Program to automatically adjust brightness dependent on power source?

I just bought a MacBook Pro and would love to have my screen brightness adjust automatically based on whether or not the machine is plugged in. I find that the first thing I do when I plug it in or unplug it is adjust the brightness. I like the screen at full brightness when it is plugged in but on a lower setting when running on battery power.
You would think that the Energy System Preference would include these settings. Does anyone out there know of such a beast???
Thanks,
Frank

It's in the Energy Saver Preference - battery then
click options - there is a box.
I am aware of that setting: "Redcue the brightness of the built-in display when using this power source"
However, what I am looking for is something that will allow me to specify EXACTLY how bright I want the display to be when it is plugged in and how bright I want it to be when it is not plugged in. The checkbox provided in the Energy Saver preference does not give me any control. How much is it reducing it? What if I had already manually set it low? Will it reduce it further? The checkbox is basically useless.
Thanks anyway,
Frank

How do I turn off "Automatically adjust brightness" on Mountain Lion using AppleScript

I'm new to Mac, Applescript and Automator and I'm trying to make a automation for when I perform on stage and found a script to set the brightness all the way up but can't find a script to disable "Automatically adjust brightness". Any help would be appreicated.

You could even both “set the brightness all the way up” and “disable Automatically adjust brightness” with just one and the same script:
tell application "System Preferences"
    -- launch
    -- activate
    set current pane to pane id "com.apple.preference.displays"
    reveal anchor "displaysDisplayTab" of current pane
    tell application "System Events"
        tell process "System Preferences"
            tell group 1 of tab group 1 of window 1
                set value of slider 1 to 1.0 -- max
                tell checkbox 1
                    if value is 1 then click
                end tell
            end tell
        end tell
    end tell
    quit -- optional
end tell

Automatically adjust brightness way too aggressive

I've noticed in low light situations, my new MacBook is almost constantly adjusting the screen and keyboard brightness. It's highly distracting. I've got around the problem by simply turning off "Automatically adjust brightness as ambient light changes" in Displays, but I'd like to know if anyone else has this problem.
If it's unique to mine, I should probably get it fixed...

It is just how things are. However, some sort of software fix could probably improve it! I own another monitor with a light-sensor, and these just seem to be sensitive, especially in low light.
Take in considerations that it monitors the light continuously. If you are in a dark room, you will be lit by the display. So if you move around, the amount of light on you (and thereby the amount of light sensed by the sensor) will change. Resulting in some weird behavior.
So as you figured out yourself, turning it off gets the best result. Luckily it is easy to change the backlight of the display and keyboard.

Automatically adjust brightness - Missing

I have a user complaining of the brightness level changing continuously. I researched and identified Automatically adjust brightness needed to be disabled. When I went to disable it, I found it was missing. I researched that, but couldn't find anything about that. I did find that older iMac models wouldn't have that feature, but we purchased this hardware last year. Is that too old? Anyone have any ideas?
- OS X version: 10.9.4 (13E28)
- iMac 27-inch , Late 2013
- NVIDIA GeForce GT 755M 1024 MB

Where did you look to disable the feature. It's in the System/Displays/Display preference pane:
If the checkbox is not there Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair disk permissions and the disk. Reboot normally and try again If that fails reboot into the Recovery volume again and reinstall the system.

This circuit has no power sources: unable to determine the simulation timestep automatically. Please add a power source or set the simulation timestep under "Interactive Simulation Settings" to proceed.

Hi again.
I built this circuit but I keep getting the error message in the title. I have gone through the older threads on it but can find nothing to help. If I run the digital smaples they work fine. If I run other digital circuits I made they work fine. I have tried this circuit on another PC and get the same error.
Any help would be greatly appreciated.

Display Auto adjust brightness acting weird and flickering

Last couple of months I get a fair amount of flickering on my screen. As far as I can tell, there
is no specific area that it is flickering in. After checking my settings for Auto brightness,, I find that
the box that is there for ticking off "Automatically adjust brightness" is unticked, and the brightness is
moved to around the 3/4 brightness area. I am in my basement which is fairly dark, so basically I am
trying to find out about the flickering that goes on, and have a feeling that when the brightness is diminished, it
causes/caused the flickering. So, I raised the brightness to extreme(right to the end of the scale) and continue
to have the box "Automatically adjust brightness" UNCHECKED. Sooner or later,, something must trip off the
Autobrightness,, because I eventually notice the flickering going on,, then I go to my settings to check the brightness,
and find that the slider is back to 3/4 and still the Autobrightness box is Unchecked. This happens all by itself.
Basically , #1,, whether it is on Auto or Not,, I shouldn't get any flickering, and #2,, my display shouldn't on its own
adjusting automatically the brightness by itself, unless I check the box correct? How can I get my screen brightness
to stick ?

