KEY PRESS ISSUES

I own a Pre Plus on Verizon. I have read the numerous posts describing issues with keyboard key press difficulties. What I haven't seen, is any resolution to the problem. Personally, The keyboard size is OK. The unreliable key press issues are driving me nuts. The worst key on my Pre+ is the "e" key and some others, mostly on the top row of keys. I first press, nothing, press again, maybe nothing or multiple entries of "e", The "y" is second worst. Same issues. Is ANYBODY doing anything to resolve this problem?
Post relates to: Pre Plus p101vzw (Verizon)
This question was solved.
View Solution.

The last software update 1.4.11 addressed this issue on the Verizon Palm Pre Plus. If you are on earlier software version you need to update your device to the latest SW version. If you are on the latest SW version you may have a hardware problem with the device. You should go to Device Info from your launcher, tap the drop-down menu, choose Tests, then Interactive Tests, then test your keypad for problems. If this test fails then you should get a replacement device from Verizon.

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.

What is the question?
doSendTypeStatus() function getting called automatically ,i.e. with out being pressed any of the key on key board .No, it is getting called whenever a key is pressed in the text area. It can be any key, but a key must be pressed. If you claim not to be pressing any keys, please print out the event.
// wrong:
if(e.getKeyChar()==KeyEvent.VK_ENTER) {
// right:
if(e.getKeyCode()==KeyEvent.VK_ENTER) {You should compare codes with codes, not chars
Lastly you might want to use a document listener instead, so you also get notified when the user pastes something in the text area.

Key shortcut, issue, typing something in editing code and changing language going directly to snippets.

Key shortcut, issue, typing something in editing code and changing language going directly to snippets.
So the problem is that I have to click in the editing code again to write in different language, which it didn't happened before.
Just in case of shortcut keys collision I completly removed the shortcut of snippets from shift+F9, nothing changed. I really can't understand why when I press Alt+Shift to change language it goes straight to the snippets.
If anyone can help would save me from nervous breakdown!
Thanks,

Since this appears to be a "just started happening" issue, have you tried clearing the program cache?
Deleting a corrupted cache file
That tends to catch a lot of weird behaviors and straighten them out.

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.

Serious Keyboard Key Mapping Issue

Hi there everyone...
Yesterday evening, while i was watching a movie on my Macbook, i accidentally pressed the command button, and all of a sudden the movie stopped playing.
After some research on the internet, I activated the keyboard palette, and found out that several keys had issues
1. The left command button behaved as if i was pressing command + . (period key)
2. The right command button behaved like command + up arrow key
3. The up arrow key like issue 2 above
4. The period key like issue 1 above
p.s. the up arrow and period keys arent working at all, they just behave as i explained above
Since it had to do with a modifier key, i tried to change the modifier key settings, but even though i tried accessing the modifier key settings through preferences, no pop-up window opened and no change could be made.
Even though i tried a PRAM zapping, nothing happened because as i understand it, the system doesnt recognise the shortcut, since together with command,option,p,r, the period key is seen pressed as well.
If anyone can help please do!
Thanks for your time everyone,

So I booted from the install disk.... Didnt now what exactly to do, so i use the terminal to see if the problem with the keys persisted... And unfortunately it did.... Didnt know what to do next so i quit and booted again...
But i restarted my macbook, only to boot into hardware test mode, to see if the problem really is on hardware side.
I am running an extended test, but poking around a bit, i noticed that the up arrow key worked fine...
Waiting now to see the results from the test, which i will post after it's finished.

Simultaneous ASDW key press undetected

Hi guys, I'm currently developing a game that uses ASDW buttons for its movement system
During one of my testing session, i realized that if i press 2 buttons simultaneously, (ex: A and S), both events would be dispatched one after the other (just like what i assume they would do)
But if i press 3 buttons simultaneously, (ex: A, S and D), the last keypress (D) will go undetected
Only after i release one of the keys (either A or S) will the last keypress be detected
From what i read here ==> http://blog.nobien.net/2008/05/12/more-than-two-simultaneous-key-presses-and-keyboardevent key_down-woes/
It is said that the problem might had been caused by a hardware issue
From what i read at wikipedia http://en.wikipedia.org/wiki/Keyboard_%28computing%29
[quote]
Some low-quality keyboards suffer problems with rollover (that is, when multiple keys are pressed in quick succession); some types of keyboard circuitry will register a maximum number of keys at one time. This is undesirable for games (designed for multiple keypresses, e.g. casting a spell while holding down keys to run) and undesirable for extremely fast typing (hitting new keys before the fingers can release previous keys). A common side effect of this shortcoming is called "phantom key blocking": on some keyboards, pressing three keys simultaneously sometimes resulted in a 4th keypress being registered.
Modern keyboards prevent this from happening by blocking the 3rd key in certain key combinations, but while this prevents phantom input, it also means that when two keys are depressed simultaneously, many of the other keys on the keyboard will not respond until one of the two depressed keys is lifted. With better keyboards designs, this seldom happens in office programs, but it remains a problem in games even on expensive keyboards, due to wildly different and/or configurable key/command layouts in different games.

