I have a Dell Latitude 5511 laptop, and lately, a faint but clearly audible electrical (crackling) noise comes from the motherboard, similar to the random clicking coming from a mechanical hdd's heads moving inside it.
The laptop shows no signs of malfunction, and clearly this is electrical not mechanical, so my suspicion goes to a dodgy component in the power rails (a capacitor or a coil?). I fear this could develop into a serious damage.
Any advise on how to narrow it down?
The schematic is available here:
