Question about HP Pavilion N5150 Notebook

Keyboard keys refuse to work

All of a sudden yesterday certain keyboard keys on my laptop stopped working. When I press keys q, w, e, r, u, i, o, p, they refuse to work. Basically the entire top row of letters (excepting t and y in the very middle) is out. Also the up arrow key and the right shift key do not work. I am thinking it may be a problem with some lock function, since we have done some fiddling and it does not seem to be a hardware problem...though there is one more test I need to run to make sure of that, it does appear to be a software problem. I have never dropped this computer--I treat it very carefully and have never had a problem like this before. Can anyone help me?

    So I've heard...however, the keyboard mysteriously started working again last night after I shut it down for the fourth? time, I think.

    Initially we ruled out hardware because the keys did start working again for maybe 30 seconds while we were fiddling with it...but maybe it's something in the circuitry? Plus, it wasn't the whole row, and those other two keys are in a different part of the keyboard, so I'm frankly bewildered by the whole thing. Why should it take out just those keys? I found one other case on the HP IT website where the same thing had happened (though the user did not mention a shift or arrow key problem) and she said it happened "intermittently." So I'm wondering if this is the first time of many...

    all of a sudden after being shut down, the bottom 2 rows of my laptop (HP dvv6000) stopped working with the exception of g, h, b, & n. the numbers and top letter row all work. Ive rebooted several times, taken out the battery several times and still nothing is working... can anyone help me? Nothing has been spilled on it either....

Generally when a row goes out the keyboard is shot and needs replaced. How did you rule out hardware issue?

    Again, how did you rule out hardware? The keyboard is a plug and play device, no software. The only way to rule it out is to connect it to another machine and try it. This is a hardware problem. If not with the keyboard, then the motherboard, but still a hardware problem. Check the connection for dirt or corrosion build up.

    It's very possible that it may have just had a temporary glitch, this happens. The connector could be loose or have a build up. Or it could possibly be an indication that the keyboard is on it's way out. Time will tell.

Have you pressed/un-pressed the NUMLOCK key?


You may have a stuck key somewhere on your 10-key numeric keyboard. Sometimes dirt (coffee, dust, soda) is blocking the contacts to the circuit board from the keyboard.

Delete key stopped working

One moment you are typing on your computer keyboard as usual, when suddenly a key sticks or does not produce a character on the screen.
Perhaps you have a group of keys that suddenly stop working.
Laptop and desktop keyboards alike can stop functioning due to a number of causes, most of which can be resolved by troubleshooting.
Knowing how to fix some keyboard keys that do not work can save you time, and save you the cost of buying a new keyboard.

Disconnect and reconnect your computer keyboard, then restart your computer.
Sometimes a poor connection can result in keys not working on your keyboard.
Update the device driver for your keyboard by going to the manufacturer's website of your keyboard, and then download and install the latest driver matching the brand and model number of your keyboard.

Disconnect your keyboard from your computer and inspect the pins in the keyboard connector if you have a PS/2 connector.
The PS/2 connector for your keyboard has six pins, which connect into a PS/2 port of your personal computer, to allow for communication to and from your keyboard.
Straighten any bent pins you may find, by gently using a ballpoint pen. You must replace your keyboard if you see broken pins.

Try testing your keys using a different application, such as another word processing program. Keys like the function keys on your keyboard labeled F1 through F12 may not work in one application but will work fine in another.

Clean Under Desktop Keys

Disconnect your standard desktop keyboard, then press down on a key not working.
Slip a car key or a flathead screwdriver underneath the key.
Twist the screwdriver or car key until the keyboard key pops off.

Use a damp cloth, moist cotton swabs or compressed air to remove dust, hair, and food crumbs under the key.
Use only water or rubbing alcohol to moisten the cloth and cotton swabs other cleaners can damage the plastic of your computer.

Position and press down on the key to snap it into place.
Repeat this for all of the keys to clean underneath them, if necessary.

Clean Under Laptop Keys

Turn your laptop off, then use a flathead screwdriver or knife under a key corner, prying the key off gently.
You will hear a snap as the key detaches.

Remove the key retainer remaining on your laptop using your knife or screwdriver under the corner, then popping it off with a gentle twist.

Remove the space bar by pulling it off after your insert the screwdriver or knife underneath the bar.

Clean underneath your laptop keys using cotton swabs or a soft cloth dampened with water or alcohol.
You can also use compressed air to remove dust, hair and other debris.

Replace your laptop keys by placing the key retainer into position.
If you cannot remember the position, copy another retainer's position by removing another key.
Insert the keypad into the retainer, then position the key over the retainer while pressing down on the key.
You should hear the key snap into place.
Place your laptop's space bar over the space bar slots, then snap it into place.

Saitek Eclipse Keyboard Keys stopped working

this could very well be your OS as much as your keyboard. Try another board for a few days and see if it still happens. IF found your culprit. Replace the keyboard or look for updated drivers if they exist.

Unresponsive key board

Most notebooks have touch sensitive pads or switches underneath the keyboard, unlike a normal keyboard which is less complicated. You can try and remove keyboard and check underneath, but it may be that the circuitry that works certain banks of keys is damaged or shorting. Not a job for faint hearted i would recommend a qualified repairer.

Certain keys won't function on keyboard

Could be that the connector from the keyboard to the mainboard is crooked. Try taking the keyboard off and wiggling the connector from the keyboard to the board so that it is a snugger fit.
