IMac Power Issues -Won't Turn on Most of the Time, Sometimes it Does

I'm having an issue that as far as I can tell doesn't really fit into any of the usual categories of problems.
Starting immediately after I installed Snow Leopard, when I turn my computer on (after having been shut down and left for a while), it makes some sounds as though the hard-drive is starting, and if a disk is in the disk-drive revs, but there is no chime and the screen doesn't turn on and nothing happens. I've since discovered that if I unplug everything from the computer including the power cord and remove the power cord from the wall as well (dunno if that part is essential), wait a long time, and then only attach the power cord, it boots up fine. Then I can use the computer as normal with no issues whatsoever. I can restart it as much as I want and it'll boot up every time until I shut it down (then the problem starts again.)
I called Apple Support and they had no idea what was up, so they sent me to a store to speak to a genius. He wasn't sure but he figured it was either the logic board or the internal power unit (or something like that). They wanted $800 to fix it, so I said I'd think about it and decided to work on it more myself.
Once I got the computer on I ran Onyx, Disk Utility (both off the Snow Leopard disk and off my computer without it), the hardware diagnostic test extended test, and I reset the PRAM and Power Manager. Onyx and Disk Utility found issues but fixed them, and I ran them again after I fixed those and they didn't find anything.
I'm pretty sure I've covered every test I can do. The only possible conclusion I can think of is that the power supply is slowly failing when it comes to booting up, but it seems strange and way to coincidental that it happened the same time I installed Snow Leopard. It also doesn't seem to make sense that the computer is fine once I do get it on and that I can somewhat reliably get it to boot by leaving it unplugged long enough.
Any ideas would be greatly appreciated.

Hello BB:
Your personal troubleshooting has been comprehensive. One question:
I reset the PRAM and Power Manager
Is this the SMC/PMU?
If that is the case, I think I would assume a hardware problem.

My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2 seconds and it won't turn back on. Should I replace the battery?

My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2+ seconds and it won't turn back on. Should I replace the battery? It doesn't hold a charge either...

EmadJamal,
the battery won’t melt because of long connection to the AC charger, although that has the potential of reducing the battery’s life.
Do you have access to a second 60 W AC charger to test with your MacBook Pro, or access to a second 13-inch MacBook Pro against which your AC charger could be tested?

I added exceptions for the pop up blocker but most of the time it still does not allow the pop ups for the sites I listed as exceptions

the pop up blocker is inconsistent. i added websites to the exceptions list but most of the times when i load firefox it does not allow the exceptions...sometimes it does but i can't find any reason or consistency as to why it sometimes allows them and sometimes doesn't. They are clearly listed on the exceptions option.
What is wrong?

Brand new iMac 21.5" won't turn on - straight out the box

I just picked up my new iMac today and unpacked it etc, but it won't turn on. The wireless keyboard and mouse are supposed to be paired with it and ready to go, but the on switch on the keyboard won't turn the screen on (as far as I can tell there is no on switch on the iMac itself). The green light on the keyboard keeps blinking but doesn't connect to the iMac to turn it on. I've tried a different power cable in the iMac but that makes no difference. Does anyone know of a solution, or will it have to go back to the shop ( ) ?

The power switch is locate in the back on the lower left side as you look from the front. Did you connect the power cord and plug in the computer? There is no power button on the keyboard.

MacBook won't turn on 98% of the time, help! Very weird things happening!

