Non-functioning sleep light

I'm trying out Leopard 10.5.2 on a G4 17" iMac, 1.25 GHz. When it goes to sleep, the sleep light doesn't come on. Thus there's no way to tell whether the computer is off or asleep. This was a problem starting with 10.5.0. The sleep light worked correctly in Tiger. Is there a fix for this?

I have found that the computer goes to sleep when it is logged into the admin account, but it won't when it is logged into a standard or managed account. It also goes to sleep when it is booted from an external HD that also runs Leopard 10.5.2. I just can't figure out why it won't go to sleep in the non-admin accounts. (iMac G4 1.25 GHz, OS X 10.5.2)
Any ideas out there?

Ultrabase Suddenly Non-Functioning; Strange Lighted Dock Indicators

X200 w/ Ultrabase on Win7. Worked fine this morning. Disconnected x200 from docking station properly this morning and hibernated, as usual. Returned, dropped x200 into docking station:
Not Working:
- external mouse
- external keyboard
- docking station speakers
AND - on the left side of the docking station, where the un-dock lever is, all three lights are lit: green arrow left of undock button, green arrow right of undock button and red stop indicator right of undock button.
I've performed a variety of reset functions: restarted, shutdown, unplugged keyboard/mouse [they work when plugged directly into x200] - all to no avail.
I've just seen that a BIOS upate came out in December 2010, so I'm off to upgrade that, but really can't see that it would cause this freakout. HELP!
UPDATE 1:
Updated BIOS [3.17] - no change.
Further details:
-apparently the docking station is simply not supplying power to the ports since
--no lights on keyboard
--cd drive not functioning
UPDATE 2:
Apparently it is a power issue. Passthrough ports [monitor] work fine, but those requiring power do not. I removed the battery from the X200 then docked to ultrabase - booted up and all peripherals work. What causes such a problem?
Solved!
Go to Solution.

After booting up w/o the battery in the X200, I shutdown. Then slipped the battery back into the X200, started up and all is golden. Crazy! Hopefully this does not become a regular occurence - my hair may go white even faster than it is already!

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.

Sleeping light & keyboad lights failure

Dear all,
I read the posts archived in these forums on the following issue but as there was no real guidance coming forward I thought to restate the issue I'm facing in case there is fresh knowledge on it.
A couple of weeks ago, the sleep light on my powerbook G4 started to come on all the time. I didn't noticed it until tonight, but it seems that when this occurs the backlit keyboard is also non-functional. This doesn't happen all the time, but now most of the time.
A friend told me that this was an indication of an issue with the USB ports, which would be grave because they are linked directly to the logic board.
I'm not sure if it is related or not, but I had some relatively serious problems with the directory of my hard drive (sibling link failures). I spent a couple of days cloning and then fixing the problems with Diskwarrior and Disk Utility. It appears the directory is fine now (though I did have to do an archive and install and could, if necessary, clone the good drive and wipe the original drive and start completely afresh). The problem, however, of the sleep light has not gone away. My friend had suggested that an erase and reinstall might cure the issue.
Can anyone give any practical advice on this issue? I cannot afford to lose my logic board, especially given that I live in Egypt where a new logic board would be hard to find and may not be able to be fitted.
Should I worry? Does this symptom mean that my logic board is on the edge of the abyss?
Thanks in advance for any guidance.

Hey All,
I finally decided to check here, as none of the fixes I attempted appeared to be working.
If it is an L-Board problem, them I'm in deep doo.
I'm currently in Panama, and thought that it might be a problem with some sort of variance in the power cycle here, as my first couple of days here, the PowerBook refused to charge fully.
It would keep at a constant level, and only draw power when it dropped below.
None of the various locations I tried provided relief, until recently, and now P]power's fine and at 100%.
Except I noticed the flashing 'sleep light' last night, tried checking around.
No fixes, and in the last several hours, I just noticed the 'no backlit-keyboard' issue (as it got darker, and it didn't come on).
There's a MacStore (authorized reseller type), I'll have to try them and see if they can do anything, as my AC contract is still valid.
Crikey, this *****.

