MacBook Pro :: Disable Ambient Light Sensor (auto-dimming)?

Apr 28, 2007

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...

OS X :: Terminal Command To Disable Ambient Light Sensor?

Sep 16, 2010

My end goal is to create a script that will disable and enable the Ambient Light sensor when I plug and unplug my MacBook Pro from power.

To do this I'm pretty sure I need a terminal command to enable and disable automatic dimming as the ambient light changes.

MacBook Pro :: Ambient Light Sensor Is Too Sensitive?

May 12, 2010

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!

MacBook Pro :: Ambient Light Sensor Not Working?

May 16, 2010

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.

[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.

Do new ones have it? I have a 20" aluminum one as well, but don't see a sensor.

Way To Show Just Ambient Temperature Sensor Reading On An IMac?

May 12, 2012

Is there a very simple way to show just the ambient temperature sensor reading on an iMac? Not for geeky or engineering purposes. Just to know the temp that the machine and the human are in.iStat widget shows it but really tiny, buried in all the other data,and only if you launch Widgets.Ideally, it would just work in the background and the temperature would show up in the menu on the right side. Maybe next to the time. Alternatively, as a little floating window on the desktop.Yep, just want to see the room temperature using the iMac thermometer.

OS X :: MacBook Air Ambient Light Kernel Panic

Mar 19, 2010

A MacBook air that I just got up and running again after replacing the hinges along with the whole top half of the computer. I did a clean install of snow leopard, and was so happy to be using the air again.

After changing some settings and loading a couple off apps in my room with the lights off (so I could see the backlit keyboard), I flipped on the light switch in my room, and was immediatly shown the the kernel panic screen, and was forced to shut down.

I figured this was just a random occurance, so I booted back up, but was in kernel panic as soon as snow leopard booted. Went through this a couple more times, then shut the lights in my room back off, rebooted, and was able to boot up just fine. I then took a flashlight and ran the beam across the ambient light sensor, next to the camera, and was instantly in kernel panic again.

After saying WTF for a while I decided to swap the camera/ALS/mic board over from my old screen bc I figured maybe this new one is just bad. But this resulted in more of the same. I then did a new fresh and clean snowleopard install, but about 5 mins after finishing the install, it went right back to the good old kernel panic screen.

Now I don't really know where to go from here. The computer is way out of warranty, and after what I was quoted from my local apple repair store to repair the hinges and screen that I just fixed, I think I would just get nauseous at the thought of having to bring it to them now.

MacBook Pro :: Stop Laptop From Auto Dimming In Dark Rooms?

Jun 25, 2014

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.

PowerPC :: Ambient Light G5 2.0 Imac Shut Off?

Oct 28, 2009

So I've done all I can find on the internet on helping my broken computer. It used to have the noisy fan issue and then it would shut off. Now after being off for 12 hours, it may shut off in 2 minutes, maybe in 30. I have reset the SMU by unplugging for 10 seconds and then plugging in while simultaneously holding the power button, then turning it on. Ive also reset the PRAM, but it still seems to shut off. Is it a bad power supply? I dont ever hear the fans blowing hard anymore.

If anyone has basic things to do, I'm all ears. I know last step is probably just reinstall OSX.

I'm on 10.4 right now.

MacBook :: Motion Sensor Kills Back Light?

Mar 29, 2010

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.

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.

MacBook :: Location Of Macbook Keyboard Light Sensor?

Dec 22, 2008

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.

MacBook Pro :: How To Disable Auto Booting Into OS X

Sep 2, 2010

I got BootCamp setup with a Windows 7, however whenever I restart or turn on my MBP it automatically boots into Mac, and if I want to boot into windows i would have to hold on to the option/alt key at the start in order for me to choose which drive to boot from. So my question is whether there is a way so that every time I turn on the MBP it would automatically show up the 2 OSes for me to choose from?

OS X :: Disable Auto Mounting Of Selected Volumes?

Aug 30, 2009

I have a number of volumes on my computer and assorted drives, some of which I use very rarely, and I'd like to keep these from being mounted automatically, just to reduce the clutter in my sidebar.

Years ago there was a method of disabling the auto-mount feature of certain volumes, but I haven't the vaguest idea of how to do it now -- if in fact it can be done.

I've ordered Snow Leopard, but am still using 10.5.8 on a Mac Pro.

OS X V10.6 Snow Leopard :: How To Disable The Auto-eject Of A Failing HD

Mar 31, 2012

My kids HD just started to fail.  Apple replaced it this AM, however my kid's TM backup is about 5 months old.  I am trying to recover the data from the old disk. 

She put the old disk into an enclosure and connected it to her MBP.  As I try to copy as much of the drive as possible it gets an error, ejects, then reconnects and give an annoying message that I didn’t eject properly.  This is making it very difficult to get all the data off. 

I figured if I mounted read-only that it’d stop doing that, but it does not.  I’ve run fsck, etc… 

All I need is for this stupid machine to log errors and move on just like single user mode.  However, I cannot use single user mode because I am 2000 miles away from the machine.  And using Facetime to remote control my kid has pushed me to the edge.  There has to be a way to make OSX as “unfriendly” as Linux. OSX needs a “pro” mode. 

So, I ask again.  How do I stop OSX from auto ejecting a disk when it errors?

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...

MacBook Pro :: Screen Is Dimming And Brightening Quickly?

Aug 26, 2010

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.
