I'm using my T410 Laptop for almost a year now. Last Wednesday (February 23rd, 2011) suddenly the mouse usb port on the right side of the frame didn't work anymore. It did perfect the day before! To check the usb port, I tried other mouses and a USB stick and I restarted my PC, but nothing helped it just didn't react anymore. The mouse works perfectly when I plug it into the usb port on the left hand side of the frame. Does anyone have a workaround to reactivate the right usb port? It's my work PC and I couldn't miss it for 3 or 4 weeks for repair.
