I had the same problem (2 months out of warranty). It was the bulging battery. Ordered a replacement from Amazon and replaced it myself. Everything is fine now.
Super annoying to have paid over $2k for the MS Signature edition and this happens just over a year later. I've actually sent mine in twice for other issues while it was still covered under warranty. I've bought several Dells in the past, including my last three laptops, but I think I'm done wit Dell after this.
While I don't have an issue with the touch pad, it is clear that my problem is also related to the battery swelling.
I purchased a Dell XPS 15-9530 in September 2015. I had decided to spend the extra money for that laptop thinking that surely it would be of a high quality and standard. It was great to start with, but after a while - actually just after the warranty ran out like many other users here - it started developing bubbles on the palm wrests and the edges seem to be lifting. Also it is getting hotter than it used to when editing video. After a bit of searching I have ended up here, only to be totally disheartened that the problem is so prevalent and Dell do not seem to really care.
This laptop was not cheap. The support and updates for it have been very poor to say the least. I now regret spending all that money and have completely lost faith with Dell.
I have the same problem. Just called DELL support and same strategy - "I have nothing about this issue in our systems and I do not have time to read forums". Guys - this is a design flaw. Next time I go Apple although I wanted to avoid Apple on the Laptop front.
Same problem on my XPS 13, purchased July 2015, still under 3-year warranty. Swollen battery pushed up trackpad, the first Dell engineer didn't spot it so replaced the trackpad, the second recognised it as a battery issue and removed it but Dell haven't (yet) approved a third repair to replace the battery. I don't think they will because the battery isn't included in the warranty, and I'm not sure they even have any batteries - perhaps in recognition that they're faulty and don't want the liability of selling them directly? Their approved supplier also doesn't sell them.
Woah, I have this problem too but I didn't know it was from a swelling battery. Of course, the touch pad being so hard to click is annoying but now i'm more worried about it exploding or something if I push to hard on it.
I must add to the string. I have a XPS 15 9550, went out of warranty January 2017. Pad got progressively worse and sometimes stopped working, over time I noticed the pad was not flush and it got steadily worse. Now it is raised 7cm on left side, 5 on the right.
Has anyone at Dell acknowledged this design flaw? Has anyone had success getting Dell to cover the repair with devices out of warranty?
I just realized that I have that problem as well with my XPS 15 9550 FHD that I bought in December 2015. I called Dell and explained the problem and mentioned that this seemed to be a recurring issue with this laptop caused by a swollen battery. At first the Dell support person did not think it was a battery issue and if it was, I would have to pay for it. But he apparently checked with someone else and came back telling me to send it in and they will replace the battery or whatever else would be needed. I have a two year warranty so the laptop is covered but the battery supposedly is not. However it appears they are now well aware of the problem and it looks like they may replace it for free. After I talked to the support person, he wanted me to stay on the line so I could talk to his supervisor. The supervisor tried to calm my concerns about this laptop and if it happened once will it happen again. I think they really need to do a recall on this thing. I will update later. This PC looked wonderful when it was first released, but with all the BIOS and driver issues and then this, I may start looking for something else.
Swollen batteries are an issue with all devices that use batteries not encased in steel -- that is, in just about everything that uses prismatic batteries wrapped in foil rather than cylindrical cells encased in steel. There are still systems that use the older battery types - these generally have removeable, rigid-cased outer shells. It's not possible to design a system as slim as the XPS with these cells.
Apple has had problems with swollen batteries for years - because they were the first to use them. The PC world followed suit, and the problem is now following PCs as well - along with cell phones, and other devices using these batteries.
I suspect that just as most cell phone users are becoming used to having to replace batteries after about 18 months, so too will slim-notebook users. The batteries are run at the edge of their endurance, in a hot environment and subject to being drained by high-power components. Manufacturers are cramming more and more power in to a smaller space. Doing that pushed Samsung over the edge with the Galaxy Note 7 -- but since there's nothing available commercially to replace lithium ion/polymer cells at the moment, if you want thin and light - it's going to come along with regular battery replacements.
