Few keys not working

Hello,
I spilled some water on my hp Pavillion g4-1200 tu Notebook PC about a month ago. I wiped the water immediately but since then I have been noticing that some keys have become hard to press and yesterday some keys even stopped working. At times some keys works and at times they dont. Please help me as I have already cleaned my laptop and have also used a hairdryer to wipe of the dust but it is not working as such. I tried using the driver scanner on hp's website to see if the laptops drivers were up to date even that didnot work successfully though the keyboard driver is up to date.
Thanks

The keyboard is mechanically damaged, no driver will fix your problem. Unless you have skills in cleaning keyboard internally , you are set to buy a new keyboard and install it.
Check your laptop technical manual for more details

A few keys not working - faulty keyboard?

Hi,
A friend of mine (honest!) spilt a v.small amount of water on her keyboard on her 2.16ghz 17" MBP and decided to dry it out using a hair dryer.
One melted keyboard later and I was asked to replace her keyboard for her.
So having bought and fit a new keyboard, keys are not working and 1 is intermittant. These keys are: f10, f11, 0, - and p ([ is intermittant).
They are all grouped together near the top right of the keyboard.
Twice I have tried to ensure the keyboard ribbon cable is firmly in place and it seems to be. Is the new keyboard I bought likely to be faulty and there needs returning, or could this be some other problem.
Thanks in advance for all your thoughts!
Dominic

Did the new keyboard come with a new cable? You might want to carefully examine the cable under strong magnification and look for any breaks that might correspond to the keys that are not working or not working properly.
Also, try an external keyboard. If you have the same situation on an external, there is some problem other than the replacement keyboard.
For future reference for your friend, you NEVER want to use a hair drier on a water spill. The best thing to do is to turn the Mac off, remove the battery, and lay it keyboard down on a towel for several days. You want all the water to drain out and any internal residue to dry completely before putting power to the machine again. Most of the time, the water will dry and everything will work again.
The forced air from the hair drier could have blown water deeper into the machine and there could be some residue causing problems. When you take the machine apart to check the cable, also check for any remaining moisture that could still be causing problems. If the machine had not been allowed to dry for several days, it needs to.
Good luck!

Curve 9300 3G - A few Keys not working properly

Somebody close had gifted this Blackberry Curve 9300 3G mobile to me. After using it for just 2 months, the Space, alt and 0 keys are not working properly. At times I just have to keep pressing for these respective keys to respond and at times upon pressing, these keys respond more than once. Does anybody know how to tackle this issue.

Some keybaord keys not working after suspect virus on Tecra A

Apostrophe, delete, semicolon and end keys not working after a suspected virus attack. I found record of the same problem on the net but apparently this guy fixed his problem after he found scroll lock or num lock on.
This is not the case here but there is something going on with numlock - register shows 2 and not 0. change to 0 but when reboot back to 2 again.
Suspect changed back by bios. I thought i couldnt get to bios because DEL key not working but found ESC works.
Tried to reset default values for bios but then cannot save and exit as this required the END key to work.
I was running XP at the time of the (suspected) attack and could not rectify the problem so put the computer back to the OEM status which i hoped would help - it did not, same problem so rather than install all the software on the computer again with XP i upgraded to Windows7 - fresh install.
Still keys do not work - it was a real pain to start with as my computer was set up to ctl+alt+del to log in and i had to do this with on screen keyboard - XP - this also showed that numlock was on before and after windows boot.
The reason i suspect a virus - my wife was watching one of her tv shows on line from home country (another toshiba laptop) and i needed to use that laptop for something else so i asked her to use mine - later on we turned the laptops off and in the morning turned tham back on again, the other laptop with AVG virus protection flagged several hits and this one with (FAMOUS and completely up to date) Norton flagged nothing - once i got into it using on screen keyboard.
Problems with this computer was found after scanning with a different antivirus.
Anyway - i am left with 4 keys that do not work on my keyboard (actually they did work after i logged into the computer for the first time but i had to hold them in for a long time - and then next time i rebooted, not work at all and havent ever since)
Any assistance here would be greatly appreciated, i have been working on this all weekend with no joy at all.
Thanks in advance.

