Python pywin32 - VK_SLEEP press not working

I found this solution for pressing virtual keys: https://stackoverflow.com/a/10441322/3448364
But, problem is that VK_SLEEP not working for me. I tried with all other VK_ keys (like VK_VOLUME_UP, VK_MEDIA_NEXT_TRACK...) and it works, only VK_SLEEP not working.
This is my code:
VK_SLEEP = 0x5F
hwcode = win32api.MapVirtualKey(VK_SLEEP, 0)
win32api.keybd_event(VK_SLEEP, hwcode)
When I execute that code, nothig happens. When I change virtual key to ie. VK_VOLUME_UP: works like a charm! So, code is OK, but for some reason script won't put PC in sleep with VK_SLEEP.
This is source for VK_ codes that I use: https://docs.microsoft.com/en-us/windows/desktop/inputdev/virtual-key-codes
Just to be clear: my keyboard doesn't have dedicated Sleep button. But, doesn't have "volume up" too, and 0xAF (vlume_up) works. So, I don't think problem is keyboard (it's CM MK750).

Simulating VK_SLEEP will not have any effect, probably for security reasons.
Changing the systems's power state requires SE_SHUTDOWN_NAME privileges. If privileges is changed successfully, you can use SetSuspendState to put the computer to sleep.
import win32api
import win32security
import ctypes
def sleep_mode():
access = (win32security.TOKEN_ADJUST_PRIVILEGES | win32security.TOKEN_QUERY)
htoken = win32security.OpenProcessToken(win32api.GetCurrentProcess(), access)
if htoken:
priv_id = win32security.LookupPrivilegeValue(None, win32security.SE_SHUTDOWN_NAME)
win32security.AdjustTokenPrivileges(htoken, 0,
[(priv_id, win32security.SE_PRIVILEGE_ENABLED)])
ctypes.windll.powrprof.SetSuspendState(False, True, True)
win32api.CloseHandle(htoken)
sleep_mode()
Side note,
keybd_event pushes the key down. Make sure the key is pushed back up. Example:
import win32api
import win32con
win32api.keybd_event(win32con.VK_VOLUME_UP, 0)
win32api.keybd_event(win32con.VK_VOLUME_UP, 0, win32con.KEYEVENTF_KEYUP)

Edit: only problem is that PC wake up immediately after I put it in sleep. There is no problem if I put PC in sleep in classic way (Start menu), only with this script.

That's odd. The second parameter inSetSuspendStateshould disable wake timers as stated in MS documentation. What is your OS?
