What is the reed switch for?
Just curious, but what does the reed switch do? It's the one on top of the optical drive. Thanks in advance.

a reed switch is a sealed glass tube having ferrous contacts inside it.. these reed strips are stiff such that in the absence/presence of a magnet nearby it opens/closes thereby breaking/completing the circuitry... like bernie said we cannot close the strips with any mechanical arm or anything.

The reed switch controls when your computer sleeps or awakens when opening and closing the lid of your Macbook.

I reckon it's activated by a magnet inside the right side of the lid? The switch is a sealed glass tube with contacts inside and there's no way to close/activate them directly with a mechanical arm or tab in the lid.

Yup, the magnet is what activates and de-activates the switch.
