Water damage??????????/ I don't know whta happened but the key pad and the side buttons stopped working except for the on and off button... what could be the problem?

You probably need to call the manufacturer. Sorry, no other ideas.

To access Mouse Properties, select Start - Control Panel - Hardware and Sound -Mouse.

Use Mouse Properties in Windows to customize settings for pointing devices, such as button configuration, click speed, and pointer options.

Check the water filter

Possible there is damage to the pad or the base board. Unless this is opened and cleaned the board damage cannot be confirmed. Also use a hair dryer to warm off any moisture that can cause this malfunction

For many cell phones, the buttons are the main way -- and sometimes the only way-- that you can interface with the device. Most cell phone buttons are simply small domed pieces of metal that flatten out when you press them, completing a circuit with a metal pad on the circuit board and allowing the software to register a keypress. If you need to fix buttons that have stopped working, you'll first want to try some simple fixes, but you will probably have to open up the device.

1.Remove the device's battery, wait about 20 seconds, then replace it. Software errors sometimes interfere with the keypad operation. Removing the battery will reset the software and if the buttons start working again, you will have saved yourself a lot of effort.
2.Take note of which buttons are not working. Once you have the device apart and are staring at the internal keyboard, it may be difficult to remember exactly which buttons are non-functional.
3.Remove the cell phone's plastic housing so that you can get to the keyboard. The exact method for doing this will vary widely based on your exact model of cell phone, but most will have small Phillips or Torx screws on the back side. Once you've removed the screws, use a pry tool to separate the housing and get to the keyboard.
4.Check the rubber keypad for damage. This is the part that contains the keys you actually press, the underside of which will have a small cylinder under each key. When you press down on the button, the cylinder pushes down on the actual keyboard. Any damage to the keys on the topside, or to the cylinders underneath, can cause an individual key to stop working. If there is damage, there is no way to fix it -- you will have to replace the rubber keypad.
5.Check the connector that runs from the keyboard to the rest of the circuit board to ensure that it is seated correctly and is not damaged. If it is damaged, you will have to replace the entire keyboard to restore functionality. Not every keyboard will have a cable, as some are installed directly on the control board, so don't worry if you can't find one.
6.Hold the heat gun about six inches above the keyboard. Turn on the heat gun and move it around the keyboard for about a minute. Do not hold the heat gun in any one place for more than a second or two.
7.Pry up the white sticker that sits on top of the keyboard. This sticker holds the metal domes, which are what get pressed down to actually cause a button press, in place. If the sticker is not coming up, apply heat for another 10 seconds and try again. Be careful that you do not separate the metal domes from the underside of this sticker.
8.Apply isopropyl alcohol to your brush and scrub the metal pads on the keyboard, along with any nearby components on the circuit board. Dirt, debris and moisture damage can build up on the keyboard over time and eventually cause it to stop working. Cleaning it is not a guaranteed fix, but it often helps.
9.Locate the metal domes, which are attached to the underside of the white sticker, for any individual keys that are not working. Place the tip of your small screwdriver in the middle of the concave side of the dome and pull the edge toward the screwdriver. Sometimes, the domes will lose their ability to fully depress, and this process will restore this ability. Don't pull too much -- just enough to add a slightly greater curvature to the dome. Note that this process should be used only when a single button is non-functional. If a group of buttons, or all the buttons, are non-functional, the problem is elsewhere.
10.Replace the white sticker, ensuring that the metal domes are positioned exactly over the metal pads on the circuit board. Reassemble the device and try out the keyboard. If the keys are still not working, the keyboard is probably never going to function again.

I hope you find it very helpful. Best regards.

try it with toggle keys it may be work

i have the same problem, only mine was spelt in beer. oppps :( but i know this also happens to my friends phone and she told me to take the battery out for about a night or so and see what happens!! who knows, we will find out together i guesssss!

Hi,
Sometimes this happened to soney ericsson mobiles, you have to master reset then all the buttons will start functionality again.

Hope this will be answer of your question

Oh my gosh!!!! It worked!!! It really worked! I had my phone in the back pocket of my jeans when I went outside in a heavy rainstorm to get to my car. When I got to school (I'm a teacher) I realized my phone wouldn't work...except for the power button. None of the other buttons worked at all...AND...GULP....the water indicator sticker inside was red. I got my second graders busy, then looked on here for some help on what to do. I read the comment about how the person laughed, but banged the phone on her knee after reading about banging the phone....not thinking it would work...and it DID! I'm SO happy!!!! Thank you

I have the same problem. Was not dropped or water damage to my knowledge. Just the red button works. When I open it, though, it shows the asteriks key as being pressed which is under the #7 key. Any help would be greatly appeciated.
