MacBook Lid Angle Sensor Issues in MacBook Air & Pro: Complete Fix Guide
G’day Auckland! Dealing with a MacBook that won’t sleep when you close the lid? Or maybe your screen stays black even when it’s open?
You’ve likely got a dodgy lid angle sensor. I’m Praveen from SMASHED IT, and after sorting hundreds of these tricky sensors across Auckland, I’ll break down everything you need to know.
What is a MacBook Lid Angle Sensor?
The lid angle sensor (LAS) is a tiny but crucial component in your MacBook. It tells your laptop whether the lid is open or closed, controlling sleep mode and screen brightness. Think of it as your MacBook’s eyelids – without it working properly, your laptop doesn’t know when to “blink”.
This macbook lid sensor sits in your screen assembly and uses a Hall sensor chip to detect the lid position. Sweet little piece of tech when it works, absolute nightmare when it doesn’t.
