IBook G4 won't start after shutting down by itself

My iBook shut down on it's own and won't restart. The power cable is blinking amber and green. I tried restarting the PRAM, but that didn't work. It has happened once before, and I think I remember connecting it to the desktop somehow? I couldn't find info on that anywhere though. Any ideas?

Rayray -
I just had this exact problem with my ibook g4. It just shut off, while plugged in and then wouldn't restart. I finally took the battery out and put it back in and it restarted then. But it doesn't make sense to me why that worked. My battery needs to be replaced (it doesn't hold a charge well now at all), but it doesn't make sense why it would shut off while plugged in...
Hope this helps your problem...

Mac won't start up; shuts down after grey apple start up screen :(

Well I have just recently came off a two week holiday from Mexico, and straight away I log onto my iMac, as usuall I try to update it as often as I can so I am upto date.
Well I did that, and I found that I had loads to update because I had been away. Soo as normall I allowed it to update. I left my iMac to its own devices for about 2 and 1/2 hours, so it can update, whilst I was on the PS3. Once I had finished on the PS3 I had came to find, that when the iMac automatically starts up to install/update software, that it had frozen.
So I left it for another hour, to see if it could sort itself out, but just my luck nothing happened.
So I held down the power button, until I forced shut down my iMac. When I came to start my iMac back up again, it chimed like usual, and went onto the grey startup screen like usuall, then it took ages to respond, the wheel thingy, just kept spinning and eventually it stop and my iMac shut down.
And it keeps on shutting down like that and won't boot up, but some how it has gone into Safe Boot Mode.
What shall I do, a go from here on, to get my iMac back to normal?
Many thanks to any posts in advance.

Think I have sorted it guys with a bit of searching:

K7N2GM-V won't POST after shut down

Hi all.
I just did my first build on a K7N2GM-V and it won't POST after I shut down. When I hit the power button, PSU does not turn on, fans do not turn on, nothing happens. If I wait about 10-15 minutes, then it will POST and boot normally to my XP Pro SP1. Nobody seems to have had this problem and I am stumped.
Could it be due to my power supply? My PSU is the one that came with the X-QPack, which claims +3.3V(18A), +5V(22A), +12V(20A), -5V(0.3A), -12V(0.8A), +5VSB(2.0A). I don't have a spare PSU to test this with.
Any ideas? Please let me know what additional information might be needed.
Thanks.

Laptop wont start after shut down.

Hello, i got problem with HP Pavilion g6.
Yesterday i watched youtube, and laptop was on side, when i got too tired, then i shut down and left it on side for the night.In the morning i got home and thinked that battery is too low to start but when i plugged in power cable then the light even didnt turn on that's next to plug in hole. I have checked my power cable,it works fine but laptop dont do a single thing, even not the single light wont work.
Sorry for bad English,and its hard to write with phone.
Thank you.

Hello Uku,
Welcome back to the HP Forums!
I understand your HP Pavilion G6 notebook does not turn on. If the light around the power connector on the notebook does not light up, either the connector is not functioning or is not getting power from the adapter. If the LED indicator on the adapter is lit, it's a good sign that the adapter is functional, but is not a 100% fool-proof way to determine if it is working.
If possible, try another power adapter. Any adapter that fits will work for testing purposes. Once you have determined if the adapter works or not, discontinue use immediately and replace the original adapter if an alternate adapter works. You can order parts here: HP Part Surfer. You will need the exact model or product number to use this website. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
You may also want to try reconnecting the power connector inside the notebook. For steps on removing and re-seating the power connector you can check out our Maintenance and Service Guide. The steps you're looking for can be found on page 63. Simply remove and reconnect the power connector and see if that resolves the issue.
If the above suggestions do not resolve the issue, I recommend you contact phone support for available service options. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.

This procedure appears to solve the issue.
It MUST be done Exactly by the Steps.
1. DISABLE the Microsoft Antimalware Service
2. REBOOT the machine
3. DELELETE the EppOobe.etl File
(Reference Path) C:\ProgramData\Microsoft\Microsoft Security Client\Support\EppOobe.etl
4. REBOOT the machine
5. ENABLE the Microsoft Antimalware Service
6. REBOOT the machine
7. Frequently CHECK the Administrative Events Log under Custom Views to ensure the error does not reappear.
NOTE: Just Deleting the EppOobe.etl file and Rebooting will NOT work.

