    point of interest. My touchpad left and right “buttons” stopped working about 3 months ago. At first I didn’t think much about it, just used a USB mouse. Then I noticed that the entire touchpad started rising up out of the keyboard cover and at the same time, I was starting to have the screws holding the back plate fall out. Long story short, my battery had started to swell and was pushing everything apart. I ordered anew battery from Amazon (Dell conveniently doesn’t carry that part anymore!) and just replaced the swollen one with it.
    Beside my touchpad residing back where it belongs, my “buttons” work again, and, I need to do further testing on this, but my boot time decreased from an average of 65 – 70 seconds down to 27 seconds.

      This exact same thing happened to me.

    The same thing happened to me.
    My touchpad has also risen out of the keyboard cover.
    How much did you have to pay for the new battery?
    Could you still use the old touchpad or did you have to replace it too?
