Hello nairalanders. Pls I have a couple of laptops that I v been using for year. I have the different systems for different reason. But I recently observed that the USB port are wearing out. It either connection isn't established or the transfer rate of files is slow and other symptoms. Pls who can fix or replace USB port on laptop well. I understand it's a very sensitive repair cause some of the laptops (especially mini) have the USB port on the board. Pls help
