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.

PowerPC :: G5 - What Does The Ambient Light Sensor Do

Dec 6, 2008

[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.

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 :: 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.

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 :: Display Brightness Ambient Light Sensor?

Aug 31, 2009

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?

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 :: ISight Light Won't Turn Off And IMac Freezes At Shut Down?

Jan 7, 2011

tonight I started having trouble with my intel iMac (running OSX 10.4.11). I'm having issues with two things (bolded for those skimming):

Out of seemingly nowhere, my iSight light turned on and now wont turn off. The only program I had open at the time was Firefox. When I try to open up PhotoBooth it says this:

There's nothing listed under USB High-Speed Bus in the system profiler either.

I've tried logging out of my user account, restarting, shutting down, unplugging and holding the back button for 5 seconds ...none of that worked. I tried resetting my Mac's PRAM and NVRAM. That didn't work either, and that's where a second problem appeared: when I try to shut my computer off, it freezes. I have to shut it off by holding the back button.

Is repairing the permissions and/or disk worth a shot? Or should I just take it straight into the Apple store? I hope it's not a hardware issue because I just recently had a new hard-drive installed after it broke down on December 15.

PowerPC :: IMac G5 Intermittent Shut Down?

Nov 13, 2006

I have one of the 20" iMac G5's covered by the warranty extension for the intermittent shutdown problem. The problem is that I am out of the country, and where I am has very unreliable Apple service. It would be gone for weeks and weeks. I am considering flying back home to get my computer repaired. The computer shuts down multiple times a day without warning.

What are the chances I can find an AASP in the DC area who can do the repair in a day or two. I have read that the repair is only a power supply swap and can be done in 15 minutes. What do y'all think?

My other option is to just buy a new computer and worry about repairing this one in a year or two, which is a $2,000 hassle.

IMac :: Using Ambient Lighting?

Nov 21, 2009

When trawling through the ridiculously long thread showing pictures of peoples Mac setups, I noticed an awful lot of ambient lighting and want to try a little myself. It's a painfully wanky thing to do, but with the iMac in the living room there just isn't any room for an ordinary lamp so a blue LED could look stunning.

What do people use for ambient lighting? It seems to be that, with USB ports being in fairly good supply behind the iMac it would be criminal not to go with something USB powered.

I found this: [URL]

Looks like it might do the trick, and even comes with a suction cup which *might* attach to the back of the iMac or the stand. The same light is also available in white, red, green or a colour changing version, but I'm convinced blue is best.

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.

Info:
iMac, Mac OS X (10.6.8)

PowerPC :: IMac G3 Monitor - Slight Red Color On Right Side And Light Colored Box On Screen

Sep 24, 2006

I just got an IMac G3 running OS X and OS 9.2.2. I am having monitor problems with it, the monitor has a slight red color on the right side and if there is a light colored box on the screen I get almost a run effect going to the right. This happens in OS X Tiger with all the updates, OS 9.2.2. I also have all the firmware updates, an external monitor looks great.

Windows On Mac :: Boot Camp 3.1 Allows The Keyboard Light To Completely Shut Off In Windows 7?

Jan 20, 2010

Would have checked this myself but I haven't gotten around to installing Boot Camp 3.1 yet.

Anyone with a uMBP try to see if Boot Camp 3.1 allows the keyboard light to completely shut off in Windows 7?

I described it more here.

PowerPC :: Mac G5 Won't Shut Down

Apr 2, 2007

My friend is using a Power Mac G5 and it will not shut down. When shut down is selected, it gets to a blue screen with the rotating progress wheel, or whatever, that is seen on start up. It will stick to this screen until the computer is forced off by holding down the power button. Also, occasionally, when the computer is powered on, the fan runs at full speed and nothing happens until it is forced off and turned on again. I'm guessing these two issues might be related. Any suggestions on what to do? We have tried unplugging all USB devices.

PowerPC :: Unable To Shut It Down

Jun 2, 2007

I have a PowerMac G4 that isn't saving the settings when I shut the computer down. I think it might be the battery on the mobo, but I'm not totally sure. does anyone know of any other reason why it would do that or confirm my suspicions?

PowerPC :: Shut Down It - Reset Everything?

Jan 24, 2008

everytime i shut down the computer it resets everything. takes off all the music i added in itunes ( still has firefox that i added in the finder though but i had to re-install it). i'm thinking the person who sold it to me did something to clean the machine when it was sold.

this is probably something easy but i'm not too computer savvy.

PowerPC :: G4 Wants To Shut Down After Sleeping?

Mar 25, 2008

My aging G4 Quicksilver is still very operable yet have had mysterious problems with mouse tracking, USB ports not being recognized and now the machine wants to shut off after being asleep for some time. Someone suggested that it could be a voltage regulation problem, but service personnel have not been able to duplicate the problem with a bench test. In short, when I have a startup problem (the startup button will start to glow, at startup and then the light goes out and the machine fails to boot) or if I find the machine turned off after I left it to sleep at night or a few hours during the day, I will open the case and shut it. This little nudge seems to be a temperary fix. Nervous it does make me that my time is short with this trusty box.

PowerPC :: G4 Locked Up - Cannot Restart After Shut Down

Jan 26, 2009

My PowerBook G4 15" alu 1.25 ghz locked up out of nowhere the other night (while only running firefox). Couldn't even force quit, so after a long wait I manually shut it down. Then I couldn't get it going again. I pulled the battery, let it sit overnight, and then it started up, only to freeze up again in 30 minutes. Same routine yesterday (though it lasted an hour or so).

I live in Germany and the only Apple store is hours away. And of course my Apple Care is expired. I've zapped the PRAM, reset the PMU, ran first aid on disk utilities (everything came back OK), but I'm freaking out. This thing is seriously important to me, and I can't afford to replace it. I've read plenty of speculation that it could be the logic board, or that it's locking up from overheating, or maybe the hard drive is going bad (though the tests come back OK).

PowerPC :: Not Starting Up - Automatically Shut Off?

Sep 14, 2009

My powerbook will not start up all the way. It suddenly went off yesterday and did not give any noticeable warning. I left it alone after trying to start it up several times. I tried again today and had the same problem. I will here the motor for a few seconds and then nothing. Also, it did come on twice, went off both times when titled the entire laptop up. So, if I tilt it at anytime it automatically shut off.

PowerPC :: G5 Not Turning On Only Red Light Shown?

Nov 30, 2010

Up until recently my PowerMac G5 has performed as it should for a computer its age. About two nights ago it shut itself down and I haven't been able to turn it on since. Power does cycle through the unit because all the fans will either cycle once or twice, or at the very least they will twitch. And now there's a tiny red LED on the motherboard and behind the power button that lights up whenever I try to power on the computer. I'm at a loss for where I need to go from here, though I feel rather certain that my computer has simply passed on. It's an original 2004 1.6 ghz single processor PowerMac G5, serial number unknown, since I can't turn it on.
