Certain keys on my keyboard no longer work as intended

All of a sudden my keyboard isnt working as it used to. Certain keys dont work. I attempted to trouble shoot, but I also had trouble with the steps listed. I didnt have the places that it said to go to in my system preferences. I dont have universal access or speech. I dont understand what happened. Its only certain keys. For example, if I hit the apostrophe/quotation marks key I get and : or *
I restarted and made sure that my USB connection was good. I dont know what to do and its making me crazy!! HELP please!

Certain keys on midi keyboard no longer seem to be recognized -

Hi all,
I've done my best to read through all the existing posts on similar topics but haven't been able to solve this seemingly odd but probably simple issue. I'm at the end of my wits, hope someone can help!
I have been using an M-Audio Axiom 25 with Logic Pro 8.0.2 on a MacBook Pro for about a year with no problems. Yesterday, a large portion of the keys on the Axiom stopped working. The highest two notes on the keyboard register in the transport as C3 and B2, which I can also hear, but no other keys seem to generate input/output. However, the trigger pads on the Axiom generate other notes (their default assignments) normally.
In the "clicks and ports" page, the onscreen keyboard registers every note I click with the mouse, but still nothing from keys other than the two I mentioned above. I'd like to say everything looks normal in this window, but I haven't used it enough to know for sure.
It doesn't seem to be project-specific as it happens even in new projects. Also, I've shut down Logic and opened Garage Band and the keyboard exhibits the same abnormal behavior there.
In preferences ->MIDI -> general, I've clicked "reset all midi drivers" with no change. Logic seems to "see" the M-Audio device, they're just not playing nicely. Just for kicks, tried a different cord - not that either. Also, in Audio Midi Setup, I deleted the Axiom 25, shut down Logic, plugged the Axiom back in, but nothing changed. Logic still recognizes the Axiom but only those two keys (and the pads) work. In "show info", the "device is online" is checked but also greyed out.
I'd like to think that I've accidentally changed a setting, etc, but can't figure it out! I'd be supremely grateful for any help you can give. What can I look at next?
Thanks!
- Nate

Hey, thanks for responding.
I did as you suggested and checked out the Controller Assignments window. There were a few things assigned, but I clicked delete and now there is a message that reads "no assignments selected". Sadly, that did not change the situation and still only those last two keys (and on the on-board pads) register input in the transport.
Any other ideas? I'll try them! When this happened, I was on a roll that I'm looking forward to getting back to.
The only other thing I can think of to try right now is to try the controller with a different computer.
Thanks again, I appreciate your help!

The function of the F keys at the top of my keyboard no longer work as they used to. How do I restore their old function?

The function of the F keys at the top of my keyboard no longer work as they used to. The actions they do no longer correspond to the symbols that are printed on them. For example, the volume buttons no longer control volume and now change the display to full-screen instead, and the brightness buttons don't do anything at all.
This started today and I'm finding it very irritating. I checked in System Preferences and didn't find any obvious way to turn most of them back to what they used to do.
Help?

In System Preferences > Keyboard uncheck Use all F1, F2, etc. keys as standard function keys.

3rd party keyboard no longer works properly with Yosemite

Prior to the update to Yosemite my third party bluetooth keyboard paired without issue on my wizened 2007 MBP workhorse. I unfortunately spilled some liquid on the keyboard recently. A few keys no longer respond. I will be replacing the keyboard, being cheeper than replacing the entire computer. I brought out my third party bluetooth keyboard, and it initially paired fine under Yosemite. I went into the keyboard preferences to see if I could improve the key mapping with the function keys. Selected "set up bluetooth keyboard" which seemed to reset the connection. Since, the keyboard no longer worked completely. Letters, numbers, and function keys, respond, but none of the letter keys. I re-paired it multiple times to the same effect (forget - pair). The keyboard still pairs fine with my iPhone 6, with the Apple Mouse still pairs fine with the laptop. Is there any way to fix this problem? The keyboard technically is pairing!
I am using an old apple USB keyboard as plan B until the main keyboard is replaced. However, this is especially frustrating, because one of the reasons why I bought that keyboard was in case the old laptop's keyboard developed issues!

