Sleep Light Application

I just came across the iMac G5 Sleep Light Application in my Utility folder. I thought the update took care of everything. Do I still need this? Why?

Hello Donald:
Here is the only knowledge base article I have found on the issue:
http://docs.info.apple.com/article.html?artnum=302039
I have one G5 (a very early one). When I ran the software update (I run it manually and then decide when and if I should install updates), the "sleep light" updater was in the list. Since my G5 is not in a sleeping area, I decided to ignore this particular update and did not download it. I set the updater to ignore this update. This is a windy way of saying I did not apply the update and it is not in my G5 anywhere.
At least some firmware updaters require you to install it and then restart your computer. When I installed a Bluetooth firmware update, I had to click on the updater icon and then restart afterward.
I hope this windy post helps. I am always cautious when I install firmware updates as they update more than software:

MacBook pro screen wont turn on mechine turns on but front sleep light is dim

So I was just browsing on chrome on my MacBook pro and suddenly the screen froze and from the top of the screen it started to get dim and came down right to the center of the screen and then another black shade ontop of that came down and stopped in the middle it did this until the top half was completely dark but the bottom half is ok and nothing happend oh by the way I was just on Facebook I wasn't on a website that was harmful to the Mac so any ways I then I held the power button until it turns off thinking it would work normaly but it didnt, when I turned it on I heard the fan turn really fast and then it slowed down and the front sleep light came on and it stayed like that, i could also hear the hard drive spinning inside I closed it and the sleep light is on it but now it brighter and it's not even going dark and bright like its supposed to do when it's sleeping. Can someone please help?

Try a SMC reset:
http://support.apple.com/kb/HT3964
If no joy try a pramreset: power off the MBP, power back up, before the start chime press and hold optio, command, P, R, and continue tohold them until your the chime 2 times then release. Reboot.
If still not happy try a safe boot, power up holding the shift key, continue to hold the key until you the progress bar and gear then release. This will show if it could be a third party software problem, this will boot the MBP with only essential applications running. Be patient as this takes longer than normal. Try things out, if normal, shut down and restart and see if things are still messed up.

Sleep light not "pulsing" when in sleep mode

Hey guys, i have a little problem with the sleep light... i don't know when this started, but i notice today, that when i put my macbook pro to sleep, the light just stays on and not "pulsing" like it used to do... is that normal?
How can i fix this?

This usually happens when you might have an application which is still running and is failing to quit. Check Activity Monitor for a list of all your processes.

Change display close actions, and turn off sleep light

I know apple doesn't like to make these things easy to change but here goes... my powerbook is in my bedroom. when I close the lid, I must put something in front of the glowing sleep light or it keeps ME awake. is there a way to disable it? or does this fall into the same category as moving the song name column out of the first position in itunes? apple has made a decision (based on who knows what input) and the end user is stuck with it...?
while we're at it: can I change the action performed when I close the lid? lock my user account but don't put the computer to sleep, for example? leave everything as it is but just turn off the display? mute the volume? show that I'm still online but attach an away message in adium? these are all things I could do with windows (tho I would never switch back) and I'm not sure why it seems so hard to do things like this with a mac.

Description and modification of the different hibernate modes
When the computer goes into sleeping mode, its behavior depends on a power management variable called hibernate mode. The hibernate mode can be set to different values:
* 0 : Default sleep behavior on most Apple computers. RAM is still powered on while sleeping. Wake up is fast. Safe sleep is disabled.
* 1 : Hibernation behavior. System is totally shut down while sleeping. RAM contents are dumped to disk. Wake up is slow.
* 3 : Default behavior on Powerbook HD computers. RAM is still powered on while sleeping. Wake up is fast. Safe sleep is enabled, so RAM contents are also dumped to disk before going to sleep.
Only a single mode can be activated at a time. In order to check what hibernate mode is currently active, the following command can be used in the Terminal application:
pmset -g | grep hibernatemode
In addition, users with administrator privileges can choose the hibernate mode. In order to do so, the following command can be used:
sudo pmset -a hibernatemode X
with X replaced by the value of the hibernate mode to set. You will be asked to enter your admin password. It will not be echoed.

Sleep light-12 inch powerbook

a few months back my sleep light became intermittant and often just stopped working--the folks at apple cust care walked me through some power tests etc, but it turns out that the latch release affects performance as does pressing the lid over the sleep light location. the sleep light just stops working at various times and jiggling the pushbutton release seem to get it going most of the time
do i have to have the sleep light replaced?
Powerbook G4 Mac OS X (10.3.9)

"null"?? (As in "null chance in getting it to run"?)
Anyway, thanks for your reply Sam. As I already hinted "I know it's not in the requirements". The tool (ran it when it came out) only confirms this.
Let me be clear (again): The issue is that a "Pro" notebook from Apple does not run this "between iPhoto and Photoshop" application. Though small it is nevertheless part of that lineup. In my case it's a few months old - sold as modern/latest/leading - but it's the current one as well. This is the official version. Quote: "packs a tremendous punch for doing everything" (http://www.apple.com/powerbook).
Don't get me wrong, for the most part I think it's a fine machine. But does it run with Aperture? Anyhow? If not, that's simply misleading PR on Apple's side.

