Macbook Pro 15" 2.2 Keyboard Backlight Flashes

I am hoping to get some help with a problem I am having with my keyboard backlight.
The keys flash / flicker on and off even in low light conditions.
I have tried adjusting the screen backlight down thinking that it was casting enough light on the sensor that it would toggle back and forth between low and high light.
Lights off in the room, it doesn't matter!
I even downloaded a program called lab-tick. Didn't make a difference.
The computer has Snow Leopard 10.6.2 installed if that matters.

Cleared the PRAM and put a little electrical tape around the edges under the keyboard to make sure the sensors were only reading ambient light and not keyboard light and it worked fine.

Macbook Pro (10.6.8) keyboard backlight wont turn on

I was reading some articles to try and fix it myself but I noticed a lot of people have problems with their keyboard backlight because they have the box located in
System Preferences > Keyboard > Automatic Illuminate either checked or unchecked. I checked my keyboard settings and I don't have that box at all!
I got my macbook in 2008, 2009 so it's a slightly older version. I need help fixiing my keyboard!
It hasnt worked for awhile now but I just never noticed it.
It never turns on when it's dark either.
When I cover the camera lens the display dims so it pretty much works
The only thing I noticed that no one talked about was that when I press FN + F5 or F6, I hear that sound that indicates you can't use that option. but when I try with the FN + f1 or f2, it works just fine.

Macbook Pro 17inch late 2011 keyboard backlight not working

Recently near the end of sum me 2014 I only noticed the backlight keyboard not working at all. I have done the following to try and rectify;
1. Reset SMC
2. Rest NVRAM
3. Disconnected battery and the above
4. hardware test online, result showing no issues found.
with all outcomes proving nil. Pressing Fn + F5 or F6 does show the brightness either increasing or decreasing but with no light. I then opened her up and disconnected a cable that was to the LHS of the RAM boards but this only powers the White Sleep LED and not the backlight keyboard on this 17inch model. My next step is to remove the mother board and find the actual cable that does power the backlight LEDs and ensure that it is connected. Similarly around the same time I noticed this with the backlights the fans were running fast. However the weather has gotten cooler and the mbp is not running fans as it was when it was in the warmer months.
Do I have to remove the motherboard and actually make sure that the connector for the backlights hasn't been dislodged?
Anyone out there with a 17inch mbp late 2011 that has had this problem please help.

Thanks Ogelthorpe, I found an excellent video (not in english but it didnt matter) https://www.youtube.com/watch?v=8HNAGodYMNA .
What I found was that the keyboard backlight is intergrated into the black plastic cover that is between the motherboard and the back of the keys/LEDS and its all one piece back to the connector that connects to the motherboard under the LHS fan. I need more details to find out if the LEDS are controlled by a chip or what, but it seems to me that I need to visit an apple store/repairer, however this will be really difficult for me as Im in an isolated location. If there are further tests that I can conduct on my own, I would be grateful. Even if there are tests that Apple themselves conduct to find out what the problem is

How to buy a MacBook Pro with a Swedish keyboard?

Hello,
I work at a University, we have a new researcher here that wants us to purchase a MacBook Pro with a Swedish keyboard. For three weeks we have been unable to get anywhere. We have a University account manager, but she hasn't made any progress. We are willing to pay the retail price of a MacBook Pro in Sweden, we just can't get anyone to take our money.
We can't be the only University in America that has a need for foreign language support.
Thanks for listening.

If you really must have a Swedish physical keyboard (which is not necessary for typing Swedish unless the person can't type without seeing what is on the keys), the place to look for one is

Transferring data from 750GB backup drive to new MacBook Pro with 256 Gb PCI-e flash storage?

