IBook Won't Power On

Hi Everyone,
I have a 12" 1.33 GHz iBook G4 (February 2006) that has been faithful to me for the past three years. The battery needs to be replaced (it holds a charge for about 10 minutes or less), but I've been avoiding the expense and have just been using it with the AC adapter.
I was using it last week when the adapter came disconnected from the wall. Usually, this would cause it to switch over to battery power and I have a few minutes to plug it back in before it goes to sleep. Last week, however, the entire computer powered down immediately (I wasn't met with the friendly sleep indicator).
I tested the battery on the iBook and it showed a full charge, but I can't get the thing to start up - not on the battery, and not on the AC adapter with or without the battery removed. Any tips on what I might try short of bringing it in to the Apple store? When I ran into problems with my old iBook G3 they used to try giving it a zap with a higher wattage PowerBook G4 adapter ... maybe that's what it needs :P
Thanks!
Matt

Usually, when a computer goes through a power outage
(and has no battery backup) the unit can be restored if
there was no surge or spike damages by resetting the
Power Management Unit.
When you have a good power adapter and battery, with
all other things being OK, this reset should fix the matter.
Other parts which could go bad include the DC-in board.
Resetting PowerBook and iBook Power Management Unit (PMU)

Did you check to see if the original battery, or subsequent
if OEM replacement for the iBook, was subject to the recall?
Good luck & happy computing!

Ibook won't power-up

I have an ibook G4 that won't power-up, even though it have a full charged battery and it is connected to the mains. (i have tried removing the battery and power cord and holding down the power button for over 5 seconds, and then plugging in again, but no joy).
One other strange thing to note. I've had a trail of Ants attacking my machine, crawling throught the ports, ventilation gaps and generally anywhere they can go... could this have caused some damage?

Upon doing a lot of searching, I have found the following options for replacing a white iBook power adapter:

IBook won't power on, but the fan is running top speed

hy,
just got back an iBook from the Apple Store and now it won't turn on..the screen stays black but the fan (at least it sounds like a fan) keeps running quite fast and loud.....any help would be greatly appreciated
neil

sad thing is the logic board was just replaced (within the last week)...not cool
oh well, thanks anyhow, at least we won't spend time waiting for it to power on

Ibook won't power up after power outage

Help! I had a quick power outage last night and now my ibook g4 won't even turn on. I have nothing from it. The battery lights come on. The charging light from the adapter is on when plugged in. The computer was on a surge protector and all other electronics attached to the same surge protector still work with no problem. There is NO response from the computer at all...not a peep.

Hi doggiesam,
I've had a couple of instances of this kind of thing, though admittedly not related to power outages. Try holding the power button down for several seconds, like 5-10 seconds, waiting a moment and then pressing the power button again in the usual way.
If that doesn't work try a PMU reset:
1. If the computer is on, turn it off. (Again make sure that it is really off my pressing and holding the power button as above)
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the iBook
Let us know how things go.
Good luck,
Adrian

IBook won't power on... power management issues?

Hey everyone,
_MY SYSTEM_
I've got a 12" iBook G4 (1.33 GHz) running 10.4.10 that's about a year and a half old. It's been a great computer for me, and I've used it on an almost daily basis since I first got it. Its experienced a few power-related quirks within the last month or so, however. I can't think of any event that would've caused them.
_THE SYMPTOMS_
I first started noticing that OS X sometimes displayed the low battery warning at odd times or not at all. I didn't think much of it... figured it could be my power adapter coming unplugged or something. Then I started noticing decreased battery life, but I chalked it up to the effect of fairly heavy use and lots of charge cycles. I continued to feel like my power adapter was getting progressively more finicky... it started requiring much closer contact with my iBook than it used to, but since it's a friction fit, I figured the contact was just getting looser.
_CURRENT STATUS_
When I turned the computer on this morning and plugged in the charger the status bar icon didn't seem to recognize it as attached to the adapter. The colored ring around the connection point would go green when connected, but never turn amber. So I used it today until it went to sleep on me. Tried plugging the adapter in, but the same issue existed... the ring would turn green but never amber and the iBook wouldn't actually charge.
TROUBLESHOOTING
I first tried another adapter with no luck. I was able to use the power button to shut my iBook down with the intent to reset the power management unit on startup. That key combo didn't even produce a startup, it just killed the adapter's indicator light for a brief moment. Unfortunately the battery seemed too depleted to start the computer back up. I tried zapping the pram, and that got me to the login screen before the computer recognized it was low on power and went back to sleep.
SUMMARY
As far as I can tell, the computer isn't recognizing either adapter when one is attached. The battery doesn't seem to be the issue. My iBook is completely unresponsive without the battery (only on AC power), and doesn't charge the battery when both are connected. Anyone have suggestions for me before I make the trek to the nearest Apple store?
Thanks,
Matt

