A newly inherited U430.
The port I am referencing is right next to the charging port on the right side of the laptop. When I plug in ANY device to this port, I get an error message saying something to the effect " Windows does not recognize this device". If I take the same device and plug it into the other USB port right next to this one, Windows recognizes it and it works. I went to Device Manager in the Control Panel and checked every listing under the "USB Controllers" heading. 7 of them. All said that "This device is working properly". Now , when I plug a device into this port, the device (any device) will show a quick blink of its power LED which indicates to me that power is coming through the port. The blink lasts a mini-second and goes out and then I get the error message. Puzzled as to what is happening here particularly when Device Manager shows no conflicts. Upon further examination, I looked closely at the USB port in question, and noticed just under the USB symbol for that port, there is a battery symbol that does not appear on the other USB port next to the port in question. What does the presence of the battery symbol under the USB symbol indicate? Looks like their is a difference in functionality between the two ports. Am I correct? Appreciate your thoughts.