To close out my original post, I never did managed to solve my flickering problem. I did every trick in the book, including SMC resetting PRAM etc. So, just as I had given up trying to fix, low and behold, my left side of the
screen one fine morning became rather dim. I knew that something , like backlight had gone on it. So, I still had
lots of warranty, brought it in. This time, because of it being a rather obvious defect upon looking at my screen.
The genius ordered a new LCD and backlight .
So far, no flickering, however, I still have the brightness level that drops down from a full brightness, no matter if I check off "automatically adjust brightness" or not. This being in a relatively dark environment.
I can imagine that there are many people still with this problem, with no obvious solutions that are 100 % effective.

(SOLVED) Display brightness disappeared from Power Options in Vista, Lenovo G530

Hello board,
My system Lenovo G530 product ID 444638U
I used to be able to adjust display brightness in Vista from Control Panel > Power Options. I could set how bright when on battery and how bright when on AC. Also, it used to be that when I unplugged power cable it would automatically adjust my brightness according to those settings. Now, nothing happens when I unplug power cable, not even a beep.
Possible problem is as follows, but let's keep an open mind to other things as well. I spilled beer on keyboard recently. ONLY on keyboard I am sure. I replaced keyboard with something that fits but something that isn't made for my laptop, has different arrangement of Fn+ keys. Basically ever since the beer accident and ever since I replaced keyboard I had this brightness issue.
Please help me solve this.

Solved!

I solved this problem..
Solution is to upgrade the BIOS to latest version. I am not sure actually whether latest BIOS had the needed fix or not, or it was just the process of updating the BIOS that solved this issue. But no doubt, after flashing the BIOS, display brightness function reappeared!

Windows 8.1 Bootcamp wont Sleep or adjust Brightness

Hey Guys, I installed windows 8.1 via bootcamp onto my 2013 rMBP, 16gig Ram, Upgraded Processor, and I have two issues with it. 1. I cannot adjust my screen brightness, which is manageable but annoying. 2. It wont go to sleep. There isnt an option anywhere to adjust brightness or put it to sleep. The only option are to hibernate, shut down, or do nothing. It seems as though the sleep function just isnt available, nor is the brightness. I feel like thse two things may be connected, but I wasnt sure. I have browsed some threads, but nobody seems to have a find for 8.1 or these problems yet. When I try to sleep my computer (i.e. close the lid) it just shuts down, and I have to hold option to power up back into windows. If anyone has a solution, please do let me know:) Thanks!! Also I'm running mavericks fully updated, the newest bootcamp software and the newest bootcamp drivers, AND windows is fully updated.

I have the same issue. Any luck miller? When I close the lid on my Macbook, i have to power back up and use the OPTION key to get back to Windows 8.1. This issue just started after updating to Mavericks...
My brightness control does work fine.

Trouble adjusting brightness in Windows 8.1

I know there are other threads on this, but none of the solutions seems to be working for me.
I manage multiple MBP-13in Retinas (Late 2013) and I'm having trouble adjusting the brightness of the laptop screen on all of them.
I have tried everything mentioned in other posts
Adaptive Brightnss
Disabling the Generic PnP driver
Reinstalling everything
Changing the resolution
The best work around I can figure out is hitting Comman + P (Windows Key + P) switching the display mode to extend (or anything else) and then switching it back to PC Display only. After doing that it works everytime.
It also seems to finally work if I leave the computer on for about 15 mins or so, or if I shut the lid and then open it back up again.
Would love a new release of BootCamp to fix this, any work arounds that people have discovered specifically for the 13in MBPr Late 2013 would be greatly appreciated.
Thanks!

Clean install 8.1 via boot camp
We make a few consistent changes but I can't imagine these are related but here's a full list
Disable hibernation, page file, adaptive brightness, system restore
Power settings never sleep while plugged
On display settings, try for best performance it will likely uncheck everything (we keep 5 but can't recall)

F.13 is a standard program for automatic clearing?

f.13 is a standard program for automatic clearing? can i include plant code to the standard program.....and it is used for display clearing......need information?

HI,
F.13 is a Stanndard program for Automatic clearing as you rightly siad. This is wholely dependent on the settings that you make in OB74 which is matching criteria.
Let me take an examloe and explain.
Lets say you have a customer invoice for 1,00,000/-. The customer has given 80,000/- once and 15,000/- once and the balance 5,000/- the company has issued a Credit Note.
If this is a single transaction in a year you may wonder why this F.13 is used. However in practice there will be many transactions per day it self and advising a business proces of F-32 account Clear is not a good practice as the user is loaded with transactions.
Hence You will be taking this as a periodic process and clearing automatically is advised using F.13.
For the system to understand you will be giving the matching criteria in OB74.
So when ever you run this program, program checks for matching Amounts in Dr and Cr sides with the matching feilds given in OB74
The uncleared items need attention which may or may not be processed manually,
For GR IR clearing also you can use this transaction and any open item manged account as longas the matching criteria is confiured.
I don't think you can use Plant code in this.
Reward points if useful.

