The Fn key is a key found usually on the keyboards of portable computers (laptops, netbooks etc) and sometimes on desktop type keyboards.
It is a key usually marked with a blue coloured "Fn" and is located somewhere on the bottom left row of keys.
The Fn key is used in combination with other keys that have (usually) blue letters or icons on them to activate the special functions (Fn) on these keys.
For example, on the laptop I'm writing this on; If I press F5 the computer would perform the action my software has normally assigned to F5. If however I press the Fn button and F5, the computers internal function for decreasing screen brightness is invoked.
Different computer makes have different assignment to their keyboard Fn so you can't generally say press Fn+F5 to decrease screen brightness, it might be assigned to something else, volume or sleep-mode or even nothing. The "blue" text or icon will give an indication of what it will do.
I'm not sure if your referring to sleep mode or not but I hope this helps There are several specialty key functions on the Lenovo Y410...here is a list....good Luck....please rate me ...The Fang
The following describes the features of each function key. Fn + Esc: Turn on/off the integrated camera. Fn + F1: Put your computer in sleep mode. Fn + F2: Turn off the LCD screen (any subsequent operation will turn the LCD screen back on). Fn + F3: Shift to other connected display devices. Fn + F4: Switch between wide screen and normal mode. Fn + F5: Enable/disable the built-in wireless networking feature. Fn + F6: Enable/disable the bluetooth features. Fn + F8: Enable/disable the touch pad. Fn + F9: Enable/pause Media Player playback. Fn + F10: Stop Media Player playback. Fn + F11: Skip to the previous track. Fn + F12: Skip to the next track. Fn + Insert/NmLk: Enable/disable the Numeric keypad. Fn + Delete/ScrLk: Enable/disable Scroll Lock. Fn + Pause/Break: Pause to view the system information during start-up. Fn + up/down arrow key: Increase/decrease display brightness. Fn + right/left arrow key: Increase/decrease computer volume.
You need to press hold the FN key and press the F4 function key once which toggles the display to the External Display source like the television connected along with the LCD of the Notebook.
If the FN and F4 key combination is pressed again, the display will dissappear from the LCD of the Notebook and remain only on the external source.
If the FN and F4 key combination is pressed third time, the display will be back on the LCD of the Notebook and will not remain on the External display source.
Here are these details in other way :
First time pressing FN + F4 ---> Display on LCD and External display
Second time pressing FN + F4 ---> Display not on LCD but on the External Display
Third time pressing FN + F4 ---> Display back on the LCD and not available on External Display (Normal position).
