sp3 troubleshoot

I’m afraid that I have lost any info or files that are on my SP3 that wasn’t saved to OneDrive because I can’t get my SP3 to turn on. It fell and I have a small crack on the bottom left corner of the screen. Is there any way to get the info backed up somewhere somehow? Thanks

My pen keeps shutting down constantly for a couple seconds to a minute, I replaced the pen, the battery, I remove and reinstall the battery when it shuts down and still nothing, reinstalled the drivers and still fails. Anybody know how to fix the issue?
