I don't think the OP ever explained what the case was for or what prompted them to call for support, but they DO have a case number -i didn't see anywhere where they said it was for a known issue that they were complaining about. the whole thrust of their post is that they were prompted to submit their laptop without any explanation given why. to quote:
"...wouldn't tell me what's wrong with it and to me it's working fine."
Sorry didn't explain fully
I do have a case number
