Question about Mitsumi (KFK-EA4XT/PS2) Keyboard

1 Answer

"Reprogrammed" keyboard I teach a keyboarding class to 7th and 8th graders. I can usually fix their problems, until today. One of my students "reprogrammed?" the keyboard. It will only type as if caps lock was on. Even the number keys act as if the caps lock is on. Does anyone know how to fix this?

Use of crescent key above escape key in model HP 5187-7583 Silver Multimedia Keyboard With Media Player

The crescent key is for the computer to go night night!
Look under power settings in control panel this could be a key that can be reprogrammed. Usually out of the box it will but the computer into sleep mode.

For some key boarda the "Fn" key and crescent both need to be depressed.

Shaking the mouse or hitting space bar will wake up the computer.

Hope this helps?

I teach in an elementary school computer lab. I have a lab of 37 networked Dell Optiplex computers. I am having a problem with our keyboards randomly not working. Any given student will be working in our...

I have had some similar problems with computers and using more devices than was effectively able to sustain for any extended period of time.
Computers use IRQ's or Interrupts (Like a stop light at an intersection) to allow hardware devices to work on the same IRQ. If randomly two devices or more try to work simultaneously (enter the intersection) the computer will hang. Computers only have 15 IRQ's and half of them are used for overhead.
If you go to the control panel/system -> Hardware Tab/Device manager you will be able to view all the installed hardware. You can expand the individual items and check for conflicts. Usually a yellow triangle like a caution sign on the roadway. This mostly applies to the non-USB hardware.
If you expand the USB Controllers + to a minus you will see the possible conflicts on the USP comports.
Possible solution for your IT manager:
Experiment with 2 or 3 computers and change the various boards to different slots on the mother board to correct IRQ conflicts. (Better managed stop and go lights)
For USB conflicts sometimes updating drivers can resolve that issue. Removing and reinstalling keyboards, mice, USB hubs may help reassigning these device to more compatible USB numbers.
You may be able to work out some routines that cause conflicts every time and try to avoid those combinations. i.e. opening MS Word, Browsing, and running calculator at the same time consistently causes computers to hang??? You could then plan around that.
This appears to be more of problem of random conflicts on individual programs.
Hope this helps,

You need to reset

There is a reset button on the underside of the keyboard, one on the receiver, one on the mouse if you have one.

I'm not familiar with you make of keyboard but the sequence is prettyy easy to work out.

Start by numbering each device eg Keyboard=1 Receiver=2 mouse=3.

There are only 6 combinations so go thriugh them one by one until you have everything connected and make a note of the sequence for future reference.

You may have activated a shortcut key on your keyboard such as the Fn (function) key. It looks like this

Fn and usually situated on the bottom left hand side of your keyboard near the left hand cntrl button.

Some function keys when pressed once remain on. Once they are on they can cause different symbols to appear in place of the normal keyboard ones. If you press your Fn key again and then try typing on the keyboard once again it may help fix your problem.

I hope this helps
