Centro Keyboard Lock / Failure

Hello,
I have a Palm Centro (AT&T) that I have been using for about 2 years now. The other day, the keypad just sporadically stopped responding after more than one input (for example, I can hit any of the keys once and they will respond, but not again after being hit once). In addition, the large buttons (phone, applications, calendar, messages), green call button, and navigation buttons will not respond at all. However, the power button and center key will respond in order to bring the phone out of the power-save mode, but not respond in any other circumstance (aka cannot turn the 'phone' off). The touchscreen still works though.
I've performed a soft reset, but I cannot perform a hard reset as the phone does not seem to recognize me releasing the power key at the second palm logo (it freezes though if I had been holding the key down, again, it seems to recognize the key press only once).
Does anyone have any ideas as to what I could do to remedy this? I'd like to make sure it's not something I could solve with a reset (if I could get one to work) or some other software fix.
Post relates to: Centro (AT&T)

Hello and thank you for using the Palm Help Forums!
If the device will let you, perform a warm reset. It's similar to the hard reset except you hold the Up button on the 5 way navigator. This is going to put the device into a safe mode and just load the applications necessary for the device to run. See if the buttons are working then. If so, soft reset the device and see if the problem still occurs. If the problem still occurs in a warm reset I recommend replacement.
If it does work (in warm reset) and you soft reset the device then the problem occurs again, then I would warm reset the device and while in warm reset perform a hard reset.
I hope these tips help,
-Pat

Keyboard+XOrg failure?

I was just reading the Con Kolivas thread, and this announcement on the LKML.
He references a Keyboard+XOrg failure which is 'well-known', any information about that? I've been using custom kernels, and once in a while (normally with a <Super>equal which I have binded to my 'increase volume' with mpd) I manage to have my system hardlock, only recoverable (and sometimes not even) with the magic SysRQ. Didn't think much of it, since it happens quite rarely and I compile my kernels with various options all the time.
So, anyone has experienced this or read about it? I'm obviously not on the LKML (so many emails...)

You're not dumb — many others have made the same trivial mistake and been completely unaware of the Num Lock function, including me a while back.

}The second program will lead to keyboard-focus-lost in RHEL 3/4 and red flag 4/5, J2SE 5, not in J2SE 6.
And I also tried java demo program "SwingSet2" in red flag 5, met keyboard-lock too.
I guess it should be some kind of incompatibleness of J2SE with some Linux platform. Isn't it?
Please help, thanks.

Hi.

How can I make a "Keyboard Lock" while iTunes is playing?

How can I make a "Keyboard Lock" while iTunes or other apps are playing? They should work/play on, screen should still be on, only keyboard is (maybe Password-) locked.
Thanx in adv, tttimo

You will need to restart Pages but should then see it next to your Menu item.

Keyboard lock and unlock for 8330

I need a way to lock and unlock the keyboard. I have searched a number of websites for an answer to my dilema and it seems several methods are mentioned but none work for me. I need to lock the keyboard when phone is in my pocket. Many thanks to anyone who can help.

Well, according to your device manual, this is the procedure:
Lock the keyboard
If you do not set a BlackBerry® device password, you can lock your keyboard to avoid making calls and pressing keys accidentally.
On the Home screen or in the application list, click Keyboard Lock.
To unlock the keyboard, press the asterisk (*) key and the Send key.
You can look further into your manual here:

BPS keyboard lock issues

Hi all,
I've various layouts for forecasting.I execute the planning folder to enter forecasting values.
My problem is -
Sometimes when I log into the screen(after executing the plng folder) for the first time, the keyboard locks and you have to click on the check button to enable it. Can this be solved?
Any help will be appreciated.
Thanks in advance.
Isha

Hi,
This has happen to me very often...if you execute planning folders with excel as the front end.
The keyboard is not locked but even if a cell is selected and you enter digits...they just don't appear. Surprisingly, digits entered become part of the excel macros. When you press refresh the macro debugger gets started as the code (with the digits just added) is wrong. It's a nightmare.
This does not happen in all our computers. If you select a cell by double clicking over it...the system works fine.
Yes, strange but true.

