My keyboard does not display the letters I am keying

You probably have set keyboard repeat delay to "long"

use the shift key

I understand that a letter is not displayed on a screen while you press the key. Since this difficulty is happening for a single letter, I think the issue might be hardware related. To confirm that it is a hardware issue, you can try an external keyboard.
If the letter is not displayed even while using the external keyboard, you might need to reinstall the keyboard driver or restore the system or reinstall the operating system.

what os? XP > start > control panel > regional & language settings > change all tabs to match your region and language

is your number lock on? if it is turn it off and everything should be fine...

when u are cleaning ur keyboard u should always clean it with wall painting brush.. if the keys are not working u will hav to change d keyboard.. bcuz keyboards are non-repairable these days.

1. Open the on screen keyboard by going to "control panel" then "Ease of Access Center" then click on "onscreen keyboard".

2. click and hold down the "Fn" key on the physical keyboard and then hit F11 on the onscreen Keyboard.

3. All Fixed. Spread the word.

It looks like you answered your own question - you really can't fix a laptop keyboard, but you can replace them. (or you can use an external keyboard)

Now is your problem:?
Letters qwert, asdfg, zxcvbn work OK but uiop displays as 456/ jkl displays as 123 and m displays as 0. Other keys also do not display correctly. Or holding the function key down at the same time as the problem keys ?

Then the solution is:
The problem was caused by accidentally pressing the num lock key. Once pressed, it remains locked even after a reboot. Pressing again returns the keyboard to normal.

Keyboard 99 is Laten supplemental. Try holding down the code key and pressing the x key it should reset the keyboard.

Typeing with the Logit. keyboard shows no letters on my Gateway screen. Changed batteries. Arrow works appropriately, but no letters seenon the Gateway scree.
