Hibernation in MBP2014

Hello!

I have MBP2014 with two OS: Mac OS and Win7 via BootCamp. Usually I work in MacOs, but sometimes I need to make some things in Window, and I want to hibernate MacOS (not close opened programs), reboot and boot up to Win. I read man about pmset and set up hibernation mode to 25 (pmset -a hibernation 25), but when I close lid or select sleep via main menu - notebook goes to ordinary sleep.

Also I try 2 utilities: Smartsleep and Hibernate. There are not working properly: both utilities put notebook only to "hot" sleep.

How can I make force hibernate this laptop for my task?

P.S. I don't check, what happened, when my battery emptied in sleep - I use it every day near sockets))

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

You can't if you are using Boot Camp. Once you boot Windows there is no more OS X running.

If you wish to be able to readily switch between Windows and OS X, then get rid of Boot Camp and using a virtual machine such as Parallels for Mac, VM Fusion, or Virtual Box.

Windows on Intel Macs

There are presently several alternatives for running Windows on Intel Macs.

Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.

Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox.Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.

You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

I understand what is BootCamp OS and what differences there are between BootCamp and VM. I use VM too.

My question about hibernation!))) I want to hibernate my notebook (not shutdown) and reboot it. How can I do it? pmset not working.

You can't. Hibernate via pmset is what happens when you close the lid on a laptop. When you switch from OS X to Windows using Boot Camp then OS X is no longer running. You cannot hibernate what isn't running. What you are asking to do is not possible.

OK. I ready to close lid and open it later for reboot))

As I understand, Hibernate saves memory to disk, modify boot manager for next restore and disconnect power from all components. When I open lid, notebook must show first screen (with apple) and start boot manager, if I push alt-key in this moment, I must show a boot menu with boot selection, but notebook start very fast and open Mac Os. Speed of booting, tell me, that it is restore from sleep (data been saved in memory). I right?

No, you are not correct. When you open the lid after hibernation you are returned to the screen that was present when you closed the lid. There is no return to a boot screen.
