the short answer to your question is "No", in order to decrypt any file depending on the encryption process implemented, you would need either "a private key" or both parties will need the "public" and the other should have the "private"; I advice you not to have any one scam you into saying that this is possible because unless you have a similar system that was using this type of encryption it might not work. sorry for your loss!
Ok, it seems that this is a pretty common issue. I found a youtube video showing how to get around this. I watched some of it, the guys seems pretty competent. however, you might not be comfortable taking this thing apart or doing what he is doing. However, it is a relatively simple thing to fix for a competent repair person and I looked up new power assembly and they run around $25 on ebay. Here is the link for the video I found: https://www.youtube.com/watch?v=YMprUUBvlmo
There were a couple of other videos also that I didn't watch. However, if you just need this thing to work for a while and you intend to replace it in the near future and just need to get by for a short while, this should work. If you intend to keep this long term you might want to take it to a computer repair shop. Good luck. hope this helps.
