    Here is the issue : when the machine isn't connected to the power supply, the touchpad works perfect..
    when I connect the laptop to the power supply , the mouse cursor goes crazy when using the touchpad... This problem doesn't happen when connecting an external mouse.

    Tried reinstalling touchpad drivers, Tried factory reset windows 8.1... tried discharging battery and then pressing on power button to discharge electricity... nothing seems to work.

    Also Important to note i switched between the HDD i recieved with the machine to an SSD, but for awhile it worked perfectly....

    any ideas what could be causing this problem ?

    Have you tried disconnecting the battery and just using the power supply?

    Can you use a different brick? Touchpads can be quite sensitive to EMI so your brick may have a slight fault and is pumping out interference or your machine is not grounded properly messing again with the reading.

    This could easily be what's happening. If you have a way to test a second PSU please do so and let us know!
