Certain keys not responding

Today on my mac book the A,S,U, and Y keys stopped working. Randomly before they all quit the U key would act like it was stuck and start filling up a text box or address bar, even if I hadn't touched the key. The track pad also started acting weird i.e. the pointer would be sluggish. Any ideas?

It sounds like you need a new keyboard/trackpad (which is the "top case" part). If your system is under warranty, take it in for service. If it isn't, the repair isn't extraordinarily hard (See instructions here). You could just try to reseat the cable and see if that fixes things.
Powerbook Medic has some new top cases in stock for USD$149 each.

10.4.11 Policy Key Not Responding

I opened my activity monitor to check on a current process then noticed in red, Policy Key Not Responding. It had 4 hangs as well. I have repaired disk permissions and that is about it. My question is, is there a security problem of some sort when my Policy Key is not responding and secondly how can i fix this. Thanks for the help.

Here is what is listed when I check the info from the process. Its parent process is called Window Server 64. Not sure what any of the below means.

Liquid spill on keyboard. Certain keys not working. Any inexpensive repair? re

Water spill on the keyboard of my Mac Book Air. Now certain keys not functioning. A Mac friend suggested submerging in rice upside down to dry out. Didn't work. Warranty expired. Help!

Yes, the "magic rice trick" doesnt work.
inexpensive repair? No.
Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

6630: Certain Keys Not Working

For some reason, my Nokia 6630 has certain keys not working. Actually, sometimes they work and sometimes they don't. I doubt it's a cover problem, because even when I take it out, the keys still don't work.
The "1", "3", "C", Left, and Up don't work at all, and it's annoying. Some help, please?

The phone is too old and I think it has no FW upgrade in NSU.
I guess this could be a hardware fault. Better if you go to service point.
But before that have you tried a hard reset?*#7370#.
[It will clean up the phone memory, so better back up by PC Suit).

Certain Keys not working - Softwarewise!!

I have a 12" powerbook, german keyboard layout and I have a problem with my "Umlaut U" key and my Arrow-up key. But only in certain applications and also not permanently. Sometimes they work, sometimes not. Its not a hardware problem due to the fact that the keys immediately respond when i switch to another app.
any ideas here?

Certain keys not working envy dv7-7304tx

My keyboard will occasionally lose the ability to register certain keys when pressed. In particular, the top row of number keys will frequently stop working. For instance, at the moment the five, six and dash will not work, and fifteen minutes ago none of the numbers in the top row would. The right-side number pad also will occasionally not work. After a short time everything will work again normally, but it happens pretty frequently and can be very frustrating if you need some work done in a hurry.
As I write this, I've tried the 5 and 6 keys and they're working now, but when I started to write it they would not. Has someone else had similar issues? Is it the hardware or something I can address myself?

Thinkpad S440 Keys not responding

Hello Community!
I have a Thinkpad S440 from 09/13 and in the last few weeks the p-key as well as the o, the 0 and sometimes ü,ö,ä (German keyboard) are not responding.
They don't react to keypresses, however, after pressing them a few times they become responsive and do so every press of the key, unless I leave them alone for a while, then they become unresponsive again.
It's not dust or dirt, I've been using pressured air to clean it it changed nothing.
Now I've been told that this might be a problem with the fixation of the keyboard, the way it stops and starts certainly points to this.
Now, do I have to send it in?
I know how to open the thing and I have professionals around who might do it but I'm afraid of voiding the warranty.
What shall I do?
Thanks for reading!

I opened the backcover and had a look.
However to look at the keyboard you'd have to remove basically every component of the interior and neither me nor anyone I know dares to do that.
I tightened every lose screw I could find, one screw at the battery showed clear signs of unprofessional usage too.
This seems to have made the problem A BIT better, the keys work more often but not well at all so it's definitely a problem with a connector.
I think I can't but use the warranty.
I don't feel too well with sending my laptop with a lot of sensitive data but I think I'll have to.

HP 15-d069wm TouchSmart Notebook PC keyboard certain keys not working

Certain keys (space bar, left shift key, z, x, c, v, b, n, m , comma, period, /) and number keys (1, 2, 3, 5, 6, 9) on the keyboard of my laptop are not working. I already tried to do several hard resets (disconnecting power supply and taking out battery) but that didn't help. I also "uninstalled" the keyboard using the device manager, that didn't work either.
The laptop was bought in June 2014. I'm using an external USB keyboard right now.
Any ideas how to fix that issue?
Thanks!

Apple Bluetooth Keyboard : ESC Key not responding

I'm using an Apple Bluetooth Keyboard with many Apple products (MBA, MBP, iPad) and i have a big problem : The ESC key is not responding. Everything else is working on my keyboard except the ESC Key. Do you know how to fix it ?

Hello:
It is, of course, possible that the KB has failed....
Try resetting the PRAM. If that does not help, I think it is time for a new one.

After thoroughly searching the communities and repeating steps others have followed, I am still not able to use the volume keys. I need help.

Open Firmware startup keys not responding

Hi there,
My Command-Option-O-F combination at powerup is not responding to get me into the Open Firmware.
Any thoughts?
Cheers,
Aaron

Intel Macs do not support Open Firmware rather they use the EFI - extended firmware interface. You can start up in safe mode, single-user mode, or verbose mode. See the following:
Startup key combinations for Intel-based Macs.

Portege M400 Fn Keys not responding

My function keys on my laptop are suddenly not responding.
I've never had a problem with them prior to this, but I'm not sure how to fix them at this point.
When I hit the function key by itself, the green light beneath F11 still responds, but that's really the extent of the activity.
I've had the laptop for almost a year, and I'm running an XP OS.
Any comments or suggestions are much appreciated.
Thank you!

Hi again ;)
I mean the Common Modules is a Toshiba driver which is necessary and important for the FN button usage.
You can find it on the Toshiba driver page:
http://eu.computers.toshiba-europe.com -> Support & Download -> Download Drivers
There you have to choose your notebook series, OS and then you could download it.
Then unzip the package and reinstall it on your notebook.
Hope this helps

Soft keys not responding

hi
i followed the steps in the tutorial http://www.thetechlabs.com/tutorials/flash/creating-a-flash-lite-application-with-flash-cs 4-and-actionscript-20/ but when i run the application in the device central emulator, the soft keys do not respond. i even edited the action script code to change the text in the textboxes when the soft key is pressed but there is still no response.
Thanx

Hi dahaka2010,
Has your problem been solved?
On what profile/s and what content type/s were you trying it out? Wallpaper, Screensaver and Embedded in HTML for example do not have soft key functionality. Some profiles also might not support soft keys altogether.
Thanks,
Nandi

F keys not responding

I'm running tiger still but my F1 thru F11 keys do not respond does anyone have a idea how to fix this?

Do they work if you hold fn and hit them ?
If so open System Preferences/Keyboard & Mouse, click the Keyboard Tab and uncheck "Use all F1, F2 etc, keys as standard function keys"
