EMac won't reboot

One of the emacs in the lab froze up using Safari. I tried to force quit the program. It didn't respond. I tried using ARD to reboot the computer. It showed up as off line. I used the power switch on the side. I heard only a faint tone and then three chimes. The power light shows up for ten seconds and then flashes four times. I reset the pmu. I can't reset the pram or boot from a disk.

Mr. B,
Four beeps / power LED flashes indicates bad RAM detected during the power-on self-diagnostics; refer to Power On Self-Test Beep Definition.
It might be worthwhile pulling the RAM on the Mac in question and re-seating the memory chips; refer to eMac - Do-It-Yourself.
If you have third-party RAM mixed with Apple-supplied RAM, try pulling the third-party RAM. (You'll need to pull third-party RAM before taking it to an Apple Authorized Service Provider [AARP] anyway.) Reputable third-party RAM vendors will generally replace bad RAM as long as you own the computer.
If all the RAM is from from Apple, contact an AARP or AppleCare with the eMac's serial number (from th elabel inside the optical tray door) handy, describe the beeps, and ask them to send you replacement RAM.

EMac won't reboot after 10.4.7 combo update

Help! I just installed the 10.4.7 combo update, and my eMac won't reboot. I get to the gray Apple startup screen (no progress dial is displayed), and it won't go any further. Safe mode doesn't work either. Can't get the CD drawer open to boot from CD.
I must have goofed, because I had the iBook connected to the eMac over the AirPort hub at the time it was updating, doing a backup. (The iBook was the client.)
The same update worked fine on my iBook. No issues there. Would appreciate any help!

Hello,
I just went through all this stuff with another guy here.
We did eventually get his machine running again (it took a while, but we hit on the right answer for him).
But, rather than repeat the long and lengthy list of things we tried, I'm going to provide you with the link to our discussion.
http://discussions.apple.com/thread.jspa?messageID=2641346#2641346
At the beginning, it will sound more like a complaint. But, it does evolve into a trouble-shooting and repair discussion.
I would recommend reading through the messages from the beginning, and working your way through the discussion.
As you proceed, try each of the ideas on your machine.
With any luck, one of the less dramatic options will work for you.
I hope you find an answer in there.
If you try all that, and still nothing works, then let us know.
I am not trying to "brush you off". But, it was an exhaustive process fixing his machine. And, everything I could offer to you to try would be listed in that discussion.
So, rather than re-invent the wheel (so to speak), I thought it might be best to just have you try the trouble-shooting steps we discussed there.
Let me know how that works out for you. And, let me know if it works.
If it doesn't work, let me know what steps you did try so that I don't suggest something you have already done.
I do hope this helps.

My emac won't reboot or start up from the install disk

My emac has been freezing soon after startup. I managed to use the mouse click to get it to open the disk drive door on startup, and then inserted the install disk and restarted.
Sometimes I've tried holding down C, which does nothing;
Sometimes I've been able to get it to start up long enough to click on the install disk and click restart, but then it just restarts and ignores the install disk;
And sometimes I've tried going to system preferences and changing the start disk.
None of these work. Ideas?

Are you certain you're using the OS X Install CD or Tiger Restore DVD (whchever came with your Mac)?
Have you disconnected all peripherals other than Apple keyboard and mouse?
Does the Mac Start Up in Safe Mode?
Holding the 'c' key down at startup requires a wired USB keyboard, and you must keep the 'c' key down until you see the gray screen with the Apple logo. You can also use the option key; see Startup Manager: Select a Startup Volume
Holding the mouse button down as the Mac starts up will force-eject all removable media and open the optical drawer.

My eMac won't go to sleep

My eMac won't go to sleep automatically. I have to do it manually. I've tried reseting energy saving to default. No change. Also my screen saver doesn't appear. The screen will just go black. So I endup with a black screen while the computer just keeps running. It is very annoying. Anyone had the same problem?

