MacBook Pro :: Screen Keeps Dimming Automatically?
May 28, 2012
My brand new Macbook Pro's screen keeps dimming the screen all the time regardless of which setting is it on. Its the first time it does that today and it's so annoying!I have the following options: Put the hard disks to sleep when possible, slightly dim the display when using this power source, automatically reduce brightness before display goes to sleep and restart automatically if the computer freezes. The only thing that is check marked is Put the hard disks to sleep when possible and automatically reduce brightness before display goes to sleep...

I just got a brand new MBP (6,2 and 10.6.4) but it's not my first. My previous MBP had the ambient light sensor that I could turn on and off via the system preferences (as mentioned in this thread) so suffice it to say, I know what it looks like when the screen dims and brightens. (I loved hovering my hands over the speakers. It was like magic to my PC friends.)
Now, I'm having an issue with my new MBP. I have my preferences set to adjust the brightness based on ambient light. And since the light sensor has moved to the microphone, it still does that just fine.
My problem is that I'm experiencing random flashes of the screen where it dims quite a bit rapidly but only for a short moment before returning to the original brightness. This occurs randomly in different light settings but most importantly when the light around me hasn't changed at all. And it has occured about once or twice a day for the last few days. I've even tried pressing my thumb over the light sensor really fast to see if it was the light sensor but try that and you'll see that it's actually really slow.
My other problem is that my screen is randomly resizing/zooming in on things. (I suspect this may be me doing some trackpad trick I'm unaware of but I've tried everything I can think of to replicate it and nothing works) Anyways, say I'm on my desktop and mousing over (with one finger) to open a folder or file. All of a sudden, all of the folders resize drastically. Or I'm in Firefox and a site loads. Then all of a sudden (*insert poltergeist*) the website zooms in or out. (like when you press cmd + or -) And it's always zooming in, never out.
Does anyone know what is going on with this? I don't know if the two things are related or if all of this is just really really stupid user error.

I've discovered that if I am reading a book or have my hand up in the line of the camera and the 'sun' or 'light' the screen goes dimmer, but if I move it away the screen gets brighter. It's quite frustrating! How do I stop it? In system preferences, in enregy saver, I have unchecked the '

I encountered a problem this evening with my Powerbook G4 15 inch Powerbook. When I was opening the Powerbook, awakening it from sleep it seemed there seemed to be an abnormally bright flash, then the screen went almost completely blank. Luckily, I was able to see enough to burn my docs to a disc in the event this was a serious problem. It seemed the rest of the laptop was fine.
When I restarted the computer, the screen appeared to be fine. I ran Onyx in the event it could clean anything up, and when it was running the screen appeared to go attempt to go to sleep again (although it was not set). Touching the trackpad immediately woke it up without a problem. After restarting after Onyx finished and using it for about a half hour I have not encountered the problem since.
Is this a sign of a failing LCD or possibly a bigger problem or just a harmless isolated event? Is it worth trekking over to the Applestore? I'm covered under Applecare.

when I cover the sensors at either side of the keyboard. This happens a lot when I am typing at it really bugs me. I think I managed to turn it off before but it has started again and I can't remember what I did.

I'm having a brain fart, but since I've installed 10.6, if I don't touch my mouse for 1 minute or so, the screen dims. It didn't use to do this before, and I'll be damned if I can figure out how to fix it. My cord is plugged in, and under energy settings I can't see anything related to this...how do I fix this? Is it acting as though I am running off of battery power, and dimming after a minute. I even changed the settings to NOT dim, even on battery power.On another topic, this update actually cost Apple money, because I was planning on buying a new MacBook Pro, but I zeroed out the hard drive and did a clean install, and my old Mac is so fast now, it is as if I DO have a new MacBook!

I'm experiencing a problem with my monitor on my 1.67 GHz PowerPC G4 recently. A few weeks ago the monitor would dim when extended past parallel. Now It dims past 30 degrees. It seems to be getting worse by the day. Anybody have any ideas why this is happening, and more importantly; how to fix it? By the way, I don't know much about the insides of these things.