Thanks Xardas,
I have essentially done both - tried Toshiba OEM status found on a small partition of the toshi hard drive - no good - then did a fresh install of Windows 7 - still no good
You know - as cunning as it sounds - i cannot reload the default settings in BIOS as it requires the END key to work so i can Save & Exit - all i can do is Exit Without Save - i sort of feel snookered at the moment.
Toshiba got back to me today and said that i have tried everything they would have (yeah for sure) and to take my machine into a service centre for a hardware check - yeah right on boys!
Check out this guys post below found on Kioskea.net - getting close to a year ago...

Hi there, I was hoping that you might be able to help me with the problem that I seem to be having with my Toshiba Satellite Laptop Keyboard too. For a few days now I havent been able to use a few of the keys on my keyboard, including (1) delete (the backspace key is still working though), (2) colon/semicolon, (3) apostrophe/quotation marks and (4) end (the home and PgUp and PgDn keys are still working though). Any suggestions?
Identical to my problem....obviously this guy had the same problem as well...see below - same thread.
yab - Feb 9, 2010 4:47am GMT
hi did you ever figure this out? i have the same exact problem...
However, i was not able to solve my problem the way this guy did - my scroll lock is not activated - it seems to work ok (on and off) i tested it using Excel to move around the cells.
yab ms ml - Feb 9, 2010 7:57am GMT
Nevermind. For me it was scroll lock. My apostrophe, semicolon, and delete keys are alive and working again. I hope you have the same easy fix.
Incidently - never hear from the first guy again - probably ended up being his scroll lock.
all sugestions welcome - sorry my smily face has no eyes -) guess why!

F1, F6, F7 keys not working in RF Device - Symbol MC9090

Hi All,
We are activating funtion keys in ITS Mobile. Looked at lots of posts and included service parameters for ITSMOBILEDEVINCLUDE etc and regenerated screens (HTML Templates) using Mobile Gerate option.
Finally function keys are working. But only few keys are working like F2,F3 and F9 etc
When i press F1, standard browser functionality is coming i.e. Browser help is coming. I am not sure how to disable standard functionality and enable my screen specific.
Any help will be appreciated.
Thanks,
Jyothi

we faced the sample problem, it's caused by wavelink version, you need upgrade to new wavelink version (7.1x above).
http://www.wavelink.com/Motorola%20(Symbol)-MC9000-Emulators-downloads
The bad news is version 7.1x above you need pay licence, while MC9090 pre-installed version is version 7.0x and which is free.

Volume and brightness keys not working with new keyboard on imac

I just purchased a new wired keyboard for imac and brightness and volume control keys not working . i have tried adjusting keyboard settings. I have software version 10.5.8. Do I need to upgrade software. Thank you for any help.

Do you have "Automatically Adjust Brightness" check box ticked in System Preferences > Displays > Display ? If so, you can't manually adjust brightness.

Esc key not working in windows 7

Hi,
I have a HP Pavilion dv6-4XXX series. It's almost been 2 years I bought this notebook.
Recently I faced an issue. The "ESC KEY" has stopped working. However I could find that it's working fine in BIOS but not when I am logged in to windows. I have windows-7 installed.
Please let me know what could be the issue and the solution for the same.

Hello siddharthmishra,
You’re having a problem with the ESC key not working.
Go to device manager and uninstall the keyboard and restart the computer. This should uninstall and reinstall the driver for the keyboard.
Here is a link to device manager.
If the problem has not been happening for very long, you might try a System Restore. This will take the system back to before the problem started happening without affecting any of your files.
Here is a link to a System Restore.
Let me know how everything goes.

Command, option, ctrl, fn keys not working

thanks to a visiting dog who got tangled up the power adapter my laptop ended up on the floor, wide open with the keyboard popped out. I have inspected the connector cable and it looks OK to the naked eye. I disconnected the keyboard cable and re-connected.
When using an external USB keyboard all keys function normally. When using the built-in keyboard the only keys not working are the command, option, ctrl and fn keys. I have restored modifier keys to default (I had never changed them) but this did not help. I also toggled the "use F1-F12 to control..." option in the keyboard preferences to no avail and have restored keyboard shortcuts to no avail.
Is my keyboard shot? Is the a pref file I might delete?