Hi there, any advice you have for me would me much appreciated. What happened with my Macbook is all very strange.
So, the morning before last, I was on my Macbook (which I bought in 2006 so it's on the older side, but otherwise worked great) and it was running low on battery. I was late for work so didn't plug it in before leaving. I left it open. However I have no roomates, pets, etc.
When I get home that evening, I plugged in the powercord and it wouldn't turn on. After trying a million different things, like taking the battery out, reseting the PRAM, etc, there were a few times where I got it to turn on, went through the log on screen, and was able to use my computer like normal for about 5 minutes or so, and then it would just shut off.
There were also many times when I would pres the power button and the screen would flash like it was about to turn on, and then it would make the noise that the computer makes when you're typically on 0% battery and it shuts down. Later in the night, when the computer was closed but plugged into the power outlet, it was by itself (meaning I wasn't pressing anything) making the noise that it was restarting. It made that noise about every 30 seconds for a few minutes. Weird.
It was also doing inconsistent things re: the sleep light. At times it was on, including when the computer was closed, and sometimes it would go from on to off. Also, the battery/charing was doing weird things. The few times I was able to get past the log in screen it showed that it was at 0%, even though the light on the adapter was green and it had been plugged in for a long time. Another time the battery icon had an X through it. I have 2 different batteries and neither one of them seemed to make a difference.
Also, yesterday I brought my computer into the Apple store and they put in a battery that was charged and it didn't seem to make a difference either. One more weird thing: when I did get the computer on in the spotlight bar it said it was indexing??
Anyways, I'm just confused/upset, etc. because I literally did nothing to the computer. I didn't drop it/spill on it, etc. I'm also frustrated because the guy at the genius bar litteraly only spent like 5 minutes looking at before he said i was SOL. He said it was the "main board" that was the problem. One of the things like I'm just confused by is if the main board really does need to be replaced, then how was I able to get the computer on and working those few times???
Sorrry this is so long, any help would be awesome!! I just don't have the money to buy a new computer, and I'm not sure it will be worth it for me to pay $300 to have it fixed when my computer's already pretty old and other things haven't been working for awhile (like my disc drive, camera). THANK YOU!!!

BCS: Performance Issue - Most of the time is spent doing commit work.

Hello,
We are experiencing performance issues with our BI server. This performance issue can been seen during our BCS runs. Our DBA has indicated that he sees a very high percentage of time time is spent doing "commit work".
Curretly, we are running BI7 nw2004s, Basis 700, support pack 14.
Anyone else experience this? As the BCS run is mainly stanard SAP code, I was wondering if there may be some snotes that correct this?
Thank you for any help you could provide us.

If it is related to SEM-BCS and new EHP releases, then there are still big problems with the monitor and tasks status management (meaning problems with performance). Is it the case? If yes, then you'd better look for already released notes reg this and formulate your own OSSs if you don't find anything relevant.

[solved]WoL fails 'most of the time', sometimes

Sorry for the cryptic topic name, but I didn't want to make it too long
I've been setting up wake-on-lan on my desktop computer, with my server waking it up. I followed the wiki entry and everything worked. I didn't even need ethtool. When I SSH into my server and run
sleep 1s ; wol -v -p 97 -i 192.168.1.3 00:07:E9:73:09:44
and then suspend my computer (s3) it wakes up a minute later. I've also tried adding it to the crontab of the server and it works. But when there is a big gap between the suspending and the wake-up it fails. The gap seems to be roughly an hour or so. Yesterday evening I changed the crontab on the server to this, and shut off my computer.
* 6,7 * * * wol -v -p 97 -i 192.168.1.3 00:07:E9:73:09:44 -w 10
The computer woke up about 6:45.
Google turned up a hit about a fedora user where it failed after an hour, but that was because the router went into sleep mode, but my server torrents all night.
I tried with S1 suspend, but my comp didn't want to suspend with that.
One evening when it didn't woke up I went to my server and started issuing manual wol's, at roughly the 10th try I succeeded, no clue why.
I haven't really figured out if the -w switch makes any difference, I didn't really understand the man page's description of it.
EDIT: yay 400th post!

It worked this evening after a 4h sleep with
* 20 * * * wol -p 97 00:07:E9:73:09:44
in my crontab. No idea what caused the problem, but it'll hopefully work now. I'll see if it works tomorrow.
Nobody answered to my thread :'(

My MacBook Pro shut itself down and now it won't turn back on and the power light keeps flashing a green and amber but very dull. Help please!

My MacBook Pro shut itself down and now it won't turn back on and the power light keeps flashing the amber light. I don't know what to do, and this has never happened before.

