No hibernation after power loss

Hello,
my new MBP does not enter hibernation automatically after a total power loss and I keep losing my work and information. This was not the case with my old MBP. After checking, I found out my Sleep mode is the default one - number 3, which should prevent losses after power loss, however it does not. What should I do?
thank in you in advance

Try resetting the System Management Controller (SMC). See this LINK.
