Hello guys,
I'm studying a schematics from a laptop and trying to get better understanding of various parts and their role in laptop motherboard. I'm not trying to fix any specific motherboard, but to gain more knowledge.
It is interesting for me a LID switch on a motherboard. I know it's a HALL sensor and when magnetic material gets close to it, it will switch. So basically it is a switch that opens or close depending how close metallic frame of screen is.
But which circuit (voltage) this switch close or open? I know this can be measure on the power button connector. This switch should cut power to the screen but also do something to send the computer to sleep.
Also, I wonder what accelerometer sensor do in a laptop moterboard. What is its role?
Thank you.
