my son made fall down the laptop againat school but this time the laptop came out with serious consequences.
Mysteriously the IR camera which nobody has known its existence till today is constantly on, and it is literally burning the chassis. Besides being risky for him or other kids, this will eventually damage the screen; unfortunately I found many guides that disable the webcam but those don't actually turn off the IR Camera since the red led is constantly active.
What I am trying to do is literally to cut the power through some kernel command, if does exist a method to cut down the power to the USB device please let me know! I am pretty sure this excessive temperature is also a symptom of high power usage which meas more power draining and lesser time battery available.
