a problem with the keyboard on presario CQ56 laptop

This problem is on a HP Compaq Persario CQ56, OS Win7 Home 32bit. All the (F) keys are acting like the FN key is been held down when it isn't. This just started today. I have a free prog called "keyboard test utility". Now I found out I can get 1 clean tap of F4 and the keyboard test prog only shows F4 lit up. The next time I hit F4 the letter (P) and the Windows key are lit up. Now if I tap the FN button then tap the F4 button. Again F4 is the only 1 that is lit up on the test prog. It is almost like the FN button has flipped over. I just confirmed it. Instead of holding down the FN key to get the things under the (F) keys (like volume -, volume +, mute and so on). Now I have to hold down the FN key to get the regular F1 to F12 keys. The rest of the keyboard is fine. On a regular toggle switch or a push button switch in a radio. The FN key is acting like someone pulled off the wires from the back of the switch and reversed the wires so the switch will work in reverse. Beats me how that can happen to a laptop keyboard.

You may have to learn, starting from the beginning on keyboard function.
There are problem to over-right some features.

F4 is most common and this is to close any window screen by hold Alt + press F4 to close the windows.

Read the manual and see how to change the layout.