Keyboard locked and frozen

hi.
since i installed arch64 on my new machine, my keyboard randomly froze and i can't type anything with it anymore. I had everytime to log out from X. and then i can use it again.
when it is locked even typing a key like capslock or numlock do not change the led on the keyboard
so though i first thought it was an hardware problem with the usb dell keyboard, i think now it has to do with kde or X.
anyone ?
i have changed the line
Option "XkbModel" "dell"
in my xorg.conf to:
Option "XkbModel" "pc105"
but i still got that problem.
it seems to happen when i want to type too fast and type 2 or 3 keys at the same time with a ctrl or alt or altgr or win key. don't know

Am using:
64-bit AMD
32-bit Arch kernel and other packages
nVidia
xorg
kde
On-board video is: nVidia Corporation: GeForce 6100 nForce 405
All software (kernel, drivers, etc.) are up to date. Yet, another lockup happened about 30 minutes ago.
When the keyboard locks up, it feels like it's locked up, but has not. If I hold down any character long enough, it comes through. Same goes for modifier keys. So, to do Shift-A, have to hold down the Shift key for about two seconds, then hold down the A key for two seconds. Typing a password is excruciating -- OK, really, impossible.
Since the mouse consistently works, I can kill applications and then K->Log Out...->End Session OR start a new session. When the X login appears, all is well.
If I start a new session, the keyboard works just fine in the new session. If I return to the original session (Ctrl-Alt-F7), the keyboard is still locked up in that session. Go figure.
Seems like all reports about this mention keyboard locking up. Can anyone try this next time? Hold a key down and see if in a few seconds it comes through. Would be interesting to see how many cases there re of complete lock up vs just a super slow keyboard response. (And who knows. This info. might even help someone find the root cause.)
EDIT: To try to fix this problem have tried various mouse and keyboard brands. Have tried unplugging and plugging back in the keyboard and mouse several times (right after a lock up). Have also tried to avoid various applications -- just in case it's related to user space interaction (getting desperate, I guess). The problem persists. It's very random, too.

Video/Audio Lock Failure Error Message

Every time I try to watch a show or a movie On Demand the screen goes black. Then a few moments later I receive an error message stating: " Video/Audio Lock Failure." Does anybody know how to fix this?

I just upgraded to FCEHD 3.0 from FCE 1.01. I was in the middle of capturing clips on a large project when I made the move (today). I got this same message and just found this answer -- thank you very much.
Should I go back and recapture all the clips that I did in FCE? I did not get the error message, but I have no idea what the settings were, either.
BTW: I am using a Sony PDX-10. Why would a professional camera be set up in 32K audio?

Keyboard lock on word lookup

It seems upon the new update, whenever I lookup a word (e.g. on Pages) the keyboard locks and I must restart the computer in order to restore keyboard functionality. Is this occurring for everybody on the latest update (10.10.3)? It is extremely bothersome and I hope it gets resolved ASAP!

I have also been running into this
since the last upgrade on OS X Yosemite. After eight clicking and attempting a word lookup the lookup returns blank and they keyboard become unresponsive. This will continue until the Mac is rebooted. I am running a 13mbr 2014.

Keyboard Lock help

It's a little thing... however... I recently got a Curve 8900, and I can only lock/unlock it by pressing the top button. On my brother's Curve... he's able to lock/unlock by pressing A+Send. For the life of me I can't figure out how to get mine to do the same thing. I went to the "Tips and Tricks" section for my phone, and it actually says that the A+Send option is the standard way to lock/unlock. Now I'm confused.... Please help.

Yes, it is.
You can set a password on the device, and the lock icon will return.
Or, you can use the K key to press to lock the device if your Call Log > Options > Dial for Homescreen > set to no.