Question
- What causes this problem is it a hardware issue or a language/flash player problem?
Because i might be wrong, but i think i've played several non-flash games before that possess the ability to address multiple keypress at the same time
- Can this problem be fixed?
Code
package
        import flash.display.Sprite;
        import flash.events.KeyboardEvent;
        public class Keyboard extends Sprite
                 public function Keyboard()
                        this.stage.addEventListener("keyDown", showKey);
                public function showKey(event:KeyboardEvent)
                        trace(event.keyCode);
Any help regarding the matter is greatly appreciated, thank you in advance~

do you think an update of the bios will do the trick?
No, no, no, it won't, so please don't try it!

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?

IdeaPad U330 key presses registered twice

I bought a U330 about a month ago, and I'm wondering if anyone else has had trouble with their keyboard. My issue is a bit vague and unpredictable: every now and then when I'm typing a lot, key presses will register twice. This seems to most commonly happen with the 'm' and '-' keys; in fact about one in every five times I type "vim foo bar" at a console I end up producing "vimm foo bar". Every now and again I get repeats with other keys, but it's not predictable.
It is not a software configuration issue like changing the time delay between the input driver accepting a press-and-hold as multiple presses. For fun I tried increasing this value as high as it would go (which gets to be around 500ms) and still no luck. The hardware is clearly reporting two distinct taps when I'm physically making one.
For a while I was convinced that I just needed to get used to this particular keyboard, but I'm convinced this keyboard is finnicky. I'm a solid typist as I work in IT and have spent more than a few years of my life mashing at keyboard; I type quite firmly and quickly so I'm confident this isn't anything I'm doing wrong.
Has anyone else seen this issue?

Try updating the drivers and the BIOS.

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.

Virtual key press of an external usb device

Dear champs,
There is an USB device which has a keypad with 10 keys. During the testing of device, the keys has to be pressed and for every keypress there will be some actions involved.
The idea was to automate the key press without any manual intervention. I hope some hardware will help in achieving the key press action. I mean some DAQ (example) hardware will simulate some signals that will be equivalent to the key press.
Does my query makes sense. Please throw some lights.
Thanks for ur patience.
Mathan

A few years ago, I had a similar issue, which I solved using C. When the key was pressed on the USB device, it sent a keyID number to user32.dll. The program I was communicating with read the keyID and did it's action. As the hardware and software were both bespoke, the software knew what do to with the keyID.
To simulate the USB device I set up a program which would capture events sent to the keyboard function in user32.dll and record the key number. Then to simulate the device, I simply sent the integer number to user32.
I would sugest seeing if you can do a similar thing and read the numerical value for the key being pressed.
Alternately you could see if you are able to access the driver dll while the device is running, and have a look at what data is being passed around, then seeing if you are able to inject your own into it.

Ctrl-F key presses fill up undo buffer

I recently discovered a perplexing issue in Final Cut Pro.
The Ctrl-Fkey transport keys apparently are considered actions
by FCP and hence occupy the undo buffer. Using these keys
to shuttle the timeline will effectively wipe out any important actions
previously stored in the undo buffer and replace them with blank
key presses.
Probably not many people use these keys for that purpose however,
some devices do such as the Bella Professional editor's keyboard.
It has a jog/shuttle wheel built in that is configured to use these
very key presses.
Is there anyone who has noticed this behavior or has been able
to resolve it? Incidentally, to use these keys as FCP designates, one
must turn off Keyboard Navigation in the Keyboard & Mouse pref panel
since they are already assigned by the OS.
Dual processor G5 Mac OS X (10.4.8)

