Keyboard issue: Super-sensitive "z" key all of a sudden...

Just noticed in the last day or two that the "z" key on my q10 has become super sensitive, it is almost impossible to type an "s" on the keyboard without a "z" being added on...in fact, you don't have to fully depress the "z" key to get a z, you just need the fainted pressure on it. Ideas? Has to be a hardware issue, doesn't it?

Thanks for trying that, stheemka! We want to put a stop to any further frustration you're experiencing with this issue on your Q10. Since the device isn't damaged and is less than 12 months active, it may qualify for warranty replacement. If you haven't already been presented this option, please follow my handle (DionM_VZW) so that we can direct message each other (I've just send you a follow request).

Keyboard Issues Intermittent Use of Keys & Tracker Mouse

Hello All,
Look forward to some help please.
Not sure what is wrong, seems there are a number of weridy things going on. Nothing dramatic, but all very annoying.
About a month ago replaced the HD myself, re-installed, everything seemed fine. Then had the following problems.
1 - 'U, J, M' keys stopped working. After PRAM zap were ok.
2 - At a later date the directional 'up & right' keys and the 'Return' stopped working, no explanation just sometimes works with a restart or a complete power down and reboot.
3 - Tracker pad stops working completely then plug in a PC USB mouse and might start working again, might not.
4 - Screen goes black and I have to press the power button to get the machine up again. This is with the power cable plugged in and power on.
I appreciate this machine is oldish but these are strange enough problems, with no consistent reasons for happening that I can think of.
Lastly I got the following message when it went completely south on me.
I'd appreciate any help possible, other forums have not been able to even post a response. Many thanks again.
This morning I had points 2 & 4 happening and had to power down reboot.
Mike

Mike:
Welcome to Apple Discussions.
Your, apparently, random keyboard issues may be due to either faulty connection of the keyboard ribbon cable to the logic board, or a defective/damaged ribbon cable. I suggest you go back in and make sure the connection of the ribbon cable to the logic board is secure. If necessary place a new piece of kapton tape on it to secure it.
I further suggest that you boot the computer from the Apple Hardware Test disk that came with your computer, and run the extended tests in a loop (hold down Ctrl + L during tests) and let is run for a while, as intermittent issues may take up to several hours to show up.

Tab key all of a sudden is Command-Tab in client windows...

All of a sudden, whenever I use the Tab key when connected to any client, it acts as Command - Tab. For example, when I attempt to tab to another field in some form and press Tab, it brings up the open applications thing and scrolls through them. If I then press any other key, it acts as Command - "(whatever key I just typed)". If I press a k key, it acts as command - k. This only happens after pressing the tab key.
So basically, after pressing the tab key, all subsequent key presses act as if the command key is also being held down.
I have to disconnect and re-connect to that client to get it to stop doing that.
I do not see anything in the prefs to help with this. I did see one other forum topic about this but there was no fix posted. Sticky keys show nothing strange is going on with my keyboard. This is definetly an ARD issue. All local tab and command keys work as expected.
Thank you very much for any info regarding this.

I found the issue... I use TypeItForMe, and part of the instructions for typeitforme is to turn on "Enable access for assistive devices" in Universal Access preferences. When this is turned on, in ARD when connected to a users machine and controlling it, if the Tab key is pressed all subsequent key presses act as if the Command key is also pressed.
I have turned off "Enable access for assistive devices" and now ARD behaves normally. However, I am unable to use TypeItForMe the way it's supposed to work.
So, not sure if it's a bug or normal behavior, but sure wish it wouldn't do that...

Help! My Keyboard and mouse will not work all of a sudden on my G4

I am having a problem with both my keyboard and mouse. I have a graphite G4 and recently had to run disk warrior on i. I have had endless problems with this computer and even have a 2nd hardrive on it since it only came with a 10Gig. Needless to say it is all I have right now. I am running os x 10.2.2 on it and a few days after I recessitated it with disk warrior my keyboard and mouse suddenly went dead while I was on the internet. I tried pluging the two into different usb ports both on the tower and also into the flat panel mac display that it came with and nothing. I plugged in my wacom tablet and that works. i then tested the mouse and keyboard on my husband's dell laptop and they work. I cannot reset the PRAM b/c the keyboard won't work! What do I do??????

Besides removing the battery, you can do a PMU reset which will zap PRAM. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial
You only describe your Mac as a G4 graphite, which I believe is a G4 AGP. Here’s a diagram showing the location of the PMU reset button.

Hi,
Greetings !!!
I would like to know what is the root cause of Iphone camera hanging ?
I am very frequently experiencing Iphone 5 camera issues like while taking photos all of the sudden the camera going to hang mode with full of pink & black line.
I noticed while camera app turns ON the phone going to hand.
I went to apple services server with this problem & they said they didn't see any errors.
Kindly response with my request, and provide me the solution.
Thannks & regards,

That often happens with cameras when you take pictures of a computer screen. LCD screens "flicker" and the camera will often catch the flicker.

