Totally stumped after power outage!

I have a G5 desktop running 10.5.4. It was in sleep mode and the power unexpectantly went out. Once power was restored and I rebooted, I am now unable to connect to the internet via ethernet or airport card, the hard drive says it has zero KB available, and I am unable to copy to or from any external hard drives. The computer boots up OK, and I can see the data on the drive, however.
Here's what I've done so far: I rebooted the cable modem and the TimeCapsule/Airport Extreme. (I also have a MacBook Pro and verified the internet connection working fine, so I figured it was something wrong with the G5.) I then zapped the PRAM, ran Disk Utility for permissions repair, then ran TechTools for directory repair, then ran Disk Warrior for directory and file repair. I tried to connect to the internet and copy files after each attempt, but to no avail. Anyone have a suggestion of what it might be and how I can fix it? I did have a recent backup on the TimeCapsule, but I'm unable to access is because of this internet connection issue.

Was the power failure a dropout or could it have been a spike and then an outage. If you have no UPS and no surge protection (not that it helps much) then you may have some damaged hardware.
Since you can boot, check the console logs and also the System Profiler to see what, if anything, is wrong.
Normally the Leopard journaling filesystem takes care of these types of outages, which is why I suspect more than just a simple loss of power, but rather a surge.
And when you do get it working again, which I am sure you will, since you do have a TM backup, I would most strongly suggest getting a UPS for the computer. I even have my notebooks running through UPSs.

E4500 firmware corrupt after power outage

Latest firmware with CCC corrupted after power outage. I reseet the e4500 several times and tried to reload the firmware and still no good. Only way I got it back up is to install the older non-CCC version 2.37. Strange all was fine until the power outage. Not sure if I should even bother to upgrade to 2.38 again.

Yes, power outages may caused some damage either on the hardware or software of the any device especially if there's some activity going on inside the device the time of the interruption. If everything is fine with the old version then there's really no need to update it but if you've noticed some issues, better upgrade to the newer version so to fix any problems.

My AppleTV stopped working after power outage. Light is on and I rebooted and reset w remote but it keeps giving me a pic of the Hdmi cord like it is not recognizing the hdmi as being plugged in. I've unplugged it several times.

It is in recovery mode. The picture is telling you to connect to iTunes via micro usb cable in order to restore.

Hyper-V - virtual machines don't start automatically after power outage

Hi,
I have a HP server running Windows 2012 R2 + Hyper-V. On this server, four VM have Windows Server 2003 R2, and one VM has Windows 2012. After power outage, 1 2003 R2 VM and 1 2012 VM are started properly, but the other three machines aren't. I've started
it manually. All VM's have last version of Hyper-V integration tools installed, the option "Automatically start VM if it was running before the service was stopped" was chosen. I'm not very familiar with Hyper-V, so, I've investigated only Hyper-V-VMMS
event log. There are some recurring errors:
The Integration Services Setup Disk image could not be updated: The process cannot access the file because it is being used by another process. (0x80070020).
and
Failed to get the disk information.
But I think it isn't a clue.
How can I clarify, why these machines aren't started automatically?

Hi EugenBerend,
Maybe it is related to system resources allocation during the start up .
I would suggest you to configure a startup delay for those lower priority machines so that system
can locate enough resource for them.
Hope it helps

Lion server : local user account disappear after power outage

On the server computer.After power outage I restart server the machine starts up ok.At login screen local user name disappear but there's others account same as client computer.I can log in to network account but can't log in as local.
In sytem preference local user account is still there.
I don't want to reinstall lion server .
What can i do now?
Thank you for your assistance.

It sounds like the user directory is damaged. You might try booting into the recovery partition, running Disk Utility, and doing a Repair Volume (and maybe a repair permissions) on the server volume.

Lost my pictures in iPhoto '08 after power outage

Hey-
Last night i was organizing some events, it was late and i put the computer to sleep with iPhoto still open, around 3 am there was a power outage. This morning, when I turned on the computer and opened iPhoto, it was totally empty. Does anyone know how to get my pictures back? Thanks!
Adriana

Welcome to the Apple Discussions. To protect yourself from a similar problem in the future see the tip at the end of my signature below:
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: The new rebuild option in iPhoto 09 (v. 8.0.2), Rebuild the iPhoto Library Database from automatic backup" makes this tip obsolete.

