Question about Compaq 310640-001 Keyboard for Presario notebook PC 3000

1 Answer

Scrambled keyboard All the keyboard keys are scrambled--typing the wrong key/function. Nothing was spilled on it, and I have restored it back a few days. It was working fine, and then the next time I tried to use it, everything was scrambled. It doesn't matter if I reboot, etc.

Re: scrambled keyboard

Have you tried cleaning and reseating the zif connector that connects the keyboard to the motherboard? Depending on how many cats and kids bang on the laptop, that can cause a problem. Another possibility is using an external keyboard and see if the same thing happens. If so, look to see if a keyboard program of some sort is running. If the external keyboard works fine, then you will need to replace the internal one, or just continue using the external one.

Keyboard typing wrong letters

Your keyboard is not "typing wrong letters", you have a stuck key. The key is shorting out and is stuck on the letter W. Usually caused by dirt/dust/spills on the keyboard jamming the key so it can't release. Things to try in order of difficulty:
>Vacuum cleaner with brush attachment, vac the keys.
>Paper towel moistened lightly rubbed on the 4 sides of the W key; use a knife blade to gently work down into the edges.
>Soft toothbrush, lightly dampened with water, work the bristles all
all around the edges of the W key. After that do step 2 with a dry
dry paper towel.
>Take the keyboard apart; usually several tiny screws on the rear/sides. CAREFULLY remove the top. You may have to turn the board over, lie on its face to do this. Do not knock the letters out of order or you will have a headache placing them back in proper order! Clear whatever it blocking the W and replace the cover.
If none of the above works the keyboard has failed, needs to be replaced.

My son hit a few keys and now the are all jumbled. I hit a "P" and get the "*", an "L" gives me "2". How do I fix this?

Sounds like a spill on the keyboard to be honest, but assuming that its a result of your son hitting the keyboard there may be a key stuck down somewhere.
get a knife and ensure all keys are restored back to the up lightly lifting them one by one.

A few keys on my Acer 4420 are not working properly and I have no idea as to why. The keys are my o, p, l, ' and period keys. When I do use them they type out random characters. My o keys types out i75`,...

If a neighbor will let you,disconnect their keyboard and try it on yours.If it works normal,the problem is the keyboard.They are fairly cheap to buy brand new.If it does not go away,something is wrong,most likely the IC which interprets the keyboard signal and converts it to letters.It sounds most likely to be the keyboard because it is a few characters consistently.Perhaps something was spilled in that section as they are quite close together.Good luck,Greg

You can reseat your keyboard's cable. You will need the manual of your computer to do this. If reseating the cable will not work then you may have to get it replaced.

Some keys of my keyboard doesnt work..(5,6,r,t,f,g,v)..

If they type something else instead then you need to hit the scroll lock key to release the keys. If nothing comes from typing the keys then you need a new keyboard. Best source is EBay if it is a laptop.

Return key acts as cap lock key

Go into System Preferences and select Keyboard & Mouse
Under Keyboard click on Change Keyboard Type... button
• Follow the basic steps to reset your Keyboard via the screen prompts.
Once you have done that select the Keyboard Shortcuts tab.
• Click the Restore Defaults button.

Now test your keyboard's return key. If this still does not resolve the Return key not functioning in the normal return key functionality,
Click Show All and go to the Universal Access pane in System Preferences and under Keyboard tab, make sure the Sticky Keys radio button is turned off.

Try these steps and let me know if there is any change.

Keypad not functioning properly...

Check to see if your shift, control, alt, or other modifier keys are stuck on your keyboard. These can cause your keyboard to act erratically. Also, if this is a wireless keyboard, you may need to change the batteries, as this can also cause a keyboard to act erratically.
