My laptop has a USB issue. Ports E and D support data transfer and charging. The third port (second from front in the attached image, with the usual USB symbol) only allows charging. Please advise on possible remedies.

    First blue USBa3 port supports both power off and power on charging of devices plugged into it.
    Second blue USBa3 ports supports only power on charging of devices plugged into it.
    Both ports should support USBa3 sticks but sometimes have issues with older USBa2 sticks

    If second blue port does not see data on a USBa3 (NOT USBa2) stick or input from a Mouse dongle, try a different USBa3 (NOT USBa2) stick or mouse dongle. If it still doesn't work then the gold-colored contacts inside the port are likely dirty and should be cleaned with a Q-tip moistened with rubbing alcohol.

    Definitely sounds like a bad, cracked or cold solder joint in the port's mainboard connection. Probably the only way to fix this is to remove and strip the mainboard of all heat sensitive components and do a solder reflow either with a heat gun or full board reflow in a toaster oven. A risky procedure with high potential for collateral damage to an otherwise functional machine.

    If it was mine, I definitely wouldn't risk it. I would rather purchase a  USB3A hub for less than $20 to use the existing functional port if I needed more USB3 ports, However, if you want to take a chance, there are videos on disassembling the laptop and removing the mainboard. Google search f5-573 disassembly for what you'd be up against. It's not a trivial process.

    Hi Jack,
    I tried the items you suggested. No success. My disk manager snip is below.
    The malfunctioning port is not showing. I have used a new thumb drive for the test which works fine on D and E ports.
    Could it be a software issue associated with the malfunctioning port?

    Yes! Please post a screenshot of the expanded USB controllers folder in DeviceManager if possible.

    No, sorry. Just click on the DeviceManager's USB controller folder + or > expansion symbol. Just want to see how many controllers show up like shown below. The image is from a laptop with 2 good USBa3 ports

    details of "greyed out" drive

    Suggests a hardware failure. I'm gonna guess a cracked soldered joint or three on the mainboard since the port is stressed every time something is plugged in to & unplugged out of it.

    To confirm a hardware issue, try this. Right click and try to enable the device driver. If enable option is greyed out, then uninstall  the driver. If that's also greyed out, then yes the port's data  i/o circuits are dead.

    If you can uninstall the driver, do it. Then shut down Windows normally. Then re-start and see if Windows can detect the hardware. If not this further confirms the data i/o circuits are dead.
