Tried a complete reset of the OS, but that did not help. I also reset the BIOS and looked for BIOS updates. Nothing helped. Either this is hardware, or Lenovo need to release a ned BIOS adressing the issue I suspect...

Re: USB ports on Yoga 3 Pro not working

I have had the same problem with my USB ports. sent my Yoga 3 1370 Pro to Germany, was told by the UK Lenovo team that they would not repair it as I had bought it in the USA. So computer came back and for some reason the USB ports did work! So today I was using a USB stick and suddenly the USB ports stopped working again - so thinking this might be a BIOS issue I re-installed an early version of the BIOS update from December, re booted - USB ports working again! So hope someone from Lenovo "support" is reading the blog GMFUK

Same here, Checked Bios - enabled for boot, ended up restoring system, Still no joy. Figure I have a hardware issue - which is great because I am in Africa  and nowhere to repair until I return to europe at end of month. Also not sure how to get work done for clients as no USB ports and my software relies on a Marx Dongle.... Not impressed for a machine that is barely 6 months old. 


BTW I did have same isse 2 weeks ago, but same as others. Shut down for the day and when back to it the next morning everytihning OK. Tried this too today, but no luck on that either. If anyone comes up with a no-send away fix would be much appreciated gtting the info. Tried everything in the previous posts.

 

Cheers

What I have noticed when it came back, the BIOS is/was at a6cn47ww 19-Jan-15 which is not the latest version.
Latest being a6cn49ww 27-Mar-15
I'm too nervous to upgrade as has been working fine since Lenovo returned it.
They said it was software and not hardware. So why did they want me to return?
Try both BIOS versions and see how you get on. Latest is on website. If you can't get hold of the older version, a6cn47ww 19-Jan-15, I can mail.