Exadata startup after power outage

Hi,
Recently we had a power cycle on one of our Exadata machines resulting in a partly running server.
After checking with:
dcli -l root -g all_group 'ipmitool sunoem cli "show /SP/policy" | grep abled'it seems some components do an autoboot and some don't.
When I checked another Exadata it showed the configuration was for a total autoboot.
Do you have any view what would be preferrable a manual startup or an autoboot?
Or maybe assess this setting for each Exadata individually?
Regards,
Tycho

Hi andy.colvin,
Can you give some more information on what didn't start up?The 4 db nodes didn't boot up on this half rack Exadata but the 7 cells did.
Support pointed me to 1470536.1 about the issue.
It could be in firmware (Active image version: 11.2.3.1.0.120304) or ACS changed the standards for the policy in the ILOM.
I have a second half rack (Active image version: 11.2.2.4.2.111221) which is configured to do a full autoboot (eg HOST_LAST_POWER_STATE = enabled) after a power outage. For now I have changed the ILOM setting to enabled and I will wait for a final answer from support.
Regards,
Tycho

IMac won't boot after power outage

I got a power outage a couple of hours ago. And now my iMac won't boot. When I power it up, it gets pass the white screen with the apple logo. The screen than turns blue with a spinning cursor. The cursor spins for about 10-15 minutes and stops but the normal login screen never appear and it won't boot into the desktop either. I just got a blue screen.
I have boot into the install Disc1 and did the disk repair and premission repair but it didn't help.
Any idea?
Sidney

Oh man, what a disaster!
I tried to do an Archive and Install but the installation hanged at the end of disc 2 after running an iWeb script (according to the install log) with about one minute left. I have waited for two hours but it just hanged there with all the drives spin down.
To make the problem worse. There was no way to quit the install at that point because all the menu items were disabled. The only way out was to power off. But when I powered it back on, it booted right into install directly asking for the disc 2. If I put the disc in it will install again and hang at the same spot.
Disc 2 contains iLife. I know Apple wanted to make things simple but why can't they give me an option to skip it? After all, iLife was already installed.
I finally got it working by booting from disc 1 and did a clean install. It took me all night to re-download all the updates and reinstall many applications. Fortunately, I have my address book, calendar, and most of my works backed up to .Mac so it wasn't a total lost.
On the bright side. Now my iMac is working better than before. I used to have problem getting auto sleep to work but now it works perfectly. Safari also had problem accessing charts (but Camino was fine) in a few web sites like schwab.com. Now everything works.
Lenn and David. Thanks for all your helps.
Now I am looking for a better backup solution so that the recovery won't be this painful if disaster strikes again. Any suggestions?

Cannot login to my usual account after power outage

Had two power outages last night; machine survived the first one, but after the second outage and restoration I cannot get in to my usual user account. What happens:
Grey apple screen, normal
Blue screen with progress bar indicating that OS X is loading... before the indicator fills all the way to the right, it exits to a blue screen [of death] with a mouse cursor (which works) and just stays there. It goes no further. Rebooting obviously does not fix it; I rebooted a dozen times trying to get beyond that.
What I've tried that hasn't fixed it:
Rebooting
Unplugging and replugging, both computer side and wall
Repairing both the disk and permissions--done, no effect
Safe booting and attempting to log into the account under a safe boot--it loads the wallpaper and hangs right there, no dock, no menu loaded
Removing the User/~ Preferences folder
I believe that what is causing the problem is some login startup item. However, since I cannot even log in in Safe mode, I can't start the System Preferences Accounts panel to remove login items.
Question: Is there another way to remove the login startup items? Removing the Preferences folder has not helped. I'm missing something. What is it?
I can log in to any other user account. I am currently in Root.

From the root account, open the Accounts pane of System Preferences and delete the login items for your normal account; an admin account should be able to do this for any account on the system, while non-admin accounts can only be used to change their own login items.
If removing the login items does not fix the issue, remove other parts of the home folder until you are able to log in to that account. If you've removed/renamed the entire home folder and aren't able to log in successfully, check that the permissions on the hard disk allow all accounts to read it; if you still can't successfully log in to that account, restore a previous version of the NetInfo database.

Unable to load OS bound to a domain after power-outage

I currently manage 200 2013 iMac but since installing Yosemite I've noticed that after the macs are joined to the domain and a network user is using the machine and a power outage occurs ALL iMac running Yosemite will not boot up. The boot process reaches about 30 percent and stays on the grey apple logo screen. After extensive troubleshooting we found that this only occurs when a user is logged in when the power outage occurs. However if the power outage occurs and the units are not being used by a network user the computer boots up fine. We completed a fresh install created a local user without adding it to the domain. We then logged in with the local user mimic'd a power-outage and the computer booted up fine. I have done extensive troubleshooting noticed that the issue does not occur with local users only users authenticated on a domain.
Note: We also noticed that if we deleted network users from the user folder and then performed the power outage and the unit loads the OS fine.
Any help with this is greatly appreciated...

