Well You could ask what the firms privacy policy is..
I have this happen on a regular basis.. And if the people Ask we are obliged to tell them.. or atleast show them a copy of the instructions that are given to our techs regarding what they can look at freely on a customers machine with out prior consent.. Which is next to nothing..

But If you don't ask, or the Repair Centre dosen't display some form of privacy statement, you just won't know and they will assume that you don't care either. And if the center has no policy or treats your request as a joke.. Contact the manufacturer and find anothre repair center.. This is assuming a major manufacturer ie IBM, Dell, H/P..


Sorry but no comfort.