MBP Won't Sleep automatically. Sleep light on. Not pulsing. Drive spinning.

I can get my new MBP SR to sleep when I tell it to but it won't sleep when it's supposed to according to my Energy Saver preferences.
Instead of sleeping, the screen goes dark and the sleep light stays on at medium - no pulsing. I can hear the hard drive still spinning. I tried changing my screen saver to one of the original Apple settings (Computer Name) but that didn't help. I'm going to try throwing away my Energy Saver prefs.
Any suggestions?
BTW - I took a closer look and I was a bit surprised at how many posts there are for the MacBook Pro on the Apple.com discussions. The most posts per day of any model by far. I know its a very popular Mac but this model seems to have more problems than we are able to solve. That worries me. Anybody else noticing this?

I had exactly the same issue and needed three hours to find out the reason. It was the Bluetooth Mighty Mouse. I had to disselect the *third option* in the *bluetooth preferences*. I have a German-language OS X so I don't know the exactly expression but it affects the ability for bluetooth devices to weak up the system.
If you have EyeTV 2: This application must not be running. If you have scheduled recordings that doesn't matter it will record anyway: It will wake up the Mac - record the thing - go to sleep again.
I have several devices connected to the MBP: Three external enclosures with harddisk drives (2xFW800, 1xUSB without sleep function), EyeTV 610, speakers - all those things did not prevent the system for going to sleep. All those devices can be left attached - up and running. The FW harddisks will go to sleep the USB not.

New Hardrive and now blank screen with sleep light on

My warranty ran out on one of my mbp's, so I decided to install a new hardrive in one. I went through all the steps, and was very cautious. Now when I turn on the laptop the screen is blank and the sleep light stays on the entire time. I hear the cd-rom do some stuff but that's it. If anyone can help me figure out what happened it would be greatly appreciated.

Well problem solved, had to apply some pressure on top of the case by the left i/o and next thing you know I hear the beautiful chime

Mac OS 10.4.3 and Sleep Light Update

So, after installing Mac OS 10.4.3 update through Software Update on my Rev. A iMac G5 I have experienced the same "fans at full blast" issue that others have reported on reboot. However, the fans went back to normal speed after the system loaded the Finder.
I now just noticed that the sleep light is very bright during the night time hours so I am guessing that this update removes the infamous and troublesome (for many) sleep light firmware update. Can anyone else confirm this?

Finally I find how to reset CORRECTLY the SMU and resolve the problem about the sleep light!
Pay attention, because to reset the SMU in iMac rev A - the first generation - like mine (dec. 2004) must open the backside of Mac and following the instruction like here: http://docs.info.apple.com/article.html?artnum=301283
at the point 11.
In a few words, disconnect all the plugs, open the back, reconnect the power cord, (in the center a little green led is on) ....
Press the SMU reset button (the small, metal button next to the internal power button, shown below) to reset system and power management.
Its work. wow
take care ;))

My Macbook Pro 17" 2.44ghz all of a sudden one day decided to not boot up. When the power button is pressed the sleep light in the front on the latch release turns on and there is a small running sound but it never boots up and the screen never lights up. Anyone else have this problem? Any ideas?
I'd love to repair it but not if it'll cost 500 bucks or more to replace the logicboard.
I appreciate any help

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

Sleep light flashes 5 times - no beeps. What does it mean?

I have a white 2008 Macbook 2.4 Ghz. I recently installed 10.6 from scratch via Retail DVD and the Macbook worked fine. I updated via Software Update and installed all the updates that appeared. There was also a Firmware update to install, which I did after the update to 10.6.8.
But since then, the Macbook has serious video problems.
It boots okay, but the sequence is now:
- front sleep light flashes 5 times; there are no error beeps
- I hear the startup chime
- the Apple logo and spinning wheel appear, and bootup continues
- at the point where the screen goes blue, and would normally boot to the desktop, the screen now goes black and the Macbook appears to go to sleep
If I wait for a couple of minutes, when I press a key to wake the Macbook from sleep: the DVD spins up, the sleep light flashes 5 times, and I now see the desktop. But then the screen goes black after about 10 seconds.
Before the screen goes black, I can see that the boot seems to have completed okay. I have a Wifi connection and the date and time are correct.
If I go really fast, I can move the arrow to the Apple icon in the top bar and choose Shut down or Restart.
I can boot from the internal HD, an external FW HD and an Install DVD.
I can hold down the Option key and I get all the bootable volumes to boot from. I can choose any of them, then start the boot process, but at the same point - the blue screen - the screen goes black and the Macbook goes to sleep.
The Macbook works perfectly fine when connected to an external monitor. In the Display preferences, only the external monitor is available. The Macbook monitor is not listed. As well, iSight and Photo Booth report that no camera is connected.
I've found some info on the Apple site re. the 5 sleep light flashes, but it only refers to the Macbook Air, and indicates a problem with the battery.
Has anyone seen this problem with the Macbook?

