Ditto. My XPS15 died after 5 mos. Hard drive and motherboard had to be replaced (under warranty, but Dell would only provide a refurbished motherboard). 2 months later, same thing happened. 5 mos after that, same thing again. After hours of over the phone troubleshooting with technical support (with people with poor command of English) and 2 home repair visits, Dell finally agreed to examine it at their repair "depot" (but absolutely refused to replace the computer). It's been working ok now for a few months, but I use it with the assumption that it could die again at any minute. I will not buy another Dell.
My current XPS 15 is 14 months old. It’s on its 4th hard drive (hard drive has been replaced 3x) it’s on its 3 motherboard, it’s on its 2nd battery and 2nd AC adapter. The only thing good I can say about the company is I like that with the warranty I bought they will come to my home to fix it.
The trick with Dell is to buy only their business lines of PCs. Their consumer lines are only marginally better than HP PCs.
