My daughters Dell Lenovo 5050 Laptop suddendly refused to let her log on so after much faffing I reformatted the hd and returned the machine to factory settings using the option in safe mode. Prior to doing this I was directed to back up documents etc using the the programme which was all part of the return to factory settings mechanism. Laptop now works fine but I cant restore the backed up files. They are all present but cant be opened individually cos they are saved in different file format. At the top of the list there is a file with a small green icon which promises to restore the files. I followed the instructions to restore the file to original location. After about three hours of restoring the files were not restored.
