OS X :: Display Dimming For 2 Minutes Of Inactivity
Feb 5, 2009
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.

If I am reading a page, for example, and I do not touch the mouse or the keyboard, the display turns off after approximately two minutes no matter what the setting is for the power savings feature.

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.

I've got a white macbook 2.16 I believe. The screen/display will turn on when booted up, but only stay on a few minutes. I got it off craigslist this way. When I first got it, it wouldn't come on at all. I replaced the inverter with one I got off ebay that was probably used. I have tried 4 different inverters in it (all used I think) they all respond the same way. Screen comes on for just a few minutes then the light goes black. If I disconnect the power to the inverter after it shuts off, then reconnect it, it will light up again for a couple seconds only. If I leave it alone, it will come back on after about 20 minutes.
Does this sound like I have a bunch of bad inverters, or a bad lcd screen? It also drives an external monitor flawlessly the whole time and keeps an image displayed on the screen even when the light dies.

I have my 09 mini connected to a Dell E177FP and I have the energy preferences set to turn the display off after 15 minutes. The problem is that the display never turns off. It just sits at the "check signal" screen as if it was not plugged into anything. How can I get the monitor to go into standby mode?

Noticed that my new MBP with 10.6.1 wasn't going to "sleep" after the time specified in System Preferences -> Energy Saver -> Computer Sleep. Closing the lid or choosing 'sleep' from the apple menu worked fine. After playing with it a while, I _think_ I might have narrowed down the issue:
First, a couple of questions to see if the problem I'm seeing is only my own, or a common issue.
If you are having the problem, is your MBP unibody? with SD slot or expresscard slot?
Are you using the Apple factory HDD or an aftermarket one?
How I fixed the issue: I had the option selected on the same preference pane to "Put the hard disk to sleep when possible." If I unchecked this item, the machine would sleep after the specified time of inactivity (Actually, it would take about 30 seconds longer while the machine wrote the memory contents to the HDD.)
If you had the problem, does this fix it for you? If you did NOT have the problem, does checking this box create the problem for you?

I have a C2D iMac about 3 years old, with 10.6 and all the updates. I have it set to go to sleep after 30 minutes of inactivity. Sometimes at night I will use it to listen to a podcast or watch a TV show. When I do this, it never goes to sleep. It's always still on when I wake up. The display will sleep, but not the computer. I can put the computer to sleep myself through the Apple menu, but it never sleeps due to inactivity.
I'm worried that having the computer on 8 hours a night due to this problem will shorten its lifespan. Does anyone have an idea of what may be causing it? Does it have something to do with webpages being open? I always have Safari open. It's easier to leave pages open than it is to go through dialog boxes and menus to create and delete bookmarks all the time.

I can get Mavericks 10.9.3 working again now after freezing constantly but now it seems to freeze after being inactive or when I stop to go do something. This MacBook Pro worked fine before upgrade.

Lately I'm starting to notice that if I leave my Macbook just sitting there for awhile, when I return to it, it didn't go to sleep, but it rather logged me out, leaving me at the login screen. I then have to re log in and re-open everything I was working on.

Recently I am having issues with the screensaver setting, it comes on every time I reach the log-in page while booting, and instead of turning on after 'x' minutes of inactivity it just gets turned on after 'x' minutes. Means if I slide it to 5 minutes, I get the screensaver on after 5 mins, be it doing work or watching a movie in it.

After just over one minute of inactivity (no moving mouse, typing, etc.), I get a "Logout, Cancel, Restart, Shutdown" screen. If I don't quickly click out of it, the computer totally shuts down. I have an Intel Macbook. I don't believe it's a hardware problem; I've run the hardware test and it comes up clear.

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.

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'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!

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.

Since recently updating Safari to 5.1.5, I can no longer access my online class. I AM able to log into my account, but when I click the link to enter my classroom I receive the following error: There is a problem with your authentication, possibly due to inactivity. For your safety, you have been logged out and must sign in again to continue.
I have thoroughly researched this issue. I attempted to delete all website data, deleted the cache, reset Safari. I have not had success with all of these attempted fix actions. I am NOT interested in reinstalling Lion--NOT happening. I am able to access from Firefox on my Mac, my work computer, my iPhone, my iPad, and my Windows PC with no problems. I tried on my wife's Mac with Safari 5.1.5 and I got the same error. So it is obviously an issue with the browser, not my machine.

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.

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 have my set Mac Pro to sleep after 1 hour of "inactivity" and not wake for ethernet administration access.My question is: What is "inactivity"? It seems that my computer never sleeps fully. I have iStat Menus and Dropbox installed. Will the computer sleep no matter what if I don't touch the keyboard or mouse or unplug/plug stuff in/out? Or will certain apps keep it from sleeping? I am worried that something is preventing it from sleeping.

My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV. So what I need to do is to have some way to tell it to treat the secondary display as the primary display.

San Francisco - It may be the quickest $10,000 Charlie Miller ever earned.He took the first of three laptop computers -- and a $10,000 cash prize -- Thursday after breaking into a MacBook Air at the CanSecWest security conference's PWN 2 OWN hacking contest.Show organizers offered a Sony Vaio, Fujitsu U810, and the MacBook as prizes, saying that they could be won by anybody at the show who could find a way to hack into each of them and read the contents of a file on the system using a previously undisclosed "0day" attack.
Nobody was able to hack into the systems on the first day of the contest when contestants were only allowed to attack the computers over the network, but on Thursday, the rules were relaxed so that attackers could direct contest organizers using the computers to do things like visit Web sites or open e-mail messages.Miller, best known as one of the researchers who first hacked Apple's iPhone last year, didn't take much time. Within 2 minutes, he directed the contest's organizers to visit a Web site that contained his exploit code, which then allowed him to seize control of the computer, as about 20 onlookers cheered him on.
He was the first contestant to attempt an attack on any of the systems.Miller was quickly given a nondisclosure agreement to sign, and he's not allowed to discuss particulars of his bug until the contest's sponsor, TippingPoint, can notify the vendor.Contest rules state that Miller could only take advantage of software that was preinstalled on the Mac, so the flaw he exploited must have been accessible by, or possibly inside, Apple's Safari browser.Last year's contest winner, Dino Dai Zovi, exploited a vulnerability in QuickTime to take home the prize.Dai Zovi, who congratulated Miller after his hack, didn't participate in this year's contest, saying it was time for someone else to win.
