Imac not starting up properly

When I restart my iMac it starts with a black screen and the word 'root' at the top left corner of the screen. What do I type in so that it takes me to the login page?
If anyone can help, greatly appreciate it...

Yeah it worked before...I forgot the admin password and the only way to change it was to reset it using the installation disk. I cancelled it before it completed and when I restarted the computer the black screen appeared.

Hi Everybody,
I am quite new in BEA product, actually with weblogic integration. I get an issue when I tried to start Weblogic integration.
I used Weblogic integration 8.5 on my Windows box and JDK 1.4.
When I tried to start it I get the folowing error:

Do you have some idea why I get this error while starting the server?
Thank you in advance!

First you can start witht he example server, after installation go to start menu --> example--> launch the examples. which will create a sample domain and brings up the server etc., If you want your own domain, using configuration wizard create a domain(follow the steps mentioned in edocs.bea.com) and bring up the server.

Oracle Database Not Starting Up Properly

On VMware there's a known issue with Oracle databases on a Windows client not starting up properly all the time and a manual startup using oradim -start -sid <whatever> is required to get it fully running. I kinda figured that I wouldn't run into the exact same issue on Oracle VM. I created a brand new Oracle VM Windows 2003 32-bit server, installed the Oracle drivers for paravirtualization, and whammo, the problem is still here. I didn't find anything in this forum about the database not starting up, so I'm wondering if others are running into the same problem and how to resolve the issue. Thanks a bunch for your help.

Hmmm, doing it several time, and never seen such issue. Which "known issue" and by who are you talking about ?
I created a brand new Oracle VM Windows 2003 32-bit server, installed the Oracle drivers for paravirtualization, and whammo, the problem is still hereI'm sure, you miss something somewhere in the config. Right now, you're on supported configuration, you could either raise a SR to the support, or get help from your peer on Oracle Database General forum.
Ah, but it's not a Windows issue. On a non-VM Windows box the database starts just fine all the time. Again, this is a known issue acknowledged by Oracle on the VMware side, I'm just surprised it exists on the Oracle VM side.Again, give more details about this "known issue". Never heard about that, eventhough I've been around for years.
I was afraid you were going to ask that. I'll have to search for it again, but I think you can do the same as well....Well, I doubt you could find a Metalink note about Oracle on VMWare. So far, Oracle has always refused to support database on OS virtualized on VMWare (or any VM software other than Oracle VM). Based on that, you could be sure, your "known issue" is not an issue on Oracle VM.
If you want more help, again, give more details about your issue.

When you turn on the ipad2 it does not start up properly. The rotating disk that happens when you turn off the ipad appears after the apple logo comes up

When you turn on the ipad2 it does not start up properly. The rotating disk that happens when you turn off the ipad appears after the apple logo comes up during start-up and stays there for ten minutes. Then, the ipad will start up properly.

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Intel iMac not starting...please HELP!!!

Hey all,
Well I just arrived to my new dorm room in college with my one week old iMac and I'm encountering some serious problems....
I plugged the computer in while it was on my desk, with other hardware attached into a surge protector and it worked fine for about two days. Today I recieved some new furniture so I had to unplug the computer to move things around....I unplugged it and placed it flat (screen side up) on a pillow.
I plugged it back in with a new surge protector, connected the hardware and pressed the button...didn't start. The printer, the speakers, everything else had power so it wasn't a faulty power strip...just the computer wouldn't start. I then did the following:
1. Tried different connections on the same surge protector
2. Switched back to the old surge protector
3. Plugged the computer w/o external devices into the wall directly
4. Tried it as described above into a different wall outlet
And nothing has worked. I'm going to call Apple in the morning, but as you can imagine with the year starting this is the last thing I need. I'm using my old G3 iBook at the moment to get by, but what has happened to my brand new iMac? Thanks for your help

DIRECTLY from the iMac Help site:
The System Management Controller (SMC) is a chip on the logic board that controls all power functions for your computer. If your computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including:
* Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.
* Handling system resets from various commands.
* Controlling the fans.
Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues in which your computer is unresponsive—in these situations, restarting your computer will generally suffice. If your computer isn't responding, perform these steps one at a time, in this order, until the issue has been resolved:
1. Force Quit (Option-Command-Escape).
2. Restart (Control-Command-Power).
3. Force Shut Down (press the power button for 10 seconds).
Resetting the SMC can resolve some computer issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth. If your computer still exhibits these types of issues after you've restarted the computer, try resetting the SMC. To reset the SMC on an iMac (Early 2006), iMac (Mid 2006), or Mac mini (Early 2006):
1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2. Unplug all cables from the computer, including the power cord and any display cables.
3. Wait at least 15 seconds.
4. 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.
5. Press the power button on the back to start up your computer.
The iMac (Early 2006) and later models do not have a button on the main logic board for resetting the SMC, which eliminates the need to remove the computer's cover to reset it (as required for some earlier models).

