A:Answer Both of the other answers (strangely enough, even the one from Logitech) are inaccurate. There IS a Caplock indicator on the keyboard (an "A" symbol that lights up next to the on-off switch in the upper right of the keyboard), and there IS a NumLock indicator onscreen in or near the systems tray in the bottom-right corner of the screen.
Both indicators are ONLY operational when the device is actively connected through the USB receiver; You will not see the indicators (on the keyboard or onscreen) if the PC you are using is off, even if the keyboard itself is in the on position; The indicators only show when actively using the device (I assume this is a smart power saving measure).
