My book is dead, do not turn on

My book is dead, do not turn on. I thought broken adapter. I bought a new one, but it is not working. What should I do? what is the reason? Can I revive my book? Or at least get my files from it?

Hello,

If you have need to recover the data from your drive I recommend you contact a data recovery company.

Than you very much! I’ll try do this.
