Re: USB ports on Yoga 3 Pro not working

2015-12-20, 23:29 PM

I have been following your updates regarding installing new/old version of BIOS.  I have figured out how to get into BIOS but not sure how to install the 56 version.  I also noticed my touch screen has also stopped working.

 

Any guidance would be appreciated.

Shelley

Re: USB ports on Yoga 3 Pro not working

2016-01-05, 2:12 AM

I have the exact same issue on the Yoga 2 13".  

 

USB 3 devies work on USB 2 port.

USB 2 devices work on USB2 and 3 port.

USB 3 devices, like my 128GB USB drive, my Diamond USB network card  USB303HE.  and several other devices. 

However a Cable Matters USB 3 network card seems to work fine.


Expecting this is a driver or chipset issue?  Lenovo actually replaced my System Board. now my Fan is quite but still USB 3 drops constantly.

 

Lenovo, do you guys look at these things?

Sooo.. USB, SD  and touchscreen wasn't working.. .can't remember if I tried BT or not.

 

Wifi was working (poorly, as usual .. check the community forum about Yoga's wifi performances...)

 

I finally lost patience and made a fully system recovery.

 

Fortunately all my data were on a NAS.

Still .. I had to reinstall everything.

 

now it's working fine.

I still don't know what happened, so I use Onekey recovery to make regular backups, I'm not sure it wont' happen again...

Correction:

I have the exact same issue on the Yoga 2 13".  

 

USB 3 devies work on USB 2 port.  = work

USB 2 devices work on USB2 and 3 port.  work

USB 3 devices, like my 128GB USB drive, my Diamond USB network card  USB303HE.  and others = DO NOT WORK.

However a Cable Matters USB 3 network card seems to work fine.

Re: USB ports on Yoga 3 Pro not working

I figured something out.

 

The USB ports stop responding whenever I unplug an external-powered USB hub. The devices won't even light up, and I can't boot from an external USB drive. Flashing the BIOS is no option for me because I'm on Linux (I could have tried booting from a Windows 8.1 SD card, but meh).

 

The easiest solution for me is:

1) Drain the battery completely, so the laptop doesn't turn on, and remove the power adapter

2) Press the power button 10 times every 1 second

3) Press it once more, after 1 second, and keep it pressed for 30 seconds

4) Plug the power adapter back in

 

That makes my USB ports come back to life.

The problem is with the Hardware, NOT windows.

 

The first time I encountered this was 2 days after my warranty passed...brilliant...call me paranoid, but I'm pretty sure this was by design...anyway I'll move on to the solution.

 

I've since have this happen 3 times, all of which I followed the instructions below to resolve the problem...

 

SOLUTION: (if you can call it that - Lenovo fix the issue with the BIOS!!!)

 

So, when it happens...

 

1) Download the latest BIOS from the Lenovo site and save to a folder called C:\BIOS

Don't delete it afterwards you like may will have to use it time and time again when this happens.

https://download.lenovo.com/consumer/mobiles/a6cn58ww.exe

--> A6CN58WW

 

2) Shutdown the machine

 

3) Press the BIOS button on the right hand side of the machine (inser concave button), next to the power button.

 

4) You'll be presented with menu, choose BIOS setup

 

5) Find the BIOS option, to flash previous versions and enable.

 

6) Save settings and reboot

 

7) On rebooted and in windows, run the EXE downloaded above [Ensure you have your power cable in]

It will auto reboot

 

8) Wait for the system to flash/re-flash [I use the same BIOS version again and again]

 

9) It will then boot up and you should now have your USB's working again.

 

This happens to be about once a week, so I'm tempted to try and get what is called an "Uplift" code off Lenovo so I can take it back to John Lewis where I bought it (least there I have a 2 year warranty).

 

Good luck guys'n'gals hope this helps.

 

Karl