All of a Sudden, lots of corrupted files

I've never had this issue with lightroom 5. All of a sudden, I'm getting corrupted files, some of them disappear , and some seem to be corrupted AFTER I've already processed it. Very odd. I use a Nikon D7100 with Delkin Devices 64gb SD 633x. I just got these new Delkin Cards, which up until now, were smokin'! Now I don't know if its the card or lightroom. The cards were formatted like usual before I used them. Any ideas? Thank you in advance.
Ken

Ok, I got the Delkin card reader and I only had 7 corrupted photos instead of dozens out of 500 imported. So there's a positive.
As for the question of the RAM upgrade, I got the RAM from Out of This World Computing http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/. It was installed by UbreakIfix (You Break , I fix). I know the "Mac" guy over there and there have been no other issues otherwise. This Macbook flies better than ever.
The fact that you are still seeing corrupted files implies that the reader wasn't the issue. It is possible that the built in reader just maps to different parts of memory than the external one. Normally I would 100% trust RAM from OWC. I've bought memory from them for decades now and never seen a dud. However, you might have some bad memory here. One thing to try is to revert to the old memory and see if you still have the problem. It is strange that you are not seeing massive problems just running the computer though. If images are corrupting that frequently I would expect that to happen to other parts of memory too. Have you checked for a hard disk problem? Open Disk Utility (from /Applications/Utilities) and select the top level of your hard disk. Check if it says "S.M.A.R.T. Status : Verified" in the bottom of the screen. Then click on the hard disk icon that represents your internal disk (usually "Macintosh HD") and click "Verify Disk". If there are any errors found, it will tell you how to repair them. If you don't see any errors, try doing a "repair Disk Permissions".

Ipad doesn't recognise wireless keyboard apart from the function keys this has only just occurred . Previously no issue at all

Ipad 2 doesn't recognise wireless keyboard apart from the function keys this has only just occurred . Previously no issue at all.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

I cannot type a capital i using the left shift key. also keyboard now putting the cursor in a different place than where i type. Checked speech keys, all fine. Batteries fine.

i cannot type a capital i using the left shift key. also keyboard now putting the cursor in a different place than where i type while i am typing. Checked speech keys, all fine. Batteries fine. Also used the keyboard check program on the imac, shows key ok.
wireless mouse will suddenly scroll down horizontally and won't stop. when i am on a webpage it will bounce back to the previous page without my doing so. i have tried adjusting the mouse several times, turning it on and off, and now am using my wacom mouse which also seems to have issues with this computer. i have only had this a few months and getting very frustrated.

Can you try a different keyboard to see if the problem persists? Also, you have 90 days of phone support when you buy a mew mac.

My keyboard on macbook pro (laptop) is acting weird. One key is not responding at all. Have verified using Keyboard viewer and some other keys are printing the unresponsive character at random.

Is it a damaged keyboard ?
The laptop is just 2 months old, will Apple replace it with a new one if its indeed a damaged keyboard or just repair, I use it for official purposes so being without a laptop is not much of an option.

No one here works for Apple, so we don't know what Apple might or might not do. If it's a genuine defect, they will of course repair it under warranty. It is not their responsibility if it effects your ability to work or not, so that's on you.
If, however, they determine that the key is problematic as a result of your misuse of the laptop, then everything is on you. And trust me, if they find a glob of dried up beer or coffee there, they will charge you.
Your only choice is to take it in for repair.

Delete key + Keyboard issue

Hey, I have a MacBook from mid 2007 that I use for Boot Camp. I was wondering if there was any way to have some key that would be the equivalent of the delete key on Windows (I am running XP).
Additionally, on XP, for whatever reason it likes to go to the French keyboard, which is annoying since I will go for a "?" and get a capital "é". Anyone know what to do?

Sounds like you have a French keyboard selected. In Control Panel select the Regional and Language Options. Now click on the Languages tab and select the Details box. Here you can control which keyboards are available under Installed Services.
If you poke around a bit you will be able to address the French keyboard issue.

Just purchased a new mac mini 3GHz Intel Core i7, with 16GB ram version 10.10.1. With it i purchased a new wireless keyboard. All of a sudden I was not able to use the #1 key. I thought I had a defected newly purchased keyboard. I pulled out my older wireless keyboard, and the same thing happened. It must not be the keyboard if it happened to two different keyboards. I have a habit of restarting my computer, when things don't work, I find it helps, and sure enough, everything works. Today, it happened again. Does anyone know what is causing this to happen?

Wired keyboard issues-caps lock won't turn off and other keys do not type

I sat down today to use my May, 2010 iMac. Fully up to date with Lion.
I am using a WIRED keyboard.
The caps lock key is permanently on and the remaining keys when pressed do nothing. They do not work. You can press the keys down but they don't type any letters or symbols of any kind.
I cannot log in because I can't type my password as the keys don't work.
I can't do a PRAM reset because the P and R keys and others don't work.
I don't know what an SMC reset is but I can't do that either because the keys don't work.
Why would a keyboard stop functioning? Yesterday, it was just fine. Now it doesn't work.
What causes the caps lock key to stay on?
I have unplugged the keyboard etc, but nothing changed.
Doesn't anyone know how to correct this problem? Do I just need to buy a new keyboard?
I called Apple but they were closed.

Please read teh directions for an SMC reset:
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