K8N Neo4 (MS-7125) USB, Mic, S/P Out, and LAN ports all non-functional

I'm hoping someone can give me a hand with this. I'm not a novice when it comes to motherboards but this particular board is making me feel like it.
Ok, I've got a K8N-Neo4 MS-7125 model. Athlon64 3700. I have all the current drivers and ran the liveupdate to make sure.
The LAN port will light up, but the Device manager will not recognize it, nor will the LAN utility.
The board has 4 USB ports. The top two are non-functional, the bottom two work.
The S\P OUT port has never worked, nor do I know how to engage it or find it on the device manager
The microphone....this one is fun. Its like the microphone is stuck in a feedback loop. Whatever comes through my speakers, is heard on the other end by other users. I am not heard at all, although I can hear myself through my OWN speakers. Even with the mic unplugged, people still can hear my speakers. Imagine having your speakers plugged into the mic jack. The only way to kill the feedback is to actually go into the sound manager and mute the whole mic system.
I can live without the LAN and USB ports, but it would be a HUGE help if someone can help me with the mic and S\P ports!!
Thanks!!!

Ok, I'll do my best to remember everything

120GB Seagate 7200 RPM Harddrive (IDE) Partioned two drives
1x512DDR ram PC3200 400mhz
As for the flavor of the NEO4 the only other numbers I know of, is on the board it says N1996 right below the processor. Is that what you need? Its a PCB V.3 board nvidia Nforce4.
Speakers are standard cyber acoustic
Logitech Mic/Headset combo
This particular case allows for hookups for headphones and mic in the front. The case has jumpers in the back that allow you to gain access from the front (but you probably already know that). I've always used the front MIC/Headset jack, and I have a splitter in the back for the headphones and that jumper. In trying to resolve the issue, I tried every jack with the microphone (even the ones that I know are labeled as speakers). I do get my own voice through MY speakers on the front jack AND the mobo jack.
Hopefully I got you enough info!
Thanks in advance!!!

Non functioning system

Purchased a KT3 Ultra2 after reading good reviews. Replaced old Chaintech CT-7AJA motherboard. Fitted new 512MB DDR memory module (PC2100). Reconnected all devices etc. Switched on power. Front panel power LED came on. Hard drive LED came on for 20 seconds. Then nothing. No screen activity at all. No P.O.S.T. messages on screen. Put a floppy disk in the floppy drive. Floppy light did not come on after a reboot. Tried booting without memory module and beeping sounds heard. Replaced memory, still non functioning system. Put old mother board back. Every thing works fine. Took board back to PC World who replaced it. Tried again. Still non functioning. The problem is not my processor as it still works fine on old motherboard. (Removed sticky label from your socket A socket and used special cooling compound on heatsink).Problem is not my devices as they work fine on the old board.
Has anyone else ever had this problem?
It doesn't seem logical.
Any suggestions appreciated.

Why?? It is not even posting so it has nothing to do with OS problems. Yet. Even so I can't see any reason to format and reinstall an OS just because you have a new MB. Driver conflicts can be sorted out in safe mode.
To Geoffery, What are your PSU current ratings for 3.3V and 5V rails? Are you positive you have your heatsink around the right way? Machined slot must go over the raised portion of the CPU socket.

Tx2z - CPU non-functional?

Hi, my tx2z died on me this morning around 5 am when I tried to turn it on to finish up some engineering homework. The computer power on, fan on for a bit, but it got stuck on the black screen with blinking caplock and numlock light.
I don't know if this have anything to do with it, but now I think about it, it might be related. Last time I use it, it was the same day, or night, around midnight. I was working on some physics homework on the laptop with my friend. So I finished my part, and went over to help her. So when I tried to show her how to solve the equation on the calculator, we got a static electirc shock, and I didn't even touch her. Ok, so we laughed about it since we are doing stuffs dealing with electric fields. When we finally finished at 1, I went back to my dorm with the laptop, put it down to let it charge. Then when I try to do my engineering homework soon after with the computer, I was shocked again. This time by touching the comptuer.
So I believe my Tx2z died because of "CPU non-functional" according to the LED Blink Sequence table. The LED only blinked once in each cycle. Is that correct?
So if this is the case, what are my options? I doubt I am still under warrenty, since I just got the laptop before going to college 2 years ago. CPU non-funcational means that the CPU is dead and need replacement, right? And if I am correct, it is usually not possible to install new cpu in laptop. So I need to send it in and let them replace it? Will it be cheaper with I just go buy a new computer?
I am still hoping that it is not the CPU problem, since I really like this laptop, it is really not that old, and I have been taking care of it. It does overheat very easily though, sometime burn my hand when I am doing some 3D modeling / rendering. But even on power saving mode, when I am just checking email, it still overheated.
Any replies, helps, suggestions will be appreciated, thanks.

