RE: XPS 15 9550 touchpad issue that Dell apparently can't fix

I am going thru this exact same problem with an XPS 15 9530.  I bought it thru costco and it is less than two years old so they are handling thru their concierge service.  Once it got to their repair facility, they said the touchpad is being elevated because the battery has swollen and is pushing up on the touchpad..  they are supposed to have it back to me by the end of the week.   i will let you know the results when i get it back.
