It doesn't matter because I can't prove anything, but I hope this helps somebody.Īlso, I'm sure the reason my 3rd usb port, the one on the left side of the computer, worked because it hooks directly into the motherboard, so in theory, any usb ports that operated remotely on a chip separate from the mother board could encounter this problem. When looking at this image the usb ports with the chip, are at the bottom right hand side of the picture, simply follow the cable to where they plug in, and thats what I had to plug back in, apparently it got dislodged part way or when I got my laptop back from repair it hadn't been done correctly. Here is a picture to hopefully make it easier to understand.
So after months of fustration and research, I did it the hard way and went looking for a physical solution myself. All I had to do was unplug it, and then plug it back in apparently. And there is a "cable" that runs from those usb ports to the motherboard of the laptop. I had to take the cover off of my laptop (the piece of metal around the keyboard that has the touch pad built in). I will simply give the short version of this fustrating situation. I recently had a problem with my HP Pavilion dv7t-4000 where the two usb ports on the right front side of my computer would provide power but not recognize anything that I plugged in, therefore nothing would work. Please provide any suggestions that you have for me, I really don't want to reinstall the OS, but if that is my only option then I'll have to do it. Backing up all files and reinstalling the OS? Replace the HD with another HD and see if the USB ports are working with the new OS on the new HD?Ģ. I'm wary to think that the ports are dead as they are still providing power and the no diagnostic is finding a conflict or issue with the ports.ĭoes anyone think that any of the following things have any merit?ġ. I'm at a loss, and do not know what to try from here. Ran Dell Diagnostic utility and no issues found with the USB ports or controllers
Installed a logitech mouse driver which is the same as the mouse installed. Uninstalled all USB Controllers and rebooted. Uninstalled all USB Root Hub Devices and rebooted. Attached 3 USB flash drives to each port and they were not recognized either.ģ. Attached Mouse, provided power but did not recognize the device. I tried the following to help resolve the issue:ġ. However, all devices are provided power through the ports, and all of the devices work on other computers. I then attached my Maxtor 4 Mini USB External HD and noticed that my USB ports no longer recognized devices that were attached. I eventually forced the computer out of Stand By mode by clicking the power button and typing on the keyboard at the same time. This started occurring after my computer refused to come back from Standby Mode.
The 4 USB ports on my Dell Inspiron 9200 (running Windows XP Home SP2) no longer recognize any USB devices attached.
