Dead keys on laptop keyboard

I have an HP DV9700T laptop. Is there a tech that reads this forum?
My (9 O L . ) buttons are dead on my laptop.
I ordered a new one & installed it. I still have the same problem.
A friend told me it may be a component (chip, diode, or resistor) on the MB that died.
There must be a tech that knows what controls these keys.
Any help, Please??
Thanks.

Yes there is a keyboard controller on the motherboard of all x86 computers going back to the DOS days. It can go bad. Make sure you have the keyboard ribbon cable inserted in the ziff connector all the way. Clean off the ribbon cable with rubbing alcohol. But if you installed a new keyboard and the exact same row of keys is bad as on the old keyboard it is likely the keyboard controller, which will require a new motherboard to fix. Sorry.

Dead keys on virtual keyboard

My virtual keypad no long allows the use of the "0" key and the "P" key. Both are on the right side of my I-Touch. This prevents me from entering my password for my WI-FI, and any E-mail. All the other key work fine. This morning I downloaded the new I-touch/phone 2.0 firmware today and 2 new apps. I don't know if this is the cause or it the key have been dead for a while, as I have not used the keypad in several months. I have tried doing a total re-set of all setting bring everything back to factory specs. I still have the two dead keys.
Any idea what happened? or should I just go to Apple repair directly?

hi,
i have a NEW ipod touch, still with 1.x version software, and having the same problem. Also the backspace key doesn't function. Should I take this thing back, or can I somehow calibrate the screen?

Stuck key on Laptop Keyboard

I, like a fool, left my laptop open on my bed and I believe my dog stepped on te keyboard, or someting weighty was put ontop of it. Tis isnt a big problem except now my "H" key will only type if i push down rater firmly.
My question is, how can I minimize the damage until i can get to a genius bar? Also, will tis be fixable in a short period of time? I move back to college in two weeks and will need a fully functional keyboard by then.
Tanks!

Is it under any sort of warranty coverage (i.e., AppleCare)? If it is, take as-is to the Store and let them handle it, unless you want to pay for the repair.
If not, [here's a DIY manual on keyboard take-apart|http://www.powerbookmedic.com/Manuals/Apple-Key-Replacement.pdf] that you can follow. If you should break off a keycap, [they also have replacements available|http://www.powerbookmedic.com/Keyboards--Keys-p-1-c-440.html].

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.

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows). The key behaves the same for the laptop keyboard and for an external Apple keyboard? This just started in last week after 6 months of use

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows).
The left shift key behaves the same on the laptop keyboard and on an external Apple keyboard.
This just started in last week after 6 months of use. The right shift key and other keys on the keyboard all appear to work correctly.
Suggestions greatly appreciated.

I have a solution to this issue now after a discussion with Apple Support. Some where in the last few weeks, there was a change in the key that would do a Show Desktop under the Mission Control settings in the System Preferences. Even though the key sequence that was shown for the Show Desktop setting did not include the Left SHift key, by changing this first to having no key sequence and applying that and then changing it back to the F11 key, the Left SHift key issue that I was having has cleared up.
A second issue that was uncovered was that the SSD had some issues (uncovered when I ran Disk Utility using the Repair Disk key). I had to restart and use the Disk Utility through the Command R sequence to get to the stand alone Disk Utility. The SSD appears to be running better as a result as well.
Hope that this is of use to someone else in the future.

Dead Keys on Lenovo W520 built-in keyboard after Windows 7 (64bit) Update

After my Windows 7 update, I have several dead keys. Left Alt, Up Arrow, Print Screen, F5, F6, and the ThinkVantage Keys are all dead. Orginally I thought it was just Windows, but after booting into my Linux OS, I run into the same issues. I have tried reflashing my bios, but that did not fix the problem. Can anyone help?
Hardware: Lenovo W520 (Referbished)
OS: Windows 7 (64bit), Debian Linux (64bit)
Age: 2 months after refurbished
Update 1: Chrome and Firefox would crash if I tried to download something. Did a system restore which fixed the problems with that, but there are still dead keys. I am now downloading a bootable cd from Lenovo. If that fails, I will attempt to reflash one last time before I send this thing to get fixed by the pros.
Update 2: Just remember, why would the lights in the keyboard stop working? They keys still work, but the mike key and the caps key are not lighting up their LEDs when I'm using them.

How to recognise what type of keys are used in the laptop keyboard reading its bottom description?

How to recognise the type of keys (regarding hinges, clips etc.) used in the HP laptop keyboard reading just its bottom description like:

dfe p/n: 9j.n0y82.p01

Many thanks.

Could you please give me the exact model number of your notebook?
You can use the following document if you need assistance in finding it.
How Do I Find My Model Number or Product Number?
And actually I would recommend contacting HP phone support if you are needing to order the keyboard or replacement keys.

[Solved] BEPO keyboard and dead keys

Hello!
So, I'm using a French BEPO keyboard, and it works pretty well, till today.
Indeed, today, I wanted to write a greek letter, µ, but I couldn't. This letter is mapped to Alt-Gr+g.
However, when loading the bepo in the console, it's working well (in a TTY). This only affects QT or GTK applications so far (X).
This is the only one not working: my other dead keys just works like a charm (-> ´+i=í…)
My final purpose is to be able to type any simple greek letter as explained here (http://bepo.fr/wiki/Lettre_grecque_sous_Linux). But I need the mu lettre to work first…
I've tried GTK_IM_MODULE=xim, but then my normal deadkeys don't work anymore nor this alt-gr+g.
By default, I use:
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
I also found out that alt-gr+/(L) is not working as a dead key (in order to type ø for example). (http://bepo.fr/wiki/Barre_inscrite)
I should, lastly, say that I use a typematrix keyboard which is build with BEPO on it.

