Macbook Keyboard Partially stoped working

ok i have a macbook and the other day my keyboard randomly stoped working. now the FN keys at the top work including the brightnesss, volume, expose, dashboard, ect... but none of the letters work (a-z) also the enter key doesn't work caps lock doesnt work shift doesnt work and so on, BUT the arrow keys work
i went to the apple store yesterday and the genius told me they didn't know what was wrong with it and to reinstall leopard. only problem is i don't have my second dvd that came with my computer to install all the ilife08 stuff and i dont have the office 08 cd that was provided by my school. so when i got home i plug in my external hard drive which i use for time machine, pop in the disk and do a full restore to 3-7-08 after about 2 hours of it restoring it finally was finished, leopard boots up and finally everything works! so i go to bed. wake up this morning, go to class and i'm using my laptop in class to take notes in word. all of the sudden when i go to type another sentence the keyboard once again dies! i wasn't doing anything on my computer besides word. i believe the only other application i had running was little snich. so now i'm not sure why in gods name this has happened to me 2 times. the mac genius told me it wasn't a hardware problem and most likely software. what could be wrong????
thanks SOOO much in advanced if anyone can help me

I can only be of limited help, but I use Little Snitch and it's never given me any problems.
It's possible that some application is hijacking the keyboard input, but that seems to bizarre. It could be hardware, since the cable that connects the keyboard to the laptop is directly under the keyboard and it could be shorting out intermittently.

Help - My macbook keyboard doesn't work after being sprayed with windex.

My mom cleaned my keyboard with windex. I'm assuming that this short-circuited something or other so the keyboard isn't being processed. Anyways, I let it dry out for a day and some of the keys work now, but the macbook randomly shuts off.
Should I let it dry off for a little longer?
Do I need to replace the sheet underneath the keyboard?
What should I do?
Thanks.

I have a new TX2 1300 also and i have the same exact problem. When I use the touchsmart program in laptop mode - no issues with the keyboard. BUT if I use the Touchsmart program while rotated in tablet mode - the keyboard turns off and is not usable until I reboot my laptop. Very repeatable. I also verified I have the latest BIOS. After I read your post yesterday I called the HP support and they were not able to reproduce the issue on their lab compter (a TX2Z 1000 - NOT a TX2Z 1300). I updated my bios with the tech on the phone just to pacify them - and I still have the issue. The tech then checked her database and amazingly enough HP knows of this issue and is working on a patch for the Touchsmart program. They are going to email me when the patch is ready.
I have another issue - and I am curious if you see it too. My screen goes out of calibration constantly. Basically I lose the touch sensitivity right around the WIndows start button on the lower right part of my screen. Affects both capacitive (finger) and digital (pen). I have to run the reset progam in the NTRIG Touch Tuning utility in the windows control panel to get that part of my screen to become responsive again. Very disapointing - have you seen any issues with the touch screen sensitivity on any parts of the screen ?
Thanks,
Kevin K..

Why doesn't my macbook keyboard or mousepad work?

sometimes my keyboard and mousepad simply stop working. I used to think it was because maybe it was overheating but leaving my macbook alone by itself for a few hours with the lid closed doesn't get it to work. since it simply gets stuck there I'm forced to hold down the power button and restart it. This has been the only thing that's been allowing me to use my macbook. I have to restart it for the keyboard and mousepad to work. Unfortunately the rate at which I've had to do this has been increasing. Today I've had to restart it 4 individual times which I know is awful but I have no other option. It's over a year old so I would have to probably pay massive amounts of money to fix it but I'm really annoyed with the situation. I'm a student and I can't keep having to restart my macbook in the middle of my studies.
I don't know what's been prompting this, there's no particular trend. It just happens when I'm watching a lecture, taking a quiz, or on facebook. My macbook hates me and it does so randomly. Why is this happening and is anyone else having this problem?

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V. Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report—it will be very long and not helpful.

My Macbook keyboard won't work and the computer is shutting down at random. Any advice?

I have a Macbook that is approximately 2 years old. It had water spilt on it but since then everything else is working fine.
The keyboard won't type at all, it did on the original start up after the water damage was assessed within the computer's shell. Now not at all. I'm using a USB keyboard for the time being.
Also, it shuts itself off at random. There is a dull click and the screen goes black, then when you attempt to restart it it loads a little and then it clicks and screen goes black again.
Any advice or suggestions would be greatly appreciated.
Thanks.

