We purchased an ex-school Acer laptop that the USB2 ports were not working.
I pulled it apart and found that one USB socket was part of the motherboard and the other was a separate circuit with the power switch
I tried looking up the USB sockets but couldn’t find them, so repairing is the only option
So after reassembly the motherboard port worked but the one on the power switch did not. I’ll get around to pulling it apart again another day to fix it again
