Mac wont start, Im just geting a blink light LED light

I was using Illustrator and got a phone call lasting 30 mins, I cam back to my desk and my G5 had gone to sleep and I was unable to wake it up, powered it off an turned it back on and all I get is a blinking light from the LED as if it were still asleep, I tried resting my FMU and changing my battery but I get the same ruslts. Thank You for any info.

Hi iShotz, and a Warm Welcome to the Power Mac G5 Forum!
Does the LED flash in exactly the sleep mode pattern - or in one of the sequences listed at the bottom of the page here

Battery full - Mac wont start. Heeeelp!

I just purchased my MacBook a month ago and I love it. Now Im having a problem...
I just had this problem today. The battery is full but my Mac wont start. But when I connect it to the power adaptor - it will start. Should I change something on the Energy saver option?
I've tried to remove the battery and placed it back, but the problem is still the same. I need your help please... thanks in advance.

Yup, looks like you've joined the Macbook Shutdown/won't boot club. Mine did the same after the random shutdown problem. I reset the PMU and NVRAM and PRAM and suddenly it wouldn't boot or operate on battery. Let me guess, it works fine on the adapter, but when you pull the plug it immediately shuts down, right? Even though the battery is fully charged? I'm also from DK. Did you buy yours at Humac? Mine is being repaired as we speak, well actually it's waiting for parts (new logic board and battery) but it's taking forever. Turned it in on july 25th and it is still waiting for parts. My advice is to demand a new one, don't hand it in for repair, because I seriously don't think they know what is wrong yet. What week is your Mac(Check the serial-number and post it)?
I've heard that a lot of people got the LB replaced, but soon after the problems started again.

My Mac wont start! what can i do?

My Mac wont start! After i restarted it for a update it just crash when i try to start it what can i do?

What and why aren't people doing something simple that has worked for the last 10 yrs:
Clone your system before you ever apply updates
Always have a working bootable backup (or two)
Keep the prior version on the shelf
Keep the combo updates around also.
It is not hard or rocket science.
There is no mechanism to undo rollback or restore check points. No utility to sandbox updates and revert as they sometimes go wrong. Things that are overdue.
MicroMat made having an "eDrive" partition s sinch to do and was its own recovery/emergency boot partition.
Carbon Copy Cloner has been around since 10.2.2, and later SuperDuper and others, Clone X etc.
A clean install is simple. Keeping your emergency boot drive for maintenance updated but with just Apple OS and essential drivers.
Use Safe Boot beforehand. People used AppleJack before updates or at first freeze or sign of trouble.
If you have more than enough room for TimeMachine, then a couple options:
Set aside 35GB is more than enough for emergency boot maintenance (Lion Recovery is nice but doesn't have everything your toolbox might want or need)...
Set up a partition large enough for your working system, again 40-80GB should be enough, you won't clone everything as you can leave your home account folders for TimeMachine if you want (but do want to copy your home Llibrary ~/Library). perfect job for Carbon Copy Cloner.
Setting up an external boot drive is 101 along with TimeMachine.
Not a good idea to have all your eggs in one basket two or more backup drives is better but...
TimeMachine - 350% your total files and changes needed to have file history archived,
Emergency OS
Clone OS
I prefer a 1.5TB minimum.would do fine for most.

My macbook wont start. it just comes to a black screen that sais no bootable device. -asian gal

My macbook wont start. it just comes to a black screen that sais no bootable device.

Ok then either the drive has failed or the cable from the drive to the logic board has failed or the drive is so corrupted that the computer doesn't see the OS on it.
Boot the computer from the original install DVD that came with your system. If your system is new and came with Lion then at startup hold down the Command+r keys and that will either boot you to the built in Recovery HD or to the internet recovery system. From either of those you can check the drive for error and or see if the computer even knows there is a drive in the system.

Hi i am having a big trouble. MY mac wont start past the gray screen. I tried starting on safe boot, single user user mode , recovery mode. Everything it gets stuck on the gray screen i even tried reinstalling it , same thing what should i do?

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

My mac wont start up. please help

hi, i wanted to reinstall osx panter as my computer was running really slow. I put the disc in ad my mac restarted. It now wont start upat all. i've tried holding down shfit and c abd still nothing happns.I can not get the disc out as i have a mac mini and the eject button on the key board isnt working. Do you know what ii can do? When I press the power butten the apple logo comes up as normal but then nothing happens

To eject the CD, depress the mouse button at startup.
To boot from a CD, you depress/hold the "c" key at startup.
Look at these links.

Power Mac wont start up

My power mac G5 wont start up. When i turn it on it comes up with a message saying you need to restart you computer and a load of script drops down in the top left hand corner. I cant get past it and tried everything. This happens everytime i turn it on.
HELP!!!!!

