I am pressing printscr button single, printscr+fn key(it is enabling or disableing Bluetooth) and ctrl+printscr(it is taking the screenshot of the screen)
So please solve my problem as soon as possible.

There might be a small switch somewhere on the case or one of the Function keys may have the wi-fi icon on it.
