Intel iMac sleep problem, need help !

My 17" Intel iMac has sleep problem past few days.
I use the Ctrl+Eject on the keyboard to put my iMac to sleep and it only needs 3 to 5 sec before.
But now I use same method, it got 30 sec. to sleep; same result thru Apple menu>sleep.
Used Onyx & repair permissions, still no change.
Anyone know what's the problem, how to fix it?
Plz help!
Thx!

Danlam,
A simple SMC (System Management Controller) reset is known to resolve a lot of sleep/wake related issues.
Here's how to do the reset:
- From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
- Unplug all cables from the computer, including the power cord and any display cables.
- Wait at least 15 seconds.
- Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
- Press the power button on the back to start up your computer.
Follow this link to the Apple Article that describes the SMC and how to reset it in more detail: http://docs.info.apple.com/article.html?artnum=303446
Hope this helps you out.

Major imac blueberry problem, need help

Hi, someone came to me with an imac that had a black screen. I hooked it up to a monitor and was able to see the HD and it seemed that they had updated the software to OSX and I suspect not the firmware. I tried checking using OS9 and the imac starts to come on and then immediately stops, spins up for 5 seconds and then shuts down. if I press the start button on the front the light will come on but nothing happens. Is there a way to get this machine to come on and stay on long enough to update the firmware? I have the external monitor plugged in but nothing happens, it doesn't stay on long enough to do anything. I've reset the power manager but no luck.
Any help would be appreciated.
Thanks

Hey Derek,
Yup sounds like the classic firmware trap. Here's the classic site to solve the problem:

IMac - sleeping problem

Hi Guys,
i have new model of iMac (Late 2012 with 10.8.3) and i have in my point of view problem with "deep sleep".
1) after about 60 min (pmset -g, timer - autopoweroffdelay14400) away from keyboard iMac sleeps "deep sleep".
2) no possible to wake-up with keyboard or mouse
3) only power buttons work
4) iMac needs two login, first for FileVault and second to the System (why ? on MacBook Air you need only one)
5) all applications starts again (why ? The new start take 1 or 2 minutes :-((( On MacBook Air all applications starts where im finished, no restart, etc. I can working instantly without waiting)
6) no applications (for example iTunes) can't prevent iMac from this type of sleep. If i listen to iTunes (music play, using remote to change albs, etc.) and after about 60 minutes away from the keyboard, iMac sleeps (why ?)
7) in this type od sleep can't use remote desktop from through internet (use AirPort Extreme), no possible iMac to wake up (you need to push power button, why ?)
8) in this type od sleep no application can't iMac wake-up. For example remote from iOS :-(
What i try to fix my problem:
1) in pmset set sleep to 0, iMac now can wake-up with keyboard and mouse
2) restart SMC and PRAM https://discussions.apple.com/docs/DOC-3603
3) repair disk permissions http://support.apple.com/kb/ht1452
4) delete sleep file http://www.maclife.com/article/howtos/how_remove_diskhogging_sleepimage_file_you r_mac (BTW: my sleep file have only 2G and i have 16G RAM)
5) in pmset set autopoweroff to 0
6) in pmset set hibernatemode to all modes
7) in pmset set sleep to 0 (i try to sleep to never, but iMac sleeps again)
8) in pmset set setautopoweroffdelay to 0
Nothing helps :-(
Do you have any recommendation ? In next steps i try to erase whole system and install new vanilla and will see :-(((
Thank you guys ! Im so tired :-)))

Have you tried "fsck -fy" repairs under single-user mode?
http://support.apple.com/kb/ht1492
Reboot and hold down the Command (Apple) and S keys before the grey screen appears.
Wait for the command prompt, then type:
sbin/fsck -fy
Repeat that command until "file system was modified" is no longer reported back, type:
reboot
Or try Titanium Software's "Onyx": http://www.titanium.free.fr/downloadonyx.php (not affiliated)
Check your preferences for corruption: Under the "preferences" tab, within the "Verify" tab.
Hope that helps.

BOOTABLE Firewire on Intel iMac - my story, need answers...

Just got the new Intel iMac in today. Need to be able to boot from a Firewire drive. Connected FW drive, it shows up on desktop. Erased using Disk Utility (the version that came installed on the Intel iMac). Re-booted from the iMac system DVD. When it gets to the screen to choose which drive to install on, it won't allow me to install on the FW drive. When I click on the FW drive icon, I get this message:
"You cannot install Mac OS X on this volume. Mac OS X cannot start up from this volume."
I've tried different drives, and different FW cases. It states in the manual that came with the iMac that one of the uses of the Firewire ports is to allow booting the iMac from an external hard drive. So, what's the trick? Does it require a certain type of FW case, or drive, or firmware, or formatting? I'll keep testing, but if anyone knows the answer, HELP! Thanks.
BTW, I haven't done much on the iMac yet, but the speed in just launching programs is AWESOME! Apps launched and on the screen in less that one bounce in the Dock!

