My keyboard wont type


Restore a Laptop Keyboard b> When a keyboard stops working, has odd key letters, stuck keys and non-functioning keys for no reason at all, the laptop may have an easy fix solution. However, if liquid spilled on the laptop or the laptop was dropped and as, a consequence, the keyboard doesn't work, or the keyboard device has simply failed, fixing the problem may require a more involved laptop keyboard replacement.

Click start control panel keyboard hardware make sure you have the right keyboard selected or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers Click start control panel administrative tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver if your computer came with a motherboard disk the drivers could be on it. If its still not working Tap the "Alt" and "Shift" keys simultaneously if you are pressing one keyboard key and getting a different symbol or letter. This will reset the keyboard defaults on some laptops. Press the "Ctrl" key and tap the "Shift" key simultaneously if the procedure in Step 1 did not work. Press the "Fn" and one of the "F" keys to disable the "Num Lock." Different laptops use different "F" keys to disable the "Num Lock." Toggle each "F" key and press the "Fn" key at the same time to find the right key combination. Check your laptop manual to find the right key combination. Press the "Fn" key and the blue "NumLock" key simultaneously if the keyboard is typing numbers instead of letters or wrong letter keys and the above steps did not solve the problem. b> Keyboard Maintenance b> Blow compressed air in the cracks and crevices of the laptop keyboard. Sometimes dust and debris can cause keys to lock, making such keys non-functional. Disconnect the laptop from the power outlet and remove the battery. Make the tip of a cotton swab as thin as possible by rolling it between your finger tips. Dip the thinned cotton swab in rubbing alcohol and clean the crevices of the keyboard with the cotton swab. Continue cleaning between each key of the keyboard with the alcohol-dipped cotton swab. Use a new cotton swab whenever necessary. Slightly tip up one side of the laptop so dust will move from under the keys to the crevices so you can clean. Blow compressed air into the keyboard again as you did in Step 1 of Section 2. Reconnect the computer to the power and check to see if the issue is resolved. Insert the flat edge of a flat-blade precision screwdriver under a keyboard key and gently pry it up and off. Remember where the keys go, so you can easily replace them. Remove three keys at a time and clean with a cotton swab dipped in alcohol. Replace the keys and remove the next three. Do this until the entire keyboard has been cleaned. Disconnect the laptop from the power outlet and remove the battery again. Turn the computer so the rear is facing you. Remove the screws that hold the plastic hinges in place. Insert a small flat-blade precision screwdriver in the plastic hinge seam and pry the hinges up. Turn the computer back face forward and open the screen as far back as it will go. Continue lifting the plastic hinge and power plate until it comes off. Remove the screws you see holding the keyboard with a precision Phillips screwdriver. Blow compressed air under the keyboard. Lift the cable connector levers slightly and remove the data cable. Clean the cable pins with an alcohol-dipped cotton swab. Replace everything, power on the computer and try the keyboard again to see if the issue is resolved. b> Keyboard Replacement b> Connect an external keyboard to the USB port on the laptop and verify its working condition. Disconnect the external keyboard and verify that the keys on the laptop are still inoperable. Disconnect the laptop from the power outlet and remove the battery. Remove the laptop keyboard as you did in Step 3 of Section 2 by removing the plastic hinge and power button plate, the keyboard screws and disconnecting the data cable from the motherboard connector. Replace the keyboard with a new laptop keyboard for your laptop make and model.

sounds like a faulty keyboard to me, I recommend removing the keyboard, and blowing out the connector with a can of air and reinstalling the keyboard. if that does not work I would connect a USB keyboard to make sure it is not a setting. If a USB keyboard is working fine, replace the keyboard.

How to turn off blue keys for an Compaq mini cq10??


Hi,

if you are refering to the blue letters or alphabets which are present on the keyboard. HP designs keyboard with a billingual layout in some Notebook models.

The HP "Blue" keys are indeed the "French" input keys or other language keys.

How to use the Blue Symbols or keys on a HP Notebook:

We can activate them by pressing Ctrl+fn+right Shift.To deactivate, press Ctrl+fn+right Shift twice, i.e. Ctrl+fn+right Shift then let go off Shift while still holding Ctrl and fn, then press Shift again.

When you press Ctrl+Fn+Right Shift it will switch to the the billigual layout. That means the blue characters become prioritie.

For example, if you are in the billingual layout, when you press shift+6 you will get a '?' but not the '^' sign.

I have a hp laptop model no dv 2046 tu...the problem i m facing is that my keyboard's ctrl key is stuck...whenever i press any key....a combination of that key wid ctrl is is taken...example....if i press...


This solution is for Windows XP.
If you see no physical sticking, then you may have "Sticky keys" on.
To look to see what your "Sticky Keys" Settings is at do the following:

In "Control Panel" double click "Accessibility Options"
A new window will pop up. The first tab is "Keyboard".
The first box at the top is "Sticky Keys" make sure that is unchecked.

"Sticky Keys" can be automatically turned on if you hold down certain keys for a predetermined length of time. Usually a box will pop up asking if you want to turn it on.

Thank you.
Please rate me.

Keyboard problem with an Asus Pro Series 31: Running Vista Premium


Hey,
According to me one of his keys is function keys (like : Fn,Ctrl,alt,shift) is stuck or gets stuck now and again , so whenever in msword u try and type nething its actually getting pressed ctrl + something, and hence weird functions keep on popping.
This generally happens either when he has spilt milk/water ne other liquid onto the keyboard, Solution to this would have to replacement of keyboards(Some keyboards are designed in such a way that liquid can be removed from then but i don't really know how).
Another reason would be over/improper use of the keyboard and particularly those keys causing them to get stuck
solution in such a case would be to remove the particular key and try cleaning it.
This problem is pretty common in laptops all you can do i use more carefully...i dont think there is any fool proof solution.
Cheers
