This video shows how to replace battery but all you need to do is disconnect it at beginning of the video.
* Reset BIOS by disconnecting CMOS battery:
1. Unplug charger then unscrew and open the back of the laptop (''see above video'').
2. Locate the battery wires and unplug the battery wires
3. Take out/disconnect the CMOS coin battery (a small metallic cell possibly enclosed in black heat shrink)
4. Press the power button for 15 seconds continuously to drain the remaining power
5. Place the CMOS battery again
6. Plug the wires of the main battery again. Note: ''You could try not connecting it and try running the laptop on just the charge. Bad batteries can do strange things.''
7. Place the cover back and put all screws
8. Power on
9. If it does not power on press and hold the power button for about 30 seconds and then press again. It should turn on now.
Let us know how it goes.

* Motherboard Usb Host Controller Count：1

* Motherboard Rtc Test: Warning (CMOS)

CMOS has became the wide spread word for RTC so there is no difference.

This may explain your problem. Bad CMOS (see I'm doing it too!) batteries can cause all kinds of strange problems.

Usually about $2 or $3 to replace. Beats a new motherboard for $212- $300 which could still be the problem but I doubt it.

Oh and did we also check from the BIOS if you can see any USB drives plugged in to the USB port?

These steps are to eliminate possible causes of problem:
* Go to the Lenovo web site and run the Diagnostics:
https://pcsupport.lenovo.com/in/en/products/laptops-and-netbooks/lenovo-v-series-laptops/v310-15ikb/diagnostics
Record what they suggest and get back to us.
* Download BIOS update (if you haven’t already done this). Read directions:
https://pcsupport.lenovo.com/in/en/products/laptops-and-netbooks/lenovo-v-series-laptops/v310-15ikb/downloads/ds118614-bios-update-for-windows-10-64-bit-notebook
