Powermac G5 doesn't boot

Hello,
my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:
- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.
- no chime
- the fans turn on normally and the hard drive start a little to make noise once powered up.
- no video on display, the screen is black.
- the keyboard is not recognized anywhere I plug it.
- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor)
I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)
As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.
I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.
I only have a redlight on motherboard if I don t put back the glass panel.
I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...
Any ideas?

PowerMac G5 Doesn't Boot to New Image

I'm attempting to install several PowerMac G5s with the same image. All the PowerMacs are the same vintage, and two of the four seem to work just fine. The other two have the same issue.
I created a model machine that's suitable for cloning: installed and updated all necessary software, configured system settings, and then used Disk utility to copy the model system to a read-only disk image. I then used the Disk Utility application to prepare the system image for deployment by Scanning the Image for Restore.
I then restored the image to hard drives with Disk Utility. I placed in the four HDs in the PowerMacs. Two of the PowerMacs booted without a problem, the other two won't boot to the restored image. I tried holding down Option key when booting, and option to boot to the drive never shows up. Also tried resetting the PRAM, but that didn't work either.
Anyone have an idea about what the problem could be?

I've placed one of the cloned drives that I can't boot into in the second HD bay ("B") on a PowerMac G5, and I can see the drive after I've booted into the OS from the drive in the first HD bay ("A"). Ran Repair Disk and Disk Permissions Repair on the non-bootable drive. Each time it came up just fine. No issues.
When I look at the same drive in Startup Disk within System Preferences the drive is not an option to boot to.
Not sure why I can't boot to it, or pick the drive as the startup disk.
I've tried swapping in three different drives that have the cloned image and all of them fail to boot or show up as an option in Startup Disk.

PowerMac 6100 doesn't boot 7.6

Hello,
My Power Mac 6100/60 AV refuses to run 7.6.1. I installed a brand new system from a CD and everything went fine during the installation, but as soon as I restarted I got this white window and the system frozen with no mouse pointer:
http://dl.dropbox.com/u/5417175/6100-freeze.jpg
Shift-booting works, so I thought it's an extension problem. I disabled everything in the Extensions Manager - still not working. System 7.1.2, 7.5.5 and 8.1 worked fine on that computer. Why 7.6 and 7.6.1 don't work?

Problem solved!
Here's what I did. I booted from an Apple Software Restore CD (the one that has all Mac OS versions prior to 9) and initialized the hard drive (again) using Drive Setup 1.7.3. This time I only made a single partition. Then I updated the disk driver. This is something I don't remember doing before, at least not using Drive Setup 1.7.3. And finally I installed 7.6 and 7.6.1 from that Apple Software Restore CD.
I tried installing from that CD before and it failed, so I can only assume updating the disk driver using Drive Setup 1.7.3 did the trick. The idea came to me after reading this tech note:
http://support.apple.com/kb/DL1249?viewlocale=en_US
Mac OS 7.6 discs have an earlier version of Drive Setup (1.2.2) so it's possible 1.7.3 did something different to the disk.

PowerMac G4 Quicksilver Powers On Doesn't Boot

PowerMac G4 Quicksilver 867Mhz (2001)
Running OS 10.5.8. 1.5Gb RAM.
Ny old machine has been running well. Recently after "shutdown" the machine would hang and I would have to powerdown by pressing the power button.
Did some reading on the topic and it suggested that resetting the PRAM might help. I tried this but have run into a problem.
When I press the powerbutton to turn on the Mac, the Power button lights and the machine turns on, *but then the Powerbutton light goes out*. *Normally it would stay on*. The machine then just sits there and doesn't boot up. Nothing happens, and after a while I power the Mac off using the powerbutton.
I did this again with the PowerMacs door open. The main boards little red light comes on, and the fans are working. However I think the Mac Mouse and the keyboard aren't responding/receiving power.(?). (The little red light under the mac Mouse doesn't come on).
I did further reading and tried pressing the "PMU" button, (just once as advised), to reset the "Power Management Unit".
This didn't improve the situation.
As of this writing the PowerMac will power on, the powerbutton light doesn't stay on, and will not boot up. I've read as many posts as I can without finding anything relevant to resolving the issue.
I've tried booting from various disc's but as I said, I don't think the keyboard is responding.
Any suggestions for what to try next, most welcome.

