The uses for the function (f1-f12) keys varies based on which program you have open at the time. Different programs use them for different things.

However, your computer also has some default uses for these keys when combined with pressing the fn (function) key.

fn + f1 locks computer

fn + f2 changes our power use profile

fn + f3 puts the computer to sleep

fn + f4 puts the computer into hibernation mode

fn + f5 changes the display/output mode

fn + f6 decreases the screen brightness

fn + f7 increases the screen brightness

fn + f8 enables/disables wireless connections

fn + f9 enables/disables the touch pad

fn + f10 turns the cursor overlay on/off

fn + f11 turns the numeric overlay on/off

fn + f12 turns scroll lock on/off

To enable the Wireless LAN Fn + F2

usually the wifi function key has the universal antenna symbol with radio waves emanating from it.

The manual says the other hotkeys are:

Fn + F2 - Wireless LAN
Fn + F3 - Standby
Fn + F4 - External display
Fn + F7 - Reduce brightness
Fn + F8 - Increase brightness
Fn + F9 - Play / pause media
Fn + F10 - Stop media
Fn + F11 - Media previous chapter

Fn + scroll - Scroll Lock

Hit your left Ctrl key twice

Hi,


The scroll lock key was meant to lock all scrolling techniques, though it is no longer used by almost any software. In the original design, scroll lock was intended to modify the behavior of the arrow keys. When the scroll lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor. In this usage, scroll lock is a modifier key like ALT and SHIFT (which modify the function of other keys) and, more specifically, a toggling Lock key like NUM lock or CAPS lock, which have a state that persists after the key is released.

you have engaged teh lock out feature, simply push in the control lock button for 3 secs to unlock not a problem! look close at the buttons,ones marked "contol lock" in small print under it, usually the heat dry button

Per the user manual, the brightness is toggled by holding the Fn Key and pressing F10. You post made no reference to the Fn Key being pressed. If using an external keyboard press scroll lock twice then F10.
