T8100 keyboard, some keys failed or cause menus to open

Due to virus,worm,or something bad, I did a full reformat and load of XPpro. Seemed to work fine but I found that the letter "L" did not work. Loaded drivers from an eBay CD but still no "L". Reform and reload OS and now the letter "U" doesn't work. Lucky the install code didn't have an "L" or "U" in it. Keying the "u" opens an accessibility menu.
Haven't tried but am sure and external kybd will work since that's a OS function (isn't it?) Did manage to get network card installed during one effort but at present I have no download capability direct to this machine. Can download and burn on desktop.
Any ideas.

Hi
In my opinion you should first try to pinpoint what the problem can be and if there is some malfunction of the keyboard. It will be very interesting to know if there is the same problem with external keyboard.
If you reinstall OS using Recovery CD there should not be any problem except for a defective keyboard. Please try with external keyboard if you have one.

Hello Momma4952
Welcome to the HP Forums!
I understand that some keys on your computer keyboard have stopped working. I will do my best to help you out! First, please provide the following information:
1. The computer's model number. If you require assistance locating this information, please reference this website: Guide to finding your product number
2. The computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
3. Have you installed any new hardware on this computer, before the issue appeared?
4. Have you installed any new software or drivers on this computer, before the issue appeared?
I would also like you to attempt the following test: Connect an external keyboard to the computer and see if the keys on that keyboard work. If the keys do not work, then we are absolutely certain there is a software/driver conflict. Otherwise, there is the potential of a hardware failure.
Thanks for posting on the HP Forums. Have a great day!

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!!!

HT3964 Backlit keyboard: some keys are brighter than others. Can this be fixed?

I spilled a small amount of liquid on the key board, but I quickly dried it and everything works fine except the keyboard. Some keys are brighter than others, what should I do?

Hope that it is the only problem that you will have with your MBP. Liquids have a habit of quickly migrating and you may or may not have gotten it all. I would take it to an Apple genius bar and have them check it out. That does not mean that your MBP will not suffer a premature death.
As far as the keyboard is concerned, pose that question to the genius bar technician.. I suspect you will be told that the only way to rectify the problem is to install a new one.
Ciao.

Bluetooth Keyboard - Some key don't work

Hi friends,
I have a 2011 (intel based) 27'' iMac with the bluetooth keyboard. I have two non working keys (control and 1).
There's a way to repair it? My iMac doesn't have warranty and I would like to repair it. What can I do??
Note: I remove the key and see everything fine, but still don't work.
Sorry for my bad english.

Keyboard - some keys not working? (Didn't spill anything though)

Hi - I am a new apple user (iMac Intel core 2 duo 24" screen) using Mac OS x 10.4.11 operating system. I have been learning it for about a month now. All of a sudden, only "some" of the keys won't work on my keyboard. THe numeric pad keys for number 4,5,&6 do not work. If you press them, nothing happens. Also, more importantly, the right "shift" key doesn't work. I am the only user and nothing was spilled on it. It has been working all along, and nothing was changed. Just to be sure, I checked the keyboard, mouse, shortcut, etc. settings, and everything (that I know of) is set right. Any idea what it could be?? Also, what is the best way to learn everything you can if you don't know a lot about the mac? The classes they offer? or ?? Thank you so much

Hi, welcome. As for the keyboard take it back to an Apple store/retailer and get it exchanged if under warranty. I have not heard of those particular keys just not working. The best way to learn about the mac is to...use it. Assign yourself some projects, play some games. There are lots of trial/freeware programs if you don't have the latest photoshop or quake. You'll run into things you're not sure about so that is where you'll learn. Check your systems Help and/or ask questions at the appropriate forum. Have fun.

Keyboard - some keys need heavy or repeated stroke

My "c" and "-" keys have not been reliable. They need a heavy stroke, or repeated strokes. Is there a way to clean the contacts of the keyboard keys? I don't want to buy a new keyboard for this problem, but it is slowly getting more prevelant.

The actual contacts are sealed between layers of plastic, so it's impractical to clean them. If you are lucky, you may just have some debris around the rubber dimple that does the pushing. You could try removing the keycap and inspecting the scissor mechanism and dimple.
Here are instructions for at least replacing the keycap, which infers how to take it off. http://support.apple.com/kb/HT2310

Hello bungalow2014
Check out the article below for further troubleshooting options for your keyboard. One other thing to check is to open Keyboard Viewer to see if there is anything else being pressed while hitting those keys.

Apple Wireless Keyboard - some keys not working with iPhone 5

I just bought an Apple Wireless Keyboard (2011) and paired it with my iphone 5 (iOS 7.0.3).
All keys work except the following:
Space bar
Delete
Caps Lock
Down Arrow
Tab
I can understand if iOS has no concept of Tab, but Space and Delete are essential.
Did I get a bad keyboard?

IMac G5 & new apple keyboard - some keys not working

I have an iMac G5 (2GHz, 20 inch), running OS X Tiger (10.4.11) and I recently purchased the new apple keyboard (the wired version without the numpad, to save desk space). I am finding that the function keys at the top don't work - specifically, the keys that control sound. I've googled this, and installed the Keyboard Software Update 1.2 that most people said fixed their problem - but it hasn't fixed mine.
Instead, the f10-f12 keys don't control the sound functions, but the f12 key ejects discs (it sits next to the eject button, so perhaps this is a wiring error?), and the caps lock key does not always work when hitting it - it needs a large amount of pressure. I would think that my keyboard was defective, but I just exchanged it yesterday, and the new one has the same problems. I'm getting close to just giving up and getting a refund.

Hello - thank you for the quick responses! To answer your question, yes, I have repaired my permissions and restarted, to no avail.
I have looked through the keyboard prefs quite a bit, and cannot find anything that allows me to choose where to map the sound keys. I have checked "Use All F1 F2 etc keys as standard function keys". In the small aluminum keyboards, the f keys are dual-function - in this case, the f10-f12 keys also control dashboard, etc, which I have turned off (but I have tested the keys with these options both off & on, with the fn key, without the fn key, etc - tried lots of combinations). I've tried quite a few things to get these keys to work. Honestly, the f1-f4 keys don't seem to work at all either.
I might try and take a video later today to show you what I mean. The caps lock key is the biggest thing that's bothering me - I use it instead of shift to type, and 75% of the type it does not activate when pressed...I would think this was just one bogus keyboard if it weren't for the fact that I already exchanged it once...

When composing mail in Gmail, certain key combinations cause menus to open or new documents to be created?

While typing "sh" or "th" etc combinations menu's open on their own. The history menu comes up with "sh". When "th" is used, it opens a new document. Very bothersome. How do I disable this?

Problem is solved by removing these 2 lines from iframe.html
if(navigator.appName=="Microsoft Internet Explorer")
document.location.replace("");

HT1338 Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.

Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.
This blinking occurs when no keyboarding is going on.
Back-up is not running.
I am on-line.

Anthony:
The normal practice is to use the Shift key when typing a single Capital letter, as in a name or the beginning of a sentence, and the Caps Lock key to type all caps. The easiest thing would be for you to retrain your little finger to use the Shift instead of Caps Lock. I know of no way to display an icon at the bottom of the monitor to display that the caps lock key is engaged.
