MacBook Pro :: Light Sensor Turns Up Brightness Of The Backlit Keyboard
Apr 29, 2010
So I've recently purchased the new 13" MBP, and to my understanding, there is a light sensor that turns up the brightness of the backlit keyboard and screen when in dark environments.
However, the problem with my MBP is that when I turn on the lights in my room, the screen brightness and backlit keyboard both turn brighter, and when I turn off the lights, the screen and keyboard grow dimmer, which is exactly the opposite of what is supposed to happen.

I thought Apple said that the brightness will go brighter when it's darker, and get dimmer when it's brighter. Why is mine doing the opposite?

I have 'Illuminate Keyboard in Low Light Conditions' Checked in system preferences and the keyboard is still lit up when the room is fully lit? Wouldn't only light up when the room is dark? I'm pressing keys and its always lighting up? its probably not even an issue and I'm over thinking it?

was wondering, where the keyboard light sensor was. It is strange because although my light sensor seems to be working properly, the angle of the screen can cause the sensor to be activated sometimes in indirect lightening situations. I just was wondering where the sensor was.

I bought my first Mac computer last month, the 13" 2.4 variant. Loving it so far.I have lately noticed however that my ambient light sensor is not much of help. Before, after coming out of sleep I could notice the screen changing to accommodate for the room's light output. I could also put my hand over the sensor near the iSight and witness the brightness decrease in front of me.

I've been using my mum's MPB C2D quite a bit, in anticipation of my own i5 arriving, and one thing that gets on my nerves is the ambient light sensor. It seems to be really sensitive, to the point where it will change the screen brightness when there has been no real changes in ambient light. If you move your hand over the sensor at the top of the screen, or even if someone walks past and casts a shadow it can change for a few seconds. Also, just moving the laptop around and the sensor changes the screen.
Obviously this setting can be turned off, but I'd like the feature if it wasn't so sensitive. Other than that, I love the MBP and can't wait for mine!

As of today, I noticed my ambient light sensor doesnt seem to work. I tried disabling and re-enabling it in system preferences, but that hasn't done the trick.
Is there some test I can do to see if it's working or not? I know it worked two days ago, because i took the i7 15" MBP outside and it automatically switched to max brightness. Today I took it outside and the brightness didn't switch at all and I couldn't see the screen it was so dark.
Since the last time it definitely worked, all I've done is install Windows 7 64-bit with Boot Camp and hooked up the MBP to an external 20" monitor with a minidisplay-DVI adapter.

I've had this new '13 rMBP for a little over 2 weeks now, and I absolutely love it! One small problem though, the ambient light sensor seems to not be responding, at all???

Here's a new one (for me anyway).
2007 MacBook: 2.16 Ghz, 3GB RAM, Intel GMA etc.
Anyway, all of sudden, any motion I make kills the backlight of the screen. In the right light you can still see things and the computer still works perfectly, just extremely hard to see. Have to do a restart in order to get going again.

I've noticed that the ambient light sensor in the MBP can be somewhat sensitive. Sometimes an action as simple as moving my hands up to the keyboard (from the side) triggers the "auto-dimming" feature of the screen and it slightly reduces the brightness of the screen, then quickly returns. This is rather bothersome.
I've got the option under Keyboard and Mouse "Illuminate keyboard under low-light conditions" unchecked, but the screen still dims if you cover the speakers. I've also got the option under Energy Saver "Automatically reduce the brightness of the display before sleep" unchecked as well.
I'm at a loss here. Is there not a way to disable this auto-dim feature? A Google search didn't turn up much of anything. Surely there must be a way...

This is a strange issue I have had with my Macbook Pro for a while now. Whenever I am in a situation where I am only using my computer for say, listening to music purposes, I like to turn the brightness all the way down. Whenever I turn the brightness all the way down, however, after a few minutes it will go back up 1 pip of brightness on its own. Once I come into contact with the trackpad, however, it goes back down. Then it will go back up 1 pip on it's own again, and go back down when I touch the trackpad. It continues to do this and it's quite annoying.

[URL] I went here. I have found out the iMac is a 2nd gen iMac G5. It has an ambient light sensor. I put my hand over it and it doesn't appear to actually do anything.
What is it supposed to do?
Do new ones have it? I have a 20" aluminum one as well, but don't see a sensor.