Tallan - I've tried Mac OS Extended, Extended (Journaled), Extended (case-sensitive), and Extended (case-sensitive, Journaled). And I've tried all those with the OS 9 driver installation on and off.
I'm going to try doing a bootable back-up using Synchronize Pro, which is what I've used for a long time on previous Macs. But there should still be a way to do a clean install from the original DVD.
Glorfindeal - what "special boot partition" are you talking about? Where is it? How do you do it?
Thanks for the feedback....

New intel iMac 20" problems...please advise.

I just purchased my first Mac last week. It is a 20" Intel iMac Core Duo with 2 gigs of RAM (apple RAM installed on site). After a day of use I began to have random kernel panics. Later, my system would shut down after two hours of use. I reset the SMC and that did the trick for 3 days. Now the top of the unit near the camera is getting hot and when I boot up from a shut down, the system does not boot to the desktop... it boots right into sleep mode, then takes about 15 to 20 minutes to wake from sleep mode where it goes into a couple of restatrs. Over the phone assistance has not been able to diagnose the problem and hardware tests all indicate that there are no problems. Furthermore, my work hours make it realy difficult for me to schedule time with a genius. I switched from a pc to a mac because I was tired of the problems with my pcs, but I am having far more trouble with my mac.

I will call apple when I get home. I have apple care for three years. The tech support has been good, but they are worried about the heat eminating from the area by the camera. Sadly, all the techs at my local apple store tell me that they are unfamiliar with the new intel iMac core duo and don't know what else to do. To top it all off, there was a popping sound from my mac and the the sound went out. I toggled the volume on the keyboard and the sound came back. I was told over the phone that I have to make an appointment with a genius to look at my system, but that they would only replace it if necessary. Sadly, my work schedule does not permit this. I wish I could just walk in and get the blasted thing replaced.

You know its kinda rude to derail XBenzinoFla thread with your own problems, make your own thread next time.
But to the both of you especially XBenzinoFla, try putting your ZVM in rescue mode and run scan disk to see if it hel

Intel Imac display problems

I have an old intel imac (17 inch white screen) bought just over 5 years ago. The imac has just 'died', the screen will not display anything. It will chime on starting up and I can hear activity but nothing displays on the screen.
I returned it to my local Apple store, upon investigation they said the graphics card had gone (£500 to replace) so I bought a brand new iMac a few days ago.
All of my data is backed to up an external hard drive.
I run a database programme on the old iMac called 4D, which has a huge amount of data stored in it (all backed up).
I have installed the most current version of 4D on my new Imac, but it will not open the data on my back-up (error message: data cannot be published).
I have installed my old original version of 4D from my original bought CDs, but again it will not read the data.
The guy in the Apple shop gave me instructions on how to link my old 'dead' iMac, to my MacBook Pro via a Firewire cable, and using Target Disc Mode, I should be able to access the dead iMac hard drive on my MacBook ... have just tried this and the dead iMac hard drive will not show up on my MacBook. It does not appear on the desktop as suggested by the guy in the Apple shop, nor does it show up in System Preferences > Start Up Disk as an alternative disc to boot from.
What I need to do is access the 4D database on the dead imac, so that I can export the data as a text file, to put into a new application on my new iMac.
Althought the data is backed up to the external hard drive, it is backed up 'in the database' ... and I need to EXPORT the data, which I cannot do unless I can open the database ... which I can't !
I'm going round in circles with this, so if anyone can please point me in the right direction it would be much appreciated.
Many thanks
Rock of Ages.

make sure you execute the instructions for target disk mode properly, because your screen is dead and you won't see the icon displayed.
see here: http://docs.info.apple.com/article.html?path=Mac/10.6/en/8443.html
you may have to hold the T longer on the deadhead mac.

Zen Micro problem need help

Today i was listening to music and my zen micro just froze while playing and no buttons could be pressed and the lock button wasnt on. So i took the battery out and rebooted the player but it froze at the creative screen. I went home and i went to recovery mode and tried to reload the firmware but it said erasing firmware for more than 2 hours. So then i tried a format but it said formating for the same amount of time. I need help please. Also, recently i've had problems witht the headphone jack. When ever i would stick it in it would sound distorted and i would have to move it around until i got it to a certain spot to hear it good again. If anyone else has this problem please tell me. One more thing i had returned my other micro zen in for hard dri've probems and this was my new one do u think if i have to return in (hopefully not) that they would accept it.

If the functions in Rescue Mode aren't working properly then you need to contact Creative Support.

If you have upgraded the RAM, the likely cause is upgraded RAM or some other hardware issue. Sources of RAM caused KP's are:
Failed RAM
Incorrect RAM
Unseated RAM
Start by removing all upgraded RAM and replace with the original RAM the computer shipped with and then test. If they KP's disappear you know your issue is RAM related to the upgraded RAM.

Another Infinite Login Loop Problem - need help badly

Hello. I need help.
When I start up my iMac (24 inch last generation model) I can't log into the OS. When I enter my password I see the default OS wallpaper (nothing else) then it kicks me to a blue screen then right back to the login. Same thing over and over. I've already ran disk utility off of the install CD to repair permissions, etc... but no luck. This even happens when I enter into safe mode. I'm running the latest version of the OS.
Can anyone help me?

