A HP laptop without an operable keyboard won't get you very far in your day to day attempts at productivity. While you benefit from at least narrowing the cause of your computer woes to your keyboard, there are still a small number of common possible issues that may be afflicting your HP laptop keyboard, ranging from outdated drivers to keyboard cable connection problems. Fortunately, you can repair all such keyboard problems no matter your experience level.
Check to ensure your computer is properly plugged in and no cables for the HP laptop have come loose. Ensure that the AC adapter has been plugged into the back of the laptop and that it is secure in the wall socket or other power source. Reconnect it if it has become disconnected.
Download new HP keyboard drivers (see Resources). The drivers for your HP laptop keyboard may be outdated, which can result in operating problems. Ensure that your HP keyboard is up to date by downloading these drivers and then double clicking on the file to install it on your laptop. Remember to restart the computer before testing your keyboard.
Check the HP laptop keyboards cable to see if it has become disconnected. Flip the HP laptop over and remove all the screws on its back marked with a small keyboard icon. Use a Phillips head screwdriver to perform this task.
Flip the HP laptop back over and remove the keyboard shield. This shield resides at the very top of the keyboard but is separate from it, and sits under the bottom of the monitor. Use a flathead screwdriver to pry under the edge of the shield and pop it out.
Pull the HP laptop keyboard gently and partially out, just far enough to reveal the keyboard cable coming out of the base of the laptop. This cable runs from the bottom of the keyboard itself to the keyboard cable connector at the base of the unit. It should be securely plugged in here. If not, plug the cable back into the connector at the base, and lock the connector down. The "open" position for the connector is when it is upright and vertical. Clamp it down, horizontally to lock it.
Remove the keyboard altogether from the HP laptop and replace it with a new one if refastening the keyboard cable does not work. Disengage the cable from the cable connector by popping the connector into the vertical position, then pull the keyboard out and lay it aside. Plug the new keyboard into the connector, position it inside the HP's housing, then replace the shield and the keyboard screws.