Hello Rach Ryan
First I would try closing the app from multitasking and then launching it again. To do that, double tap the Home button and then swipe up on the app to close it completely. If that does not work, then I would restart your iPhone.
iOS: Force an app to close

Turn your iOS device off and on (restart) and reset

Thermal Problem - MacBook keyboard is not working properly

I have a strange problem which I have never seen beeing reported before. While working with battery power everything works normal. When loading the battery or under heavy processor load the Macbook heats up and the keyboard has the following problem: the number keys 1 to 9 (and only them) do not work any more. If the Macbook cools down, the number keys start to work again.
What can be the problem ?

Sounds like you may have a circuit laminate problem with the keyboard. You need to contact apple to get help for this problem.

Please help

>When I switched external USB keyboard, laptop keyboard working.
This means that keyboard controller is OK and the issue seems to be related to the internal keyboard. Faulty internal keyboard needs to be replaced to resolve your problem.
Are you from Poland?
I guess you could get a new keyboard from Toshiba authorized service provider who is available in Poland. Also a common keyboard (84 keys) should be compatible.

Qosmio F750 - some keyboard keys stoped working

Hello
I have a Toshiba Qosmio F750 since 3 months ago. The other day, i just powered the laptop and noticed some keys (a,b,n,enter...) were not working at all. I tried to clean blowing under the keyboard and nothing. Also in the windows booting these keys dont work. Anyone with the same problem?
Someone knows how to solve this?
Is quite annoying having to use an external keyboard with a 3 months old laptop....
thank you!

Hi
I think only keyboard replacement could solve your keyboard button problem.
It looks like the single buttons are faulty and since the single buttons cannot be removed, the whole keyboard needs to be replaced.
Get in contact with an local Toshiba ASP. The warranty seems to be valid and the fix should be done free of charge sorry to say this but it seems you had simply a bad luck :(

MacBook keyboard is not working properly, highlights randomly

Over 2 years ago my MacBook was fixed for liquid damage, hot tea was spilled on it while it was closed. Just recently it started acting up, highlights randomly, cursor jumps around while I am typing, thus deleting what I have typed and etc. Please, is there any remedy I can do myself, at home?

Your alt (aka opt or ⌥) key is stuck down. This seems to be quite common these days.
Try teasing it up with the corners of two credit cards or similar flexible, non-conducting tools.
If that doesn't work, the wafer switch underneath may be damaged, in which case it'll need to go in for service.

Keyboard on 2006 macbook keyboard is not working properly. I'm just getting weird symbols when I type yet an external keyboard works fine. Is there something I can reset or replace? Please help!!

Why won't my Macbook keyboard work?

My Macbook keyboard is not working. It was fine earlier but upon using it again later I realized that all the letter keys did not work. Whats more is when I try to type with a letter key the mouse cursor vanishes and the trackpad registers single clicks as doubles. I can use a USB keyboard fine and typing with reverses the aforementioned trackpad error (though it returnsw as soon as I type with the built in keyboard again).
Any ideas?

Further, do you know for sure that your MacBook Air model supports keyboard lighting? Not all of the models support this.
Which model do you have? (Go to About This Mac (under the Apple logo in the menu bar), click "More Info" toward the bottom, and tell us what the top 2 or 3 lines say in the resulting display.

MacBook keyboard and trackpad not working

Hi,
I have had my MacBook for about a month and it has been great. However yeasterday the keyboard and trackpad stoped working. I have been abble to use it with a usb keyboard and mouse, but obviously this is not a permanent solution. There seems to be no connection between the computer and the mouse. The lights on caplock and numlock don't work and in System Preferences> Keyboard and Mouse there is no trackpad option. I assume an internal connection has come appart but I don't want to open it up as I am not perticularly experienced in these maters.
Any feedback would be apreciated

OK, I have had the same problem. I had a look on these forums, but the best thing to do is call Apple Support. They told me to do the following:
Unplug the mains adaptor
Remove battery
LEAVE the machine for like 50 seconds.
HOLD Power button for at least 5 seconds.
Install battery
Attach power adaptor
Before turning the machine back on, hold down: Option Key (Alt. with the switch symbol) Control (Apple symbol with square thingy) P and R.
While holding these press the power button, KEEP holding them, and the machine will restart again, chiming again, KEEP holding and the machine will restart a third time: on the THIRD restart and the THIRD chime, release the keys, and the login screen should come up, and machine should be OK.
This is what worked for me.
Incidentally, last night the machine stopped recognising the keyboard and trackpad, but responded with external devices, but this morning, it wouldn't even start. This solved both issues, it is so far working fine.