Do either of these typical troubleshooting steps make any difference?
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Command+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Firefox menu) > Preferences > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* (menu bar) Tools > Page Info > Security > "View Cookies"
* click the globe or padlock to the left of the address in the address bar > More Information > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?
In case one of your extensions is involved, could you test the page in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

I took my computer in for service just before the warranty expired now I have one question and can't get any help. The sound buttons on my keyboard no longer work

I installed the new Mavericks update on my MacBook Pro when it was released and offered free of charge. After that my computer started crashing on a regular basis, upon the realization that my warranty was due to expire at the end of the year I took my computer in to the Apple Store in Green Hills Mall about 5 days before Christmas. To anyone not familiar with Green Hills in Nashville TN the traffic is horrendous at all times let alone 5 days before Christmas. They had to send it off for service and it was shipped back to me on Christmas Eve. Through the holidays I haven't used it much. I usually just use it at work between customers and most of the time just leave it here. Friday evening I played videos with no problems, when I came back in on Monday and played a video the sound had decreased dramatically and the volume control keys on my keyboard would not work. I don't know if they were working before because I don't remember if I used them or not since Monday was the first time the volume was so low. Now my warranty is expired and I am very poor ( The I have a job, a roof over my head and food to eat but a negative balance in checking account and bills still to pay kind of poor) so I am hoping that someone out there knows what's causing this and how to fix it.

Mavericks has had a lot of compatability issues and are slowly being fixed. This is why I haven't upgraded yet.
Either downgrade back to Mountain Lion or just wait for a software fix.

Apple Wireless Bluetooth Keyboard no longer works after OSX update

After installing the latest OSX update yesterday (something about iChat encryption), Apple Bluetooth Keyboard no longer works with my iMac.
When I restarted the iMac after installation was completed, the iMac would no longer recognise my Bluetooth Apple wireless keyboard. I've tried with 2 other Apple wireless keyboards as well, but to no avail. None of them work with the iMac any longer. All 3 keyboards work with my PowerMac Quad G5 though.
The iMac "sees" the keyboards, but the pairing doesn't go through because the iMac doesn't seem to recognise the keystrokes when entering the pairing code.
I had to go out and buy myself a Microsoft wired keyboard to be able to restart the iMac (couldn't enter the login password without a keyboard).
My bluetooth mighty mouse works flawlessly though.
Very frustrating. Can anyone help?

Opened Powerbook - Now Keyboard No Longer Works :(

Hi all,
my brother asked me to upgrade the HD in his PowerBook G4 1.25Ghz. I followed instructions on iFixit and it all went well, apart from reattaching the keyboard ribbon cable. The logic board has now become damaged because one of the two clasps on either side of the plastic bracket securing the ribbon cable from the keyboard has snapped off. The ribbon cable doesn't seem to hold securely anymore and the keyboard cannot be used. The take-apart guide was a bit unclear about this; what I have is a ribbon cable with a completely stripped and exposed end which slips into a plastic bracket on the logic board and is then wedged in by a separate plastic cross-bar which clips in to the bracket using the 2 clasps at either end. Despite the fact that one of these clasps has now snapped off the ribbon cable looks like it’s pretty firmly wedged in (although it seems an uncharacteristically poor design on Apple’s part) and I’ve made double sure with a little strip of tape. I can’t see how it could be held any other way, however clearly it’s not working as the Powerbook keyboard no longer works and I have to use a USB keyboard.
I can’t figure this connection out as it looks so makeshift compared to other cables and sockets I’ve seen on Apple logic boards. Anyone have a solution to fixing this ribbon cable in so that it’s making full electrical contact as intended?
Thanks!

OK, thanks. A new logic board seems such an extreme solution, but it may be the only thing left to try
The thing is I can't really see what it is that isn't making contact with the ribbon cable. I know the clasp on one side is gone, but despite this the cable is just as firmly wedged in and tape applied over the top to ensure it doesn't ever work loose. I've re-done the connection 4 times now in the hope of making the keyboard work... but nothing. it's a real head-scratcher! You would think that simply inserting the ribbon cable into the slot would be sufficient to make electrical contact, at least for a while; and that the clasps are there just to make sure it doesn't become detached over time.... but it doesn't work no matter how hard it's pushed in!
I don't suppose anyone has a close-up picture of the connection? I want to see if I'm putting it in right. thanks!

Three keys of my keyboard are not working, the cap one, the return key and the space bar, while the virtual keyboard shows to others keys highlighted in orange (^ and `); How to fix it? I writing now with a bluetooth keyboard.

Three keys of my keyboard are not working, the cap one, the return key and the space bar, while the virtual keyboard shows to others keys highlighted in orange (^ and `); How to fix it? I writing now with a bluetooth keyboard.