IMac G5 (PowerPC) won't turn on

Hi there,
My old iMac G5 (PowerPC) won't turn on. Its been having problems for about a month where it would randomly turn off (not shut down, but completely turn off). It would also take about 3 or 4 tries before it would start up. Now I can't even get the computer to turn on at all.
I've created a bootable start up disk, but that's essentially useless until I can get the computer to power up.
I've tried unplugging all peripherals and unplugging the power cord for 10 secs then starting up while holding the ON button on the back. It starts up for 1 sec, then cuts out again.
I've taken a look at the logic board. There are no bad caps.
Could it be some bad RAM? Could that prevent my computer starting up?
Does anyone have any advice?
Thanks!!

Add another IMac G5 to the dead. The only thing that happens with this system is LED 1 is green but LEDs 2,3,4 are all dark. There is no fan, no hard drive noise, no flash of light. Caps physically appear intact in both PS and Logic board. Hard drive removed, DVD drive removed, RAM reseated, switch checks out ok on an ohmmeter check. There is voltage across the power switch contacts but no reaction at all from the computer when the switch is closed. CMOS battery checks good with proper voltage.
I had two other systems that have bad caps, one in the PS and the other in the logic board. These were mixed to give me one good system and the other with both bad PS and LB. I have replacement caps to try to bring the salvaged system back to life but this third, totally dead system has no indications of what might be happening. Pushing both internal switches on the logic board, with AC attached and not attached, has no effect. All the standard key combos (Terminal, Single User, Safe Boot, Command X etc.) has no effect.
Anyone have a guess or suggestion?

Kernel Panic: You need to restart you computer. Hold down the Power button until it turns off, then press the Power button again.

I apologize for writing a book, but I think explaining the full story may possibly get me a correct answer. I hope that someone can give me some insight as to what is the problem with my MacBook Pro. I have a MacBook Pro (15-inch Early 2008), model identifier: MacBookPro4,1 running OSX Lion 10.7.5 with 6 GB memory. My wife first noticed a problem with the display. Every so often it would get fuzzy with jumping lines going across the screen making it vitually unviewable. The final time that incident took place the computer froze which required holding down the power button to restart the computer. The computer started up to the point of the Apple logo and the spinning gear for quite some time until the screen darkened from top to bottom displaying the following message in five different languages: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." I have read other blogs and support communities where people get the message intermittently, but my computer would not go past that point no matter what. Through research and the Apple Store I was told that this is a Kernel Panic. The so called "Apple Genius" at the local Apple Store was unable to get the computer to boot past that point even with his gadget. It would not startup in recovery mode, safe mode or off of a disc. I forget exacty what he told me, but he said it was getting past the first two startup steps, but it would not get past the third step which is to mount the desktop. He guessed that it may be a problem with the hard drive; a loose wire or something or other. I disconnected the hard drive completely and took it out. Everything appered to be connected properly. Then I installed it back correctly, but it did not solve the issue. So I guess I disproved his theory of a loose wire... I purchased ProSoft Data Rescue 3 and connected my MacBook Pro to another Apple computer using a firewire 400 cable. I was able to get everything I needed off of the hard drive. I did some more research and I decided to restart the MacBook Pro in verbose mode (holding down the command button and V button). The computer magically started up!!! I was upset that I wasted my money on the ProSoft Data Rescue 3. I managed to take additional items off of the computer and back it up on to an external hard drive. After some time the computer froze. I repeated the power button process to restart and received the same kernel panic. I managed to get the computer to startup approximately six or seven more times via verbose mode; each time the computer staying on for a shorter amount of time before it would freeze. I managed to run Disk Utitlity. I performed first aid to fix the hard drive and it said that the hard drive appeared to be fine. After first aid I erased the hard drive and booted off of a Lion disc to perform a clean install or an erase and install. Lion installed until the progress bar got the the end where I received a message that there was an error installing Lion, please try again. Each time I attempted to install the software I would receive the same message. Eventually the computer would not boot from the Lion disc. I went back to the Apple Store and the Apple Genius was able to get the computer to boot off of his gadget where Lion istalled completely. I set up the computer as a new computer. He said that he partitioned the hard drive as DOS and then back to Mac OS Extended (Journaled) which would get rid of any errors the drive may have had. He guessed that the problem was the hard drive, but was not exactly sure. When I brought it home I installed all of the software applications I had on it previously. Approximately three days later, which may have been the fifth of sixth time starting up the computer, the display became fuzzy again and the computer froze. The computer did restart once and I was able to retreive a "log" which I have pasted below. After if froze for the second time it restarted once using verbose mode and froze almost immediately. After holding down the power key to shut it down and then restart; I received the same kernel panic after the Apple logo and spinning gear which put me right back to square one. Now the computer will not boot via any method. It freezes at the end of verbose mode which forces you to hold down the power button to shut down. I also read that poorly seated ram may cause this issue, but I removed and installed the ram multiple times. I even purchased new ram from Other World Computing (Mac Sales) 6 GB, but that did not make a difference. I think I may see six possible problems on the verbose screen mode, five errors and one warning; I will type them out here:
1. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
2. SMC: :smcReadKeyAction ERROR: $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
3. SMC: :smcInitHelper ERROR: MMIO regMap ==NULL - fall back to old SMC mode
4. WARNING - ACPI_SMCCtrlLoop: :initCPUCtrlLoop - no sub-config match for MacBookPro4,1 with 8 p-states, using default stepper instead
5. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key MOTP (kSMCKeyNotFound)
6. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key BEMB (kSMCKeyNotFound)
I was hoping that someone could read my log to ascertain wether or not they see a problem that stands out. I was also hoping that someone could tell me if verbose mode provides any information that may be wrong with my computer. I just hope that someone can give me some insight as to what may be wrong with my computer. If it is the hard drive I will easily replace it, but I want to make sure that is the problem first before I waste money on a hard drive or anything else. Please let me know if anyone requires any other information from me.
Thank you!