yup, I have pretty much given up by now. I started to make a list of hardwares that I want to buy to assemble a new computer. Tablet is good, but the fact that it can't last me through college, that's just sad. So $400 to repair, and the new computer that I am planning to put together cost around $500. I think I will go with the new one with way more processing power, way better cooling, and most important, the ability to upgrade / replace broken parts without having to pay a fortune.
LIST
Case, power supply, motherboard w/ ATI HD4250, AMD Phenom ii x4 3.4 Ghz, 4 GB DDR3, 1 TB HDD, DVD Burner, Card Reader...
So as for the tablet, I am starting to harvest parts from it. So far, ripped the hard drive out to recover some data and to use as an portable hard drive. Will probably take the RAM out in a day or two. The ony big disappoinment about not fixing the tablet is that the touchscreen is pretty much wasted, since I have no clue how to utilize that. Wish I have taken Computer or Electrical Engineering.

Helvetica regular font CS6 Yosemite non-functional

I have two Mac computers, both using Yosemite and CS6 suites and the Helvetica regular font on both of them is non-functional at this time. The font will work on other applications like Word, and even show up under the menus on CS6 programs, but when you select Helvetica regular you get an error. If an old file uses the Helvetica regular font, the file won't print or even save until the font is replaced with another font. The font checks out as ok in the font book program. The other Helvetica variations like Light, bold, etc. work fine. As far as i have been able to discover, all of the other fonts work as well. Both computers work identically, so I can't imagine the font file is corrupted...
Any suggestions?

kitcmac,
Is it a free Helvetica font or something, or is it the genuine one from Linotype?
In the former case, you may be out of luck: Illy is particularly particular about the quality of fonts, because she can work with them at a deeper/higher level than most, so you can easily have a font that works in all other applications, but Illy refuses to recognize it as a font.
Some failing fonts discussed in earlier threads have turned out to have rather basic flaws, such as redundant, superfluous, or (if I remember rightly) even stray points, or other clear errors in the paths that they consist of.
If it is a free one, you may need to get the real thing or look for similar fonts that Illy is willing to work with.

After Lion install, Mac won't sleep (no pulsing sleep light)? This worked for me!

I know there are a plethora of suggestions out there as to how to correct the no sleep light issue since installing Lion. I tried every single one of them-- PRAM and SMC resets, looking for "little snitch" and other apps, and even trashing a preferences folder. None of them worked for me.
This is what did work. APPLE! Listen up!
1. Unplug the magsafe power cord from the computer now or in step 3.
2. Close lid to laptop.
3. Unplug magsafe power cord.
4. Wait a few seconds.
5. Watch as the sleep light begins to pulsate.
6. You can now reattach the magsafe power cord, if you'd like. It doesn't affect sleep mode for me.
After doing this, I open the lid to my MacBook and it's like old times. It takes the display a second or two to come on as it wakes from sleep. It's exactly how it should be.
I hope this helps for most if not all of you, and I hope that Apple quickly determines how to fix this problem with Lion.

Yup, pmset -g assertions will let you know what's preventing your computer from sleeping.
As for AC vs battery, there are 3 profiles for sleep conditions - AC, battery, UPS. Use the "man pmset" command to see more details. Depending on which profile is active, different conditions may or may not prevent system sleep.
I also made a small app to help with diagnosing the problem, if anyone is interested. Source code is provided. If you don't trust it, just use "pmset -g assertions".
Hope Apple fixes it soon.

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem?

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

Is non-functioning key repair possible and practical?

I have a 2008 MacAir. The shift key on the right side and the return key either don't work or don't work reliably. Is it possible and practical to have them fixed?

