Recently my laptop USB ports suddenly stopped working. I can't plug in any device since it won't recognize anything and the ports also don't work in the BIOS. I can't even charge my phone so it doesn't give any power at all. Is my motherboard broken on my laptop or is it a software issue?

Yes, i don't know how only the USB ports are dead and all the other ports like LAN and HDMI still work. frustrating :S
 
You have a power switch (G547E) who control the 5VDC for just the USB ports. This chip receive a signal from the Embedded Controller. If this chip (G547E) did receive the signal, it must be defective, because it did not give the 5VDC to the ports.

So (5VDC) controls the USB ports and (G547E) gives it power? If (G547E) is dead the USB ports won't work?
 
You are sure you don't have any power from the USB port on the right side, because the power does not come from the same chip. All USB ports receive the signal Power On from the Embedded Controller. The two from the left side receive their power from the G547E, but the one from the right side, I don't know what chip gives the power, because it's on a small PC board and it's not on my schematic.