I am considering whether or not I will get the backlit keyboard model or not. I want to save $300, but I also want to be able to see the keys (within reason).
I like my current PBG4's backlit keyboard, and sometimes find it necessary, however, it does have low contrast silver keys with white lettering. Since the Macbooks have black keys with white lettering, and therefore more contrast, I am wondering if this will improve visibility in low light conditions enough so I won't have to have the backlight.
Do any of you have the new MacBook sans backlit keyboard, and if so what are your impressions of being able to see the keys in a dim (not dark) room?

I went to the apple store the other day to see if the top case of my (late 2008) MacBook's top case could be replaced (due to some sort of discoloration in the metal). Anyway, they are replacing it free of charge, but i was just wondering if i could tell them to use the top case of the 2.4 GHz MacBook (I have the 2.0 GHz, doesn't include backlit keyboard). I realllllllly want this backlit keyboard, and a replacement by myself is totally out of the question. Please help, i really need a shiny keyboard

I would believe having your backlit keyboard on max would kill the life span of the led lights? curious to know if anyone has it on max majority of the time to have the laptop look fancier rather then those who use the backlit accordingly to prolong its life time.
But in the cases for those who do set the backlit keyboard on max for a long time (speaking of months, even years) any issues with it? any led lights or keys breaking or stopped working?

I have a MBP on OS X version 10.6.8, the mid-2009 model. The problem: I can't get my keyboard to light up. When I press on the F5 and F6 button I see the image of the keyboard light pop up on the screen but it has a line through it telling me I can't do it. These feature worked a couple days ago, and I didn't change any settings since then. I have tried everything. I made sure the settings were right and reset them. I have tried to update my software which told me I was up to date. I have put my laptop in a pitch black room. I have covered the sensors. I have done an SMC reset as well as a PRAM reset. None of these things worked. I did download the LabTick app, which then I was able to light up my keyboard but I don't want to have to use a 3rd party application. I would like to have my keyboard adjust automatically. I have uninstalled LabTick.

When I turn my brightness all the way down, there's still a barely (but clear, still) lit circle at the centre of my screen. I have a 13'' mbp. I can even see my cursor and move it around. This spot, at very low screen brightness, appears kind of yellowish. When I turn the brightness up, it is not noticeable. The circle part has roughly a two inch diameter.
I've had the mbp for about a month, and just noticed this now. I do turn my brightness down quite a bit, but its usually in a well lit classroom and thus its possible I just did not notice this circle that is still barely lit until now.
UPDATE*: I have just discovered that covering the lit apple logo on the screen's exterior (directly opposite the lit circle i suppose) causing the circle to gradually disappear. THe laptop is sitting behind a window (ie light can shine on that apple logo)...what's up with this?

I have a 3 months old MBP SR and recently I have noticed that the charge light on the magsafe adapter turns off after a while. It used to stay green when the laptop was charged but now it turns off. It usually happens when I put the computer to sleep. After a while the charger light turns off. Not a huge issue but I was wondering if other people were seeing something similar and if there was something I could do to get the light back on (I think it looks nice).

System: Silver Macbook
OS X Ver.: Leopard
Backlit Keyboard?: No
Essentially my problem is that I'm unable to set new shortcuts for the F5 and F6 keys for my Silver Macbook. Since it doesn't have a backlit keyboard, there's no function for F5 and F6. I'd like to make them go to shortcuts such as "Show Desktop" and "Spaces", both of which are supported under the "Keyboard Shortcuts" Tab of "Keyboard & Mouse". So, I have them configured to match up to F5 and F6, but they do not activate the corresponding function when pressed.
I have the "Use function keys as standard function keys" checkmark unset:I apologize for the fairly small problem...I just really want to free up those two keys! I appreciate any response.

I was recently using my backlit keyboard of pretty much the first time and I realized that middle right side of the keyboard is slightly dimmer that the other side. I can still see the keys and its not a huge difference but its enough to be noticeable and somewhat distracting.

I just recently upgraded my 2010 macbook pro RAM. I went from 4gb to 6gb and now my backlit keyboard is no longer working. I have tried messing with the keyboard settings as well as the F5 and F6 buttons. The keyboard does not even come on in low lit conditions. Why is my backlit keyboard no longer working?