Restore the bootable backup/clone or Time Machine backup. Without one, you have a difficult situation. First thing to try is boot with your install disc, run Disk Utility, and repair the disk.

Still stuck with the same old producer consumer weight problem need help

Hello All,
This is the problem I am stuck with right now.
I have two array lists one producer array list and one consumer array list denoted by a and b
P1 P2 P3 P4 P5
5 6 7 8 9
C1 C2 C3 C4 C5
2 3 4 5 6
Now we find all those producer consumer pairs which satisfy the criteria Pi>=Ci
We have the following sets
(5,2)(6,2)(7,2),(8,2),(9,2)
(5,3)(6,3)(7,3),(8,3),(9,3)
(5,4)(6,4)(7,4),(8,4),(9,4)
(5,5)(6,5)(7,5),(8,5),(9,5)
(6,6)(7,6)(8,6),(9,6)
Let us done each of them with Si
so we have S1,S2,S3,S4,S5
we assign a third parameter called weight to each element in Si which has satisfied the condition Pi>=Ci;
so we we will have
(5,2,ai),(6,2,bi),(7,2,ci)....etc for S1
similarly for S2 and so on.
We need to find in each set Si the the pair which has the smallest weight.
if we have (5,2,3) and (6,2,4) then 5,2,3 should be chosen.We should make sure that there is only one pair in every set which is finally chosen on the basis of weight.
Suppose we get a pair (5,2,3) in S1 and (5,2,3) in S2 we should see that (5,2,3) is not used to compare to compare with any other elements in the same set S2,
Finally we should arrive at the best element pair in each set.They should be non repeating in other sets.
Given a problem
P0 P1 P2 P3 P4
9 5 2 2 8
6 5 4 5 3
C0 C1 C2 C3 C4
we have So as (P0,C0) and (P4,C0)
assuming that the one with the smaller index has lesser weight PO is selected.In the program I have used random weights.from set S1 we select the pair PO,CO
S1 =(P0,C1),(P1,C1) and (P4,C1)
since P0 and P4 are already used in previous set we dont use them for checking in S1 so we have (P1,C1) as best.
S2=(P0,C2),(P1,C2) and (P4,C2) so we dont use P0,C2 and P1 and C2 because PO and P1 are already used in S1.
So we choose P4,C2
in S3 and S4 ae have (P0,C3),(P1,C3),(P4,C3) so we dont choose anything
and same in S4 also.
So answer is
(P0,C0),(P1,C1) and (P4,C2).
My program is trying to assign weights and I am trying to print the weights along with the sets.It doesnt work fine.I need help to write this program to do this.
Thanks.
Regards.

String l=(temp.get(j).toString());
if(l!="null")
System.out.println("l=" +l);
[\code]

In your example you selected the pair with the greatest
distance from the first set, and the pair with the least
distance from the second. I don't see how the distance
function was used.
Also it's not clear to me that there is always a solution,
and, if there is, whether consistently choosing the
furthest or the closest pairs will always work.
The most obvious approach is to systematically try
all possibilities until the answer is reached, or there
are no possibilities left. This means backtracking whenever
a point is reached where you cannot continue. In this case
backtrack one step and try another possibility at this
step. After all possible choices of the previous step,
backtrack one more step and so on.
This seems rather involved, and it probably is.
Interestingly, if you know Prolog, it is ridiculously
easy because Prolog does all the backtracking for you.
In Java, you can implement the algorithm in much the same
way as Prolog implementations do it--keep a list of all the
choice points and work through them until success or there
are none left.
If you do know Prolog, you could generate lots of random
problems and see if there is always a solution.

I want a new imac but i need to figure out which desktop macs i can upgrade later on in the future and to what extent.

Welcome to the Apple Support Communities
I'm not sure what your questions is. If you are referring to replace hardware of the iMac, the only things you can replace are the memory and the hard drive. The other things are soldered onto the logic board and you won't be able to change them

Urgent Problem, need help asap.

Hello everyone,
I'm sorry for the alarmist title, but I need help and I need it badly. Just last night, my macbook froze with nothing working. The mouse froze, the interrupt keys didn't work, nothing. I shut down the laptop, and tried to restart. I noticed a clicking sound coming from the lower left hand corner of the macbook. I'm assuming this is the hard drive.
What happens is that there will be two clicks happening in a rythmic fashion, and after 15 second of booting up, a folder will appear with a question mark on the screen. The only thing I can do is power it down. Can someone please describe what is happening and make suggestions?
The kicker is that I'm a college student studying in Denmark for the semester. The laptop is my only lifeline to back home. Please, any help is greatly appreciated.
Matt

You may have a disk failure or simply corrupted files. If you have a bootable backup that is working, then you can boot from it, erase your hard drive, then restore your backup. If not then do this:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If the drive is OK then you can reinstall OS X:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
