|Rule number one...if you ever send your PC back to the manufacturer to fix something, always save all your files etc before sending it out. They should have told you that, because they just take the quickest and easiest route, reformat and put the PC back to the way it was when you bought it. It's a lesson learned.|
The weird thing about that is that 99% of the new HP's have a hidden partition and some allow a non-destructive repair of the operating system from the partition. That would have saved all your files and documents, etc.
Recuva might find your documents and pics to recover, it is free and try it NOW before you load on too much stuff on your laptop....the more you add, the less chance of recovery. Good Luck