[Urgent] MacBook Pro is not starting up properly

I was recently doing work on photoshop and my MacBook Pro's screen went dark but the computer was still running. I restarted it and it was stuck on the grey screen after the apple logo showed up so I restarted again and notice the screen with the apple logo was tinted blue with small horizontal lines. After failing to start up properly multiple times I started it up in safe mode which worked but the were vertical blue bars then entire time. I later was able to start the computer up normally but the screen would glitch out and freeze after a short period of time. Soon even safe mode would glitch out if I did many actions quickly like open the dashboard multiple times or change spaces quickly and the screen would become a series of pixel wide blue and black vertical lines. What is wrong with my computer and how can I fix this so that I can start it up normally and resume work that needs doing urgently.
Here is what I have tried so far:
Verifying the disk in safe mode and nothing was reported wrong
Repairing disk permissions in safe mode
Resetting PRAM
What can I do to fix this problem short of a full wipe or trip to the apple store as I am currently abroad. I also do not have an install disk on me.

i had same problem...
but
Macbook Pro is FIXED!!! FOR FREE!!! under warranty!!! Woooop Woooop!!
Macbook pro would not boot light on front and hardrive noise but nothing on screen...
So i took it to apple store and got seen by the head genius (hmmm).
And because it wont boot and they have the diagnostics to see if it is the graphics chip on a usb drive he could not confirm that because it cant read/start the drive... and told me he could do nothing and it would be a new logic board and cos i am out of warranty and applecare it would be £700.
Morning!
So i took it to the "mac and pc centre" manchester a certified reseller service centre for a second opinion and see if they could repair for less...
So they confirmed the logic board needed changing but they asked apple if i could be done under warranty and apple said thats fine so its here after 2 days in the shop all repaired...i am happy...
Still gonna get a mac pro soon though..
Cheers.. woop woop

Why does my intel iMac not shut down properly?

On Shutdown, the screen goes black, appears to be shut down, but start button will not start unless you hold it in for several seconds. After machine boots messages says not shut down properly. Does this everytime. Has done it since it was new a year ago. the screen is black, but the button will not start the machine unless you hold it down, then you get the message. Have never seen anything like this. It is as if the machine thinks it is still running.

I'm not sure that a normal shutdown followed by turning off a power strip will reset the SMC. Power strips just switch off the "hot" leg of the power but do not interrupt the "cold" (neutral) leg or the "earth" (ground) connections. It may be that the SMC senses the cold-to-ground path or something like that to do a reset.
It may also be that the Mac hasn't actually shut down completely when you switch off the strip. You might try waiting a minute or two before doing that to see if it makes a difference, or listening carefully for any noises coming from the Mac after the menu shutdown before hitting the power strip switch.
I sometimes use an old veterinary stethoscope to listen for sounds coming from Macs for troubleshooting purposes (although never yet with a MacPro) & have noticed that the screen goes dark a little before everything else is fully shut down.

HELP! iMac not starting up ... blue screen with folder and blinking ?

my imac is not starting up. when i turn on the computer, i get a blue screen with a blinking folder icon of the finder and a black question mark. i can't move anything or type anything.
i have tried powering down and powering back up with holding down the option key, but all i get is a screen with two buttons with a curved arrow and a straight arrow. however, i can't click any of them!
i don't know what to do and i need major help! can anyone help me? i don't want to spend the $49 again for a simple fix.

For starters, follow the steps in this Apple KB Article Post back if you have any questions or things still don't work out.

IMac not starting up (no chime and no USB power)