Yesterday my late-2008 aluminium unibody MacBook died - absolutely and definitively. I've tried SMC reset multiple times to no avail. However, it served me well for almost six years and it's now time to move on. I've decided to buy a 13 inch MacBook Pro Retina with 256Gb PCI-e flash storage. Obviously, it will come with Mavericks installed as the operating system.
When it died, my MacBook was running OS X 10.8.5, the original hard drive had been replaced with a Western Digital 750GB, 7200 rpm drive of which I believe about 350GB was used. I keep two x 1Tb Lacie Rugged backup drives, each of which has both Time Machine and SuperDuper Bootable Clone backups.
My questions are these -
1.     How should I proceed to transfer my data from my external backup drives to my new MacBook Pro Retina, given the difference in storage capacity of my existing backup drives and my new MacBook Pro?
2.     I have over 32,000 photos in my iPhoto Library which, obviously, consume a big slab of disk space. I'm not sure how I go about 'quarantining' the iPhoto Library so that it doesn't use all the flash drive storage.
3.      One of the Lacie Rugged's has a 'triple interface' - i.e. USB 2, Firewire 400 and Firewire 800. The other has a USB 2 and 2 x Firewire 800 (IIRC).    The MacBook Pro Retina has two USB 3 ports and two Thunderbolt 2 ports. I want to continue to use the Lacies as my backup drives. Am I better off to use the USB ports or should I invest in a Thunderbolt to USB cable? Does it make any real difference in terms of backing up (which, in my case, doesn't have to be all that speedy).
4.     What else should I be thinking about? I know I'm bound to have overlooked the most obvious problems but can't think what they may be ...
Cheers
Tricia

USB3 is backwards compatible with USB2, so you can use the old USB cables. For faster data transfer rates, Firewire 800 would be available using this adapter:

Firewire 800 is about twice as fast as USB2, theoretically.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Using MacBook Pro as display and keyboard

Morning.
I have an Mac mini Server 2,53 10.6.4 without display and without keyboard. How can I use my MacBook Pro as display and keyboard to configure the server?

If you are setting up a server you can use Server Admin tools to set up a new server remotely. You would need to install the Server Admin tools on your MacBook Pro and then do the remote install procedure.
You need to collect the serial number and the Mac Address of the Mac Mini Server to enter in as the information in the Remote Install during the installation process you will be prompted to chose Remote Management and SSH for options that way you will be able to connect to the Server Remotely at anytime when configuring or afterwards.

Can I buy a MacBook Pro with a foreign keyboard in the US?

I will be moving to Sweden soon and was wondering whether or not I am able to buy a MacBook Pro with a Swedish keyboard, in the US? It is a lot cheaper buying one in the US than in Sweden (I would save a few hundread dollars). The computer I am interested in is the 13 inch MacBook Pro with the Retina display.
If I am able to do so, do you know how I would order it? I can not find any options for it online...
Anyways, thanks alot in advance!

call 1-800-MY-APPLE and ask. You will most likely have to order it over the phone.

I download adobe flash player for my macbook pro, but nothing that requires adobe flash player works

i download adobe flash player for my macbook pro, but nothing that requires adobe flash player works. i haven"t tried much, but only because i have no idea what to do.

After you've installed Flash Player (you have to mount the disk image by double-clicking and the double-click the insatller package) restart your browser and go to youTube, for example, -> http://www.youtube.com/ - and see if the videos play.
Call back if you need any further help.

Hello! Does anyone knows if its possible to change a US keyboard of a macbook pro for a portuguese keyboard. And how much it is approximatedlly. Thanks

Welcome to the Apple Support Communities
You will have to return the Mac and order one with a Portuguese keyboard, if you bought it less than 14 days ago.
If not, you will have to buy a new Mac (that's because some keys may not fit onto your MacBook Pro keyboard) or just set up OS X with a Portuguese keyboard but with US keys

MacBook Pro (Retina, 13-inch, Early 2013) Flash Storage Failure

So I've been getting Kernel panics for the past few weeks on and off. So I ran the Apple Diagnostics and right off the bat told me my hard drive was failing. I'm going in tomorrow to the Genius Bar. I have Apple Care and Time Machine.
My question is how are they going to replace the Flash Storage? I can't find anything online about one failing let alone being able to replace/upgrade one.
Thanks for the help!
Nate

You need to replace the flash storage. Note that the MacBook Pro with Retina display comes with flash storage because a SSD doesn't fit on it.
I recommend you to get an external drive and store the files there instead of replacing the flash storage, which is expensive and will void warranty

Macbook pro with retina change keyboard

i wanna buy a macbook pro but i wanna Configure my MacBook Pro with the following keyboard language portuguese that is possible. tell me how i can do that and where i have to go buy it.

Nobody in these forums represents Apple or any store. To find out whether you can buy something, you need to contact the store or check their website directly yourself.
Sometimes an Apple retail store can make a special order for you.
http://www.apple.com/retail/
The Apple US online store tells you on its website which keyboard options are available.
When you contact a store, make sure you tell them whether you want Brazilian or European Portuguese, as they are not the same.