If the power adapter seems looser when you plug it in, you might have a problem with your DC In Board. This is what the power adapter plugs into, and it can become damaged.
You can go to http://www.ifixit.com/ and look up the DC In Board for your iBook and see what it might take to fix it yourself. If you go to the Apple Store, have them take a look at it.
Good luck!

Ibook won't power up - was fine before w/ no problems... help!

hello all,
okay, i was using my ibook this morning with no problems. i come home and push the power button to boot up, and it doesn't boot up - it acts like it's dead. doesn't make a single noise like it's trying to do anything - it literally acts like it's dead. i've had literally no problems with this in the entire three and a half years i've owned it (bought it new at the apple store). i'm needless to say a little freaked out right now...
any advice/troubleshooting tips are greatly appreciated!!
thanks!

IBook G3 800mhz powers & starts up, after a shutdown it won't power up

One day my iBook G3 800mhz was working fine. I shut it down and later went to turn it on and it wouldn't do anything... no startup chime, no fans, no lights, nothing. I tried resetting PRAM, PMU, and many other things which didn't work at all.
I had a local computer store check it out and they told me the Motherboard was fried. I pretty much wrote the iBook off as DEAD. I took the battery out and it sat that way for about a month.
Today, I put the battery back in and hit the power button, and IT POWERED UP & BOOTED! I couldn't believe it. I shut it down and hit the power button again... nothing, it was "dead" again. I took the battery out and let it sit that way for about 2 hours, put the battery back in, pushed the power button and it BOOTED JUST FINE. So, I shut it down, pushed the power button and it was "dead." I took the battery out again, let it sit for an hour. This time instead of installing the battery I just connected the power adapter, pressed the power button and it BOOTED. To determine if it was the battery, I left the power adapter plugged in, shut down the iBook and pressed the power button... NOTHING, "dead" again. So, it's not the battery, it's not the power cord.
When I do get it booted, I am able to do a succesful Restart by selecting it in the Finder. Also, whenever it does power up, I am able to reset the PRAM and it will start up. Whenever I do a Shutdown (either from the Finder or by pressing the power button) it won't power up unless I disconnect the battery and power adapter and let it sit for about an hour.
I've been through all the forums and many websites and have yet to find a fix for this problem.
Anyone have any ideas?

Hey Shim..,
Certified Apple Technician and he agreed that it is probably the transistor (what he called it) that is failing, since it's not holding Date & Time
OK but a transistor is a long way from a microprocessor. Uhh where did he get his...oh never mind.
I have read in some forums about the leaking super cap,
I'd be interested in those leads
but I haven't been able to find any photos or anything that shows where on the board this is located.
Just put one up here, it's from a 12" G4 1.2 GHz:
http://www.photolava.com/view/d5pr.html
They're pretty distinctive, so hard to miss.
Here's the blowed up one from the 500MHz 12" G3
http://www.photolava.com/view/d5pu.html
Now that's blowed up
Is this cap replaceable? Anyone know of any step-by-step guide that would show how to go about this, or know of any company that might do this sort of thing? If it's not too terribly expensive, I'd be willing to give it a try.
Well let's determine if it's bad first. Usually when these things fail it's pretty obvious.
I'd try blowing out all the chips we talked about first since I believe a tiny bit of smutz will cause a CMOS micro to crash.
It reminds me of when these early PMUs will crash and drag the battery down with it in a matter of days vs years.
One of the resets in those was to remove all power and let it sit just like you're doing here. This was called resetting the logic board and was SOP for a no startup situation.

