I got a new Y50 Lenovo laptop two days ago and everything was working perfectly. Out of the three available usb ports, I had my mouse, headphones, and CoolerMaster X-Slim fan plugged in. The fan was working well until I started getting power surge notifications in the bottom right, and suddenly the fan stopped functioning. I unplugged the fan from the usb and replugged it, but nothing. I then tried plugging in my mouse to that port, and it didn't work. I re-installed the USB drivers and restarted my computer. I then tried plugging my mouse into that port, and it worked! However, whenever I plug the external fan into ANY of the three ports, the USB port immediately stops functioning for anything. Any suggestions on how to solve this problem? Is there too much electricity going through the computer? Faulty fan? Thanks in advance for the help.
