I have a Lenovo Y510P and yesterday morning all of the ports stopped working randomly. I knew this because my mouse stopped working. The weird thing is, my mouse has lights and it still glows blue, even though the red sensor light at the bottom isn't on. So the USB ports are still giving off power. Also, I tried a USB flash drive and external hard drive and both are not recognized. I've done several things to try to fix this, even contacting the technician from Lenovo and we found this: which refuses to do anything or go away. He said that I should do a factory reset, but since my files are still on my computer and I can't back them up (no usb) I don't want to do this. This is also not a hardware issue. Anyone have any ideas on what I should do or how to fix this?
All USB ports in my laptop suddenly stopped working?

Factory Reset certainly will solve your problem because we do not know whether is your driver problem or bios problem or window conflicts or virus. You can use free online storage service to backup your data like gdrive.
Solution
1) Reinstall your drivers.
If still not working
2) Reset your motherboard.
Remove the battery and AC adapter.
Hold the power button for 30 seconds and leave it aside for 10mins.
Plug in the AC adapter without the battery and try power it.
3) if still don't work, it could be virus or other problems.