Insert the Mac OS X 10.4 installation disk into the drive, and then restart the computer with the Option key held down. If you are able to successfully start up from the drive, install Mac OS X 10.4.

865PE Neo2-PFISR problems after power outage

I need some help with a problem. A recent power outage while my supposedly "surge protected" 865PE Neo2 based machine was running, apparently messed something up. After our power came back on, I powered it back up and discovered that I now have 4 ongoing problems. Problem 1) it now hangs twice during the boot process, once at "auto detect 3rd master - press escape to abort", which if I then press ESC, it then moves to "auto detect 3rd slave - press escape to abort" and hangs there until I press ESC, at which time it then finishes booting like normal. (by the way, I don't even have any 3rd master or 3rd slave installed) Problem 2) I can no longer enter the Bios setup, even though I press the DEL key at the appropriate time. Problem 3) The case light for hard drive activity stays on constantly, even though the drive seems to be working normally without any other problems. Problem 4) A few issues here. My sata dvd/cd combo drive is no longer recognized as being installed; the activity light on the drive is constantly on even though the drive is not running; the drive bay will no longer open.
I'm guessing that something has possibly been damaged on the motherboard or maybe the bios was affected somehow, or maybe the power supply was somehow damaged. Either way, I'm not sure what to do now. With the exception of the problems I listed, my system otherwise works normally as it always has, with the only real downside being that I don't currently have a dvd/cd drive. I haven't tried any troubleshooting myself because I'm not sure where to look or what to look for. The specs for my system are listed in my signature, with the only change being that I'm still running the original Antec 350w power supply that came with the case. I could sure use some expert advice and help with this.

Problem Update.
Well, I finally got my machine up and running "almost" as good as it was before my power surge problems. Thank you to everyone that responded with advice. I ended up replacing the Antec 330w TruePower psu with the new Enermax Noisetaker 420w (EG425P-VE SFMA V2.0) that I had, and I had to replace the MSI sata combo drive (went with a Pioneer 710 DVD-RW, which is an excellent unit) and now things are back to normal. Plus, I bought an APC 650VA/390watt battery backup with soft shutdown to help prevent any power outage problems again.
When I said "almost" as good as new, that is because this morning when I booted up, all I got was a black screen (no post) for a couple of minutes, and then a message appeared that approximately said "the dram timings are too tight, reload timings", or something like that. Well, since the timings have never been changed, I'm not sure what is going on, but after turning it off and then re-powering it up again, it booted (though slowly at first) and I've just been letting it run all day. Ha, just when I was ready to venture into OCing this rig. Think I will anyway. If the problem continues, I'll be back seeking helpful advice again.

Can not start web server after power outage

Hi All,
I have a Cisco NSS322 running firmware v1.0.0. I have Web server with MySQL, file sharing on the box. after a power outage this morning, I could not access the web server anymore. I can access filesharing and web GUI management interface (port 8080). I login to the box via ssh, and do netstat -na, and found that the box does not listen on port 80.
From Web GUI, I tick/untick the "Enable Web Server" number of time but can not turn on the services. The logs say re-lauch apache sucessfully.
Could someone help please?
thanks
Tao Lao

Also you're running on the engineering build of firmware. You might need to upgrade to latest versions.

External hard drive not recognized after power outage

After a power outage last night my WD external hard drive is not showing up. The power light is on on the drive, the DVR is working normally, except my external drive is not showing up. I unplugged power from the DVR and restarted it, but no change.

I have a 2G Samsung drive in Rosewell external encloser running for over a year. Two times have lost power and DVR would not recongize external drive. The procedure I used was to reboot twice via menu>settings>customer support>in home agent>reboot STB. Mine required two resets, the first reboot looks like DVR recongizes drive but does show as available but second reboot shows disc activity during last part boot up of box then external would show with all recordings and normal operation. I have not lost any recordings.

Photoshop fails to run or re-install after power outage

I experienced a power outage while performing an update to Photoshop via Creative Cloud on my iMac. Since then I have been unable to use or re-install the app. Initially when trying to re-install, Adobe Application Manager would run through most of the install process and then error out towards the end, stating that the download was corrupt. This happened twice, and now after several reboots I no longer have the option to un-install on the Adobe sub-menu. Other Adobe apps seem to function without issue.

Run the Creative Suite Cleaner Tool, download AAM from here:
Adobe - Adobe Application Manager : For Macintosh
Reinstall everything.
