Will a computer technician look at my files while fixing my laptop?

My laptop was working fine yesterday. I went out for a bit, but when I came back it just wouldn’t turn on (if anyone knows any reason why this may have occurred advice would be appreciated.) So the thing is, I’m reluctant to get it looked at. I have some personal files on there which are for my eyes only. They’re not bad, but I’d be so embarrassed if anyone else saw them. My laptop won’t turn on so it’s not like I can save the files to a memory stick either. Would a technician be interested in looking at my files, or would he just aim to diagnose the problem?
