I have the same rising touchpad problem as reported by at least one more user on 19 July in this forum. Internet search shows that this is a common problem with the XPS 9550 caused by battery inflation.
My 1 year guarantee has expired, but I would like to invoke my 2-year legal guarnatee as this is an error of the producer (having installed a battery that inflates in conditions of normal usage) that came with the product and only manifested itself later.
Please advise on how to proceed.
Could you please send me in a private message de Service Tag of your Dell XPS 9550.
I just sent you right now an invite request of friendship.
Wait for your answer.
Have a nice day.
