Dell sells computers to third-party sources with their Dell warranty. The third-party source (PConline365) changes Dell's original configuration. In my case they swapped out Dell's 512 GB SDD for a defective 2 TB SDD. When my SDD failed, I learned PConline365 does not offer any warranty. Nor does Dell offer a warranty on parts PConline365 switched out from Dell’s original configuration. Buyer loses. Buyer beware. Amazon, please don't let this continue.
