How to lock your keyboard and mouse from being pressed?

You probably have ever had this kind of experience. You're away from computer for a while and when you're back, you find that your computer keyboard and mouse have been pressed (whether by a cat or your kids at home). Of course, you'll find it very irritating. Then what should you do to avoid this from happening when you're away for a while. Well, you should install a program that can lock your mouse and keyboard, so that any keys or buttons pressed will be ignored by your computer.

Kid-Key-Lock is the answer for this. You can download and install this program and then run it. It will work in background, hiding in notification area of your taskbar. When it's running you can activate it by clicking the icon with your mouse. If you have even locked the left mouse button, you can do Kid-Key-Lock program setup by typing: kidkeysetup (default). You may change the word "kidkeysetup" with your own word, but don't forget. To quit the program you can type "kidkeyquit", so that all locked keys will be normal again.

But remember that this program does not work as a security program. It helps you to reduce annoyance cause by your pet or your kids only. It just locks your keyboard keys and mouse buttons. Download it for free now!

PS/2 port on Mainboard malfunction

The drawer of a computer table (where the keyboard is put) should be carefully pushed back after using the computer. Recently there's someone I knew who unpurposely pushed the drawer a bit too hard and that caused the keyboard to drop down through the hole behind the drawer. Because the drawer was not entirely closed at the inside. This caused the keyboad and mouse become malfunction.

I was very surprised, how come the fall of the keyboard could cause both the keyboard and mouse to be malfunctioned. Really strange. I thought perhaps the main cause was because of the connector of the keyboard on the mainboard PS/2 slot was pulled down. Of course, this could probably be the main cause of the defect.

I tried changing the keyboard and mouse BUT nothing happened. They just didn't work at all. I began to worry whether I have to change the mainboard, just because of this small incident.

Then I realized that there's a connector that we can plug into the USB on the mainboard and the other end of the connector is the PS/2 slot for keyboard and mouse. I bought it and installed the connector. The connector worked perfectly. Luckily, I can still have PS/2 ports without having to change my mainboard. I just spent US $2.50 for the connector.

Actually, there's another solution. That is using USB keyboard and mouse. But the cost should be at least around US $10.
