Power failure during application update, computer will not boot now

Help. I was in the middle of loading a system update when I shut the power off. Now my MacBook Pro does not boot and only has an error message when I power up. I have read some forum topics on downloading a stand alone installer to fix and another on using my leopard install disk\utilities to "restore from time machine".
Has anyone lived through this kind of problem. Any advise would be appreciated.

You mean you forced the computer off with the power button?
When you say the middle of loading a system update, what do you mean? Downloading it, installing it??

You need to boot into the Leopard DVD by inserting the DVD, rebooting and holding down the "C" key. After the language screen, in the menu, top left, under Utilities, run disk utility and repair HD and permissions.
That's the first step.
If that does not work, boot into the safe mode by holding down the shift key on boot. If you get to the login screen, you are probably in good shape - just click restart and let the system reboot normally.

Installed todays security update, computer will not boot, down

I installed todays security update. now my G3 600mhz 14" iBook, running 10.3.9, will not boot.
I have had several symptoms throughout the day. A couple of times it sat there for about an hour with a blank screen. It came up several times with the message to type "mac-boot" ( I may be remembering the syntax wrong) I tried that, I also tried typing "shut-down" at that point.
Later it came up to my background screen bout would do nothing and go no further. Now it is siting there with a OS 9 folder icon in the middle of the screen and sometimes the icon alternates between a face and a question mark in the middle of the icon.

Robert,
I sympathize with your plight. I had a similar problem with my G4 AGP (Sawtooth). Like a dummy, I installed Security Update 2006-004. Upon reading posts about Apple updates on this board, it seem that the knlowledgeable ones wait until the unsuspecting ones walk on the landmines that Apple builds into the upgrades before trying it themselves.
I had exactly the same problems that you describe. Since I believe that my G4 has an extended warrantee, I called Apple Phone Support. The gentleman after listining to my plight, told me that he could not help me because my Mac was a "VINTAGE" model, no longer supported by Apple. How is that for an answer. I guess that now that Apple switched to Intel, all Motorola chips become "persona non-grata".
Anyway, I remember that something like this happened to me some years back with another "upgrade". I believe that basically, the problem is due to the fact that Apple does not make provisions for third party products installed in a Mac. Last time, it was the video card (ATI) that had to be removed in order for the upgrade to work. This time, I had to remove my 2 GHz. Giga Design CPU and put back the measly 400 MHz. Apple CPU. Then I was able to boot normally. I then re-installed the Giga drivers and everything went back to normal. Since I am getting old, and it is recommended for persons of my age to engage in mental exercises, I believe Apple is trying to help me by having my brain work overtime (not to mention the 5 terror-filled hours I spent to resolve the problem.
I suspect the update writes to or resets your PRAM or other non-volatile memory. Does your G3 iBook have any non-Apple components? If so, I suggest you remove it or them. Beyond that, I cannot help you, except to suggest that you reset the PRAM.
I now have transferred most of my data to a fast, trouble-free (relatively) PC. Since in the future, all Macs with have Intel chips, there will be no reason for me, after about 30+ "vintage" years to buy Apple. Of course, just as Apple touts that its OS can run on a PC, PC owners will (are already) running Mac OS on their PC.

Power mac G5 turns on but will not boot up

Hello,
I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
Can anybody tell me what is going on here and is there any way to fix this?
Is there any way to reset or reboot the computer this the install disk?
Distortion on the startup screen (hard to see in this photo)

Hi Mike,
LED 1—CPU A: red—contact Apple or an Apple Authorized Service Provider
LED 2—Overtemp: red—contact Apple or an Apple Authorized Service Provider
LED 3—Power On: red—the main power is on
LED 4—Trickle: yellow—Power Mac G5 is plugged into the wall correctly
LED 5—Open Firmware good: green—no problem
LED 6—CPU B: red—contact Apple or an Apple Authorized Service Provider
LED 7—Checkstop: red—contact Apple or an Apple Authorized Service Provider
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

HT1758 Power failure in the middle of a software update and not the computer will not boot up. The computer just has a white screen with a grey apple and just loads non stop.

My iMac will not boot up after a software update. the screen is all whute will show a grey apple in the middle and will look like it is working but nothing happens; this can go on forever.
Does anyone have any suggestions?