From EZ Jim's link, there was another link to this info at the Apple site, re. Power on Self-Tests:
The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
As I wrote, I don't get the Error Beeps. I've had these on other Macs, so I know what they are. Here, I only get the LED flashes.
What is interesting above is that they say that the Power LED will flash a corresponding number of times (as the beeps) PLUS ONE. In my case, then, if I got 5 flashes, then might it mean NO GOOD BOOT IMAGES IN THE BOOT ROM?
Anyway, it doesn't seem to have the flashing LED problem any more. No idea where to go from here.

My macbook isn't powering up and makes a beeping noise in time with the sleep light

Hi There I hope someone can help!!!
I had disconnected the power cable and left the MacBook in sleep mode with the lid shut. When I now go to open my MacBook up, and wait for my system to resume from where I left off the screen doesn't on and the sleep light goes off. when I close the lid the sleep light goes back on as if it is in sleep mode but the same happens when I open it again, no power to the screen.
I order to try get my MacBook working again I tried holding down the power button and switching it back on again but the MacBook now looks as if it is going to power up but the sleep light comes on for about 3 secs and then beeps, then every 4-5 secs constantly the MacBook beeps once in time with the sleep light (to note the sleep light is not following its usual fade on fade off rhythm).
I have tried resetting the SMC using the shift command control option and power button (also this is the only way to stop the beeping and flashing) and when you try and switch on the MacBook if you just press the power button it just follows the same beep with sleep light routine, but if you hold the power button in then the sleep light then flashes quickly about 4-6 times and then starts to beep in time with the flash again.
I will also add I have not reconfigured anything or added any RAM to my MacBook it is still on the standard (manufacturing) configuration as I have been looking about for anyone with similar issues and the main question back seems to be have you changed the RAM, I have also tried resetting teh RAM and the proble still persists.
If someone can help it would be awesome!

Here's the Apple support article on beeps https://support.apple.com/kb/HT1547

Is this sleep light behavior normal w/ a MacBook Pro?

This is the deal. I just purchased a new MacBook Pro 2.4GHz Intel core 2 Duo and I've noticed that the 'sleep light' comes on and stays on when I have my Cinema Display plugged in with the laptop cover closed down (so, therefore, I'm using just the external monitor, not the MBP's screen). It isn't 'sleeping' (it's not pulsing in and out as it does when it goes to sleep), but the light comes on steady whenever I close the lid regardless that the MBP is completely awake and being used with an external monitor.
I also noticed that while I was in the process of migrating data from my powerbook to the MBP, when the screen went dark (non-activity) over time, though the computer was transferring data via firewire, that when the MBP screen did go dark the sleep light immediately turned on. When I moved the mouse or touched a key of course the screen came back and then the sleep light went out. I was very surprised with this. IS THIS NORMAL FOR A [brand new] MACBOOK PRO? Did apple change things from how the PowerBooks were set up?
With my powerbook, the sleep light only comes on when it's ACTUALLY SLEEPING and then it pulses. It doesn't come on steady when the lid is closed. So this is quite different from what I'm used to and want to know what is supposed to be happening with the MBP.
The MBP goes to sleep properly in the various situations I've put it in. So far it functions properly. Except for this sleep light issue. And after doing some reading here I found there to be a number of issues with the MBP's 'sleep' and/or power management systems. And I'd like to know from other MBP users - Is this steady sleep light normal when the laptop screen is 'not in use' tho the computer is still ON and working?
Anyone notice any of these things as well? Your timely responses are much appreciated. I decided to ask here first, as I often find other users as knowledgeable and helpful as any resource out there. Thanks in advance.
BTW, and this is a side note: But I didn't install the battery update (I think it's 1.3?) for my MBP because of the scores of issues I've read about it thus far. Your thoughts on installing the update are also appreciated, if you have any.
Regards, Elizabeth

You have a macbook pro too (as noted), does this happen with yours? If apple changed things and it's normal, like as you stated that it was lite so you'd know you're computer is 'on' but I'd like to know for sure if that's what it's supposed to be doing. (nip it in the bud if there's a problem)
I know it isn't sleeping (not pulsing) but since the light is on (steady), it is something I noticed right away. For example, right now as I type this, with the MBP on my desk w/ the cinema display plugged in (w/ a keyboard) and the lid is closed on the MBP, the light is ON right now. Not pulsing, but a steady light. Doesn't seem like it should be, to me. (at least in my view)
Thanks for your reply Josh.
