My keyboard just stop working. its a hp compaq presario. the keys are not functioning

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.

I suspect that your keyboard has developed and fault and needs replacing. This can happen, where a block of keys stops working. You will need to arrange for a replacement keyboard to be fitted.

I experienced the exact same problem you posted! I found the following post on this HP website.

The HARD RESET steps listed in the solution fixed my Compaq CQ60 laptop keyboard! Good luck!

If the keys are broken, they can be replaced. It is also possible that the keyboard cable is partially unplugged from motherboard. contact +919811049801

its either a bad connector, connection, or a bad keyboard, if you had a spill, then its the keyboard, a new keyboard will fix the problem.

open the laptop and bring out the keyboard .
whash it with Alkohol and after 20 minuts dry it
and after 3 hours install it and test.
if dosent solved i have it .i can send u

If its happening on multiple pc's you might want to call the manufactor and find out if there was a recall on your pc. Yoy can clean the keyboards but usually won't solve the problem because the keys themselves have square or round bubbled popouts and when they break well you get dead keysso you can either replace the keyboard or if your a handyman find some springs and place them underneithe the keys themselves BUT DO NOT remove the bubble for it will act like a buffer. Hope this helps.

Good Luck =)