Steve, the ShuttlePro looks like a terrific
controller.
To be honest I don't think the design of the shuttle knob is that great, and I don't end up using it as much as I thought I would. It's nothing like the real edit controller shuttles of yore.
By speed select keys are you referring to the J and L
keys or the Ctrl-Fkey's?
I meant the key combos that set a specific speed. As above, thinking I would use the shuttle more I set them to speeds I would actually use - skipping ones that weren't useful to me. It was a lot of work which I'll go undo now...
It WOULD be great to have slow frame by frame play
(JK and KL) on the shuttle as well but like you've
already said, apparently it is unique to those
particular keys.
As long as you map to the actual J K and L keys from buttons you can press individually, it works. It doesn't work with the ShuttlePro knob simply because they only allow one button press to be programmed for each position.
My problem was that I had mapped the ShuttlePro buttons and their functions to new places on the keyboard. The JK and KL functions seem to only work when you're mapping to those actual keys. So I have J K & L mapped to buttons on the ShuttlePro (their default, actually) and it works great.
What really disappoints me is that FCP doesn't support a range of playback speeds that would allow something approximating shuttle behavior.
Thanks for bringing the Undo problem to our attention!

Backlight key presses not detected, OPTIMUS, wiki didn't help

I am using a Razer Blade 14" with linux-ck kernel (although I have tested in the main kernel and the issue remains).
The keyboard brightness settings keys are not detected by X at all (using xev reports no keycodes when I press them).
However, the driver is getting that information. And in the same type as other function keys (such as sound up/down - which are detected correctly).
I know this because, while investigating the workings of the touchpad, I ran the razer-test script found in:
http://fxchip.net/RazerBlade/
(slightly modified because the device ID is 0x011D in the 14").
It distinguishes normal key presses from Macro Keys. Function keys in this laptop are macro keys. When pressing volume down, I get the following report:
Macro keys: Razer Extra Buttons:
Extra key: FN
04 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Macro keys: 02 ea 00 00
Macro keys: 02 00 00 00
Macro keys: Razer Extra Buttons:
04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
When pressing brightness up/down, I get the following report:
04 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Macro keys: 02 70 00 00
Macro keys: 02 00 00 00
Macro keys: 02 6f 00 00
Macro keys: 02 00 00 00
Macro keys: Razer Extra Buttons:
04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
(note that the last part just signals that I let go of the FN key)
My idea was to try to find the keycodes through xev and then map them manually. However, this was unsuccessful since xev reports no input when I press brightness up/down (while volume up/down works).
This is where I'm lost - the keyboard drivers seems to just be ignoring them.
Any help appreciated . Let me know what I can post if it's of any help!
Cheers,
Rodrigo
EDIT:
My laptop uses optimus hardware, and I'm using the integrated Intel Graphics card.
I have tried all the methods in the wiki but none of them worked:
https://wiki.archlinux.org/index.php/backlight#Overview
https://wiki.archlinux.org/index.php/In … ter_resume.
It's also worth noting that I do have control over the backlight with software - the FN+F8/F9 key bindings are the ones that are just completely ignored by the driver.

Hey. If you aren't using the nvidia graphics card then this works on mine.
Edit the /etc/X11/xorg.conf.d/20-intel.conf by adding

Xorg normally automatically selects the backlight device. On mine it ued acpi_video0 instead of intel_backlight.
Hope that helps!
Thanks, but the challenge is, to get nvidia prop. drivers working.
I think, I tracked the problem down to some backlight issue, probably a firmware issue with the laptop model.
On ubunutu, ideapad backlight modules gets loaded, on arch, it uses the intel-bl. As it stands to reason, backlight settings are too dim when starting X.

Im working on a small program that needs to get the amount of keypresses a user makes over time.

                        countDown(5);
                    else if(time == 5)
                        display.setText("Number of taps: " + taps);
                        //System.out.print("Number of taps" +taps);
        }, 0, 1000);
}But i get errors when i try running it:
"Exception in thread "Timer-1" java.lang.RuntimeException: Uncompilable source code"
It doesnt seem to like me parsing int to string here:
String s = Integer.parseInt(i); Any ideas? or if youve got suggestions on another way to do it it'd be much appreiated.
Thanks!

Yikes, you've got that bit of code backward, there partner.
You use Integer.parseInt to parse a String into an int, not the other way around.
If you want to change an int to a String, do
String s = String.valueOf(i)or you can use the various formatters out there.

2 key pressing at a time?

i am currently making a java application that require 2 key pressing a the same time with KeyPressed(KeyEvent e)but it doesnt seem to work.does any body know how to do it? thanks

This is only supported with the "meta" keys (Control, Shift and Alt). Look at the KeyEvent for the methods to determine which meta key was pressed in combination with the other key.
