I probably have seen the Linux version of power settings at some point in my past, but I've always left the defaults in place. Given that Linux is so "configurable" I am certain these power settings are in different places in different distributions. That may explain why I can't find them. The equivilant Windows settings are in the obvious place (Control Panel Power Settings) and I have no problem making the laptop and the desktop perform to my requirements.
Windows has had problems with hibernation, and to a lesser extent sleep, since around the era of Vista when laptops became popular. There have been patches, hot fixes, updates, and service packs issued to address the problem, but to this day my Windows 7 is only 50% likely to come out of hibernation properly. When hibernation takes place the desktop environment and all the associated processes are saved to the hard disk. It's a bit like making a snapshot image of the existing state of affairs. Sleep, on the other hand, only saves the kernel state. Thus it's a lot quicker to go into the sleep mode, but the price for that is that the computer never really shuts off. It does shut off completely in hibernation.
Microsoft has taken great strides to use the sleep mode to its advantage. It optimized it's OS code so that shutting down and booting up is simply a matter of saving the kernel state or retrieving it. The end results of their efforts is that my preview version of Windows now shuts down instantly and boots in under two seconds. You would think this is wonderful, but it's not.
Back on the old Toshiba laptop I had an MBR formatted hard drive. That's the system I could multi-boot anything from HDD or external memory. It's the system I've been lamenting ever since I bought the MSI laptop which is no longer MBR. I had a unique problem with that Toshiba. Windows 10 was the default system I worked with constantly and I would shut it down every day after each session. On the next boot, if I decided I wanted to boot into one of the Linux OS's instead of Windows I'd have to press F12 to get the BIOS boot device selection menu. I could pick the HDD or USB or CD or whatever from that menu and boot right up. Well, that was not happening at one point., I was getting an S4 boot message instead of the menu. From there it went right into Windows. This S4 error was due to the fact that when I shut down Windows it went into the "sleep" mode which kept BIOS alive. So BIOS just continued from where it was when Windows went to sleep and did not give me a choice of boot devices.
I did a lot of head scratching and tech forum searching, but could not find a similar problem. Eventually it dawned on me to go to the Windows Insider Preview Feedback site (duh) to see if they had an answer. They did. In fact a genuine honest to goodness Microsoft engineer explained to me that there are two ways to "shut down" Windows 10. The way I was using was very common and obvious, but it didn't really shut down cold. It went to sleep instead. To shut down cold I had to use an optional menu that I've been ignoring up to that point. That optional shut down turns the OS off cold and the next boot would give me the device selection menu if I wanted it. That's one of those How-To instructions that are not written anywhere. You are just supposed to know intuitively what to do.
So, that's how I learned about sleep, hibernate, and shut down power settings. Now, if you could, point me to the exact place in Linux that I can adjust such settings. I'll be eternally grateful to you until the end of time.
