Keyboard sticks repeating last key press

Since I bought a new PC I have been having an issue with keyboard input.
Quite regularly the keyboard appears to crash continually repeating the last keyboard press. Removing the USB port and plugging it back in restores normal order.
This does not happen in windows on the same machine. It did not happen using ARCH on my old PC but with the same keyboard. So I suspect something software related to do with the motherboard.
For reference they keyboard is a Microsoft Natural Ergonmic 4000 keyboard.
Motherboard/CPU is Intel Haswell based.
Gigabyte Z87-D3HP Intel Z87
Intel Core i5-4670
I was suprised to find no one else with this issue which might mean something but I don't know.
Any help much appreciated. This makes Arch on my new PC basically unusable.

Is the keyboard directly connected to the machine or, e.g. through a usb hub? Did you try switching to another usb port?

HT1338 how do i get voice over say the last key pressed.

A friend is blind. He can hear e-mail but it would begood if he could hear the keyboard keys pressed. Will voice over say the last key pressed.

Last key pressed repeats infinitely

Sometimes while I am typing, one of the keys I type starts repeating itself infinitely (even though I am not pressing the key down). This can happen in any application and with any key. It also sometimes happens when I use hotkeys. For example, when I use Command-b to bold highlighted text, occasionally the command repeats infinitely and the highlighted text blinks bold-regular-bold-regular-etc. The repetition does not stop until I press another key on the keyboard, and then I have to go back and delete all of the repeated letters which have appeared on the screen (or undo whatever havoc a repeated hotkey command has wrought). What is causing this problem and how can I fix it?
Thanks!

Check the keyboard settings in System Preference. Your keyboard may have dirt or crumbs stuck underneath the keyboard. A can of compressed air should blow it all out or run a vacuum hose across the keys to suck it out.
If computer is still under warranty, contact Apple if the above does not resolve the issue.
Out of warranty, Do-It-Yourself Laptop Repair will show & tell you how to clean your keyboard.

Non-repeating multiple key press issues

My g/f has a G4 Titanium Onyx and seemingly randomly, the keyboard has started acting up.
The bottom row of keys works, but anything above it gives out multiple characters on a single keypress. These are non-repetative. For example hitting 'l' doesn't cause 'llll' but '963.'
The same keypress gives the same array of incorrect characters every time, but they don't seem to follow a pattern, one key even seems to work like the volume key.
To the best of my knowledge it hasn't been dropped, had anything spilt on it, of been damaged in anyway since the last time it was working well.
Any ideas as to what's causing this? The missus is most upset.

Hi, Sam. Does "g/f" = "grandfather"?
The behavior you describe is a new one on me.
First check to make sure the Num Lock key isn't depressed (the light beside it should be lit if it is). With Num Lock depressed, the m, slash, j, k, l, semicolon, u, i, o, p, 7, 8, 9, and zero keys should produce numeric-keypad characters, and most of the others should produce nothing. That's not what you're seeing, but I suppose the Num Lock key might, if it's depressed, be modifying the way some other error or malfunction shows up. If it isn't depressed, try connecting an external USB keyboard and see whether that behaves the same way. If the external Kb works properly, the built-in keyboard is bad or not securely connected to the logic board. Release the keyboard latches and tip it back onto the palm rests, then disconnect and reconnect its ribbon cable connector. If there's no improvement, replace the keyboard or have Gramps use the external KB instead.
If the problem occurs with the external KB too, boot to your OS install CD and try to set up and name a new admin user account. If you find that you can't do that because you can't type normally with either KB, even when booted to the CD, you have some hardware problem that's not in the KBs, and it may be time to have a technician look at the PB.

Multiple key press's with Bluetooth Keyboard

I'm ready to update my mac to a new G5 imac and fancy getting the wireless bluetooth keyboard and mouse with it.
I have one question, has anyone experienced problems when holding down multiple keys on the keyboard and moving the mouse all at once (Using illustrator)?
In my office I have the misfortune of having to use a PC, I have had a number of wireless keyboard and mouse combos, all of them when using Illustrator and photoshop can not handle multiple key press's and mouse movement.
ie if I'm duplicating an object by dragging a copy of it across the screen, on the PC it will work but it always "releases" after a couple of seconds and drops the copy in the where I don't want it which gets very frustrating (this only happens with wireless).
As I do a lot of work at home, I hoping this wont be the case with the mac's bluetooth K & M.
thanks
Russell

The shift key works just fine on my Bluetooth keyboard. So I would imagine this is an issue with your keyboard.