I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card. I also was well aware that Apple offered a replacement program that ended in December of 2012. I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store. I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no. He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime. When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board. I asked myself, how can a flawed hard drive cause the screen to act funny.
nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses." I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it. I guess I will look into purchasing a new machine when I have the funds. Again...thank you both!

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

OR use this method
1. Press-hold the Home button (big circle below the screen)and the Sleep/Wake button (on top of the iPhone) simultaneously.
2. Continue holding both buttons (Ignore the"Slide to power off") until the iPhone shuts off and begins to restart.
3.You may let go when you see the silver Applelogo.
Thats all Folks!!

My computer won't turn on. When the charger is plugged in it flickers between yellow and green

I was using my MacBook pro felt it charging and asleep for 4 hours. I came back and it won't turn on. When the battery is plugged in it flickers between yellow and green.

First thing to try would be resetting the System Management Controller. If that doesn't fix it you are probably looking at a hardware issue. Carry the computer in to an Apple store or service provider, or call Apple to set up service.
Best of luck.

HT4623 just updated my iPhone 4s to ios6, now my phone won't turn back on. The apple logo comes on and sits then shuts off. I have held down the home button and on/off switch several times to reset, but same problem persists.

Place iPhone on Wall Charger for at least 10 minutes. Then keep on charger and Reset, hold both home and power buttons until the iPhone begins to start, this can take about 20 seconds of holding both buttons while on charger. If still problem, open iTunes 10.7 on computer, connect iPhone to computer with USB Cable, hold both home and power buttons for about 20 seconds until iTunes recognizes iPhone in Recovery Mode, then click Restore button of iTunes. If still problem, try DFU Mode Restore, here are the steps. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power buttons, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes. DFU Mode can be difficult to enter sometimes, just keep trying. DFU Mode is a black, blank screen with iTunes saying Recovery Mode. If still problem and there is Warranty or AppleCare make Genius reservation and take to Apple for resolution.
