Lenovo N200 - hotkey for screen OFF

[Kika]

Need some help for turning off my lenovo screen, as there is no hotkey combination for this.
Under Lenovo Care is an option to turn the screen off, but that is little bit annoying all the time first press Care button, then click there with mouse, specially when you at hurry and not sitting behind the table and want to do this fast.
Under "Power off display" settings I found: "C:\PROGRA~1\Lenovo\LENOVO~1\LPMISC.dll,LP_Misc_MonitorOff"
How to make a batch file for it to put to quick launch so I can assign hotkey to run it?
Hope someone can help me with this

edit: the full folder for that .dll file is: C:\Program Files\Lenovo\LenovoCareSP

I solved another way. Downloaded "nircmd" http://www.nirsoft.net/utils/nircmd.html did put to system32 directory and made batch file with following lines:

nircmd.exe cmdwait 2000 monitor off

I added 2 seconds, because without timer my mouse turned monitor right back on.
