nvrampower-managementsleep-wake
okay so my MBP Mid 2010 was took a little tumble (it was in a felt sleeve which was inside a backpack) today and since has been acting weird.
when i open the lid, the login screen does not come back on automatically, i have push a key, move a finger or two on trackpad and only then does the display get powered
what to do? I am on OSX 10.8.5 and non SSD, 4GB Ram.
Plz help!
The SMC controls things like sleep, fans, etc. Reset the SMC by following the instructions here: http://support.apple.com/kb/HT3964
EDIT: In case that link dies, you restart the MacBook Pro while holding down these keys on the left side of the keyboard: Ctrl + Option + Shift
In addition to the destroyfvkeyonstandby option, you also need to specify that pmset is setting hibernatemode 25 for the power management options.
sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25
Setting both options ensures that the Mac in question will hibernate (where the contents of the RAM are written to disk) and also have the FileVault 2 key automatically removed from the saved RAM.
When the laptop is awakened from hibernation, you should see your account icon and a password blank at the FileVault 2 login screen, which would indicate that it had been asleep.
When this setting is set, you may run into some Power Nap-related issues. I have a post on that available from here:

Check that
pmset -g hibernatemodecommand in Terminal gives you 3 or 0 and not any other value. If it gives you something else, executepmset hibernatemode 3(this is the correct default).Sometimes these settings go wrong for unknown reason.
