Keyboard not working at all

Keep trying until the keyboard is ID'ed. Unplug, remove battery, plug in, reboot. Is there a reset button?

F keys don't work on reboot. Work on Power on boot.

When powering on the F2 key will get me to Bios Setup, F8 key will get me to Safe Mode, and F12 key will let me change Boot Device. Everything is normal when up on XP operating system. If I reboot, None of the mentioned function keys work. Instead I get a message of a "Keyboard Failure", but system will come up OK. But, on the reboot, I want to use one of those function keys.
I have a DELL 2400 Dimension running Windows Home XP. I am using a Logitech EX-110 (Combo keyboard & mouse)
This seems very similar to another write up on this site.
Any ideas? Don't tell me to toggle the keyboard. I tried it with no positive results

Some keyboards have an f-lock key that you enable quickly as the computer starts to boot. Only then will the F2 button work. If you are too slow to hit the f-lock key the computer will boot past the time window that allows you to enter the setup.

What do you mean not working? Is it that certain keys don't work, or the whole keyboard does not work?

Maybe your keyboard has been hijacked by a virus. Have you tried booting up in Safe Mode to see if it works?

Turn off the computer, then hit the power buttonto turn it back on and immediately start hitting the F8 key repeatedly untilyou see SAFE MODE. Take the Safe Mode option and let it boot up. SafeMode will look different to you, the screen will be darker and the iconsbigger, this is normal

need a little more info ie: what have you tried ?

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup

Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart if this fails to fix the problem

During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer

you could select the option start at last known configuration that worked this will tell what file has been corrupted or missing you might be able to work your way through problem if you are unable to find a solution

restart back into safe mode you might need to select your operating system to load into safe mode

click start control panel administration tools computer management in the left panel events + to expand then system you will see all errors in right panel right click select properties this will tell you what has occurred and the time it occurred

you might use the system restore to restore your system to an earlier time
click start all programs accessories system tools you should see your system restore option

hope this helps you

don

i would have told you to go into the bios but seen as you say that F2 key does not work on boot indicates that the keyboard has failed, to check this try another keyboard and see if you get the same result, or if the keyboard is USB try it in a different USB port

hope this helps

kind regards

I suspect someone at some time has spilt water on it and corrosion has set in you will need to have someone remove and clean it or fi a nnew one

Try using another application that has a use for the F2 key. I'm not totally convinced that your keyboard is good. It is possible for just one key to fail. Happens quite often.

Try This

Maybe you accidentally activated the F-Lock.