Hi, Robert -
It may boot successfully that way, although the date and time may be off.
The internal battery provides power to maintain PRAM and clock chip settings when the machine is unplugged; as long as the machine is plugged in to live power, a trickle current is used from that rather than the battery (which is the reason for a small spark appearing whn plugging a machine in).
However, not everything is turned on at the same instant - there is electronic switching circuitry that, once initiated via the on button, sequences the power on to various sections. For some reason the presence of a less-than-adequate battery can affect that sequencing negatively. Sometimes removal of a poor battery will allow normal startup.

Applecare CD Doesn't Boot

I cannot start up my mini using the applecare cd that came with it.
the CD does state (as well as the documentation) to hold the C key down while rebooting.
I can do this successfully with my OSX install disc but not so with the applecare disc. I have a macbook (with applecare) and I tried using that cd also thinking perhaps the mini applecare cd is bad but no dice that one doesn't boot up either.
any suggestions? While I don't need to repair anything now, I'd rather have that functionality working and available so in case I do need it in the future.
Thanks in Advance
Mike
Mini G5 PowerMac MacBook Mac SE

The MacBook AppleCare CD will probably not boot since it must be specifically designed for Intel-based Macs
I know, but since the mini applecare cd wasn't working I was trying to see if the macbook's cd would
try holding the Option key (right after the startup chime) instead and
select the AppleCare volume from Startup Manager.
I'll be trying that next
TechTool Deluxe is on the CD and check whether it is compatible with your version of OS X
I'll double check the version, but the applecare cd came with my mini so I would hope its a compatible version.
I'm also going to see if the macbook will boot up with the cd (its own applecare cd)

K9N Platinum - Doesn't boot with PWR2 connected

Hi,
I've just built a new PC with a K9N Platinum Motherboard (7250 Ver 1.0)
I immediately discovered a problem:
-If I connect to the power supply the PWR2 Molex (the additional power connector on the motherboard, to provide additional power to the video card) the system doesn't boot. Computer's LEDs get on for half a second, then it shuts down.
-If I deconnect the PWR2 connector, computer boots fine.
Bios already flashed to 1.51... no results.
It sounds weird to me. I have an Enermax Noisetaker II 485W PSU, the CPU is an Athlon X2 65W...
Have I got a damaged mainboard?
Thanks for support

Quote from: WillyTP on 15-February-07, 05:36:01
Just tried... nothing. Lights and fans turns on for half a second, then everything dies.
I tried to remove video card too, nothing changes :(
sound like somethink is shorted. try take board of case and retry. it maybe dumb question, but are you connect 4pin cable in a right direction?(i know its can be plugged in one way only, but if you use little more force can be done...)

My mac is slow, crashes if iPhoto is opened, doesn't boot sometimes

Hello.
In the last time, my MacBook Pro is very slow and crashes sometimes if I open iPhoto or some other programs.
Sometimes, there comes a black display with some thin white lines and then I have to restart the computer.
Also, sometimes the mac doesn't boot right (you see only a grey display after the apple symbole).
I already repaired the system with Disk Utility and erased it to install a backup of my system.
Thank you for your help!
Best regards....

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

System doesn't boot kernel26beyond

Since a week or so, my system doesn't boot, unless I press <enter> and the power button a few times during the process.
Once it has booted, everything works fine, but it is highly annoying nevertheless.
it seems to have something to do with loading my hardware.
Boot freezes after these log messages:

I am using mkinitcpio already: /boot/grub/menu.lst:
# (0) Arch Linux
title Arch Linux
root (hd0,2)
kernel /vmlinuz26beyond root=/dev/hda4 ro
initrd /kernel26beyond.img
my /etc/mkinitcpio.conf:
MODULES=""
BINARIES=""
FILES=""
HOOKS="base udev autodetect ide filesystems"
I tried removing scsi and sata, since my root is on an ide disk. But the problem persists.
also recreating an image using mkinitcpio or reinstalling the kernel26beyond package using pacman doesn't help.
Does anyone have any idea what might be wrong and how this problem might be resolved.
It seems like a trivial issue since the systems basically works fine otherwise. However, I can't figure it out by myself, I have tried for a week.
Any help would be greatly appreciated.

I'm not sure if this will help you, but I suddenly was having a lot of trouble booting. My system would just freeze with a blinking cursor. I thought it had something to do with my floppy drive because if I changed the boot priority in my bios to boot from the hard disk 1st, the system would boot but would hang for a very long time in areas, and as long as 5 minutes loading uevents. I suspected this was a udev problem.
I issued a few commands to reset udev, thinking maybe recent updates didn't take effect, which did the trick...
# udevtrigger
# udevcontrol reload_rules
After that, everything is back to normal. I'm still learning about udev and I'm still fuzzy about a lot of the techy stuff.

