17"MBP(2011) has no keyboard lights

Question saya it all. Please help.

There are some sensors, probably beyond the top edge of the keyboard, that are intended to turn on the keyboard lights when the light levels are low enough. Normally, the light levels do not require the keyboard lights, so they stay off.
There are also some configuartion options in System Preferences > Keyboard.

Upgraded to Maverick, now MBP 2011 has black screen while booting

I just upgraded from Mountain Lion to Maverick, and I am already regretting it. Upon installation, my MBP (2011) was running slow, so I restarted it. Now, when my Mac is trying to boot, the brightness is at (roughly) 25%, and I can barely see what's happening. It looks like the loading cursor is present onscreen. The good news is that I can hear the startup chime. However, after 10-15 seconds, the screen fades to black. When I press any key, I can hear the default error sound. I tried Command+R, but that didn't do anything. Any help would be greatly appreciated!

Not sure what happened. Upon the umpteenth time restarting the laptop, the scree is now at 100% brightness. I was able to log in as well. All is good.

Macbook pro 2011 has faint green light. won't turn on. what is the issue?

I've had this problem twice and both times I've gone to the genius bar they've plugged it in and pressed a few buttons and it's working fine. It's a 2011 macbook pro 13 inch. Has a faint green and flickering orange light on the charger. I've tried resetting the SMC and the basic troubleshooting steps. I'm tired of going to the genius bar for a 5 minute fix. I can't turn it back on after it suddenly shuts off. Power button is not responding. It was updated and working fine. Im a student and can't afford to have this problem every week. What is the issue?

Just face facts - if water (or any other liquid) reached you logic board or any other electronic components, you're going to be the victim of corrosion.
Eventually, you'll need to have the logic board replaced. There are liquid sensors all over your MBP and the techs can tell if these have been activated. I wouldn't turn the computer on at all - if it were me, I would take it to your local Apple Store/AASP and get an estimate for repair. Rice & other desiccates may 'dry up' the liquid, but it won't undo the damage already done.

Backlight keyboard issue (MBP 2011)

Well I installed Lion and my MBP 2011, brand new illuminates when starting up. It goes bright then dims down to the setting I have (off). It's annoying but how can you stop it from illuminating at start up. I tried a SMC reset for my intel MBP i7 computer. Any other suggestions?

Try System Preferences>Keyboard and UNCHECK 'Automatically illuminate keyboard in low light'.
Ciao.

Keyboard light doesn't work after updating to 10.8 on MBP

I have tried to update a MBP from Snow Leopard to Moutain Lion. But after updating the keyboard lights stopped working. Its A MBP from mid 2010 Core2, 2,4Ghz
We have tried to reset the smc.
Tried to untick the automatic brightness contoll of the keyboard llumination in system preferences.
Tried to use F5/F6 and it just shows that the keyboard light is turned on but its completly dark.
Is it coming a an mac os x 10.8 update for this problem?

Sounds like they did an Archive & Install, which leaves you with non-functioning Pro Apps (and Adobe apps, if you have any).
Try removing Final Cut Pro and Compressor and reinstall.

There is an application called FCS Remover, but I am not sure if it works with Final Cut Pro 4.
If it is still not working, I would try what David suggests.
Here is a list Jon Chappell has compiled about what versions of OS X, QuickTime and FCP works best together: http://www.digitalrebellion.com/blog/posts/recommendedquicktime_and_mac_os_configurations_for_final_cutpro.html
If you live close to an AppleStore you could try to bring it back and ask them to help you.
Best of luck!

MBP 2011 Screen brightness changing regardless of the ambient light

As stated in the subject my brand new MBP 2011 screen brightness changes on its own, yes i know about the ambient light sensor, but my screen is going from med brightness all the way to minimum brightness even though the ambient light is constant. yes I know i can turn it off, but why build in an ambient light feature that just makes the screen go to mimimum brightness when in a well lit room??
or do i have a faulty one??

I too have this problem on my spanking new MacBook Pro. Called AppleCare and they said they weren't aware of this issue.
Meanwhile, this is my 1st mac. Had it for a few weeks now. Decided to open iTunes for the 1st time. The whole MacBook Freezes, no mouse interactivity, reboot required. This happens EVERY time I start iTunes which I no longer do. Apparently it's a known issue which Apple has patched(unsuccessfully). But hey c'mon, I mean iTunes? This is one of the core apps which SHOULD be tested extensively against the hardware. When you consider Apple PROVIDES the hardware, this is simply unacceptable. Unbelievable even. I simply can't believe how poor this is from a major company. But hey my MacBook Pro LOOKS GOOD right, so who cares if it's a technically malfunctioning piece of junk.
Here's my theory. Is part of Apple's patch deliberately reducing screen brightness without user authorisation when the MacBook starts to overheat, all because they know they've been incompetent/negligent with their QA testing and the hardware can't handle the software? If so, why have users not been informed?
I'm from Australia and we have this so-so comedian called Chris Lily who fans have taken to calling a genius, the joke amongst non-fans being the word genius has been dumbed down over the years to be almost meaningless. Anyway, maybe a certified Apple 'genius' can explain the reasoning for the apparently deliberate brightness reductions?

MBP 2010 had Mobo replaced - Now keyboard lights not working?!?!

