W520 left side USB ports are not working.

Hi everyone , i'm running into a problem. I'm trying to use the usb ports that are on the left side, but they aren't working. i plug in my Mouse to one of the USB ports and when i boot up my computer i can see the mouse working since it lights up, but then once the windows screen pops up it turns off and i can't use it. Anyone have any clues? i tried plugging in a USB flash drive just in case it was just the mouse and it wouldn't work either.

Hi SR20SE,

 

Welcome to Lenovo Forums!

 

Try to uninstall and reinstall the USB drivers, to find the same, go to device manager, click on universal serial bus and click to uninstall it. And also please check in BIOS whether the USB is enabled.

 

Please let me know whether the above steps helped you.

Thank you, have a good day.

 

Regards,

Naveen.v

Re: W520 left side USB ports are not working.

i went under the device manager and looked at the USB 's, but there were a few of them. i uninstalled and reinstalled the following : generic usb , generic usb , renesas 3.0 USB host. there was a message that said ,"bluetooth peripheral device not found ".

 

i checked the BIOS and everything is enabled.

 

 NEVEMIND . solution found. i looked under the" other device" option and saw that there was an unknown device that didn't install correctly. i went under " Properties" then went to the "driver tab" .I hit update, and it gave me a warning about installing an unknown device , but i went ahead any way and everything works now.

 

incase someone is having the same problem, here how things should look like when the left side usb's are working and installed.