This is for a Mac that won't sleep.
Here is KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB card.
Also, here is Apple KB article TA2469 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Allan Jones says "sometimes there is Network activity: launch System Preferences > Energy Saver > "Options" tab and uncheck "Wake for Ethernet network administrator access."
Good Luck!  DALE

EMac won't stay asleep

All of a sudden, my eMac won't stay asleep. I've turned off all the settings in Energy Saver (including the Wake options for modem/LAN). I also have no USB or Firewire connections.
I've repaired permissions, optimized system, cleaned caches, and zapped the pram.
I've tested on/off my LAN. I've also tried unhooking my mouse and keyboard.
Here is the system and console log after I put it to sleep:

Help! My Mac mini won't reboot

Hi. I posted yesterday (in the Safari forum) concerning a problem I was having with Safari 3.0.4 after updating to 10.4.11. Basically, it wouldn't run. Anyway, I did a bunch of searches on the Web (including this forum) to try to figure out what to do. One piece of advice was to move System/Library/Frameworks/ApplicationServices.frameworkapplicationservices.fram ework to the desktop.
Well, I did that, and things started acting weird. I tried to copy it back, but the process just seemed to hang. So, I did what I thought was obvious but was apparently a bad idea: I rebooted. Guess what--now my Mac won't reboot. I just get a perpetual hourglass.
I tried doing repairs with Disk Utility, but that didn't fix the problem. I also did a superfluous Hardware Check from the same OS disk, and that turned out normal.
So, what's the solution? A visit to my friendly Apple dealer for some service? Or am I just permanently hosed with no recourse? Please let me know what I can do. Thanks!

Sadly Apple stores are rarely set up for the purpose of completing backups and securing data, so that's not something you can rely on them to do. Some Apple approved service providers are better equipped for doing this, but in the end, it's not a good (or comfortable) proposition to trust your data to anyone else, and the more important that data, the less good, (or comfortable) it is if you have to.
The risk of data loss is relatively small in this situation - particularly if you ran 'repair disk' from disk utility and it reported no errors. That generally would indicate the drive is healthy and there are no indications of damaged data or file structures. Still there is always a risk!
In your situation, if I were faced with the knowledge that I was going to be buying an external drive for future backups, I'd be inclined to buy it now (selecting a firewire-connected hard drive of at least the same, if not much larger capacity than the internal), and then run Disk Utility again, this time (carefully) selecting the external drive, partitioning it under the Apple scheme, then formatting it (MacOS Extended (journaled) and then installing MacOS on it from your 10.3 installer. After that, I'd boot to it by holding down the option key during startup, then selecting the external drive from the list that (after a couple of minutes) should appear. Then the internal drive will be mounted on the desktop under the external which has booted the system. That will give you to option to copy your iPhoto and iTunes libraries to the external drive, and thus secure your data.
Once that's done, you can reboot to the install disk and basically even erase and install, because your data is safe on the external drive!
After the internal is set up again, and fully updated, it then becomes a simple matter of moving your data back to it, and then erasing the external once more, and setting up your backups with SuperDuper! or CCC.
It might sound like a bit of messing about, but that would keep your data safe in your own hands!

MacBook Pro won't reboot. Get spinning circle even after hard drive replaced at Apple Store

MacBook Pro won't reboot. Have to reinstall OSX each time I shut down in order to get it to start up. What could be wrong? I had the hard drive replaced already.

