My Function Keys stopped working (audio, too)

Had some remote computer service done by the GS and the next day neither my audio nor my function keys worked. One of the things that was done was to turn off a bunch of start up items so that my sys would load faster. Do you think something was turned off that I need for my function keys and if so, which one?

I saw this problem while scanning the net looking to solve the same problem on my partner's laptop. Her sound just quit working, worked yesterday, did not work this am after being turned off overnight.

The solution that worked for us was to try system restore back to when the sound worked, which was yesterday - that solved the problem.

I know this is waaay to far back for you to restore to, but maybe it will help others.

Best Regards
Patricia

Go to start > Run
Type 'services.msc' without the quotation marks and press OK
In the window that opens, all services that are present are listed.
For each service is shown, if it is started and how it is started.
Look for 'Remote Procedure Call (RPC)' and check if it is started and startup type is automatic. Do the same for 'Windows Audio' and 'Plug and Play'.
Could be there is also a separate service for your sound card, but unless you give some more information about your laptop and sound card, i don't know if it is.

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.

My Samsung laptop's (np-r430-jb01ae) function keys are not working. how could i solve it?


Step 1:
Function keys are special keys used for assigning program shortcuts and specialty tasks to the keyboard. They are located at the top of most keyboards and labeled "F1" through "F12." Some keyboards may only feature 10 function keys, while others may have as many as 18. These keys often go unutilized by the average computer user, but they may have very important tasks for some users, which can lead to problems when the keys do not respond. Fixing nonresponsive or malfunctioning function keys is quite simple, and should only take a few minutes.

Connect your keyboard to your computer, and power it up. Open a program that uses the function keys such as Microsoft Word or Microsoft Excel. Check your keyboard for an "F-Lock" or "Function Lock" key. This key is used to toggle function-key support; when it is toggled on, the function keys will not work. Press the "F-Lock" key and then try using a function key in the selected program. "F1" is a good key to test, because it is set to open a "Help" document in all Microsoft software. If the key does not work, press the "F-Lock" key a second time, and test the keys again. If the keys still do not work and you are running the Windows 7 operating system, you may need to install a "hotfix" from Microsoft to fix the key functionality. Navigate to the link entitled "Microsoft Support: Some Function Keys do not Work Correctly." (See Below.) Some function keys or keyboard shortcuts do not work correctly on a computer that is running Windows 7 http://support.microsoft.com/kb/975741 Resolve unexpected Function (F1 - F12) or other special key behavior on a Microsoft keyboard http://support.microsoft.com/kb/894513 Click on "View and request hotfix downloads" located beneath the title of the article to access the Microsoft Hotfix database. Agree to the terms and conditions, then download the hotfix. When the download is finished, run the downloaded file and follow the on-screen instructions. You may need to restart your computer after the installation is complete. Your function keys should now work properly.

How i can enble function key


HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

How to unmute the machine - no sound at all


Usually the sound on the OS is directly tied into the physical sound controls on the laptop.
Most new laptops now-a-days have keys called FUNCTION keys which are usually represented by light blue icons on other keys.

Look for the FUNCTION keys associated with the sound (think speakers, +/- etc)
You should find some keys somewhere (usually number keys) that have these blue icons,
you should also find 1 or 2 FN keys (usually near the left CTRL/ALT keys)

Hold down the FN key and press the MUTE key or the + key several times.

Still nothing? Try changing the volume in windows (double click the speaker icon in the system tray, no speaker icon? is it hidden? expand the system tray by press the little area inside of it.)

STILL nothing? Make sure your sound device is working properly.
Easiest way to check this is (VISTA/7) click START and type in Device Manager, (XP right-click MY COMPUTER, then PROPERTIES, then the HARDWARE tab then DEVICE MANAGER button)

Sound controllers has it's own section, if your sound card has an icon next to it try reinstalling the device drivers and rebooting.

STTTIIILLLL nothing? Speakers may be broke or even a BIOS setting (complicated)

What are the keys at the top of my toshiba beginning with F


HI there,
The function keys (F1 through F12) are exactly that. Function Keys.
F1 generally opens a Help dialogue
F8 opens your windows startup manager when booting windows
F10/F11/F12 Can be used in some BIOS managers
These keys are dependant on what operating system you are using which will define what they do. Some OS's allow you to program these keys to open different things.
