My powermac dual g5 will not boot up and/or wake up from being asleep

My power mac will not boot up. I hit the power button and it mades the first sound but not the boot sound. My keyboard will not light up or turn on. I replaced the pram battery I hought that might help. It didn't. I am not sure hot to open the disc drive w/o the keyboard working. I am not sure what to do next. I did not hear any clicking from the hard drive. I hope my hard hasn't died. I am running os 10.4.9 Thanks!

If you can get an external 3,5" HDD enclosure, I'd take out the disk(s) that are not backed up, and back them up first on another computer. (You actually should have had bootable backups in the first place, but it's never too late to learn, you learn the hard way ;-)
I could be wrong but I still have a strong feeling that it's a PSU problem.
Good news: if your fans still work, the PSU is not blown (yet). I suspect that dust could cause the symptoms you're seeing.
You have access to an air compressor? Preferably one that has a moist filter. (Canned air is way too expensive, but an option if you don't know anybody with a decent air compressor. Pressure of a can is lower too)
I'd first try to blow it out without disassembly. The PSU is on the bottom, so blow through the frontgrid at the bottom.
You won't be able to get all the dust out, but it might work allready.
I recommend you do this outside, and be surprised by the huge dustcloud that comes out, and be glad you didn't do it in your house.
If that didn't work, I would disassemble your G5, take the PSU out, blow it out more thoroughly, by opening the case of the PSU.
You will find links to guides how to do this in the thread I mentioned in my previous post.

Will not boot up and fans run at high speed

will not boot up and fans run at high speed

after much head scratching I ran the hardware test disk from cd. The test showed a memory issue I eliminated the faulty one systematically. So it wasn't a hard drive or software problem in the end it was faulty memory. What was misleading was the computer telling me there was a fault on the hard drive. The machine works fine now. Thanks to people's comments I learned a bit more about the G5 that helped eliminate probable causes

Satellite Pro M10 will not boot again and comes up with the error message

My Toshiba Satellite Pro M10 notebook will not boot again and comes up with the error message "load error" when I push the power button.
The problem arised after installation of "symantec system works" and trying to restart windows XP professional to make the installed program executable.
What can I do to get the notbook restart again?

Hi everyone
If you cannot acces to the boot menu by pressing F8 you can try to recover the the master boot record from Windows Xp professional installation Cd, to do this:
Attention: don't run these commands if you have more than one operating systems running in your laptop.
Boot from Windows Xp installation cd
Choose repair installation from console by pressing "C" key.
A console will open asking you for administrator password, insert the password and press enter.
Run de command: FIXMBR (It will write a new boot record)
Run de command: FIXBOOT (It will write a new boot file)
Restart the laptop and now windows should start without problems.

My Apple Macbook 13.3" Laptop-Black 2008 2.4GHz Intel Core 2 Duo will not boot up and instead I get a grey screen with a folder and a question mark over it. I've tried Option key, and Control S keys and it still will not boop up. Can anyone help?

If you are running Snow Leopard:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
If you are running Lion or later:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it isthree times faster than wireless.

It rained in my window last night, on my power strip. My macbook adaptor (charger) and iphone adaptor were both plugged into the strip. The power strip is dead. Iphone is fine. Macbook will not boot up and charger light doesn't go on.

It rained in my window last night, on my power strip. My macbook adaptor (charger) and iphone adaptor were both plugged into the strip. The power strip is dead. Iphone is fine. Macbook will not boot up and charger light doesn't go on. I borrowed another charger and still no luck. What should I do? (Charger wasn't plugged into Macbook until I dried it off.)

Spill Cleaning
And, don't think that just because it was two teaspoons and not a glassful that there is a difference.
Some liquid has just spilled into your Mac. What should you do?
Do
Immediately shut down the computer and unplug the power cord.
Remove the computer's battery (if you can)
Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
Note what was spilled on your Mac.
Bring the computer into an Apple store or AASP as soon as possible.
Don't
Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
Don't shake the computer (this will only spread the liquid around).
Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).
Do not put in a bag of rice in as much as rice will get into the ports and optical drive and do further damage.