Do you have a backup in the form of a bootable clone or Time Machine? Restore that and then try the update again.
Some things to try here (Safe Boot)

Another option might be to download the standalone from Apple Downloads on another Mac and try installing it in Firewire Target Disk Mode to the Mac that was interrupted during the update.

After installing recent java update, computer will not sleep.

After installing the recent java, daylight savings, and the security update. my computer will not sleep. Does anyone else have this problem? I do have an adaptec usb2 card installed but nothing is plugged into it. Also i don't have any Ipods or external things plugged in. I have had the same setup for the past year with no problems, now it will not sleep. I have also tried repairing the permissions. Please help

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.8 Combo update. Others reading, download the combo update that applies to you!
Cheers!

After installing recent java + security update, computer will not sleep

When you select Sleep from the Apple Menu nothing happens, is that correct? Try this: Go menu > Home > Library > Preferences. Drag the whole of the Preferences folder to the desktop. Restart your mac, don’t worry if things look different, you have not lost anything. Can the mac sleep now? If yes, then its a damaged or corrupted .plist or preference. If you are using Apple Mail, drag the com.apple.mail.plist back to the new preferences folder created on reboot, you dont really need anything else but keep hold of the old preferences (the one you dragged to your desktop) just in case for a month or two. If everything else is OK you can safely delete it. If it has not cured the problem then remove the new preferences folder created on reboot by taking it to the trash, drag back the preferences folder you moved to the desktop and reboot. Now reinstall a clean OS. See how you go from there

COMPUTER DOES NOT BOOT UP ERROR MESSAGE HARD DISK 1

Sounds like the hard drive has failed and will need to be replaced. If you are still in warranty HP will send a replacement. If not a retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance you have a 640GB hdd so you could use a 750GB hdd but not a 500GB hdd.
Your Maintenance & Service Guide shows how to change hard drive:

BIOS update, then will not boot from any drive

This old laptop, 3000 C200 8922 was acting very clunky when on wireless.
Downloaded Bios Version 63ET62WW and flashed it into the bios.
Now, even though I can get to the bios screen, and it shows the hard drive, DVD/CD drive, it will NOT boot from either.
It will also "see" a usb installed, but will not boot from it.
I have removed all power and cleared the CMOS several times and I still have nothing. Tried two different hdd's which have been in the machine and same results.
HELP!! I should have never messed with it......

hi k4pew,
One rule after a BIOS update is to Load optimize deafults after updating.
Try that go inside BIOS Hit F9 to load defaults then F10 to Save and Exit.
If not
Try turning on the computer and start hitting F1 to load the Recovery Menu and see if that will push then Try Reseting the PC.
If still the same Im afraid that the BIOS needs to be reflashed.
Im not aware of any flash tool or a your Previous BIOS Version Firmware available for download.
You can try calling Lenovo Technical Support for any options available for repair.
Im sorry to hear what happened
Regards
Solid Cruver

Computer will not boot when iPod is connected

Hi everyone,
First time Mac user here, so I'm not very experienced when it comes to troubleshooting - there may be a very simple fix for this, but I've searched online and come up with nothing so far.
I've recently bought a 20" Intel-based iMac (Core 2 Duo). I'm using Boot Camp (1.1.2 Beta) to dual boot with Windows. I already owned a 30gb iPod, which has previously been used with a Windows laptop. The iPod has disk mode enabled as I use it for transporting data as well as music and video.
Now that I'm using the iMac as my main comptuer, I keep the iPod docked & connected whenever I'm not out of the house in order to keep it charged & synchronised. However, if the iMac has to restart for any reason (like switching between Mac OS and Windows, or rebooting after a system update), it will not continue booting after making the chime sound. The screen remains white, holding the option key does not display the Boot Camp menu, and no matter how long it's left like this it will not continue to boot either OS. Pressing the Power button causes the computer to immediately switch off. Turning it on again after removing the iPod from the dock results in it booting normally.
Has anyone had any similar experiences?
Thanks

hi xJamez
Welcome to Discussions
Because you said you use the iPod as an external hard drive, I am going to assume that it's not a nano, shuffle, or mini. What I suspect is that the computer is trying to boot from the iPod because the iPod actually has a hard drive in it, and the iMac thinks that it's an external hard drive that it can boot from. In the future, I would disconnect the iPod before each time you shut-down or restart your iMac.
Hope this Helps
Trevor