The device does report a IP address, and the 'Internet' indicator lights solid, but it appears that it cannot communicate out. The Power LED blinks three times, repeated, indicating that it cannot connect to the Vonage server.
Linksys EasyLink Advisor does not detect it being on the network.
I also contacted Vonage Support, and they declared that my device is 'non-functional', so I am proceeding with a new device.
Thanks for your help!

Just bought an iPhone 5C.. Safari is non-functional! A blank frozen screen! Any one else experience this? Horrid design Apple! It's your freaking web browser! Google Chrome works but not Safari! I may simply return this "upgrade" unless someone can help

Just bought an iPhone 5C.. Safari is non-functional! A blank frozen screen... What gives? Safari is Apple's browser for gods sakes! Google Chrom works but not Safari? This is nuts. This is an "upgrade"?? Anyone else experiencing this? Or should I just give up and return this

Are you always like this?
First try a Reset: Hold down the home and sleep buttons, wait for the Apple logo, let go of the buttons.

Sleep light off

I have a MacBook Pro 13in (purchased Jan 11) running the latest Mountain Lion OS - recently, putting it into sleep mode causes (not necessarily immediately) the sleep light that normally waxes and wanes to go off and that is an indication that when you try to wake up the machine nothing will happen. Depressing the "on" button for 10 seconds will allow the next depression of the "on" button either to restart the machine or to wake up the machine through a process whereby the screen as it was before the machine was put to sleep is revived through a grey miasma which, after a couple of minutes, becomes full brightness and the frozen cursor is unfrozen.
In all, this is a depressing intrusion on the usefulness of the sleep mode: it means recovering from sleep either entails a full restart or approximately 3 to 4 minutes getting function back.
Disk Utility reports no problem. My software is up to date and I have even re-installed Mountain Lion to attempt to avoid the problem with no success.
The thought it might be a Hard Disk problem causes me to keep my external hard drive regularly attached with Time Machine on but it feels like some software glitch.
Anyone any thoughts? Assistance most gratefully accepted!

Power Button only works at startup, but non-functional afterwards.

For a Macbook Pro 15
A1226 / OS 10.6.8 / 2.2GHz Intel Core 2 Duo
(1) When the computer is on, and i press the power button , the shutdown menu used to come on, but does not now.
(2) When i press & hold the power button, the computer does not force shutdown, even when i hold it down for 30 seconds.
(3) When I shutdown the computer via the apple menu, i cannot start the computer up using the power button
(4) However, disconnecting the trackpad ribbon cable from the logic board, then reconnecting, the power button is operational allowing the computer to start back up
(5)When I put the computer to sleep via the apple menu, it goes to sleep, and i can wake it up
(6) When I restart via the apple menu, it powers down then restarts without any problems
(7)The force quit keyboard short cut will not work most likely in that it uses the power button as a shortcut.
So pursuant, to (4) above, it seems that the power button is non-functional after starting it up, and will only work after connecting/reconnecting the ribbon cable
Bracing myself for no replies or "take it to the genius bar"

Try resetting the SMC http://support.apple.com/kb/ht3964

Sleep light firmware update did not work altogether

Original 1.6GHz iMac G5
10.4.3
The intention was simple. I wanted to run the sleep light firmware to dim the sleep light pulses during the early morning hours. So I installed the firmware package and then went to run the firmware update. At the end of the update, I get an error that goes something like this: "An unexpected error occured. The software was not updated." I was then told to shut down my computer to try again. But I can't try again, because when I go to run the firmware package again, I am told that my firmware is up to date. Yet the sleep light is the same intensity as before, no matter what hour of the day (whether it is 23:53 or 1:53, as examples) I set the time for. I gave the sleep function some time (between two pulses and 5 minutes for some tests) for the dimming effect to occur potentially, but it never did.
Now what do I do?
Specifically:
[1] How do I get to rerun the firmware so that I can get the light dimmer?
[2] Why did the error even occur and prevent the firmware from being updated?

Reinstallation of the package led me back to the ~"Firmware is up to date" message, so now I'll try the chat agent. (In the future, link me to where the chat agent is, because I did not find it until I did a general search from the main website, and searching is a huge pet peeve of mine.)