Tried opening a file in library and it states can't open database with library name? It says Relaunch then will not open? and Blocks me completely from Aperture. I have to go to Finder to Rename it? I need this file how do I get it to open?

Aftershotz,
You're going to have to give a bit more information.
What do you mean by "opening a file in library?" There is no function of Aperture to open files -- you can open (switch) libraries.
You'll have to be more specific about error messages, too. Perhaps some screenshots would be useful to diagnose your problem. "Can't open database with library name" is not enough detail about what Aperture is really telling you.

PowerMac G4 Dual Optical - will not boot & no display

PowerMac G4 Dual Optical - Model Number 8570 EMC No 1914 : 1.25GHz DP/256M DDR@ 333/80G/Combo/MDM Operating system OS X 1st or 2nd release
This machine was used daily until February 2007. From then till the last week of September 2009 the machine was in storage and was not powered up
When tried for the first time in over 2 years, the machine powered up and the main switch on the front of the computer came on but no audible chime was heard. The machine will not boot & no display (apart from grey screen visible).
The 3.6 v lithium battery was replaced. PRAM & NVRAM has been reset via the keyboard commands : CommandOption+PR keys. After this, the chimes would work on power up but nothing is visible on screen. Also although the keyboard is functional evidenced by the success of the PRAM reset commands, the num & caps lock lights will not work nor will the CD drive "arrow" eject button. I have also removed the battery, reset the PMU on the logic board, and left the machine for over 30 minutes before powering up again:
Please advise if there is anything else I can try before I take it to a dealer for repair ?
Many thanks
Mike

Try a PMU reset.

Mac Pro will not boot - HD and Machine are fine.

Greetings, and thank you in advance for your wisdom.
I have a 12-core Mac Pro, and she has been running like a dream. Once a month I run Onyx. Yesterday I did the same and upon reboot I got the grey apple screen and the spinning progress wheel that never stops spinning.
1. I repaired the HD via Disk Utility. All is fine.
2. The contents of the start-up drive are accessible - so the drive itself is not physically damaged.
3. I installed a new HD and made a copy of this Start-up disk via the Disk Utility. It will not boot from this drive as well.
4. I installed Snow Leopard (still using this) on the new drive to make sure the computer was happy. It fires up fine.
5. Everything is disconnected from the Mac Pro
So, I have obvious, and idiotically damaged the start-up disk using Onyx (assumption).
My life would be much better knowing I could do something that would enable me to boot from my current start-up and that's where I seek your wisdom.
Another question would be: If the above is not possible, if I install a fresh OS on the new drive, and then begin to replace all of the folders from the old drive (applications, library, etc.) will I be able to access my files as I did before. My issue is that I use this for music production, and there are literally close to 100 plugins that all have been registered. Going back through that process again would be days of labor, as some of these were purchases years ago. Tracking down serials would be a task. I think you understand.
So any advice that might prevent me from having to do as I said above will be wonderful.
Thank you all so much.
Lance

Under some circumstances, you may need to reinstall Mac OS X. You can reinstall Mac OS X while keeping your files and user settings intact.
from:
Mac OS X 10.6: Reinstalling Mac OS X
If your Hardware is functioning correctly, and your disk has no un-repaired Directory problems [Hint: run Disk Utility ( Repair Disk ) first] then re-installing Mac OS X modifies ONLY the files that are part of Mac OS X. Your Added Applications, User files (which contain preferences and serial numbers) are not supposed to be touched.

CRIO startup directory was typed STARTUP and now will not boot. How do I recover from this error or how do I rename the directory when my proxy server is read only due no startup files?

I loaded files on the cRIO but used upper case letters for the startup directory. Now I cannot access the RIO since it didn't boot. The proxy server comes up read-only so I can't reload the files or change the directory. I tried the RS232 port but I can't get it to respond to commands even though I can see the processor boot.

