E732z right usb not working

An E732z eMachine is a laptop computer. If a USB port is not working, it may be broken from the motherboard. Laptop motherboard repairs can be very challenging, often impossible if you don't have the right equipment or experience. You may be able to find dis-assembly information/instructions, however if the part itself is broken, you may have issues finding parts given eMachines less than adequate documentation for their computers in general.
More often than not, a complete removal of the motherboard is necessary to work on it. You must observe static electricity precautions. You should have experience with surface mounted devices and know that permanently damaging a motherboard is very easily done without the right experience working on them.
