No power in the USB ports or possible burn out
I recently started using a USB fan(such as this but not exactly this http://www.cdrking.com/apanel/module...rge/1325_1.jpg ) to cool my laptop because I found it more efficient than a cooling pad. After a few days, the fan started to have problems such as dead LEDs and some grinding noises started to come up. I remedied the noise problem by putting some lubricant. After a few more days the USB fan looked like it lost power or is losing power and the lights of a USB mouse plugged in next to it started to flicker and was getting "unplugged" meaning the "removed device" sound played. Then suddenly, I heard a "click" sound near the USB ports. The fan was off and the mouse became unresponsive. I check if it smelled like smoke and it did. Even the USB 3.0 port on the opposite side of the laptop stopped working. All three available USB ports are dead. But, when I tried to reattach the USB mouse and the light flashes on for a split-second but it doesn't fully activate. USB Flash Drives do not work as well but a printer the I tried to plug in worked probably because it's individually powered.
