As it turns out, there is another change. In an internal document for Apple Authorized Service Providers, which was purchased from MacRumors, Apple states that the 16-inch MacBook Pro includes a new "lid angle sensor" that presumably monitors the opening and closing of the notebook and the exact location of the lid ,
MacRumors turned to iFixit for examination and discovered a small sensor on the left hinge of the notebook. In the hinge itself, a magnet is embedded whose arrow indicates the polarity. iFixit updated its demolition with photos of the sensor we shared below.
While previous-generation MacBook Pro models have a Hall-effect sensor that detects when the sleep / sleep timer Purpose is closed, it is the lid angle sensor in the 16-inch MacBook Pro it seems to be more sophisticated.
Apple's service document gives no indication of why the sensor was redesigned, but iFixit speculates that it could provide Apple with a clever way to keep track of how often the lid was opened, closed, or adjusted when the display or the display does not work Frayed flex cables need to be repaired – think of "flexgate".
The lid angle sensor could also be used for an unannounced macOS function, even if this is just speculation.
Note that if the display is repaired, the Apple Service document indicates that technicians must calibrate both the display and the lid angle sensor to complete the repair. If we get additional information about the sensor, we will certainly provide an update.
