MacBookPro8,2 Didn't go to sleep on empty battery

Sometimes I live computer not connected to charger and usualy it goes to sleep.

But this time it drained the battery completely. Even the indicator on the side didn't blink. When I connected the charger hard drive clicked, parking the head and cd-rom made a sound and computer stayed off.

I turned it on. It booted normaly but after I logged in firewall start asking me for permissions and time was set back to 2000.

 

Any ideas what happened and/or troubleshoot?
