There is a new Dell "end of life" policy for XPS laptop. I have been a loyal Dell laptop user for years. My last two purchases were two XPS laptops. The last one I purchased had to have a repair within 2 years. It is just over 5 years old and apparently needs a new keyboard. I was told that after five years the computer is at end of life status and no parts are available. I bought the XPS with every bell and whistle available making it quite expensive. I never imagined that Dell has this new policy and the expression "end of life" was repeated by several Dell representatives including a supervisor, obviously that is a new mantra. I no longer recommend a Dell. Fortunately my older XPS is fine and I have an old Toshiba over 10 years old that works just fine and a even older Dell Inspiron as well. Because I used the laptops for work I had several for different purposes. The last XPS had the least use and had suffered no falls or other damage. To add insult to injury I was told by Dell to try to get the part from laptop repair services. Tried and was told by several that the keyboard on this particular XPS - XPS15z was found to have keyboard problems and they had exhausted any parts for it. I will continue to post over the Internet the new " end of life" mantra warning others that is no longer worth it to spend the money for an expensive XPS. I do not know if the end of life concept now applies to all of their laptops but I certainly will never buy a Dell again.