All new keyboards need Snow Leopard 10.6.8 and above for full functionality.
Rather short-sighted of Apple perhaps, but that seems to be a trend these days.
I'm afraid the only fix is to upgrade to SL. Personaly, I'd take it back and get a refund and seek an older keyboard or a third-party one elsewhere.

Yeah, a portable bluetooth keyboard is the cheapest solution. You can replace the top deck yourself without too much tinkering if you are a little mechanically minded. Most replacement services on the net charge from $150 to replace it. You can buy refurbished top decks from $50 or so. Unfortunately, the keyboard is part of the top case and not an individual part.
One thing to note: If you do decide to buy one and DIY, make sure you get the exact one for your model cos the connectors do vary slightly.

Certain Keys on Keyboard No Longer Work

Hello,
As of a few minutes ago, my standard wired Mac Keyboard appears to be malfunctioning. The Tab and Caps Lock keys no longer work, and certain combinations of keys, such as alt-apple-esc, to bring up the force quit menu is no longer working either. I tried unplugging the keyboard and reconnecting it, I restarted, and I'm still having the same problem - it came out of nowhere.
Are peripherals like the keyboard and mouse covered under my Applecare warranty?
Thanks,
Lonny

Your keyboard and mouse should be covered, but before you give up on the keyboard, get hold of some compressed air and clean it. You can also turn the keyboard over and give it a sharp smack to see if anything is lodged under those keys.
Let us know how you make out,
Miriam

Dead keys in keyboard no longer working

I use "us-acentos" keymap and since 2014-09-24 upgrade the dead keys are no longer working: typing apostrophe followed by "e" should print "é" but instead it just prints the apostrophe.
This under X both in bash and in a graphical editor such as leafpad, geany, netbeans. In a non-X session the dead keys do not work either, an apostrophe followed by "e" will just display a space.
Would anyone have any suggestion as to why this happened and how to correct it? Thank you.

Follow-up:
1) I could restore the keyboard in X with this command:
$ localectl set-x11-keymap us pc104 alt-intl
which creates /etc/X11/xorg.conf.d/00-keyboard.conf:
Section "InputClass"
Identifier "system-keyboard"
MatchIsKeyboard "on"
Option "XkbLayout" "us"
Option "XkbModel" "pc105"
Option "XkbVariant" "intl"
Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection
another option that worked was to rename /etc/X11/xorg.conf.d/10-evdev.conf.pacsave to /etc/X11/xorg.conf.d/10-evdev.conf, which also contained the "XkbLayout" and "XkbVariant" lines under "InputClass" (the original file had been renamed to .pacsave in February 2013). See wiki:
https://wiki.archlinux.org/index.php/Ke … on_in_Xorg
The output from localectl status now reads:
System Locale: LANG=fr_CA.UTF-8
VC Keymap: us-acentos
X11 Layout: us
X11 Model: pc105
X11 Variant: intl
X11 Options: terminate:ctrl_alt_bksp
So it seems that the result of an earlier upgrade was to "unset" the keyboard for X (compare with output from localectl status in original post). Why?
2) the keyboard in console (out of X) is still not working. If I try to set it to "us-alt-intl" in /etc/vconsole.conf, it works as "us" should (no dead keys); it I use "us-acentos" some keys do not work. locale-ctl shows that "us-acentos" does exist (but not "us-alt-intl").
Mystery.

Yoga 3 Pro - Certain Keys Missing from Keyboard. How to virtually use them?

Hi.
I have bought this for about a week and was not happy about the combination of "Home" and "End" keys since I use them a lot. In using VMWare I noticed there is no "Insert" key on the keyboard at all, thus I cannot use the Ctrl+Alt+Insert functionality in my virtual machines. Today, a random combination of keys was pressed on the keyboard and the "Scroll Lock" was enabled, and guess what: There is no scroll lock in the Yoga 3 Pro! Now I have no idea how to disable this again and non of the forums or manuals have addressed this.
(Lenovo design team has made is specifically hard for users. Not only the keyboard layout and certain keys are removed, but even I cannot find a spare chargin cable for my officec. They have changed everything - even Yoga 2 Pro charging cable is not compatible - and yet not available in the market. Not a very smart strategy )
Solved!
Go to Solution.

Welcome to the forum!
I'm sorry to hear about your problem. I had to really take a look at my own Y3P to realize there is no Insert key, I guess I got too used to the touchscreen
To get rid of the Scroll Lock you can press the combination Fn+C.
Alternatively you can also go to the Control Panel, then "Easy of Access Center" and start the On-Screen Keyboard, you can disable the Scroll lock from there too.
