I was having trouble with my Dell laptop and after attempting to fix it myself I gave up and took it to Office Depot. They kept my computer for two weeks and when I got it back all they had done was revert it to original configuration.
They wiped out all my files (even thought I told them that the computer wasn't worth the $300 but the files were) and I lost all my programs too. All it takes to revert to factory settings is to press a couple of buttons and the computer will to that by itself. I certainly didn't need to pay Office Depot $300 to reformat my hard drive.
I complained and haven't received any response. Their sign says, "We fix computers." but they actually break computers.
