After the computer restarted, all the text in the notebook disappeared, - this is the way it should be, or is it a mistake !?
It happens to me how to stop and fix it forever.

what do you mean by “computer restart”? Accidentally restarted?
Do you saw this FAQ? Might it solve your issue?

Or maybe see this FAQ which will not solve your issue and likely will make you sad…
