook Pro, providing a closer look at its new thermal architecture, scissor-switch keyboard, and other design tweaks.

As it turns out, there is one more addition to the device. That is, in an internal document to Apple Authorized Service Providers, obtained by MacRumors, Apple indicates that the 16-inch MacBook Pro includes a new feature called “lid angle sensor” that presumably monitors the opening and closing of the notebook and the precise angle of the lid.

MacRumors reached out to iFixit to investigate, leading them to uncover a small sensor that is facing the left-side hinge of the notebook. There is also a magnet embedded within the hinge itself, with an arrow indicating polarity. iFixit has updated its teardown with photos and videos of the sensor, which we’ve shared below.

While previous-generation MacBook Pro models have a Hall effect sensor that determines when the lid is closed for sleep/wake purposes, the lid angle sensor in the 16-inch MacBook Pro appears to be more sophisticated.

Apple’s service document does not provide any clues regarding why the sensor was redesigned, but iFixit speculates that it could provide a clever way for Apple to track how often the lid was closed, opened, or adjusted in cases where the display or frayed flex cables need to be repaired — think “Flexgate.”

The lid angle sensor is also an unannounced macOS feature, although again, this is merely speculation.

Of note, in an event of a display repair category, Apple’s service document mentioned that technicians must calibrate both the display and the lid angle sensor in order for the repair to considered complete. If we learn any additional information about the sensor, we will update the information ASAP. Follow the articles.
