I received my XPS 15, 4 years ago The good; the battery lasted 4 years... it's all downhill from here... Went to order a new battery since mine had begun to swell (can eventually explode and burn your house down). I'm a little more understanding considering the age of the computer and battery but batteries should not be swelling and breaking interior components within 4 yrs. The first time I got on the phone they told me they could send someone to fix it for me, at the price of $450... no thanks. So I took matters into my own hands, go ahead and buy a battery and replace it myself. I must have called on 4 different occasions (each time included at least a 15 minute hold and a series of people who seemed to only want to pass you on to the next person). The shipping info and the first person told me I would have the battery within a week and a half... okay, not bad. I checked the next day it tells me it won't be in until a month and a half later. However, every time I decided to check, I would end up with a different date. I called multiple times to see when I could expect my battery as school was starting and I couldn't just sit around with a paperweight of a computer. No one could give me an answer. I was told I would be contacted within 24hrs to let me know when I could expect my shipment... nothing. Called once more today and the gentleman on the phone seemed very sorry with the my experience, he told me to continue to wait a couple more days. I decided to cut my losses and cancel the order to get a battery elsewhere. He did inform me that they have a shortage in the specific battery model I need (probably because everyone else's is also on the verge of catching fire as well). Would have been nice to know there was a shortage when I had first called so I could have gotten a battery from an alternate supplier by the time I made the call to cancel my order. I have loved my $2 300 machine but it sure isn't worth the headache of trying to get an alternate part for it. One thing can be said from this... my next computer will sure as hell not be a Dell, their "customer service" will regularly have you pulling your hair out.
