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.

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.

Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

Keyboard issue I have a iMac thats about 4 years old, and now the keyboard is not working properly. some keys do not work. Any suggestions ?

I think I may have a virus! My keyboard is not working properly. When I press the zero key, it doesn't appear. Other keys that do not work include the directional keys, delete key, and others. I tried everything that I can think of to fix it, but nothing sesems to be working. Should I bring the keyboard and=/or the entire computer into my local Apple store+? see, the +? appears before the question mark, and I didn't put it there! Thanks!

No need to take the computer at this stage. Just take the keyboard into your local Apple store for examination. If you have another machine, not necessarily Apple, you could try the board on that or perhaps a friend's machine … they are largely universal.
You do not have a virus.

My keyboard does not work properly when texting etc

Hi All

Cheers for any support in advance.

I have rebooted and synchronised it with the mac. I dont even have to touch the screen now and some letters get picked up.

My keyboard is not working properly. To get an a i have to type a q

my keyboard is not working properly. To get an a i have to type a q. To get a w I must type a z. M is the semicolon. Period is less than sign. I have turned off the computer and unplugged the keyboard and it still does not work. Running OS 10.6.8 Just noticed I have to use caps to get numbers.

Somehow I had gotten my keyboard preference changed to French.
If you have more than one keyboard layout enabled (checkmarked in the Input Sources section of the Language & Text control pane in System Preferences), then pressing Command-Spacebar or Command-Option-Spacebar will switch the active layout from one to the next.
You can prevent that from happening by either -
• Reducing the number of enabled keyboard layouts to one; or
• Turn off those two keyboard shortcuts. You can do that in Syatem Preferences > Keyboard > Keyboard Shortcuts; click the Keyboard & Text Input in the left pane, then uncheck the two "select" items in the right pane.

My Mac App Store on my MacBook Pro does not work properly.

My Mac App Store on my MacBook Pro 15 inch does not work properly. When i go on to the app store, my wi-fi resets and then my app store quits. Why is this? How can i fix this problem? Please Help

Back up all your files, on boot up when you first press the power button, press CMd and r and keep pressing until you get something apart from a apple logo. Then click reinstall Mac OS X or something like that. You may be prompted to insert your disk.
Good luck

My built in keyboard is not working properly on my iPhone4S

My keyboard is not working. When I type it presses multiple letters and periods and spacing. It is like the sensitivity of the keyboard has increased 100% but for no reason. Please help.

iPhone: Troubleshooting touchscreen response

The letters e-o on my keyboard is not working properly. Nothing spilled, Laptop not dropped. I've cleaned out underneath and everything seems fine. Problem happens intermittently but seems to get worst the longer I have the computer on. Any ideas?

Macbook pro OSX Version 10.9.4
Top row of letters, e-o, are sluggish and not working each time press them.
I have cleaned underneath them, I did not spill anything or drop the computer - It just started to happen.
Any ideas????

The behavior of the keyboard not responding after the machine is on and used for a time sounds a lot like swelling under the keyboard…the battery is under the keyboard, processor to the side, and issues with trackpads and keyboards have often ended up being a battery swelling. Makes it worth while taking the MacBook Pro in sooner rather than later to have it checked. The techs may ask to keep the machine for a few hours so they can run it long enough to see the behavior if nothing shows immediately on their diagnostics.
When things like this happen, my attitude is on the conservative side…check it out before it can get worse.

Keyboard backlight not working properly

Hi, first of all, thank you for your replies and sorry for the bad grammar (english not my first language).
Background info:
I have a 17inch macbook pro 3.1
Core 2 duo 2.4
Im running Osx 10.7.2
Upgraded HD and memory.
Issue
I had this computer since 07, no problems until about a week.
keyboard back light doens't work properly, I have tried resetting SMC and using an app called LabTick.
ONLY if I press slightly (without actually pressing completly) the keys "F" or "G" the backlight works.
when it does it responds to the F8-F10 keys and goes off on light rooms.
Its pretty annoying, it can be working for hours then it stop working and I have to play with f and g keys to get it working again for a long period of time.
is this a common issue?, is there a quick fix, I really dont wanna pay about $800 to change the whole logic board.
Thank you

emmm... anyone had this issue?
No and don't think you will.
I think you have a problem with your computer. Maybe a clean install of the OS might fix it, maybe not.
If not then there is something wrong internally which can not be fixed without figuring out what internal part is causing it.
That can't be done on this forum.

Ergonomic keyboard 4000 not working properly

Hi all,
I have a very weird problem with my MS Ergonomic 4000 keyboard (USB) connected to my MacBook Pro (OS X 10.7.5). I've connected it in the past and it worked just fine but now, it's not functioning properly. I'm typing this on the MacBook keyboard, but here's what happens when I type the letter i using the ergonomic keyboard: i9
This is just from one tap of the letter i. It only happens with the lower-case i, and not with when typing a capital I (shift+i) This happens with other keys as well.
I searched the forums and support sites and so have since both removed intellitype and then installed intellitype 8.2 for the proper OS, but still no change.
Any help / advice will be greatly appreciated!
Thanks!

Thanks Esquared,
I have the same problem in safe mode. I just tried it on my iMac and it does the same thing there. Also, when I press Shift + any key, a dialog pops up asking me to assign a function to a number key that I didn't press. The numlock key types "4" as well.
So I'm guessing that the issue is with the keyboard itself. The question is, can anything be done? It's relatively new and I'd hate to have to just throw it out.
Thanks in advance.
