I have a Lenovo x240 with Lenovo USB 3.0 Dock (port replicator) and Lenovo Ultraslim Wireless Keyboard and Mouse. The keyboard and mouse work fine when plugged in to the laptop directly, but not when I plug in to the USB Dock. The keyboard will work most of the time, but the mouse jerks around and is slow to react when clicking the buttons.
The point of the dock is so that I can just plug a single cable in everything just works (keyboard, mouse, network, monitor, printer). Everything else works, except the keyboard and mouse.
Does anyone know why this doesn't work and how to fix it?

The issue is with the docking station. USB wireless receivers do not work well on them. The problem resides within the USB 3.0 hardware causing interruption of the usb wireless signal.
An extension cable may work. It will get the wireless receiver further from the USB 3.0 signals.
If this does not work then you must plug the receiver directly into the laptop or use a wired laptop and mouse into the docking station. Other options are to see if you can find a bluetooth keyboard and mouse as they will work as well.