Just recently I purchased a MacBook Air 13'' (1.7 GHz, 4GB, 256GB) with Lion installed in it and I have got an external monitor attached to it. It's been working really well for a couple of weeks, but in the last couple of days I have noticed how my browser windows, and only those!, for either FireFox, Chrome or Safari, keep dimming themselves while I am on other windows from other applications as if they were inactive, when they are not, because I am using the Mac still. And I can only get them to work again, i.e. loading Web sites, only after I click on them to activate them, which is annoying, because I may be on another window, would need to click on a link and it won't load on the browser window till I have clicked on it, on the browser window, that is.
I have searched in Google and found a couple of articles where it was highlighted how the problem may well be with the Settings under "Energy Saver" and I have got unticked in there for "Slightly dim the display when using this power source" and "Automatically reduce brightness before display goes to sleep" and still the same problem. Other articles suggested that I would try Caffeine and install it to get rid of the dimming of the screen, but even after installing I still have got the issues and I am, at this point, running out of ideas.

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...

My computer has recently started auto dimming when in darker rooms of the house, i know its an issue with the light sensor because I've held a flashlight to it and it instantly brightens, however, i have unchecked the "automatically adjust brightness" box in the system settings and it continues to dim it's self even when unchecked and brightness is on full. It isn't the result of any recent updates, as there haven't been any in some time and it's only started in the last two weeks.

I'm pretty new to OS X, having just got my MBP 15" 2010 model.
I use my laptop with a external monitor for music production, and when I use a particular piece of software, I like to have it on my (bigger) external display. I'm wondering if there's any way (using Automator possibly?) to set the menu bar to switch screens automatically when I open this program?

I use Google Chrome for my web browser and lately whenever I open a pop-up window it automatically goes into full-screen. I don't remember changing any settings and can't figure out how to change it back. What did I do?

So I have noticed a few times already, that the screen on my white macbook flickers to change the brightness level. It can do this while the computer is plugged in and charging, or if it's off the charger. It is definitely noticeable as it causes me to just watch what the screen is doing.

I got a fairly new macbook 13, the last model before the firewire. I notice something very weird. The screen brightness changes. At first I thought I am imagining or maybe its like LCD's where color and brightness changes from one angle to the other but that is not the case...
If i come closer to the screen it takes a bit then it lowers the brightness, if I go further it does the opposite. If I adjust the screen it happens too, and I notice it happens a lot more if I am sitting in a darker room that a bright room.
I can almost swear the isight it doing some adjusting by its own calculating my distance from the screen. These are LEDs I believe. Any one heard of such a thing? What is this? Sometimes to happens while I am reading an article without moving.

I reset my PRAM yesterday to fix some issues with videos being choppy. It has helped somewhat in that regard, but I've noticed a new issue with my display becoming dimmed. I have my screen saver set to kick on after 5 minutes of inactivity. My display is set to turn off after 15 mins. My display is dimming, however, after 2 minutes of inactivity? It's very frustrating, and is actually causing me headaches because of the differences in brightness.

Does anyone know if it's possible to dim my late 2008 macbook's display more then the lowest setting allows? It seems way too bright in the dark even at the lowest setting, plus I would like to save more battery if possible.

My G5 has developed a problem with restarting. Basically if I restart it gets to the grey screen with the apple logo and the spinning thing but shuts down as soon as it gets to the blue screen. This will happen for as many times as I care to restart it. The only solution I have come across is to take out the SDRAM modules and swap them round (any combination will do as long as they are swapped) and bingo, it starts again as if nothing was wrong.
Initially I had four 512k modules from Crucial and recently replaced them with two 1024 modules from another manufacturer to see if that would solve it but it didn't. Zapping the PRAM also didn't work. I should say also that around the same time it developed a habit of shutting down mid-use, but this was solved by switching the processor usage from high to automatic.

Is there a shortcut in Mac OS X that resizes two or more open windows automatically so that each window is shown on the screen simultaneously? For example, I want to have a safari window open and a word document open so that one half of the screen is showing safari and the other half is word. I know I can resize them manually but I was wondering if there is a shortcut or a third party utility that resizes any open windows to fit the entire screen? This would be useful, for example, with the new 27 inch iMacs where the wide screen can easily display three (or more) windows side by side utilizing the entire screen area; having them resized automatically would be more productive than having to resize them manually.

For two weeks my screen will go blue and then any data on the screen will come back, either to normal or expanded in scale. In the desktop preferences it will offer desktop and VGA options. Over the last two days it will resize smaller with black edges and display the last wallpaper I used not the current one. Any help in correcting this would be great it's an iMac and runs Mac OSX Version 10.4.11

So this is the message I'm getting every time I boot up my new MBP. I can't get past it unless I hold the power button to kill it then hold option when I power it back up. Once I do this I get an OSX hard disc image that I have to click on. It started doing this when I started to install Windows and had to quit before I finished. How do I get it to automatically boot to OSX?
