I immediately formatted and reinstall the system, because no one should ever trust a third party. Some keyboard keys have some issues, and a laptop itself to kind of smelled of potpourri Aunt perfume. The power adapter was not genuine Dell.Otherwise everything works well for a system that will never connect to the internet. I needed something to use with my automotive stuff.This seller did have custom software or something on the install. I did not investigate because I was going to reinstall Windows anyways.