Hello,
My neighbor's computer is experiencing some problems: it does not start (the screen stays black, no startup chime, but the fans run, as does the hard disk. Also, neither the mouse or the keyboard seem to be powered (no light), so the computer doesn't even come to loading the EFI). The model is an iSight iMac G5 20'' (EMC=2082).
I have tried usual commands (reset PRAM and reset the SMC). Also tried with no device connected. (well, if something so trivial than all these tips did the trick, I wouldn't had to ask here ).
So, without keyboard, I couldn't even try special modes (safe, target disk, start from CD, etc), should the Mac be able to start in some mode. I have then decided to open the iMac (well, the warranty is way out, so nothing is lost). I have never seen a so-hard-to-open Mac, by the way (something was likely blocked).
I'm thinking of 4 possible causes for the problem:
-the hard disk could be damaged. It was malfunctioning some days ago. I assume it could come to a point where the logical board of the disk is failing;
-the RAM is an obvious possible cause;
-the CPU is also obvious;
-another component on the main board/logic board.
-I have forgotten a 5th point?
Well, I tried with unplugging the hard disk, and it had no effect, so it's not the HDD. I'm puzzled for the remaining ones (not knowing the iMac enough is a cause).
First, about the RAM, it seems the RAM slot is empty, so the actual RAM is somehow built-in (I haven't seen something seeming like usual RAM bars), so, if I can't remove the RAM, how can I test whether it's damaged or not?
Then, the CPU. There are 2 of them. So I thought I may take one out (and then the other one) and see whether the Mac starts. Well, I can't figure out how to remove the CPU cooling piece (there are just 4 "buttons" that can be pressed but nothing happen). I prefer asking here first, not removing the entire main board without advices.
Lastly, if it's the main board, I know I won't be able to do much. I have read there are LEDs to possibly diagnose power issues, but I don't see them (no LED is showing light, it seems). I'd like to test my other assumptions before thinking the main board is the cause.
Else, is there something I could try I have forgotten?
P.S: sorry for my (possibly) bad english, and the troubles of explanation; it's not as easy when english isn't the native language. I just wanted to mention that I have already repaired computers, so don't hesitate to tell me complicated answers.
Thanks in advance for your help.

Hello,
Anic,
You can't remove the CPU nor remove/replace the RAM… Really a bad model!
Yes you have to think of it more like a laptop. The only models w/ removable CPUs were the Towers.
Which explains why I thought CPU were usually removable (I have mostly used towers except the original iMac, before).
Thanks. I indeed never touch a board when the computer is plugged.
Hee hee I did since I was used to working on the ALS model where the power supply is enclosed.
Even on an enclosed power supply, I'd not want to touch some kind of board. Well, perhaps it's just me.
Actually, it's the info about which info I need that I'm looking for
After having tried what I could, the remaining bits seem locked (unlike other models).
Not sure what you mean here?
Well, after re-reading myself, I agree I don't really understand either
I meant that I have already tried as much as I could, but the remaining bits (so to mention, the RAM and CPU, mainly) can't be tested. So, I'm looking for testing other parts of the iMac (perhaps there's other things that can be tested, like flashing the EFI).
I'd like to hear from you that the built-in RAM can't be tested, please (to clear my assumption).
the external screen adaptor..(if it wasn't optional, then she does not know where it is).
Well it looks like this. It's pretty standard. Every iBook had one for instance.
http://www.synaptech.com/catalog/images/922-4554.gif
In fact, all the laptops I have seen have that kind of adaptor (although they may slightly vary from models to models), but I thought it was only for laptops (which, as they are easy to move, may have different available screens). Now, does it also apply to iMacs?
I have a question regarding this: I guess the LED3 is concerning the whole graphic card, not just the built-in output, right (in other words, not just about the "main" display)? So I doubt an external screen would make any difference since the LED3 is off (tell me if I'm wrong).
Well what the manual says is:
"LED 3: Indicates that the main logic board has established communication with the LCD display."
So if that's not light then the graphics chip is not communicating with LCD panel.
Fine, but can the graphics chip still communicate with the external port, even if the LED3 is off?
(sorry for having been unclear)
So you did a SMU reset like this:
"Resetting the SMU (System Management Unit)
1. Unplug all cables from the computer, including the power cord.
Wait 10 seconds.
2. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
3. Let go of the power button.
4. Press the power button once more to start up your iMac G5 (17-inch iSight).
Hmm… Not sure about step 2. The "simultaneously" part may not be what I did (I actually tried two things:
1: plugged back the power cord, then (after that) pressed the power button
2: while still unplugged, I pressed the power button (held down for about 5 seconds), then released it and plugged the power cord back.
Do you think I should press the power button while the iMac is still unplugged and keep the button pressed while I plug the iMac (then release the button after I have plugged it)?
If that doesn't help you really need that Mini VGA to VGA adapter so you can plug in a standard VGA monitor and check out the output of the graphics chip (GPU).
I'm glad you mentioned every iBook has one, since my sister has an iBook
I'll ask her.
Since it's not communicating with the LCD it could be a cable problem.
I'm doubting of that, because I'm sure the Mac does not boot at all (not just a blank screen, but also no power on USB ports).
Also you should read through this site:

Which concerns the "capacitor plague". I'm sure you're aware of this. We had 30 Dell P-IVs that had this problem and those logic boards had a ton of lytics on them.
Hmm… What a charming surprise
Well, I'm indeed aware of this (it hasn't happened to me yet, fortunately).
Thanks for the link.
As to the rest of your questions, answer this set first.
Fine, I follow the guide
Thank you.

