The keys: 9 / O / L / . are not functioning. all surrounding keys work for except these 4 keys is there something locked or is there a function key i can press to make them work?

These keys share a scan line in the keyboard. There is a break in the scan line or a bad connection between the keyboard panel and the controller circuit board inside the keyboard (or the motherboard in a laptop computer). Most keyboards use a pair of flexible plastic sheets with the scan lines printed in silver ink. These are attached to the controller with a "flexible printed circuit" connector. Sometimes the material tarnishes where it makes its connections there and the keyboard fails as you have described.

Most of these connectors have a friction lock that is disengaged by sliding it about 1 mm along the length of the flat ribbon cable going into the connector (there is a stop at this point - do not force the lock past it). The lock looks like a frame around the top of the connector box and has a slot for the cable. Once the lock is disengaged, the cable will slide out. Now you can clean the contacts on the cable (both sides) by polishing them with a white pencil eraser. When that is done, seat the cable back in the connector and push the lock back in until it makes a soft click or bottoms out on the connector shell. Once in a while there will be a connector that is friction fit - there will be no lock, but the cable will have a stiff reinforcing sheet attached to it. Very rarely, the lock will be a flip-up tab on the side of the connector - these are usually used only on smaller, narrower ribbons.

Avoid touching the circuitry on the controller board - it is easily damaged by static electricity.

If this doesn't work, you'll probably have to replace the keyboard.

None of the keys respond

It seems that the connection of the keyboard is disturbed.
Check the TOP Lights which are on the key board. If the num lock is working then it shows key board is fine with the connection or check the connector

Some keys in keypad not working

This generally happens in all notebook keyboards. The life of these keyboards are very short. I once had a Dell system which gave me the same problem. For that I removed the laptop case and reached its main board. In the main board, there will be a cable which connects the keyboard component to the mother board. It will be a thin ver very flimsy flat transparent cable which goes into a kind of slot of the main board. Remove the cable and reinsert again firmly. This may solve the problem. If not, then the keys of the keyboard would hav lost its life in such case you have to go for a new keyboard component from the manufacturer.

HP DV9000 ''G'' ''H'' and backspace keys seem to not work on occasion

Sometimes the simplest things cause us the most grief. A starting point might be to turn the laptop upside down (be careful!). Then, use some compressed air (Dust Off, etc) to blow the keyboard. If there is trash in the keyboard, you might just blow it out -- and fix the problem.

If that doesn't work, you might consider having the keyboard replaced. I normally take them off the laptop and hit them with compressed air from the back before replacing the keyboard. That's an option you should pursue only if you feel comfortable with minor dis-assembly of your laptop.

I hope this helps. If it does, please rate the solution offered. My goal is always FixYa or Helpful, never TFT or IA. Regards,

The "i" key failed after a coffee spill. want to replace keyboard

No need to replace keyboard. If it really failed than none of the keys would work. Unplug it, turn it upside down, unscrew all the screws, open it up, clean top of he contact board with cloth dipped in alcohol. You can wash plastic parts and membrane manually in warm water with dish washing detergent. After that, wrap it in towel to dry. You can use a hair dryer but from a distance. Drying can take hours unless you work in it. Than just put all back together and screw back the screws. Plug in keyboard.
