Some odd things, the computer was named as if it  was a tower, not a laptop, I'm doubtful the refurbishing tech did a good job, looked like it was rushed, a lot of junk files left on it.The strangest thing is, each of the Dell power supplies that have been plugged into this laptop now no longer work and they were being used  and  working before I plugged this laptop into them. I'm afraid to try any more fearing they will all be ruined.  I have bought Dell computers for my last 6 computers. I retired from being tech support/trainer 12 years ago so I'm somewhat knowledgeable, though now way behind  times.
