I've recently purchased a M6500 refurbished. The OS is Windows 7 64bit. The problem I'm having is the mouse for no specific reason will sometimes not move right when using the touch pad. I've installed the synaptic drivers, Dell drivers and followed a couple other suggestions from the below thread.
I have also performed a clean installation using just the drivers listed for this service tag from Dell's site. This fixed the problem for roughly a day but now its back to acting up. Not as much as before but still not acceptable. I've pasted a video of the exact problem and a rather lengthy thread on a Dell forum about this type of problem. I'm hoping this can be repaired without parts replacement. When using an external mouse or the touch stick all is well. Thanks in advance.