Repeat last command with enter key in dbx

I am using dbx 7.7 on Solaris 10 (Sun Studio 12.1). Is it possible to configure dbx so that pressing the <enter> key will always repeat the previos command? for instance, if i do one "next" command, i want consequent <enter> key-presses to do "next", until i explicitly execute a different command.
Thanks,
Yael

Hello Jean,
Thanks for this advice, i started working with dbxtool and it's very nice.
2 questions:
1. The Function keys (F7, F8, etc.) don't work, any idea what could be the problem?There is a bug in the dbx cmdio window where it ignores F-key. It doesn't even have
a decent context menu. You should be able to get F7 etc working by moving the
focus elsewhere, like the editor window.
2. In the default .dbxrc file there's a line "button ignore step up" to "add `step up' button to GUI", but no button was added. Is there anything else i should do to make this work?
These are really old. (we should remove them from the default .dbxrc!)
The current way to add a button is via Debug->NewDbxButton
Thanks,

What are the key presses like on the Enhanced Performance keyboard?

Hi guys,
I've been thinking about buying this keyboard:
http://shop.lenovo.com/SEUILibrary/controller/e/gbweb/LenovoPortal/en_GB/catalog.workflow:item.detai...
I was wondering how the key presses feel? I'm quite particular about it. I like the press to have a definite 'soft click' (like a cross between a microswitch and a diaphragm). A lot of keys these days are like pressing a spring with no tactile response as to when a key press has actually been registered if that makes any sense.
Can anyone with this keyboard describe how the keys are to press? I can't find and videos or any real life examples to test.
Thanks,
Leo

if you are looking for tactility in a keyboard, than this keyboard is not the best. Maybe you should get a Filco keyboard instead.
Microsoft and Dell's keyboard (the one with oversized spacebar) are both slightly better than these Lenovo keyboard. Alternatively get the Space Saver II keyboard.

No long key press on bluetooth keyboard?

I'm wondering if this is a limitation of the actual keyboard itself, iOS or even the app I'm using. Where if you press a key on the keyboard and hold it, the iPad sends that key over and over until release. Unlike the normal behavior of the key action 'OnDown' remaining active it simply resends the key.
I am using the ZaggMate and Splashtop to remote into my computer a play a game. For this game, in order to move, you need to use the arrow keys. Since holding the key fires multiple 'OnDown' and 'OnUp' events, the movement is not fluid, more like stop, go/stop, go.
Is there a way to work around this/where is this key press event actually getting mixed up?

We had a couple 911 calls our first couple days with our uc540. What came up with was that our old phone system buttons had a different feel. With these cisco phones, if you press the button all the way down in a quick press, the nunbers never double for us. You can hold down forever and never get a duplicate. But if you press slowly or don't press the button all the way, I can get double numbers when pressing. I think that there's a point in the actuation that the button can float between on and off and that can give you double numbers (I think in the gaming community that this is called "spamming" the button). Our old system took less pressure to press the button all the way down and as soon as we told everyone to press harder we haven't had a accidental 911.
If you push a button half way down and shake it left to right you can see a good example of how to spam the button. Yeah, that isn't how a person dials, but the first few days we got double-numbers just with people making calls. We have a few spa and a few 7900 series and we had issues on both but more on the spa phones.
One specific person had the most trouble and this person doesn't have the most stable hands... She wasn't calling 911, but she just couldn't dial the right number because they'd get an unintentional double digit in the middle of their dialing. She really has to press every number deliberately to make calls--I wish I had a better solution for her because it makes here feel dumb.

Simultaneous key press on the keyboard GX600

hello guys,
i bought a MSI GX-600 thinking that it could accommodate my gaming needs however i found out that it cannot allow more than 2 simultaneous key presses on the keyboard. its supposed to be a gaming laptop right? i cannot play keyboard bashing games with this unless i use a gamepad or an external keyboard. have you experienced this on your laptop?
do you think an update of the bios will do the trick?
try this link to test if your keyboard can handle more than 2 keypress at the same time:

The problem comes from the way in which the signal for the pressed keys moves from your keyboard to your computer. The signal is only 8-bit, and there are limits to how the signal can be changed to represent more than one key being pressed in combination.
Long story short, the guys who designed the origional keyboards made a descision to support all two key combinations, and then selected as many three key combinations as they could support with the hardware. This meant that some combinations had to be left out, and they had to make a descision about which ones were more important.
It just happens to be that they chose not to support three key combinations which involve the up arrow key. I do not think there is any solution to this problem…
If you're playing games, why not just remap the keys in the game's settings?