IBook G3 700Mhz won't power on at all

Hello,
My iBook G3 700Mhz (CD-ROM, 2002 model) recently died completely - it won't power on, there is no chime, no disk activity whatsoever. There were no indications that there was a fault prior to this - I had used it with no problems just a few hours beforehand. I have heard of logic board failures, but from what I have read some form of activity still occurs, or there are faults that occur sporadically shortly before it completely fails. My iBook has run perfectly since I bought it in 2003 with no sign of any problems at all.
Is this likely to be a logic board fault? Or could it be a fault with the PSU? The battery still holds a charge (it is on 2 lights), the power cable still turns orange when plugged in, so power is still getting to the machine.
I appreciate any help anyone can give - I would like to be able to get to the data on my hard drive, as although I have made regular backups, the last piece of work I was doing (the day my book died) will still be there, and hasn't been backed-up.
Thanks,
Andrew
(iBook spec: G3 700Mhz "P72B", CD-ROM drive, 640Mb RAM, Airport, OSX 10.4.10)

Thank you very much for your help, very much appreciated. Unfortunately, I have no friends with iBooks (just MacBook Pros - very flash), but I have ordered an ibook G4 which, should it eventually arrive (I managed to be sent a job lot of laptop hard disks by accident today, which was akin to rubbing salt in my wounds) I will use to test the power cord.
I think the power problem sounds the most likely candidate, thanks to the article link you sent me. One thing I noticed last night when trying out your tips was that when the power lead was connected, the battery life indicator stayed on the whole time. I'm not sure I remember it doing that before, so that could be an indication of the problem. Also, the ring on the power cord stayed orange throughout, despite the battery showing full power. There are no Apple Stores where I live, but I am hopefully visiting a city with one this Weekend, so I may well take my iBook with me for diagnosis. I'm not sure I can justify the price of a logic board repair, but a PSU replacement might be more palatable.
Again, thanks very much S.U. and Ronda. I will keep you posted on any further developments.

E. o. Wilson iBook won't open after download.

E. o. Wilson iBook won't open after download. It appears to have completely downloaded, but it won't open.

Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Quit iBooks and restart the iPad. Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If neither of these things help, delete the book and download it again. As long as you use the same Apple ID that you bought it with, you will not have to pay for it again.

IBook won't start up all the way...

My iBook G4 has been great. But recently, I've experience a little trouble. Sometimes when it starts up, it seems to only startup part way.
Meaning, that none of my external connections work (iBook won't recognize any of my USB periferals like my printer and external mouse... and unfortunately my wireless internet connection is supported through a USB port, so when this happens, I can't log on to the internet!).
I've also noticed that when this happens, although I get my Mac OSX desktop, I don't see anything on the top-right-hand-side of the menu bar. So I do get my "apple" menu, and Finder, File, Edit, View, Go, Window, and Help on the left-hand-side, but nothing on the right (display control panel, volume indicator, Date/Time).
So, sometimes I start it and it starts up all the way and everything works fine. Other times I start it up, and I can't find my periferals, and I don't have anything on the right-hand sinde of the menu bar.
I have tried troubleshooting on my own by running Disk First Aid (everything checks out okay), and verifying and repairing my permissions. Doesn't help.
Any suggestions? Hopefully I can get some useful advice on this discussion board. If not, I will have to take it in for service.
iBook Power PC G4 933 MHz Mac OS X (10.3.9)

Hi mac824,
It sounds like some system corruption.
Download and reinstall the 10.3.9 Combined update. If that doesn't correct it, an Archive and Install should.

IBook Won't Start Or Charge, Is It Worth It To Fix Or Get New Comp?

