One key letter 'c' does not work


Have you tried cleaning your keyboard? Usually when that happens there's some kind of grossness stuck in it.

Lenove ku-0989 fn key


  1. Numerous folks indicate that Windows doesn't register the Fn key as a keypress but using a tool that gives the ASCII value of a keypress I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table.

  2. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy.

My computer is dell inspiron,the letter 'd' in my keyboard is not working,and when i'm turning on my computer for the first time,always letter 'd' is being typed by itself


If this is a wired keyboard (USB or PS2) then turn off the computer. Unplug the keyboard, and bang it against your palm to work some of the debris out of the keyboard. Now check the d key and make sure it bounces back when pressed.

You might also take a small screw driver and pry the d key off the key board and see if there is anything sticky on it. If so try cleaning with alcohol.

Last ditch effort before replacing the keyboard completely: Run the key board under running water to rinse it. MAKE SURE YOU LET IT DRY FOR A COUPLE OF DAYS (KEYS DOWN) BEFORE PLUGGING BACK IN. I have had this method work more than once. If it works its great if not, then non of the key board will work.

When using the keyboard, every time i click the letter b on it, it causes Window's Media Player to open. But the Ctrl key on the left side doesn't allow me to use short cuts in my programs anymore...


Sounds like your cntrl key might be getting stuck..

A couple of things you can do. you can take the key off, and clean round the key. And Believe it or not, you CAN put the keyboard in your dishwasher, but you have to shake out the left over water and let it sit for about 4 days.

Also try a good dust cleaner to see if that will help.

Laptop keyboard- when using the letter t opens a new tab.. sometimes using the key r will close a tab. It happens when surfing or composing emails.


It sounds like the Ctrl key is stuck. Tap both of them a couple of times to get unstuck. This should work. Best of luck to you :)

Sometimes when I type on the keyboard it skips keys that I am striking. I have to strike the key harder to make it register. This only happens sometimes, not all the time.


This is cause by foreign material between the key contacts. Sometimes exercising the key vigorously will fix it, mostimes the keyboard has to be removd and contacts cleaned or keyboard replaced.

Gateway model md7818u keys dont register the letter when struck- happens frequently, especially on the qwerty line


Replace the keyboard -- it's not worth paying a technician to diagnose the problem, and there's little that (s)he can do to repair it.

Keys have to be struck over and over to work


Could just be your keyboard settings in control panel click keyboards maybe your settings are set to slow.
You may need to update your driver.
If this does not work your keyboard may just need to be cleaned
If this does not work and you have a cd for the keyboard I would run it again.
Hope these suggestions help