You shouldn't be using the disc at all. I thought I had made that clear. Boot from your recovery partition and run Disc Utility. If you get the same result -- the internal drive can't be repaired -- then you should consider replacing it. No storage device can be trusted, in my opinion, after throwing an error like that. But whether you choose to replace it or erase it, you have to get the data out first.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

MSI Z87I Won't Reboot or Shut DOwn

My new system won't shut down or reboot from the OS (Ubuntu 14.04) or from the BIOS settings, i.e. Settings -> Save & Exit -> Save Changes and Reboot will not reboot the system. All my peripherals will turn off, but the fans stay on and the only way to power off the system is to long-hold the power switch on the front of the case or turn off the power at the PSU.
There is ONE case in which the system will reboot. If I go to Settings -> Save & Exit, choose "Restore Defaults" and then select "Save Changes and Reboot," the system will reboot one time, but it won't reboot or shut down after this.
I'm already on my second MoBo since I thought it was a MoBo issue.
Specs:
SSD: Patriot Pyro 60GB
Memory: 2x PNY 4GBH2X02E99927-16-H
CPU: Intel Core i3-4150 LGA1150
PSU: Thermaltake TR2 500W
I've tried reseating the MoBo as well as testing it outside of the case with no luck.

Ah, thanks! Got it.
It looks to me like that is a different link to the same program, as when I downloaded it I got 'MSIHQ Tool 1.25g Installer(1).rar' as the filename, since I had just downloaded 'MSIHQ Tool 1.25g Installer.rar' from the link I posted (or perhaps from a page pointed to by that page, I've already forgotten where I got it...)
I notice that the '180' file has a batch file that runs 'fpt'. Am I supposed to run that batch file, or run 'efiflash bios.bin'? (Or both if this is the first time I've flashed the motherboard)

em nope, its the same program. (1) is auto renamed because the same name was already existing in your download folder

no need to run anything
just let the tool to prepare the USB key then boot from it
when this menu appear select option 2:
1 Run Memtest
2 Proceed with BIOS Update
3 Flash back to prevision bios
then press any key after read some safety instructions
then when asked if you want to Run Memtestx86, answer with "N"
then flash will start and will be asked for reboot when its done
you no need to type or run anything manually, its tottaly automated

Older mac mini won't reboot from Install DVD?

I've passed on my 2006 era mac mini to my daughter. We can't seem to get to a factory settings because it won't reboot from the install DVD. It keeps cycling through to the normal reboot.

Could be damaged disks.
BestBuy sells disk repair kits.
But for about the same price as disk repair kit, you could call 1-800-676-2775 and give them the unit serial number and pay shipping/handling fee for replacement.
Assuming it is bad disks.

Clustered Oracle VM server 2.1.2 won't reboot or hangs

Has anyone experience with clustered Oracle VM servers 2.1.2 seem to be hang or won't reboot until the server is power reset?
Every time I reboot the master pool server, the server seems to be hung or won't reboot. To solve this problem I have to power reset the server or reboot the other server in the server pool or vice versa. This is not what I wanted. What do i need to do to have a smooth reboot of master server pool without reboot the other server in the server pool?
Thank you in advance.

Toshiba Tecra M1 - Won't reboot

Hello @ll
This is my first post on this forum. I write from poland, so forgive me for my poor english.
I have a problem with my old laptop (Toshiba Tecra M1). Computer won't reboot. After the Arch installation everything was fine, command init 6 was working correctly. When I was doing installs and configurations (adds daemon's to rc.conf, modifying fstab, install KDEmod etc.) i was rebooting system to see how it works. I don't know when, but after 3th, maybe 4th reboot system won't boot. I can see the screen which contains information about closing daemons, but after this listing I can see only black screen, computer stops and nothing happens.
Thanks for any advices
Last edited by pmd (2008-08-14 11:59:16)

On this virtual way nobody can say for sure what the problem is. As Joe already wrote it is hardware related issue and it should be checked by technicians. Fact is that this Tecra M1 is pretty old notebook model (I had it 8 years ago) so I think repair is not a option.

My Ipad 2 won't reboot. The little circle keeps going round but that's all, it won't boot. nothing happens when I press the button on the top either. Please help.

After you hold the power and home buttons at the SAME time until the Apple Logo appears (ignore the red slider to shut down) then let go of both buttons and you don't need to do anything else. Your iPad will restart all by itself. Just be patient, but leave your iPad alone after the Logo appears.