Hi,
I have just picked my MBP 2010 back up from the apple store, after it having its main logic board replaced. After having it back home for a few hours, I have only just noticed that the keyboard back lights are no longer functioning. By turning the brightness up with the f6 key, it brings up the HUD which shows the brightness bar going up, but the lights are still off.
I have tried to go into the settings and turn off the option that says automatically illuminate keyboard in low light to see if that fixed the issue, but no success. I have also installed lab tick, but this still did not get the backlight functioning.
The last thing I tried was a SMC reset. I performed this twice but to no avail.
I have tried to search the forums for alternative reasons as to why they would not be working, but cant find anything.
Can anyone advise me as to what my next step should be? I would like to try to fix this myself rather than take it back to the apple store, as it is about an hours drive away (last resort). I have read that there is a cable that connects the keyboard backlight, and this could become loose during maintenance. Is this easy to find / check ?
Thanks

Just incase people have the same issue down the line, I managed to fix this problem myself within 5 minutes.
I found a guide on ifixit.com for my model of macbook and then looked at the logic board replacement section (as this is what repair it had been to apple for).
I found the section regarding the power ribbon for the keyboard lights, and after taking my mac apart, I realised that they had not connected the ribbon, and it was still left unattached under one of the fans.
Carefully connecting this back and then putting the fan back solved the problem. So a simple 5 minute job has saved me a long trip back to see apple.
Thanks for your help anyway guys!

Has my macbook keyboard light? 13" Aluminnium late 2008

I don't know if my macbook has keyboard light...
It's a 13" Aluminnium late 2008. Somebody knows???

It might... the base 2.0 GHz model did not have a backlit keyboard. The 2.4 GHz model did have a backlit keyboard.

Do you have a 15" mid-2010? If so then your problem is surely...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,
Clinton

Problem with Battery and Keyboard Light

First off, sorry if this is in the wrong section. This is my first time on these forums.
Just today I was skyping my girlfriend on my Macbook Pro (that I got in the summer or 2010). I have SmcFanControl installed and I regularly use it to monitor/increase my fan speed. As I regularly skype and play WoW on this computer, my computer temp often sits around 160-170 degrees F.
Today it was at around 170 and I had it on my lap. I sat up and jostled the computer a little and it shut off. The power cord light, which was green, immediately turned off. I tried unplugging it and plugging it back in and it stayed off. The computer wouldnt restart for about 30 seconds. Finally after hitting the power button several times it turned on.
It worked fine for 10 or so minutes. I assumed I just moved it too suddenly, although I have never had a problem with that before. Then, I moved again and it shut off AGAIN. It took another 30 seconds to register the power cord and to turn on.
This time, when it booted up, it said my clock was set to a date before 2008, althought it was still at Feb 16, 2011. Also, as soon as I turned it on, the fans were going full speed (as loud as when i have SmcFanControl set at 6200 rpm). I opened SmcFancontrol and it says my computer's temp is at 32 Degrees F and 000 rpm, which I know is not correct. I can't change the speed of the fans and the temp of the computer hasnt changed at all.
Also, my battery icon has an X through it and says "No batteries available" "Power Source: Power Adapter." The green light is very dim on the charger.
AND on top of this, my keyboard lights no longer turn on, even pushing F5 and F6. I am in a dim room so they should auto turn on.
I am afraid that I may have overheated the computer, but I was wondering if anyone has any advice. I was thinking of opening the back up but I dont have a small enough screwdriver at the momment. I also tried doing the "top -u -s3" command to check cpu% and my highest one is Firefox around 10-15%.
Any help would be appreciated. I'm thinking this is gonna require a look at the Apple Store, however I am an out of state college student and I'm not returning home for another week and I need my computer for assignments.
Sorry for the wall of text. Thanks in advance.
P.S. My computer is up to date.

SMC reset works best with anything that relies on power for the machine. When it comes to batteries SMC reset and PRAM usually do the trick. Also a lot of people miss this, do not plug on the top plugs use the lower plug.
As for the temperature on the lap, expect a lot of heat, the computers are designed to lay on flat SOLID surfaces. The underbelly on aluminum chassis laptops act as a heatsink. In addition the rubber feet keep the product high enough so air can pass through and help cool the system.
As far as the adapter you can have AppleCare send you without waiting a week for it. If it is an obvious hardware problem they may do an exception for you if you are out of phone support. Highly recommend APP for the phone support. You would have a battery on it's way to your current location in a couple days!

After SMC reset, MBP 2011 with Yosemite OS cannot restart

My MBP 2011 which I recently upgraded the OS to Yosemite has been giving me endless problems when it restarts or reboots. when the power button is turned on, it starts up with an apple icon with a loading bar below it. The bar progress rather slowly and somewhere before reaching the halfway mark, the whole computer shuts down and restarts by itself. This process can actually go on for like 24 hours without a single break and the last experience I had was thaynir has been restarting and shutting down for the past 72 hours!!! Finally, I did a SMC reset by removing the battery cable, pressing the power button without the battery (5secs) and got the unibody assembled, plugged in the MagSafe and tried turning it on.
to my utter shock, after the SMC reset the MBP now cannot be turned on, no lights indicated at the MagSafe and it is completely dead. What do I do??? Please help folk!

You need to take it to your local Apple Store and have it checked by a Genius. Thats the best and safest option available to you now.