PC won't start once shut down

Hi,
I have HP Slimline s3600t PC bought in 2008 Dec with product # FK479AV#ABA. It is running Win 7 home edition for the past 3-4 years.
This problem has been ongoing for past 6 months gradually worsening. PC works fine once it is ON. If I restart, restarts fine. If I shut it down and then try to start from power button on tower, no response. The monitor is working and I have checked with my laptop on that. There is no response on the monitor when trying to turn the tower back on.
I do not even see the power supply light. Then I wait for about 5 min for the power light (a dim yellow light) to come on. Then I press the power button on the tower multiple times. After some unknown attempts, it will turn on but nothing comes on monitor. During this time, when tower 'seems to be on' but no signal on monitor, I do hear as if the hard drive is spinning and fan working as well. I donot hear any beeps.
Then, I turn it back off again and try the whole thing again. After about 30-35 min into this, after several attempts, the PC finally turns on and then I just do not turn it off for any reason.
Also--FYI--, last time I noticed that the fan next to the heat sink has broken at screws but it works just fine.
I understand that this is a 6 year old computer. Is there a way that I can simply sell it back to HP and buy a new HP desktop?
Or do you think it is worth fixing it?
Thank you
BG

Bixing1, welcome to the forum.
My first thought is a failing power supply unit (PSU). Here is a guide to help you troubleshoot it.
You can also test the memory by removing all of the memory modules and replacing them one at a time and booting. Place the single module in the slot closest to the processor.

IBook G4 won't start after 10.5 install

I just installed 10.5 onto my 1Gz iBook G4. Since the optical drive does not function on the iBook, I used my MBP for the install and mounted the iBook in target mode. I reformatted the iBook HD using a GUID partition table and did the install on the newly formatted drive. When the install was completed, I unmounted the iBook and tried to restart it.
Now, I get a question mark alternating with a folder/smiley face. The drive will not mount/startup. I redid the whole install again, reformatting the drive in the process, and I still get the same thing.
The only thing I can think of is that I can't install onto a G4 from a MBP. Perhaps there is something specific about the install that I need to have the host machine be a PPC. But I didn't think it mattered.
Any other thoughts?

I never suggested the formatting was the issue.
But the point I'm trying to get across in this answer, in case it will help someone else, is that if you are installing to a PPC machine, the boot machine must be a PPC machine (and vice versa for intel). You cannot boot a MBP and install onto an iBook in target mode. The system will expect the disc to be partitioned as GUID, and it won't install unless you do.
The solution for a computer with a broken optical is to use another machine with a working optical, putting that machine into target mode. Then you can boot off the machine with the broken optical, from the DVD drive on the other machine. Now, your boot machine will be PPC (in this case) and you can install on an Apple partitioned drive.
This is probably obvious to many, but it took me awhile to figure out, and maybe it will help someone else.

Fire fox process won't stop after shutting down app.

After logging out of FF it remains running in process and I can't restart.
I need to end proc and then re-launch app.

From what I have been reading from other posts on this forum, the issue may
be caused by the clear history settings.
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Then '''Tools > Options > Privacy'''.
The button next to '''History''', select '''Use Custom Settings'''.
At the bottom of the page, turn on '''Clear History When Firefox Closes.'''
At the far right, press the '''Settings''' button. Turn on ONLY '''Cache''' and
'''Form And Search History''' leaving the others off.
This is not a cure but will make it easier if Firefox locks up.

MBP won't start after failed update

my mbp wont start after shutting down during the latest RAW photo update. the update completely failed and now the computer won't boot anything. i could hear the hard drive try to start over and over but never get anywhere, so i inserted the leopard cd. the computer wont even boot from the disk at this point; all i hear is the optical drive making the same, start-up, squeaking sound again and again until i finally hold power for 5 seconds and shut it off.
i have a mbp from summer 2007.

Press the Power Button and immediately press and hold down the Command and the S keys as the machine starts up. This boots you into Single-user mode and you should see white text appear on the screen.
When you see the # Command prompt, type /sbin/fsck-fy and hit the Return.
Now sit back & let your computer do its thing. This should take approximately 15 minutes or so. Depending on how messed up your computer is. Just be patient.
If and when you see the message File System was modified repeat the steps above again & again until you hopefully see the message no problems were found." When that happens type reboot and hit Return again.
If these steps do not work then boot from your install disc to repair disk. I believe you already tried this.
To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Your random question, only Apple can answer that for you. Ask them and back up before you bring in your computer to the Apple store just in case.

