• Workarounds:
  • Reboot the system and then do the one of followings:
    • Boot to Windows and do shutdown
    • Boot to EFI shell and do reset -s, this can also done via EFI shell scripting.
  • for automate booting to specified EFI entry, can be done by setting EFI boot next.
  • see section "Power state/operation workaround via EFI Shell" for information about EFI boot next, EFI scripting, and workaround automation.

You are required to setup the workaround by this below (this required disabling secure boot or sign the EFI file by yourself):

1. Getting compiled EFI shell source or prebuilt one. The x86_64 version is required. The EDK2 EFI shell is tested for this workaround. (Sample prebuilt: https://github.com/pbatard/UEFI-Shell ; you can grab prebuilt from non-DEBUG iso file located in latest release, the x86_64 EFI executable file of EFI Shell application is located inside <iso file>/efi/boot/bootx64.efi)
2. Copy x86_64 EFI executable file of EFI Shell application to your desired directory path in <EFI partition> (ex. /EFI/EFI_Shell/Shell.efi) (recommended in EFI partition of local disk, in case using Linux from external disk)
3. For setting-up EFI Shell auto-shutdown scripting, see step 4-5, or else skip these steps
4. Create file in desired directory (ex. /EFI/EFI_Shell/Scripts/shutdown.nsh)
5. Put this line in the file @reset -s
6. Read comment and set all the variable and execute the command to create new EFI entry

# Remark1: see https://uefi.org/sites/default/files/resources/UEFI_Shell_2_2.pdf for information
# Remark2: for manual shutdown or using EFI shell
#  - SHUTDOWNSCRIPT is not required
#  - remove "-u -@ ./cmdline.bin"
#  - the command from "cd ..." to "iconv ..." is not required
# Path to device file to disk contains selected EFI partition
DISKFILE=/dev/nvme0n1
# selected EFI partition, index start at 1
PARTNUM=1
# entry number do you want to create entry, recommened to be the equals to highest entry number visibled in the command `efibootmgr` added 1.
ENTRYNUM=0006
# Path to EFI Shell executable file relative to selected EFI partition, using backslash
EFIFILE='\EFI\EFI_Shell\Shell.efi'
# Path to auto-shutdown script relative to selected EFI partition, using backslash
SHUTDOWNSCRIPT='\EFI\EFI_Shell\Scripts\shutdown.nsh'
# Name of EFI entry
ENTRYNAME="Auto Shutdown workaround for Surface+Linux"
cd `mktemp -d`
echo -n "-nostartup -noconsoleout -noconsolein -nointerrupt -nomap -noversion $SHUTDOWNSCRIPT" > ./cmdline.text
iconv -f ascii -t ucs-2 ./cmdline.text > ./cmdline.bin
efibootmgr -v -b $ENTRYNUM -c -d $DISKFILE -l "$EFIFILE" -p $PARTNUM -L "$ENTRYNAME" -u -@ ./cmdline.bin
# for disabling the entry so we dont have to worry about entry sorting
efibootmgr -b $ENTRYNUM -A

After that you can boot to new EFI entry to perform shutdown. By using efibootmgr -n <Entry Number>, you can temporarily boot to selected entry after reboot. And you can apply this in init/PM scripts for automation too (For systemd, see here.