IMac not starting up and no chime

Hello,
My neighbor's computer is experiencing some problems: it does not start (the screen stays black, no startup chime, but the fans run, as does the hard disk. Also, neither the mouse or the keyboard seem to be powered (no light)).
I have tried usual commands (reset PRAM and reset the SMC). Also tried with no device connected. (well, if something so trivial than all these tips did the trick, I wouldn't had to ask here ).
So, without keyboard, I couldn't even try special modes (safe, target disk, start from CD, etc), should the Mac be able to start in some mode. I have then decided to open the iMac (well, the warranty is way out, so nothing is lost). I have never seen a so-hard-to-open Mac, by the way (something was likely blocked).
I'm thinking of 4 possible causes for the problem:
-the hard disk could be damaged. It was malfunctioning some days ago. I assume it could come to a point where the logical board of the disk is failing;
-the RAM is an obvious possible cause;
-the CPU is also obvious;
-another component on the main board/logic board.
-I have forgotten a 5th point?
Well, I tried with unplugging the hard disk, and it had no effect, so it's not the HDD. I'm puzzled for the remaining ones (not knowing the iMac enough is a cause).
First, about the RAM, it seems the RAM slot is empty, so the actual RAM is somehow built-in (I haven't seen something seeming like usual RAM bars), so, if I can't remove the RAM, how can I test whether it's damaged or not?
Then, the CPU. There are 2 of them. So I thought I may take one out (and then the other one) and see whether the Mac starts. Well, I can't figure out how to remove the CPU cooling piece (there are just 4 "buttons" that can be pressed but nothing happen). I prefer asking here first, not removing the entire main board without advices.
Lastly, if it's the main board, I know I won't be able to do much. I have read there are LEDs to possibly diagnose power issues, but I don't see them (no LED is showing light, it seems). I'd like to test my other assumptions before thinking the main board is the cause.
Else, is there something I could try I have forgotten?
P.S: sorry for my (possibly) bad english, and the troubles of explanation; it's not as easy when english isn't the native language. I just wanted to mention that I have already repaired computers, so don't hesitate to tell me complicated answers.
Thanks in advance for your help.

This page does say some RAM is built-in: http://support.apple.com/kb/HT2266
It explains why the RAM slot (which there is just one) is empty as there is not further RAM installed.
No startup chime means no usable RAM was encountered during Power On Self Test.
It may also mean some other problems, if I recall correctly (for instance, a dead CPU will prevent the chime, because the chime indicates all has passed).
I have the feeling that we aren't talking about the same model, because, according to:
http://support.apple.com/kb/HT2341
the LED should blink when there's no RAM. In my case, the LED stays on.
Exactly what model of iMac is this?
It's an iMac third generation 20'' isight (put the terms in the order you want ). EMC is 2082.
Thank you for this answer. Does not solve my problem but is useful in progressing.

IMac froze, and now will not start up properly

I left my iMac for about half an hour, and when I came back, it was completely frozen, and I had to shut it down by pressing the power button. I turned it back on, and this is what happened:
I heard the usual chime, and the grey screen popped up. However, the screen then went black, and then the grey screen popped up again. After a few seconds of solid grey screen, a little icon appeared in the middle of the screen. It looks like a little folder icon, and it alternately flashes the face from the Finder icon and then a question mark over and over.
I tried resetting the SMU and holding the Command-Option-P-R keys before the grey screen pops up, but to no avail. Any suggestions?

This exact same thing just happened to my girlfriend's iMac G5 on July 11th. After taking it to the Apple Store Genius Bar, we were told that it was a hard drive failure. they booted the computer off their external hard drive with some kind of utility program. the iMac's hard drive did not show up as a drive at all. we were told, there was nothing they could do about it. we could go to a hard drive data specialist who could attempt to extract the data on the hard drive but it would cost up to $1000, but even then the chances of getting data back are not guaranteed. we basically need to get a new hard drive.
this is lovely... for a computer that is a year and a half old, you would expect a little more longevity and reliability in it's components. my old 450MHz G4 tower, that's like 8 years old, has never caused me any problems except for being slow in speed. makes me reconsider wanting to replace my old G4 with the next iMac release.
does anyone have any other suggestions and recommendations that won't cost a thousand dollars in recovery services? thanks!