Auto adjust brightness ... can it be reversed?

I cant remember if i had this problem with Snow Leopard. Not sure if this is a Lion issue or my new MBA either.
The auto adjust brightness seems to adjust the screen brightness to low in bright light and high in low light.
I would like it reversed as in the dark, i dont need a bright screen and in the day, i need the screen to be brighter.
Any body noticed this same adjustment on their Lion MBA?
If so, does any one know how to reverse it?
Thanks

SAP has a program to reverse depreciation but it is somewhat complex and not available on OSS. I'm also not sure if it is limited to (or can be ported if it is) to the older depreciation program RABUCH which would limit it to those customers that currently post using RAPOST2000.
But barring access to the program, it's not possible to reverse it. You would have to proceed as Jagdish describes... feed the GL data that is -1 of the data that was posted. I wouldn't do it, personally.

Automatic display brightness not working on 2012 Air?

I have a 2008 aluminum MacBook which I bought on day zero. The automatic screen brightness on it works perfectly. When I am in a dark room, the brightness goes down significantly, so I am not blinded. When I am in a bright room, the brightness goes up. The keyboard backlighting is equally consistent and works great. It's all worked perfectly for the past four years.
I now have a 2012 Air and the automatic brightness doesn't seem to work as well. It barely seems to change the brightness. I use it in a pitch black room and the brightness goes down a bit, but no where near as low as on my MacBook. I have to manually turn it down further. Another example: I had it turned down last night, but right now, typing in a sunny room, the brightness has barely raised (when I push the brightness button, it shows it at four bars).
I never notice the keyboard backlight change. It also never seems to turn off, even when I am in direct sunlight. On my MacBook, it turns off in bright light.
I know the sensor is working, at least partly, because if I am in a bright room, I can cover the sensor with my finger and the screen dims a little.
Is this the expected behaviour? Does the keyboard backlighting never turn off automatically? Is your screen dimming enough in the dark? I literally never, ever, had the need to manually adjust my screen or keyboard brightness on my MacBook. On this new Air, the automatic brightness may as well be disabled, since it barely seems to do anything.

I think I have discovered the problem. The system remembers where you have manually set the brightness, and tries to stay around that level even when moving from bright to dark rooms.
I manually set the brightness to 5/8, waited a minute, then went outside in the sun. As expected, it adjusted to max. However, when I came back inside and sat down, it only went down to 5/8 again. I guess earlier when it was going down to 3/8, it was just trying to get back to my manual setting (I had set it to 3/8 this morning while in my dark bedroom). Even if I completely cover the sensor, the brightness now only goes down to about 4/8.
On the MacBook, it used the full range of brightness and completely ignored any previous manual settings. I could use the automatic feature to completely control the brightness at all times. Now, with the Air, the automatic feature instead tries to maintain the user-selected brightness level as much as possible.
I'm not sure which style I prefer. I did like not having to ever touch the brightness buttons, although I admit it was occasionally too dim in certain situations. I would prefer that the Air dim much more when in completely dark rooms, and maybe the sensitivity of the sensor should be increased a bit.
Now the only issue is how the keyboard backlight seems to stay on in all conditions except in the sun! It is on now even though it is obviously bright enough in the room to read a paperback book, let alone a keyboard.

Program to change screen brightness?

Does anyone know of a program that will lower the screen brightness beyond that available of the second lowest bright level (ie not the no backlight at all option) pre-set on the mac? I find the screen is quite bright at this setting, and would be willing to go even darker to save some battery power...

Not an answer to your question, but anyway:
System Preferences, Display shows a slider to set the brightness. Though this seems to be a linear slider, setting it between two discrete values (such as set using the fn-F1 and f1-F2 keys) does not actually seem to give a different brightness.
Furthermore, for battery usage the Energy Saver options include "Reduce the brightness of the built-in display when using this power source". This option in fact only works when the normal brightness is at least twice the minimum value. When the normal brightness for AC power is set to its minimum then unplugging AC power does not reduce the brightness any further.
So: I doubt you'll find the program you're looking for.
By the way: did you compare the brightness of your screen to other MacBooks? On my MacBook less than the lowest brightness would hardly be sufficient unless working in a room with candlelight

T440p screen slightly adjusting brightness on google chrome

Hi, my T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.
Solved!
