Hello

Have you tried another keyboard? What troubles me is you said that lights blink when you unplug and replug it in. This jack was never intened to be hot swappable (meaning plug and unplug with power on. I hope the only thing wrong is the keyboard else you'll need a serviceperson to diagnose the motherboard.

How do I enable a compaq laptop's keys


Compaq Presario computers provide users with a row of function keys for added keyboard functionality. Function keys can serve a dual purpose as well.
Function keys are located at the top of Compaq Presario keyboards.
By learning how function keys work on a Compaq Presario you can take advantage of time saving keyboard shortcuts.Purpose
Use function keys to access menus, save changes and create shortcut keys.
Various applications, including Microsoft Office, allow you to select a function key as a shortcut key for running specific tasks. These settings are usually found under the Tools, Settings or File menu.
Each Compaq Presario computer has twelve function keys.
The most common used keys are "F2," "F8," "F10" and "F12."
The first three are used mainly to access and use the Compaq BIOS. "F12" is used to access a set of run from options during the boot process.

How to Access
Access function keys on a Compaq Presario by pressing any of the keys on the top row of the keyboard. Access the key's dual purpose by first pressing the "Fn" key located on the bottom row of keys.
Use function keys as shortcut keys by pressing them anytime while in the desired application. Remember, you must set them as shortcut keys first.
Note that some programs may already have certain function keys set as shortcuts.
Open menus and view the shortcut keys beside each menu item before setting your own shortcuts.


Dual Uses Each function key has a dual use. Press "Fn" plus the desired function key for the key's other use.
Below each function number is a small picture within a square or rectangle.
This dictates the dual use. "F1" opens help and support. "F2" serves as a printer shortcut.
Open your homepage by pressing "F3."
If you use dual monitors, switch between monitors by using "F4." "F5" puts your computer in stand-by mode.
Quickly lock your computer by pressing "F6." "F7" and "F8" adjust the screen's contrast.
Play and pause your music in Windows Media Player or other default media player by using "F9."
Press "F10" to stop playing media. Skip ahead or rewind media by using "F11" and "F12."

Other "Fn" Keys

In addition to function keys, the "Fn" key is also provides other keys with a dual use.
Any key with a small square on the key has a dual purpose such as the "scroll," "insert" and "delete" buttons.
Since laptop keyboards have no number pads, certain keys serve as the number pad by pressing the "Fn" key.

Hi,

I believe blinking lights on the Caps and NumLock means that there is a problem about the Hardware, I've been a Tech Support for HP and those blinking lights are problems for Video Card, CPU, Memory.
It would be better if you call the manufacturer try if they can service your machine.

Hope it helps. =)

Mouse works, keyboard won't..plugged in another mouse, it works,keyboard wont..how do I tell if it's the keyboard or the tower? Husband says its the tower.


try to plug the keyboard in another computer. If it is analog the lights dont come on the keyboard (caps lock, NUM lock, ect.) it is the tower if the lights do not turn on, it is the keyboard. If your keyboard is USB then try to use it on another computer if it doesnt work it is the keyboard, but if so I would make sure any software the keyboard came with is installed and try it agian.
