Hi Chuck
Thanks for your encouragement.
At first I had a Negative Impression of Dell
because of their use of Propriety Parts.
I am not very Knowledgeable about computers, self taught.
After Getting the Precision T 3500 It was so complex
I very much appreciated the very complete user
Manual offered on line by Dell. I solved the problem of the
Propriety Parts by purchase of A back up Parts Machine on E-Bay.
Cheep $ 100 I am sure I would pay more than that for just one Part from Dell.