My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )
Here is a link giving further details about this chip solder problem.

Here is an example of a USB cady

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

Satellite E45t won't start for few hours after shut down

I have a brand new Satellite E45t-4100. After shutting down, I am not able to start the laptop for few hours. Upon pressing the power button, say after 15 minutes, power button LED lights up but nothing is displayed on the screen. I have disabled the sleep mode from power settings as I was facing the similar situation when trying to wake up the laptop from sleep. Although, when restart is chosen, laptop restarts without any trouble.
Please help.

Hello,
I have the exact same problem as the OP with an E45t-a4300. Purchased almost a year ago (Oct 30, 2013) from Best Buy. Worked perfectly for about 2 months after purchase and then this problem arose. Started when I'd put the computer to sleep, it wouldn't wake up. The computer would just shut off when I'd go to wake it up. When I'd hit the power button to restart, the fan would briefly spin, power indicator/wifi light turns on, then it shuts down again. I would repeat this cycle- sometimes only a few times, sometimes for almost an hour- before the Toshiba splash screen appeared with the "computer wasn't shut down properly" and the computer would restart and run the standard diagonostics. However, at first on a cold start or start from hibernation it would start fine but after awhile that stopped, too, and any starting attempt was met by the same non-start/shut down cycle.
This went on for about 3 months with me basically rarely shutting down the machine. I searched forums at the time and found nothing regarding this problem. Then one day in mid-March, the start-up problem miraculously disappeard- it fired right up. It started perfectly fine and worked with no problems whatsoever for 6 months, including waking from sleep and hibernation, until about 2 weeks ago. Now the same problem is back- it won't turn on with multiple start attempts and shuts down when you try to wake from sleep or hibernation- showing the "computer wasn't shut down properly" on the splash screen and going through the test process when if finally does start. Also, I'm now unable to enter the BIOS page on start up when pressing F2. I also have disabled rapid start, etc after the problem began.
I've owned quite a few laptops over the years (including Toshiba) and work with computer based systems for a living. I REALLY love this laptop a lot (yes, even with 8.1) but this problem is just disheartening. I truly appreciate any help.
Thanks!!

Ibook G4 - won't start up, spins, and shuts down... disk utility repair...

ibook G4 - won't start up, spins, and shuts down... disk utility repair quits. says "invalid sibling link" "volume check failed" "1 volume could not be repaired because of an error" "the underlying task reported failure on exit"
any ideas about how to start and/or recover data ??
thanks

Hi chesterday, and a warm welcome to the forums!
You must repair the HD, your best bet is DiskWarrior from Alsoft...
http://www.alsoft.com/DiskWarrior/
You'll need the CD though.
Unfortunately, Disk Utility can't fix all that much, and the only other Apple Options are erasing the HD, or installing OSX to a second drive, then using Migration Assistant to move stuff over to the new HD.

Auto Start up after Shutting down

I'm new to the Mac and am not sure of this is a normal issue or if there's a setting that I accidentally triggered. On my MacBook Pro when I shut down, it starts up again after shutting down. I'm not selecting restart and am not sure if I updated software and held off on shutting down so I don't know if its that. Is there a setting I have to adjust or is there some issue I have? Feedback is greatly appreciated.

HL
Try resetting the PRAM. Force the machine to shutdown if it won't shutdown. While the machine is turned off with your leftt hand hold down the option+commands keys. Then turn the machine on and immediately with your right hand hold the P key with your little finger and the R key with your index finger. Wait until you hear the Apple chime twice, release all key and let the machine boot up. Also try starting in the safe mode. Make sure the machine is shutdown then power it on and hold down the shift key until you see the gray Apple screen then release the shift key. let it strat up in safe mode. Then login to your user account and try to shutdown the machine again. See if this helps.

MacBook is starting to shut down after 5 minutes.

My MacBook has just started to shut down after 5-10 minutes. The computer still holds a charge, and the battery Percentage says that it's full, so I dont know what's going on.

If it's under AppleCare take it in immediately.
It is possible that a fan might not be working, and causing it to overheat & shutdown as a safety measure.
The other reason could be RAM.
But that's just my guess.