After System Update keyboard doesn't work -MacBook

Here is what happened and I was able to fix, someway... but not definetly.
I updated to Snow Leopard and everything was fine. After I launched System Update to finish the update, I installed a few ones then I rebooted.
At the login I realized that some of the keys didn't work anymore. Namely
0 = P ] ; \ / ENTER
those what I found.
With the help of the virtual keyboard I was able to take a look at the log and I noticed that the /System/Library/Extensions/AppleHIDKeyboard.kext was updated just before the last working configuration...
Luckily I had a bootable backup of the system before Snow Leopard, so I boot from the external USB drive and copied the old AppleHIDKeyboard.kext in place of the new one, that I saved with .bak extension.
I rebooted and the keyboard was properly working again.
I think my fix is "dirty". I experienced some slowdowns here and there and I found a log message stating:
com.apple.kextcache[271] AppleHIDKeyboard.kext does not declare a kernel dependency; using com.apple.kernel.6.0.
I'm wondering why the keyboard stopped working and if there is a better way to fix it.
Any comment? (Please)

It is never a good idea to mix system components like kext's from different OS X versions. If you right-click on for instance the AppleHIDKeyboard.kext & choose "Show contents" you will see that it is a bundle composed of many individual files. Many of these files contain information about files in other OS bundles. Similarly, other OS bundles may contain info about the files in this bundle. This tells the OS what +set of files+ it can & can't use for various functions.
IOW, kext's are not self-contained, functionally independent items. When you replace one with one from a different OS version, its info about other files usually won't be right. This can & very often does cause problems. Some are minor but others can cause progressively greater problems, eventually damaging the OS enough that it becomes inoperative.
So, your fix is almost certainly "dirty."
It's also not addressing the source of the problem. There is nothing wrong with Snow Leopard's AppleHIDKeyboard.kext file (version 1.2.0). Snow Leopard works perfectly well with my & thousands of other users' MacBooks. The cause of your problem could be many things, but this is not one of them. If you can accept that, there are several things you can do to find the cause, starting with running the Apple Hardware Test to see if it finds up any problems with your MacBook.

Keyboard is not working on Macbook 1.83GHz with Windows XP Pro

Hi
There is a problem in Macbook 1.83 GHZ (Macbook 13-Inch Mid 2007 Combo) the keyboard is not working some times when I boot from Windows XP install Disk, after installation of Windows XP Operating System.
Either I install first Mac OS x 10.4.9 then Install Windows XP Pro through bootcamp 1.2 Completion of both Operiting System I boot through Windows XP bootable CD OR I install Windows XP with out Mac OSX, in both conditions when i boot my computer through Windows XP bootable CD some times my built in keyboard (or external USB keyboard) does not work.
Not only one Macbook is effected there are many.
I request you to please advise to resolve this hot issue.

Has any one had problem like this, plz share to resolve this issue.

White Macbook (purchased in march of this year) keyboard no longer works.

I was typing something, and as soon as I plugged my ipod in, the computer started going crazy. if i clicked in a typeable space (Adress bar of the internet, word processors, anything) it repeated the "b" key endlessly. not knowing what to do, i shut it down, and when it restarted and i went to log in, the keyboard wouldn't work. not including the trackpad. i grabbed my dad's PC and looked up what to do, and it said to take the battery out and restart it, and now for some reason my battery wont light up when i put it back (it's locked in all the way). i can still turn it on but i still can't type on it. what do you suggest that i do? i can't do anything since i can't log in.

It might be worth trying the following first:
Reset PRAM and NVRAM: http://support.apple.com/kb/HT1379
Reset SMC: http://support.apple.com/kb/HT1411
Since your MacBook is still under warranty, you can always take it to a local Apple Store or an Authorised Apple dealer to let them look at it. They will not charge you to look at it, and any necessary repairs should also be free of charge under the warranty.
Hope that helps.
