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.

Compaq 730us touch pad not responding


Hi
To fix an unresponsive touchpad on your laptop/desktop XP Home, XPPro:
Reactivate it by using the Function key on the keyboard and the Fn key.

This process is different for each computer manufacturer.
If unsure which Function key enables and disables the touchpad, try each one at a time and then
attempt to use the touchpad after each one.

A...Locate the "Fn" key of the laptop keyboard.
The "Fn" key has different colored text or the key is a different color.
B...Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop.
The key typically has an icon that resembles a touchpad with a finger touching it or a touchpad with a diagonal line through it.
C...Press both the "Fn" and touchpad Function key at the same time to reactive the touchpad on your laptop.
Move your finger along the touchpad to verify that it works. Press the combination at any time to disable the touchpad again.
Note: Mac computers use "F2" to enable and disable the touchpad.

Keyboard is shot. They do that due to the heat laptops generate. I've probably replaced 200 laptop keyboards in the past 5 years. You can buy one on ebay for about $21.00. http://cgi.ebay.com/NEW-HP-COMPAQ-Presario-2100-2500-Keyboard-317443-001_W0QQitemZ190124162270QQihZ009QQcategoryZ116289QQcmdZViewItem Ray
