My new YOGA 720's usb port is not working and some told me to update the BIOS.  some say dont.  what can I do on my own to check the port.  I tried a wireless logitech mouse that worked briefly and when I noticed it wasn't working i plugged in my android and it did not register or charge.  any ideas?

Hello  Bkeller810

Thanks for using the Lenovo forums.

It`s a good idea to keep the BIOS update as a last resort option, as that can easily brick your unit if not done correctly.


Try a static discharge for this this has helped with USB problems in my experience, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal


Make sure that your drivers are up to date like the Chipset drivers, you can find them on the support page:



Hope this helps, let us know how you get on.
