I'm almost thinking it has to be a software thing since the touchpad and trackpoint are not physically connected. I tried updating my synaptics drivers, updating bios but can't get anything to work, or even show that its connected. trackpoint is not showing up in the device manager or bios. The weird thing is the trackpoint and touchpad do not share cables and the keyboard works fine. It did today, and I replaced it but it didn't rectify the problem. The mouse registers that it has power because the lights on the mouse turn on if you hit a couple of its buttons. I hoped it was just a damaged part so I waited till the new palm rest came in. My Lenovo Mouse isn't working right My mouse suddenly stopped responding when i moved it and the red light scanner for movement is turning on. When I hooked everything back up (including my broken but functional palmrest/touchpad assembly the touchpad, fingerprint scanner, and trackpoint no longer function. I replaced the top case and bezel since my new palmrest hadn't come in yet. The only damage was cosmetic (screen bezel, palm rest, hinges, top case) anyways I ordered the parts and replaced them. But long story short I dropped my Lenovo Edge E420 (5 feet onto concrete). So not even sure this is the right forum since i'm not even sure what the problem is.
