Unable to connect USBs to Lenovo Yoga Pro 3

2015-05-15, 11:36 AM

I just bought a new Lenovo Yoga Pro 3 and I'm unable to connect any USB sticks or my external harddrive to the computer with a USB cable. I've tried both USB 3.0 ports on the computer and I've tried USB 2.0 and 3.0s. Does anyone have any idea how to fix this?

Thanks in advance :)

Re: USB ports on Yoga 3 Pro not working

2015-05-19, 14:15 PM

I have had the USB issue again evern with the recent BIOS update (50) - so I reset my BIOS to accept re loading of earlier versions of BIOS, re installed version 49 and re booted - USB ports all working again. Upgraded back to BIOS 50 and again all working fine. Issue occurs whenever I unplug anything from a USB port without disabling it first - this includes printers with their own SD / USB ports

 

Hopefully someone in Lenovo will sort this out soon

I have now re loaded an earlier BIOS version and then upgraded to the current version 3 times and it solved the problem each time  - so for me it is a work around until Lenovo sort it out.

 

Since then I have loaded USB Safely Remove Software - I deactivate anything attached to a USB port using this software and so far no crashes since then

Hi all-
Let me report my situation and summarize the solution.

Some people say that restoring back to the factory setting may solve this issue. I tried this but it did not help at all. Some also say that they solved this issue by sending the laptop back to the depot service center. I tried this but a senior technician that I talked with said that he could not find the symptom. That being said-- when my lap top arrived there in the center in Texas, the problem disappeared. So nothing has been done and it was just returned. I tried bunch of things but I will follow what GMF said above.
I just received the earlier version 49 from him and allowed my bios set up to be able to go back to previous version and re-installed the version 49. Now USB works fine. If my battery problem happens again, which led to update the bios to the version 50 in the first place, then I may update it to the version 50. But, then, I will cautiously use "remove USB software" as he recommends.

I have sent my laptop back to Texas Service Center three times in the first 4 months after I purchased this product. What is more frustrating is Lenovo has not perfectly fixed this issue so far. Now it is clear that this USB port problem is software issue (I sometimes doubted whether it is hardware issue since the problem started after they replaced my motherboard and bottom plastic body for another problem)
Do not try anything else but I would recommend down-dating to previous version and see whether USB works again. Probably, we should keep doing this until Lenovo solves it.

I've had the same problem and do not know when lenovo will come out with the solution. Kind of frustrated with this sort of problem since this product has been out in the market for a while already. BTW, just found out today that when all my usb ports are engaged with something and power is down to 10%, all I could notice is my pointer, which I moved with a mouse,  just suddenly gone static after I plugged in the power cable. I think it's a power-related bug. Just hoping if anyone has signs like this too.
