Does they function normally ? you should have mentioned it. welll still i take it to be yes, they funcion normally good. but when combined they do not. I think its a virus problem . go for a thorough scan using a good updated antivirus. Still if the roblem persists, go for a fresh format. if still the problem persists i think its the problem with the keyboard itself. replace it.

Function keys not working on hp probook 4440


Identifying the hot keys
A hot key is a combination of the fn key and either the esc key or one of the function keys.
To use a hot key:
Briefly press the fn key, and then briefly press the second key of the hot key combination.
Hot key combination Description
fn+esc Displays information about system hardware components and the system BIOS version number.
fn+f1 Initiates Sleep, which saves your information in system memory. The display and other system
components turn off and power is conserved.
To exit Sleep, briefly press the power button.
CAUTION: To reduce the risk of information loss, save your work before initiating Sleep.
fn+f2 Decreases the screen brightness level.
fn+f3 Increases the screen brightness level.
fn+f4 Switches the screen image among display devices connected to the system. For example, if a
monitor is connected to the computer, fn+f4 alternates the screen image from computer display to
monitor display to simultaneous display on both the computer and the monitor.
Most external monitors receive video information from the computer using the external VGA video
standard. The fn+f4 hot key can also alternate images among other devices that are receiving video
information from the computer.
fn+f5 Initiates the QuickLock security feature. QuickLock protects your information by displaying the
operating system Log On window. While the Log On window is displayed, the computer cannot be
accessed until a Windows user password or a Windows administrator password is entered.
NOTE: Before you can use QuickLock, you must set a Windows user password or a Windows
administrator password. For instructions, see Help and Support. To access Help and support, from
the Start screen, type help, and then select Help and Support.
fn+f6 Displays charge information for all installed batteries. The display indicates which batteries are
charging and reports the amount of charge remaining in each battery.
fn+f7 Mutes or restores speaker sound.
fn+f8 Decreases speaker volume.
fn+f9 Increases speaker volume.
fn+f10 Plays the previous track of an audio CD or the previous section of a DVD or a BD.
32 Chapter 4 Pointing devices and keyboardHot key combination Description
fn+f11 Plays, pauses, or resumes an audio CD, a DVD, or a BD.
fn+f12 Plays the next track of an audio CD or the next section of a DVD or a BD.

Wont connect to external display windows 7


You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

What is the fn key


I suspect this is a message you're seeing on a notebook, computer or other device that has a keyboard. The "Fn" key is the "Function" key. When the "Fn" key pressed at the same time another key is pressed - in this case the F4 key, a different result will occur when compared to pressing the F4 alone. This works the same way as when you use the SHIFT key and a letter key - instead of a lower case letter, you get an upper case letter.

Typically, the keys on the keyboard are labeled in a light color. Keys that have a second purpose or function, will have a second label printed in a different color / slight smaller text or both. This label may be text or an icon or graphic. In order to invoke the second function of the F4 key, you will need to inspect the keyboard for the key that has is labeled with "Fn" text on it. Here's what a typical "Fn" key looks like:

The Fn key is in the lower left corner of this keyboard.

I hope this answered your quiestion and good luck!

My keyboard won't light up on an ASIA G73J. I have tried the function keys and they won't work.


Did you hold down the [fn] key, in combination with the function keys? If not, you have to hold down the [fn] key in combination with pressing the function key's that are associated with the keyboard back-lighting (usually [F3] or [F4] on an ASUS G-series).

I need an explanation as to the secondary function of the keys on my NB305. Mainly the top row of 'F' keys, but the remainder of the keyboard as well. What do all these little symbols on the keys mean?


F1 through F12 are called function keys because they execute programmed functions when pressed. Used in combination with the Fn key, keys marked with icons execute specific functions on the computer. The function executed by individual keys depends on the software you are using.





1. Sound Mute: Pressing Fn + ESC in a windows environment turns sound on or off. Press Fn + Enter to simulate Enter or the enhanced keyboard's numeric keypad. 2. Instant security: Press Fn + F1 to blank the screen to prevent others from accessing your data. To restore the screen and original setting, press any key or press the Touch Pad. 3. Power save mode: Pressing Fn + F2 changes the power save mode. 4. Standby: When you press Fn + F3, the computer enters Standby. 5. Hibernation: When you press Fn + F4, the computer enters Hibernation. 6. Display selection: Press Fn + F5 to change the active display device. Hold down Fn and press F5 again to change the device. 7. Internal LCD screen Brightness: Pressing Fn + F6 decreases the display brightness in decrements. 8. Internal LCD screen Brightness: Pressing Fn + F7 increases the display brightness in increments. 9. Wireless setting: If your computer has both Bluetooth and Wireless LAN functions, you can press Fn + F8 to select which type of wireless communication you want to use. 10. Touch Pad: Pressing Fn + F9 in a windows environment enables or disables the Touch Pad function. 11. Press Fn + F10 or Fn + F11 to access the integrated keypad. When activated, the keys with gray markings on the bottom edge become numeric keypad keys (Fn + F11) or cursor control keys (Fn + F10). The power on default for both settings is off. Press Fn + F12 (ScrLock) to lock the cursor on a specific line. The power on default is off. 12. TOSHIBA Zooming Utility (reduce): To reduce the icon size on the desktop or the application window, press the 1 key while holding down the Fn key. (13. TOSHIBA Zooming Utility (enlarge): To enlarge the icon size on the desktop or the application window, press the 2 key while holding down the Fn key.

Which function key allows to switch to tv


Hi there,
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).
Below are the details of what the Function keys in your DV1000 Notebook work :
fn + f1 Opens Help and Support Center fn + f2 Opens print options window fn + f3 Opens default Internet browser fn + f4 Switches the image among displays fn + f5 Initiates Standby fn + f6 Initiates QuickLock fn + f7 Decreases screen brightness fn + f8 Increases screen brightness fn + f9 Plays, pauses, or resumes an audio CD or DVD fn + f10 Stops an audio CD or DVD fn + f11 Plays the previous track or chapter on an audio CD or DVD fn + f12 Plays the next track or chapter on an audio CD or DVD fn + esc Displays system information.* (*To clear the system information display, press esc.)
Hope this helps...
