USB ports on Yoga 3 Pro not working

2014-12-30, 3:58 AM

This morning all of the USB ports on my Lenovo Yoga 3 Pro (running windows 8.1) stopped working. They don't detect devices, nor do they charge devices I plug into them - Iphone, mouse, keyboard, flash drive, etc. I've run windows update, reinstalled the intel chipset driver, uninstalled and reinstalled the USB drivers, ensured they are not being turned off by the power management system, and even run the Lenovo Solutions program (which said the USBs are working fine).  I've even done a system restore to a time when they did work - still nothing.  I'm out of solutions!  PLEASE HELP!

Thank you!  I used the Novo key at startup to get into the BIOS, then reset the settings.  When the computer rebooted, all my files and programs were fine BUT my USB ports were working again.  Thank you!

All the USB ports are not working on Yoga 3 Pro, first check if the USB ports are enabled in BIOS option. If it is disabled then enable it and restart the computer, and check if USB ports are working. If this does not resolve the problem, then try Fix it tool from Microsoft. It will fix the USB problem automatically, click the below link. Then click Run in the File Download dialog box, and follow the steps.

If this also does not resolve your issue, then there might be some infections which can cause problems with USB ports. Scan your PC using antivirus and check you can access USB ports.

I have the same issue on my new Lenovo Yoga 3 Pro.

 

Suddenly all USB ports stopped working.

I have tried your solution and resettet the Bios but it still not work.

 

This is no driver issue; if I want to boot from some USB storage the USB device doesn't show up in the BIOS and the status LED on the USB device doesn't light.

 

Is this a general problem? Is there a fix?

 

I payed over 1500€ and can't use USB devices. Please help me.

 

Thank you.

Hey,

I have the same problem. All my usb ports are not being detected.Tried various solutions like restoring the bios and also a system restore. Both seem not to work. Is there any fix for it or a work around.

 

Thank you

Hi There,

 

Same problem. All USBs have stopped working.

Is there a fix for this apart from doing a system restore?

Hi Asish,

 

Yep. Same as you. Rebuilt/reset (via the novo button) still no USB ports, so Lenovo are coming are collecting for a hardware repair. Bummer.

Did your SDXC port go down with the ports?

Hi Andycai,

 

What level did you apply?

I was at the following BIOS:

 

Flash BIOS update - Flash from Operating System version for LENOVO YOGA 3 Pro
Version A6CN47WW (19-Jan-15)
Applicable OS Windows 8.1(64-bit)

 

I shipped it back to Medion on Friday, I will keep thread posted.

 

Regards PB