There is NO need to put your entire question into the subject line of your post.

PLAYBOOK WILL NOT BOOT UP AND NO RESOLUTION IN SIGHT

Hi All,
I bought my PB quite recently and now my PB can not boot up and there is NO RESOLUTION in sight. I don't even know whether my problem is software or battery related.
First my PB can not boot up. The last time I used it , the power level was just under 50%. I managed to charge PB to full power (I knew this because LED showed a solid green light). When I tried to start PB, LED showed a red light briefly (for 4 seconds) then everything went off.
I tried all the solutions appeared in this web site:
1/connect to a power charger then press power on/off button for (10,20,30, and more seconds)
2/connect to a laptop and press power on/off button for (10,20,30, and more seconds)
3/start PB by holding down power on/off and + and - buttons at the same time for 10,20,30, and more seconds
4/start PB by holding down power on/off and + and - buttons at the same time for 10,20,30, and more seconds with friends (several friends will help me pressing these buttons in different combinations while other check the clock for 10,20,30, or more seconds). (we were called victims of PlayBook around the office nowadays).
Anyone has other solutions for us ?

Try plugging the PlayBook into your computer, then open the BlackBerry Desktop Software. Your computer will try to connect to your PlayBook and when it is unsuccessful in doing this, it should show a message on the screen saying that the Desktop Software cannot connect to your device and will give you a few options. Select the option to update the device software. This will likely wipe your PlayBook and return it to factory condition, but at least you will have a functioning PlayBook again.
If that still doesn't work, go to http://blackberry.com/support/, select PlayBook, then choose the Contact Us tab. You should now be provided with a phone number you can use to contact RIM in your country.
I hope this info helps!

1GHZ dual G4 will not boot - nada

I have a 1 GHZ dual G4 with absolutely nothing other than the original OS 10.2.1 on the HD & no extra RAM installed and it will not start, not even from;
Original OS 10.2.1 install disk
Apple OS 9.1 install/ restore disk
Apple Hardware Test disk (v 1.2.6)
Single user or Safe mode
Disk Warrior CD (v 3.0.3)
New OS 10.5.1 install disk....
I usually get to the startup screen before either a kernel panic or freeze brings everything to a sudden halt - I've tried every key-combination I have read about but to no avail - any ideas before I reach for the sledge-hammer?

Hi! First make sure the battery is putting out about 3.6 volts because a weak or dead battery can keep one from starting. If it won't start from the hardware disc or the install disc then you have hardware problems. I'd start by making sure the hard drive is spinning up which gives you an indication if the power supply is putting anything out. If the hard drive is spinning I'd unhook it and try the hardware disc and install disc. If it still won't boot I'd unhook the optical drive and hook the hard drive back up and try it. If none of that works then you probably have logic board or power supply problems or both. Tom

Please Help! My Powerbook will not boot up and is SCREAMING at me!

I went to change my laundry and when I returned my mac was emitting a high pitched "scream" from the hardware (not from the speakers). It would not respond to any commands.
I removed the battery and now it will not start up...it will go to a grey screen and make that very loud screaming noise...it sounds like it is coming from a moving part (the hard drive or fan). What should I do?
Thank you all for your time!

hard drive is located in the lower middle of the case, under trackpad, if noise comes from that area could be failed hard drive.

Help! 13" macbook pro will not boot. Tried running disk repair from HD recovery, not repairable. Trying to reinstall OSx Lion, says disc is locked. Do I have to erase the drive and lose everything? I also have Bootcamp installed, will boot to Win OK

Tried running disk repair from HD recovery, not repairable. Trying to reinstall OSx Lion, says disc is locked. Do I have to erase the drive and lose everything? I also have Bootcamp installed, will boot to Windows no problem.

Hotrodmkviii,
try rebooting in Recovery mode, but when you reach the Mac OS X Utilities menu, run Terminal (from Utilities in the menu bar) instead. Inside the Terminal window, give it the following command, and then press the Return key:
diskutil list
Please include in your reply the output from that command.
