Why can't I wake my JetDrive 850 up from Mode?

If you encounter this problem while the JetDrive 850 is running on battery power, please note that this issue will happen with all NVMe SSDs, including Apple's native NVMe SSD. Our current assumption is that the NVMe driver of the Mac OS is causing it. Please run Terminal on your Mac and enter "sudo pmset -a hibernatemode 3" to reset the mode to its default value: 3. You can also check if the hibernatemode has been successfully altered by entering the command "pmset -g".
