If I've understood correctly you formatted your laptop's hard disk and want to recover files that were deleted in the format. It may be possible to recover some of your files, depending on how much new data was written to the disk after you formatted.
There are a number of free recovery tools available you can try. Pandora Recovery is one, you could start there and see how it goes. Sometimes different tools recover different files due to using different recovery methods, so it can be worth trying more than one tool if you can't recover everything you need with one tool.