How can we trape the Keys Pressed on the Keyboard and do action depending on the keys

I want to know how we can capture the keys pressed on the keyboard by the user and do necessary action depending on the key pressed by the user....
For example.... If user press Alt+q the form should go in the Enter Query Mode.
Can anyone tell me how i can do this in Form 6i....
Please Help me out from this problem...
Thanks in Advance
Shan

Can somebody point me to what I need to use to
intercept all the 'keys' for an application.
At the moment I have set Focus to parts of the
application when the Mouse is over it, and then get
the Keys with a KeyListener.
Is there a way to get the keys, as long as the Java
app is active.
- Its an image display program, and I want to use keys
for - next image , zooom etc etc.
If soemone could just point me to the right part of
the API to look in?java.awt.Toolkit.addAWTEventListener()
then use the mask defined in AWTEvent.KEY_EVENT_MASK to listen to all the events.

TS1277 HI. I have followed all the appropriate steps above and when I try to enter my 'Password' when asked, my keyboard doesn't work. No key press can be activated at all when trying to enter my password in 'Terminal. And I am in the 'Administrator' user

HI.
I am having trouble authorising my Mac Air to my Itunes account. I found a discussion explaining how to go go into 'Terminal', then adding a command. I have followed all those appropriate steps and when I try to enter my 'Password' when asked, my keyboard doesn't work. No key press can be activated at all when trying to enter my password in 'Terminal. And I am in the 'Administrator' user. Can anybody offer any suggestions?? ta

Does the command that you're trying to enter in Terminal begin with the word 'sudo'?
If so, your keyboard is working fine. When you type your password after a sudo command, nothing is echoed to the screen for security reasons (not even the * that are normally registered in other user interfaces). However, the program is registering what you type.
Just type your password and press 'return' and the command will be executed (so long as you type it correctly; if you don't, you'll get an error message).

I cant use the X key on my imac wired keyboard, the key viewer shows the two commands keys pressed when i hit x and the caps lock light is always on....thank you

I cant use the X key on my imac wired keyboard, the key viewer shows the two commands keys pressed when i hit x and the caps lock light is always on....not really sure what happened, but i didnt do anything different from my daily stuff
just an update....when i hit the right command key it respond normal (cmd v cmd c...etc) but when i hit the left command key it shows the x and two commands pressed as well as it delete what i'm working on i.e like backspace but takes out everything at once
thank you

Hi Moe,
Sounds mostly likje a bad KB, do you have another to test with?
Or...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Keyboard character repeat delay

I have JDK 5 Update 4. Does anybody have an idea on how to access the keyboard character repeat delay and repeat rate?
I want to shorten the delay and possibly the repeat rate. Is there a way to get the keyboard and it's properties somehow?

lol I delt with the same issue while making a galaxian clone.
I wanted to completely get rid of the delay and make the repeat rate equal to as fast as java could execute it (meaning assume that it repeats every single time the paint() method gets executed).
for instance, if I want the ship to move left and keep moving left (meaning no delay and incredibly fast repeat rate), I did this:
inside my KeyListener I have boolean Left. inside keyPressed, I have a switch statement that, if the left key is pressed, sets Left to true. inside my paint() method, I check to see if myKeyListener.Left == true. if it does, I move my ship to the left. inside of keyReleased I have a switch that sets Left to false. therefore, there is no delay at all between the key being pressed and the ship moving, and so long as you hold the key down, the ship keeps moving over at a constant rate that has absolutely nothing to do with the repeat rate of the KeyListener. hacking into the OS is way unnecessary.
if you want there to be a significant delay (the way my firing of bullets does), then do this
//inside the constructor of your GUI, set long milliSec to System.currentTimeMillis().
if (MyKeyListener.SpaceBarIsPressed == true && System.currentTimeMillis() >= 500+milliSec)
//the code necessary to shoot a bullet
milliSec = System.currentTimeMillis()
}that will make it so the next bullet cannot be fired until its been at least 500 milliseconds since the last bullet was fired. giving you a constant repeat rate with no start delay.