Tecra S1 doesn't boot and hangs at (boot) splash screen

Tecra S1 Model PT831E-107EQ-GR
Problems started a month ago. It randomly didn't booted. After some power off/on tries it finally booted and worked properly. Because it happened more often I've bought a new hard drive (Toshiba 40 GB). I've had Acronis True Image and planned to make a disk clone to the new drive. The problem is that a notebook now doesn't boot anymore so I cannot boot it from A CD nor hard drive. It stops at "In Touch..." logo with "Press [F12] for the boot device selection menu" text and doesn't react any key. I tried to boot with no CD, no hard drive - the same. I also connected internal HD using ATA-To-USB adapter - the same. Does it mean that's not a disk problem but motherboard or other components? Is it possible to enter BIOS before boot selection screen?
Regards,
Jacek

Problem solved. There was a broken PCB under the CPU socket. I've found that pressing with my finger and holding CPU while booting allowed to startup the system while releasing the finger caused system hanging and its total crash. Our local service tried to repair it but with no success. Finally two days ago we've found a working motherboard (a used one) for about 200 USD and now I'm waiting for installing it in the laptop. Th regular price for a new one (about 400 Euro) is too much, but 200 USD is OK. I do like the laptop because of its ports (LPT, RS232). It's used for programming and controlling some older devices. Newer laptops have no LPTs nor RS232s and it's not easy to find a working USB adapter because the software we're using is even from DOS times and has hard-coded IRQs for those ports.
Anyway, I hope it'll back from the service fresh and new, and of course working ;)
Thank you for your tips.

Jacek

IBook G4 doesn't boot

Hi,
I just bought a broken iBook G4 on eBay thinking I would be able to fix it without replacing the logic board. The iBook doesn't boot properly. When I press the power button, I can hear the SuperDrive start up, then the screen with the gray Apple shows up and the OS starts to load normally. But when that screen goes away and the blue background comes up, it just stops there... no "Loading Mac OS X" window with the progress bar. I figured that this may have been a deviation of the iBook G4 logic board problem where people used clamps to pin down the left side of the iBook and hold the faulty chip to the logic board, allowing the iBook to boot. I gave it a shot, but instead of using clamps I tried putting a small rubber shim on top of the faulty chip inside of the case to see if it would work. The first time I booted it up after I placed the shim, it worked fantastically. No hanging at the loading screen, no sluggish performance.
That was the way it worked for a couple of days. However, the booting problem soon returned. I tried booting from a Tiger reinstall disk to verify/repair the disk/permissions, but the iBook hung at the same blue screen. I didn't have the original install discs that came with the iBook, so I couldn't run a hardware test on it. I also tried booting from a Leopard install disk to no avail. Resetting the PRAM, NVRAM, and PMU did nothing as well. I even went so far as to replace the RAM in the expansion slot with RAM that I knew was working, but the iBook remained broken.
The strangest part of this was that the iBook worked perfectly on another computer when put into TDM. I was able to verify/repair both permissions and the disk from my Power Mac G5. Even though the iBook's screen becomes scrambled with random colors and lines after a few minutes in TDM, it functions just fine on another computer. I was even able to successfully boot my Power Mac and iMac from the iBook in TDM. Seeing as this was possible, I tried reinstalling Tiger on the iBook (in TDM) remotely from my Power Mac. It worked like a charm. Following that reinstall, I downloaded and installed all of the software updates. Then I tried to boot the iBook natively again, but to no avail. It still hung at that same blue screen.
At this point, I suspect that there is something wrong with the logic board that I am unable to fix without completely replacing the logic board itself. That's sort of disappointing, but I guess that's just the way it is. If anyone has any input to this, feel free to respond. Here are the iBook's specs:
CPU: 1Ghz (1064Mhz)
RAM: 256MB soldered, 1 expansion slot open
HDD: 30GB 4200 rpm
Screen Size: 12 inches
Optical Drive: Combo Drive
For the complete list of specs, see this page: http://support.apple.com/specs/iBook/iBookG4_Early2004.html

I just took the heatsink off and I see the GPU. However, there are multiple parts to it.
So that would be called a daughter card. The problem with a daughter card is that the possibility of a reballing/reflowing failure is increased.
Should I place a shim over the whole chip or just one part of it?
It's that whole daughter card that has the problem. I've got a post around here somewhere. Here's the thread:

The picture is here:

Also, what material should I use for a shim here?
Probably the most elegant solution would be to use thermal pads like the ones that are already there. Don't build them up too much.
What about from underneath?
My fear is that a metal shim will short the GPU and damage the logic board permanently. But I also fear that an insulating shim will not conduct heat as it is supposed to and cause the GPU to overheat.
Dale at Superior says that chip doesn't put out much heat but better to be overly cautious. I wouldn't use metal since there's no give to it. What's directly under that 9200 daughter card? One of my thoughts was to shim from both sides.
Where did you put that first shim?

