"FastBoot" aka fast startup happens when shutting down if not > disabled. And it's hibernate without hibernating apps so fairly useless. Actually Fast Starup is a full hibernate (all memory copied into the hyberfil.sys file). The computer then goes into sleep mode. When brought out of sleep, the computer resumes from sleep. If, however, the computer ever lost power during sleep, the computer resumes using the hibernate file. Because a memory image is reinstated or resumed from a Fast Startup mode, there is no re-initialization of hardware. This is the same as a Windows restart which is a warm boot. Fast Startup causes problems with hardware, because the hardware is not sent a reset signal to ensure it is initialized to a known initial state. A restart using Fast Startup will not fix hardware problems caused by hardware getting into a state the devs did not plan upon in their driver, or their driver simply cannot perform an initialize the way the hardware was designed. Even using hibernate mode without Fast Startup can prevent troubleshooting problems when booting the OS, because the memory image gets restored, and you don't want that when troubleshooting. You don't want to get back to the state that had problems, but load a new memory image. Fast Startup can be enabled or disabled by itself. If hibernate mode is disabled, so is Fast Startup. If you have an SSD for the OS partitions, Fast Startup provides little assist in shortening cold boot (which only happens if the computer lost power during sleep). Fast Startup can make it impossible to get at the boot menu, because Fast Startup begins so quickly that keyboard input is ignored, and you cannot get the boot menu to, say, elect to boot from a CD or USB drive instead of the BIOS configured primary boot device. Fast Startup was intended for use with old slow computer, especially those still using HDDs.