Hi,
I aslo use the BÉPO layout.
The Alt-Gr + G key changed in xorg with the last update of the xkeyboard-config package (happened on June 02 for me): this combination was the 'μ' greek letter, now it is the 'dead_greek' dead character. It is now what it should be so that is fine.
To type the 'μ' letter, you now type Alt-Gr+G, followed by M.
Note that this dead key works for me only if I use the xim input method. With other input method, some dead keys work, some others don't.
I don't use some variables to set the input method, I use dconf-editor (package dconf),
I set the key org/gnome/desktop/interface/gtk-im-module to xim (you don't have to restart for this change to take effect).
When I was trying to configure greek letters before the xkeyboard-config update, I also found out that when I have a ~/.Xcompose file, it kills all the dead keys of my layout, I don't know if this is a bug or if I'm doing something wrong. Try to remove yours.

[SOLVED] Vi and international keyboards dead keys

Hello all,
I'm learning Vi from the excellent documentation by the author himself and Mary Ann Horton at FreeBSD Documentation. However I'm facing a wall that I can't seem to get around.
Under the portuguese keyboard layout as defined by pt-latin1, the following diacritics are dead-keys:
~ (tilde)
^ (circumflex) (above the tilde, requires also the use of the SHIFT key)
` (gave accent, aka back tick) (above acute accent, requires the use of the SHIFT key)
Because they are dead keys, these diacritics aren't compatible with Vi command mode and certain CTRL combinations. They are however very useful. How can I handle this problem in Vi without remmaping these symbols to different keys (it is very important I don't remap them)? Is there a way to temporarily disable dead-keys functionality and have them function as regular one-hit keys?
My search for pt keymaps without dead keys produced 0 results. So, I don't think that is an option.

Well, I took a closer look at man keymaps and found a way to deal with this; I can create single modifier definitions and load them with loadkeys.
So, if I look at dumpkeys I may find the following two lines
keycode 27 = dead_acute dead_grave apostrophe
keycode 43 = dead_tilde dead_circumflex asciitilde Control_backslash
I now know the keycodes. So I can create a new file (say, pt-latin1-undead), and write this this:
plain keycode 27 = acute
shift keycode 27 = grave
plain keycode 43 = asciitilde
shift keycode 43 = circumflex
Then all I need to do is load it with:
sudo loadkeys pt-latin1-undead
This will load it on top of my current keymap, replacing only those modifiers I defined and leaving the rest intact. When I'm done and want to get back to dead_keys mode, I simply load pt-latin1 again. Tested it already and works flawlessly!
The only disadvantage I can see is that loadkeys requires root access.
Note: The actual code for circumflex is 'asciicircum'. I didn't know this and my first try with 'asciicircumflex' was giving me a syntax error on loadkeys. So I just tried 'circumflex' and it worked. Seems to be a synonym.
Flagging as SOLVED.

My 3 apple products, an imac, a macbook air and a macbook lost their contact with their external hard disks. They were LaCie make. And every time I turn my laptops, I find the positions of the keys on their keyboards changed. Why is Apple silent?

After the latest apple IOS upgrade my 3 apple products, an imac, a macbook air and a macbook, lost their contact with their external hard disks. They were LaCie make. And every time I turn my laptops, I find the positions of the keys on their keyboards changed. Why is Apple silent? There are so many people complaining about this issue and expecting Apple to correct this issue that they have created.

Probably because it's not an Apple issue. I have Lacie EHD's connected to my MBAir and iMac, all work perfectly on Mavericks. In addition I don't have any keyboard issues on any of my Apple products. BTW IOS is only for IOS devices such as iPads, iPods and iPhones, Macs use OS X. The two OS's are seperate products designed to run on seperate products.

GTK3 applications treat all keystrokes as dead keys

I noticed this after re-installing my system after a major hardware upgrade yesterday. In any gtk3 application (evince, nautilus, gedit, etc.) any and all keystrokes are treated as dead keys (i.e. hitting the key twice results in the desired character). I have no idea where this may be coming from, but it works fine in google-chrome, urxvt, Skype, texmaker, blender, etc. I have played around with my keyboard settings in xorg.conf, but since it works fine in all my other programs, it seems to be a problem elsewhere. I also set my keyboard layout in gnome-control-center. Possibly related: Nautilus refuses to change icon themes. Also, repeatedly clicking with the mouse (going through a menu/settings, for example) causes no mouse clicks to be registered at all.
Any ideas would be appreciated!

So far I have noticed no change in this behavior. I've moved some settings folders (.gconf, gedit, gnome-session, etc.) but to no avail. My laptop has showed no signs of this problem, and I am stumped as to where else I should look for the problem. Any suggestions/comments would be welcome!

No dead keys in Qt applications

Hallo everyone.
I use KDE 4.7.4-1 (latest stable) and have enabled two keyboard layouts, English US international with dead keys and Greek polytonic. Dead keys work perfectly in Greek in all applications, but not in English in Qt applications. For example, I can press “^" and "o" in Chromium and produce "ô" but if I try that in Kopete the whole sequence will be ignored.
Does anybody know if this is a known bug or a problem with my system?
Thanks in advance.
