    This is the driver that I previously installed, my fn+f9 and f10 keys still don't work. I have 33 of these laptops to deploy and noticed the hotkeys not working after imaging 10 of them. Thanks for your assistance.

  • Tom Insane Dec 28, 2011

    first I would like to thank Martin Murray for his assistance!
    I have XP Pro SP2 and do not want to update to SP3.
    the driver sp51993.exe works, but only for SP3.
    is there any working hotkey driver which works with XP SP2?
    HP does not offer any in the driver list...
    thanks a lot!
    Tom

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.

Probook 6470b is there any kind of illumination? So you can work in darkness. Not the illuminated keyboard... I know I don't have that option.


If it has a Fn button on the bottom left of the keyboard next to the Ctrl key, press the Fn button and hold down, then press the arrow keys left or right while holding down the Fn key.

Where's the button to enable wireless on the HP ProBook 6450b


You probably don't have a switch. You need to use the wireless application you will find in the control panel or the Fn key-special function key combo that is made for the wireless.
Hold down the FN key and then look up at the special function keys and see which one has a picture of an antenna. That combo will turn the wireless on or off.

While pressing the fn+f4 or any other f-key, there is no response, so I cannot swith to external monitor or projrctor, nor change the brigtness of display. I have Probook 6550b with Windows 7 downgraded...


FN keys are not controlled by drivers. These are hardware switches built in to the laptop. You can try doing a BIOS update on the system from HP.

How do I turn up the brightness on a HP Probook 6550b?


PLEASE RATE ME!
go to the search icon under start. search brightness. it will tell you step by step what to do.
Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.
