A days worth of paperwork lost on 2 day old laptop that wont turn on

Do you have a desktop at all? If you do, you're best bet would be to remove the HDD and plug it up to that and retrieve your files.

Otherwise, this article might help:

If you need help in removing the hard drive, look up a service manual for your laptop or ask a tech savy friend to help you out.

I don't have much experience with the what will/will not void your warranty but this should at least get your documents.