Hi-
Welcome to Discussions!
Have you-
1- Removed/disconnected all devices, except for keyboard, mouse and monitor?
2- Checked your panic log? You can check the kernel panic log any time that you must force restart your computer, using either the power button, interrupt button, or the Control-Command-power key combination. The kernel panic text is added to the log the next time you restart the computer, assuming that you have not reset PRAM at the same time (the kernel panic text is stored in PRAM until you restart). The file is named "panic.log", and it is located on your startup disk at: /Library/Logs/.
The panic report is also the "script" that is displayed when the "restart your computer" message appears. A copy of the report would help.
3- Tried a "safe boot"? Hold down the "shift" key when starting.
http://docs.info.apple.com/article.html?artnum=107393
4- After checking the panic log, try resetting the PRAM:

please help

I fully agree with BDAqua.
Don't do anything with this Mac until you have an external disk which you can boot your Mac from.
Not all USB disks are easy to boot from - FireWire is better
When you have a suitable empty external disk I advise:
Put install DVD into damaged Mac
partitioning external disk into 2 volumes
install OS onto one volume of external disk
Don't import anything during install process - it may reintroduce historic problems
Boot external disk
Use finder to copy critical data from Mac to volume of external disk with OS
Use Carbon Copy Cloner to clone the whole Mac hard disk to the other external volume
Boot into installer DVD and erase Mac's internal disk
Partition internal disk into 2 volumes and install OSs as required

My start up disk is full and my mac wont start

Hi My start up disk is full and my computer wont start how do I get the system to reboot again?

Ensure that the external is correctly formatted
Drag and dropped the files
Test to be sure that the moved files work
Once the moved files work delete the originals

Mac wont start if ADC is not Connected??

I have a G4 Quicksilver Dual processor, with Tiger OSX installed on it. The video card installed has a ADC and VGA connector. I recently wanted to change from the ADC monitor to the VGA(new PC Monitor). But when the apple display is not plugged in the computer wont start.
Why
I have done all the system preference stuff and changing secondary to primary and even swapped video cards with another machine which i know works with the VGA connection.
Please Help
Cheers

I do not believe it's the Graphic Card, I think it would need either a new Logic Board or Power supply.
Which card is it exactly, some can run both monitors at once.
And there may be a slight possibility that a Keyboard like this with a "Power Key" at the top right corner may work to start it...

How can I fix this red blinking SYS LED light?

I am having problems with the extender losing signal and the GPS turns red and the SYS light is slow blinking red. I just spent 40 minutes on the phone with a Verizon tech who had me unplug it and just pretty much said "Sorry, there nothing we can do"!!!! This is happening several times a day for the past 2 weeks.

I am having the same problem with a blinking red sys light and red gps light. The system has been working fine for months and without my changing anything at all, it stopped working yesterday. I am using the correct power supply. I have powered off and on the gateway and the extender several times. My zip is 94306 (although Verizon shows my device as nearby Los Altos 94022 where I think the tower might be). I have AT&T Uverse as my ISP with a standard 2wire modem/router gateway 3800HGV-B. My internet speed is 15.39 Mbps down, 1.93 Mbps up (it is speedtest.net not text): http://www.speedtest.net/my-result/3707324666 VoIP test reports 15.1 and 1.92: Speed test statistics --------------------- Download speed: 15132 kbps Upload speed: 1924 kbps Download consistency of service: 93 % Upload consistency of service: 99 % Download test type: socket Upload test type: socket Maximum TCP delay: 54 ms Average download pause: 1 ms Minimum round trip time to server: 24 ms Average round trip time to server: 24 ms Estimated download bandwidth: 15434 kbps Route concurrency: 1.0199696 Download TCP forced idle: 0 % Maximum route speed: 21845 kbps General information ------------------- IP address: 99.108.141.9 Local time: Aug 22, 2014 4:12:39 PM Test server: http://mcssjc.visualware.com/ Thanks for any help, Larry Kaplan

Mac wont start up

My Macbook pro wont get past the apple start screen. I hear the chime and the apple pops up and it just never stops loading. I've tried turning it off and on, starting it in safe mode, and starting it through the Mac OS X DVD. by putting the dvd in and holding option, I saw that it does recognize my hard drive, and it recognized the dvd as well, but when I try to start either of them, it can't get past the loading screen. How can I get the machine past the loading screen?

Mac OS X: Gray screen appears during startup

Stupid mac wont start

when i press the power button on my macbook i'll get the gray screen with apple in it...
and few seconds later it turns into a weird sign and nothing happens. and it just stays there.
its worth mentioning that i've updated my mac a day before. though i did restart and shut down several times on the day before having that problem.
how to solve it? I need to use the computer.
i'm glad this pc is working
*hugs pc*

I got this sign while booting …
Unfortunately your link gives me an error that I am not allowed to view that page. But I suspect you are talking about the sign shown in this KB article:
Mac OS X: 'Broken Folder' Icon, Prohibitory Sign, or Kernel Panic When Computer Starts Up.
See if anything in that article helps.
i'm really afraid if i do anything I might kill the macbook
A Safe Boot should not do any harm, as you will see from the articles I referenced. But I do not have Windows installed so I can't speak for that. If you're still not sure, perhaps you should try the Macbook forum?