I bought my iBook 12" G4 mid 2005 as a HS graduation present for college, I knew that they had problems with the power cables so when the first one that came with the laptop broke I forked over the $80 and got a new one. I had it maybe a month and now the power adaptor IN the laptop won't receive any power from the cable, therefore not charging the battery. I tried the PMU restart thing but that obviously didn't work and I know it isn't the new cable because the light still turns orange, so I was wondering...
How much is it to send it to Apple to have them fix it? And is it even worth it or should I just go buy a new laptop?
iBook G4 Mac OS X (10.4)
iBook G4 Mac OS X (10.4)
iBook G4 Mac OS X (10.4)

Can you get to an Apple Store? Or an authorized repair store? A good place to start would be to see if you can get a free estimate. If your computer is working well otherwise, it's probably worth a little money to fix it. Did you get Applecare? If so, the repair should be free.
Also, if you have a friend with an iBook, try their power cable to be sure that it's the iBook and not the cable--even a new cable could be defective. If you go in to get the iBook checked, carry in the power cable too.
Good luck!

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. What's wrong and how do I fix it? Help!

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. Tried it 10 times with the same result. What's wrong and how do I fix it? Help!

Oh no Mr.Ected!
I can see if we can get your phone back on! I understand how important it is to have a phone. Have you tried this to see if we can get it back on? http://vz.to/1DZhteH . If it is still goes to a red Verizon screen and then to black we might need to do a master reset. While the phone is off try this:http://vz.to/1DZhXkU Be mindful this is the last resort because it will erase everything on the phone. If you have done back up assistant in the past you will be able to get you contacts back. Please let me know if you need any more help.

Please Help! My iPhone 4 won't power on!

iPhone 4, out of warranty coverage, won't power on.
    1.    It has about 60% battery before it dead, but suddenly it became black screen and not responsive (like powered off).
    2.    Whatever I did, like "holding the power button and home button together for 10-25 sec and then pressing the power button again" etc. it just won't power on, no Apple logo!
    3.    But I can seen the "emergancy call" screen when I plugged it with my laptop and it just told me "No Service" at the upper left corner (status bar of iPhone 4).
    4.    iTunes can see it, but only when it was in Recovery mode or DFU mode.
    5.    I also tried to restore it to factory settings in iTunes, but it always gives me an error with various error codes, like 2001, 2006, etc. I also tried restore it under Windows or Mac, but was out of luck too!
    6.    Finally I bought a iPhone 4 battery replacement and replaced the old one with the new one, but nothing changed as if it wasn't replaced its original battery.
    7.    It keeps rebooting at every 10 min or so when It was plugged into my laptop without any operations (pressing any buttons).
    8.    It can be "powered on" only when it was plugged into a computer. It will IMMEDIATELY be in "dead mode" as long as I disconnect it from the computer (like taking out a battery from an iPhone that is powered on)!
    9.    Everything worked fine before it dead, I don't know what happened to it! I am so frustrated!
Please help! Thank you so much!

USB Problem, possibly bad Cable.
I misread your original post "It keeps rebooting at every 10 min or so when It was plugged into my laptop".
I thought you had a boot loop problem, but you say "rebooting when plugged into laptop" this is not the typical boot loop problem, because you had the iPhone connected to laptop.
Connected by what, obvioulsy a USB Cable, Error 2006, is most often due to faulty USB Cable.
Clean that Dock Port Very Well especially with Isopropyll Alcohol, get a good USB Cable, try a different USB port on computer, or try a different computer.

My kid just got an iPod 5th gen (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line and lightning symbol. No other response at all.

Sorry about the long title.....its my first post.
My kid just got a brand new iPod 5th generation (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line on left and lightning symbol below. There is no other response at all no matter what I do, including holding both buttons down for extended period. My other kid got one and it works perfectly.....I have interchanged usb cables ports etc. but still no response....I would really appreciate any help.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Make an appointment at the Genius Bar of an Apple store since you have a hardware problem with the iPod. This is because as you said the same cable works with another iPod.