My macbook pro model A1226 doesn't boot up and the screen is black, ived try all reset commands with no luck, or try to go in safe mode, and nothing, please help

Help please, my macbook pro model A 1226 doesn't boot up, i hear the optical drive sound starting but no screen light or booting sound, ive'd tried all redet commands, and safe mode but no luck, can anyone give me an solution to my problem. Tnx

It looks as if there's a problem with your GPU. With a Retina machine, that would mean replacement of just about everything, except, perhaps, the flash storage drive.
Print you kernel panic when you go to your Apple Store appointment. I'm betting that it's a faulty GPU but they will be able to diagnose exactly where the problem lies.
Good luck,
Clinton

Mac doesn't boot after splitting BOOTCAMP drive under Windows 8.1

Macbook pro mid 2012, OS X Mavericks
I've installed Windows 8.1 x64 using Bootcamp assistant. In Windows I went to Disk Management and shrank drive C: from 200 GB to 94 GB and created a new drive D: from unallocated space.
After restart Windows doesn't boot giving some error and quickly restart. If I hold "Option" key I see only Windows. Mac OS X disappeared.
How to fix?

So, I've tried 1001 ways to recover. Nothing worked. Interned Recovery gives -2002F error. Macbook pro 2012 can't boot from bootable DVD to use DiskWarrior, Drive Genius or similar. It can't boot from OS X Lion install DVD. I had only Windows PC to fix this. So
I asked a friend with latest Mavericks(which I had too) to make a Recovery USB and make a DMG file from it and send me over internet. Then I used the TransMac application under Windows and burned DMG on my USB stick. My god it worked. After 2 days of struggle I found this solution. I was able to boot from this USB stick into Recovery Mode and from there I can reinstall Mac Os X Mavericks. Somehow it sees my Ethernet cable and doesn't give error.
Note: that Disk Utility wasn't able to recover partitions. I tried to run DiskWarrior from terminal but it gave me an error. TestDisk didn't run too. So I'm doing a clean installation.
I could recover or backup my files using Paragon Mac Recovery Bootable DVD, but there was no need since it's my new macbook and I didn't have much files there.
Windows had changed the HD partition map from GUID Partition Table(GPD) to MBR. And made HD a "dynamic disk". This is why Mac Os wasn't able to boot.
If anyone knows how to convert a disk back to GPD and make Mac OS able to boot please let me know. I'm still installing Mac Os X on USB stick and didn't change my HD.

HP Stream 7-Windows 10 doesn't boot, I can't recovery 8.1 because can't boot from USB-HELP please!!

Hi everybody, I'm new here!
I am (scuse me: WAS) enjoying a Stream 7
Some days ago I tried to install Windows 10 TP upgrading 8.1 with Bing. After some waiting time it succeeded, but unfortunately I forgave to put in the tablet's SSD the hp drivers, thinking they weren't necessary. So touchscreen, WiFi and all the other stuff didn't work. After I collegated via OTG a keyboard and a mouse I managed to use Windows 10.
Trying to install drivers, my fault, I opened an .exe of Realtek (maybe for the audio), tablet asked to reboot and after that I cannot access to Windows anymore.
I tried to boot Windows 8.1 from a USB, but it doesn't boot, the same even if i disable secure boot.
With disabled bitlocker Windows gives this error
In boot option I set these settings
I put the usb in this way:
The Stream doesn't consider the USB absolutely XD
If I enable again the secure boot Windows gives this error (that at 99% is caused by the .exe I installed):
Rebooting the Stream a couple of time with secure boot it goes in a menu (where touchscreen works) where there are a lot of options to reset Windows, but none of them works. If I try to format from this menu it asks for my account's password, but it doesn't accepts the mine :/
If I try to open the recovery (from volume minus button when it starts) it gives this message:
Waiting for help,
Thank you for your patience!
This question was solved.

