What I do not understand is why dell does not stock their own old parts for their PCs. I called dell for a repair and they said they no longer stock the part but I could search online and find the part through 3rd party companies. WTF? I found ambry and thank the heavens they carried the part. I don't understand why dell doesn't bother with this but I am glad ambry exists to sell it to me and for a really good price.
