Afternoon......from a loose nut behind the keyboard.....how do you enable the F keys to work???? They don't respond in Excel, Word or in 3270 mode.... the keyboard is a Microsoft wireless keyboard 3000... Regards, Lou

If your space bar isn't responding when you press it, or if it responds sluggishly, it's possible that you have inadvertently enabled the "Sticky Keys" or "Filter Keys" accessibility option in Windows.

When these options are enabled, your keyboard response time will be dramatically slowed and may require more than one tap to register a keystroke.

Fortunately, it's easy to disable these functions and return your keyboard to normal working order.

Click "Start" and select "All Programs."

Click "Accessories" and select "Ease of Access."

Click "Ease of Access Center."

Click "Make Keyboard Easier to Use."

Click "Set Up Sticky Keys." Deselect the checkbox that says "Turn on Sticky Keys When Shift is Pressed Five Times." Make sure the box that says "Turn on Sticky Keys" is not checked. Click "OK" to save your changes.

Click "Set Up Filter Keys." Uncheck the box that says "Turn on Filter Keys."

Click on the checkbox next to "Turn On Filter Keys When Right Shift Is Pressed For 8 Seconds" to deselect it. Click "OK" to save your changes.

Click "OK" again to save all of the keyboard accessibility changes you have made.

Hope this helps

Although having a laptop is certainly convenient, the all-in-one peripheral scheme (mouse, keyboard and speakers) can make individual repairs difficult, and a non-working keyboard can ruin the value of the entire package. However, there are some practical steps you can take to fix a laptop keyboard.

1.Diagnose the problem. When you press a key on your laptop keyboard, does it get stuck? Does the computer respond to your inputs? In almost all of these cases, the solution will lie in opening up your notebook's keyboard. However, to prevent extra work, press every key (do this in a word-processing program) and see which keys are affected. If every single key on a keyboard does not respond, you might have a software issue, which may require specialized help.
2.Clean the area around the keys that are not working. A damp lint-free cloth should be used to clean the surface of the affected keys. If you have stuck keys, use a Q-tip to clean under them, but take care not to pry the keys up, as this could result in further damage to your keyboard.
3.Remove the keys that are not working. Do this by grabbing some fingernail clippers and pulling out the hook-like fingernail cleaner extension. Use the small hook to gently pull the key up , which will expose a collapsible plastic hinge (commonly known as a key retainer) as well as a small rubber circular piece. Gently lift both of these pieces out of the keyboard.
4.Wipe the keyboard sensors clean with a dry cloth. The sensors are the little silver foil-like strips you see after your key components have been removed. Be very careful wiping these down--if they are damaged, they are very expensive to replace. Just gently dab it with a dry lint-free cloth to remove any dust/crumbs/particles that are interfering with your keyboard's functionality. Do not moisten the cloth with water or cleaning solution, as this heightens the risk for damage.
5.Reassemble and replace the keys. Simply fit the key retainer as well the little rubber piece together in the way you found them and then firmly press the key cap back in place.
6.Test your keyboard. Open a word-processing program and then press the replaced keys. If they still don't work, try restarting your computer, or activating a system restore point (to ensure that the problem is not software-related). If the keyboard is still not working, then you may want to think about taking the computer to a repair shop or replacing it altogether. (Keyboard repairs are very expensive.)

Thanks.

You will need the correct software installed to do this. XP does not inherently have this so those functions will not be activated. Install this software, reboot and try again. Make sure if there is function or special key to activate a dual purpose key (two functions on one key -check key face for two functions). Sometime you may inadvertently toggle this off and THINK it fdoes not work. Maybe try this first to avoid installing stuff for no reason.

Good luck!

probably your son might lock the keyboard what you have to do is that on the keyboard you will see where they wrote Fn key beside the ctrl key hold or press the key, then on top of the functional key i.e F1 to F12 among those keys you will see where they draw or shown something like key or padlock press the key in other to open your keyboard.

In case it doesn't work try the second option.

well, what i can say is that try to loose the laptop you will see where they wrote kb at the back of the laptop then loose those screw after loosing it, then bring out the keyboard with the flex then dust it out.
if it those not work again change the keyboard.

Here is the best description for this key I have seen. I remember using this key on an old IBM 3270 system.

Does the slow movement of cursor and keyboard seen only on excel? Given that your excel is not corrupted, it just could be the file size of the worksheet you are working is too big. But if the slowness is present even on small excel file, you may consider re-installing your excel.

But if the slowness is present even on other application, then the problem could be on your pc itself.

does it work in other applications? If so check under the 'help' in excel to locate the shortcut to re-enable

please check behind the laptop and inditify screw nuts that have a keyboard icon fig 1. remove the nuts and you will be able to replace the keyboard. they don't usually exceed 3-4 nuts. take note

fig 1.

Try attaching an external keyboard to a USB port on the computer. If it works.

The keyboard cable is probably loose.

It is odd that it will type before you log in, but not after.

If you have access to a USB desktop keyboard try using that to see if it works after windows has been logged in.

I'd also check the Device Manager. You can get their by clicking on the start button, then click run. After the box pops up type "devmgmt.msc" into it. This will pop up a box that shows you all the devices in your computer. When this is open find the keyboard section and click on the ' + ' . After the keyboard section is expanded look to see if anything under their has a red ' x ' or a yellow exclamation point through it. If it has one of these symbols, double click on it and try to enable the device. Let me know if this doesn't do anything, there may be 1 or 2 more things to try.