Hi everyone. I think I have found a solution to this problem. Short background story, I too tried to install Windows 10 (10049) via Windows Update but I was never successful - got stuck at around 30% for more than an hour. I tried to restore to 8.1 but it gave me that 0xc000000f error. Luckily I had made a recovery image to USB before updating to Windows 10.
Please note that by doing this method, you will obviously lose your data.
Here's what you'll need:
- Recovery USB (if you don't have one, grab it from this link and I thank you that person from another post). Follow the instructions, this is just basically clean, format to FAT32, set primary and active, and then drag and drop the files and folders from the USB folder to the root USB drive. This particular recovery is from a 5701 model, there is actually no difference between Stream 7 models in terms of hardware, but software is configured differently (different language setup/format) depending on the country/region it's sold.
- OTG cable
- Powered USB hub
- USB Mouse and Keyboard
- A moment of your time
1. Plug in the OTG cable to the tablet, and then plug in the USB hub to power and to the OTG. After that, plug in the USB mouse and keyboard and Recovery USB to the USB hub.
2. Boot the tablet to BIOS by holding down Power + Volume Down at the same time, until you reach the Startup Menu.
3. Press F10 and navigate to System Configuration > Boot Options. In this menu, we'll have to restore the settings to default.
So if you have disabled Secure Boot, you first need to Clear All Secure Boot Keys and then Load HP Factory Default Keys. Then enable Secure Boot.
Make sure UEFI Boot Order is also default to as follows: OS boot Manager, USB Diskette, USB CD/DVD, Network Adapter.
If you did not make any changes, proceed to 4.
4. Be prepared to go back to the Startup Menu, because as soon as you press F10 and hit Yes, the tablet will automatically restart. So press and hold the Volume Down button after you hit on Yes.
5. Press F9 and select Boot From EFI File. If you've done the recovery image ghosting correctly onto the Recovery USB, you should see two entries. One should be RECOVERY and the other may depend (it could be SYSTEM or No label). Select RECOVERY, and then select bootmgr.efi.
At this point the tablet will boot off from the USB and will bring you to Windows Recovery.
6. Select your keyboard layout, and navigate to Troubleshoot > Reset your PC.
If the drive partition/boot manager is not damaged, it will ask for a recovery key. You can actually skip this step and hide the numpad, revealing the option Skip this drive if you don't have the recovery key anymore, or just really want to start anew.
If the drive partition/boot manager is damaged, the Reset will proceed and will ask you to select a target operating system. In my case it was Windows 8.1.
7. The next screen will be about Reset your PC telling you what's going to happen. Tap Yes > Yes, repartition the drives > Fully clean the drive > Reset.
The tablet will now do its thing and restore to factory default.
After restoration, a BIOS screen will come up asking if you want to clear the TPM keys. Select Yes, and this will create a new key for the restored installation, bringing you back to a fully factory default tablet.
Notes:
I recommend not installing a generic Windows 8.1 ISO that is copied straight to the USB drive using the Windows 7 USB/DVD Tool or RUFUS. They won't be compressed or the same as WIMBOOT, which will take up more storage space than stock recovery.
You could actually install another version of Windows 8.1 on the tablet, assuming you know what you are doing (ie. making a WIMBOOT image).
You could also actually install Windows Technical Preview directly, again, assuming you know what you are doing.
This is just a guide to help you try recover your tablet from a failed Technical Preview installation. I hold no responsiblities over your actions.
What I recommend is that use 8.1 for now, and wait for the official release (or at least a more stable Technical Preview release for this tablet if you can't wait that long) of Windows 10.

IBook doesn't boot

My iBook (1.2Ghz, late 2004) doesn't boot anymore since yesterday. I treid to reset the battery (by using it until empty, and recharging it) but when my iBook shut dow (when the battery was empty) it didn't boot anymore.
I tried:
-to zap the PRAM (optioncommand+PR)
-to do the hardware test (while holding C)
-to enter open-firmware (optioncommand+OF)
-resettig PMU
neither of these suceeded.
I also don't hear the startup chime.
Is there anything else I can do to try and boot it?
Before this it booted without problems, I don't understand why I can't even get in the open firmware.
alltough my iBook is out of warranty, I suspect this to be a fabrication fault, will I have to pay if I let it repair? (I was planning to buy another MacBook Pro, don't know if I can trust apple products enough to buy them again. This isn't my first problem, I had one of the bad batteries where apple started a exchange program for)

The indicator LED's at the bottom of the battery say it has, and the illuminated ring of the adapter is also lit green.