Hi, Mel. If the external keyboard works properly, I'm afraid you have to figure your built-in KB has been dogged to death. I hope the pet owner will do the right thing by you. I also hope the KB is all that was damaged. How are your adapter cord, plug, and DC-In port? Does your battery still charge OK?
Whenever anything visits my house that's active, inattentive, and built low to the ground, my Powerbook runs on battery power only. I haven't seen one yet, but the new magnetically-connected, easily- and harmlessly-detached MacBook Pro AC adapters sound like a superb idea to me. Too bad our PBs can't use 'em.

Keyboard: some keys not working

Some keys not working. Need help/suggestions. Not great with computers so PLEASE give details/steps re: how to do what you suggest - thanks!
Details: intel based iMac running snow leopard 10.6.8. Apple wireless/bluetooth keyboard (came with the iMac).
Some keys suddenly stopped working: space, tab, capLock, option key to the right of space bar (one on the left works), down arrow
The problem happens in various programs (safari, pages, etc)
The keyboard is fine on another iMac
A different keyboard is fine on this/the involved iMac
(nutshell: keyboard works fine - computer works fine, unless they're together)
Here's what's been tried/checked:
-checked the settings for universal access ("mouse keys" are off) and checked for any bluetooth keyboard shortcuts.
-in system preferences "speech" is not set for "speak selected text when the key is pressed" - this is not checked/selected
-tried creating a new user but had the same issue so it's computer-wide rather than just a user account
-removed the keyboard and reconnected (using the +/- signs and "disconnect" and putting in a new code of numbers to pair keyboard)
-language/text is set for english
-did the keyboard viewer and the keys in question did NOT highlight when pressed (but don't forget the entire keyboard is fine on a different computer so thekeys aren't the issue)
-"slow keys" is turned off re: keyboard in system preferences.
Any help is welcomed. It's frustrating knowing the keyboard works, just not with this computer. Please help. Many thanks!

yes - not sure how this works...if you can see my original post there are a lot of details in there. If you can't...
nutshell: the keyboard works on a different iMac
             a different keyboard works on this/the involved iMac
             I tried to create a different user and the keyboard still does not work so it is computer-wide
             I also removed the keyboard from the computer (using the +/- symbols and disconnecting and then repairing it. The problem remained
Thanks for any help. It's crazy that the keyboard is fine and the computer is fine but together, there's the problem.
Thank you!!!

Sound key not working

volume key not working ofter last update

Hello Amandodsouza,
It sounds like you are experiencing some unexpected behaviour with the on screen keyboard after updating to iOS 7.1.1. I would start by closing all the running apps on the phone:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that and restart the phone and test the issue again:
iOS: Turning off and on (restarting) and resetting

Any help here is apprecited. My function (Fn) key is refusing to work at all. None of the special features are able to be used. I've checked all my drivers, and followed the instructions in the User Guide, but some of the options described in the guide are even showing on my computer.
I'd love for some help on this issue, as the computer is pretty worthless right now.

Return & shift keys not working

My keyboard is unresponsive. problms started w/ "L" and "9" and "Enter/Return" keys. Did a s/w update and reboot but still no success. Now only "Shift" and "Enter/Return" keys are unresponsive.

I tried the troubleshooting steps listed in the article linked above but ran into the following problems:
a) the View menu doesn't have a "Speech" item listed (I'm running 10.9.2)
b) My MacBook Air doesn't have a disk drive; impossible to start up from an Install disk as recommended in step 10.
None of the other steps helped (sticky keys off, slow keys off, mouse keys off, etc)
Looking at the forums, looks like several other people have the issue of just the right-side shift and return keys not working, like me. Could we please have some advice that is specific to that particular issue?
In the meantime I'm using only the left-side shift and have downloaded and installed KeyRemap4MacBook and remapped my backslash key so it issues the "return" command. A clunky work around but it seems to do the trick, at least.
