Powerbook won't star

recently my powerbook, while awakening from sleep mode made these really odd beeping noises until i clodsed the laptop and then last night after i took it up to my room and plugged it back in before i went to sleep the computer started making this long whining noise until the computer itself shut off and now it will not restart. I have already tried resetting the PMU but it just won't turn on. Has anybody else experienced anything like this or does anyone know what the problem could possibly be and if I can do anything to fix it instead of taking it in? Thanks

Powerbook won't sleep if USB mouse, printer attached: is there fix?

Hi there,
Thanks to someone, I now know that my powerbook won't stay asleep more than a couple seconds, because I have various USB items attached (mouse, printer, Wacom tablet). I've been having to unplug from the USB port, if I want to put my computer to sleep.
This seems a little ridiculous to me, so I figure there must be a third-party app out there that fixes this issue. Is there? Or is there some other way to fix this, without having to unplug?
Thanks,
Malcolm

That sounds like a good idea. I've just tried it and it did nothing but i've found info on the following page that has a different set of keys. It did restart twice as described but the problem is still there:

Thanks for trying though... Any other suggestions?

AC adapter bad? Powerbook won't run without battery

I think my powerbook (G4 aluminum, purchased Dec 2005) AC adapter is bad--the powerbook won't boot up without the battery (which, thankfully has not been recalled!).
I did check the AC issues listed in this Apple doc:
http://docs.info.apple.com/article.html?artnum=302461
The light on the adapter is green, the battery charge indicator menu states "Charged." However, none of the 5 lights on the battery are lit when the AC adapter is plugged into the computer and an outlet.
I have both AppleCare and ProCare--would a replacement AC adapter be covered under either plan?
P.S. the logic board was replaced in this powerbook last week by Apple because the computer would not boot up, there was a loud "fan" sound and one beep every 3 seconds.
Anyway, help!
powerbook G4 ( Dec 2005) - ARRRGHH! Mac OS X (10.4.7) and ibook G3 (10.3.9) -- never any problems!

I appreciate your advice! I agree that I should take in the powerbook for another round of repairs. However, I want to get some idea of the possible causes of this problem before returning it. Here's why:
[warning: venting ahead]
I am not taking it back to the nearest Genius Bar because of the poor, indifferent service there. Specifically: first guy guesses that the logic board needs replacement, and says the contents of my hard drive are not "protected," then tries to sell me ProCare, which has some kind of hard drive back up deal included. Since I hadn't backed up in months, I bought the Procare contract.
The next day, a different local Genius tells me that the hard drive could not be recovered, it was the cause of the computer crash, and just the hard drive will be replaced at the factory, and it will take 2 weeks.
Two days later, another Genius calls to say my computer's ready for pick up. They replaced the logic board, and the hard drive is fine--untouched. Hurrah.
I used my Procare status to get a Genius appointment to pick up the computer. Yet another Genius doesn't want to listen to my complaints about the "hard drive disaster Genius." I make him turn on the computer [battery power] to make sure the hard drive is OK (yes). I am then shooed out the door.
This is why I don't trust the local Geniuses to examine my computer again. The second nearest Apple store is 25 miles away, so I guess I'll go there for future repairs.

Powerbook won't run off of battery - requires PMU reset to power up with AC

Like everyone else posting here, my powerbook won't run from the battery. I have two batteries, one that came with the computer 3 - 4 years ago and a newer one that I purchased about 1 year ago. When I am plugged into AC using iStat Nano the newer battery shows cycles 173, health 89%. The older battery show cycles 0 and health 100% (go figure!). Both batteries just say 'calculating' on the tool bar battery meter. The light around the AC adapter plug always shows green as if the batteries are fully charged.
Here is where my post differs from the others. Once I shut down the computer I can't power it up again with reseting the PMU. I've tried reseting NVRAM and deleting and re-establishing the powermanagement plist as suggested elsewhere on this forum to no avail.
Is the PMU something that can be replaced? How is it related to DC-IN? I've read elsewhere here that is another problem that could cause these symptoms. Has anyone had these two components repaired and did it fix the problem? How much did it cost?
Thanks in advance for any information you can give men.

I had the same experience. I have 10.4.10 on the cloned drive but the battery is still not charging. I decided to take a closer look at the battery updater instructions and discovered that even though I am at 10.4.11 on my Powerbook the BatteryUpdater.bundle was at revision 1.1.3 and hadn't been updated since Jan 6, 2006. So I downloaded the BatteryUpdate that is posted at the top of this forum and installed it. It has made no difference in the operation of the computer. The AC adapter still isn't charging the battery although the green ring light is on which usually indicates the battery is charged. furthermore, when I go back and look at the date and version number on the BatteryUpdater.bundle they haven't changed. Who knows what the update actually changed! There is no mention of it running in the software update log. My system profiler says:
The battery is installed
Full charge Capacity 3890
Remaining Capacity 0
Cycle Count 173
AC adapter cannot charge battery: YES
By the way, my battery is a replacement battery.
I have just about exhausted all my option other than taking it into an Apple repair store and I'm not sure at this point I want to give Apple any more of my money. I am going to live with it the way it is for a while in the hopes that someone will post a fix for the problem. Good luck with your investigation. If you find out anything else please post it here as I will check back on a regular basis. If I find out anything else I will do the same. Nice working with you.

PowerBook Won't Boot Past the Apple and Spinning Flower Screen...

I've been reading a lot of these forums, but still haven't figured out how to fix it on my laptop. So, I made my own topic.
Anyways. My dad gave me this laptop since he got a new one, so it's a hand-me-down which means I don't have this startup disk that I keep seeing talked about. I've tried Safe Boot, but when I do it with Command + V, it says all sorts of things that I just don't understand, and there is a lot of talk about the Apple Power Management? Such as:
com.apple.driver.AppleIntelCPUPowerManagement isn't a valid mach-o (magic is cefaedfe)
error mapping module file com.apple.driver.AppleIntelCPUPowerManagement
can't map com.apple.driver.AppleIntelCPUPowerManagement in preparation for loading
couldn't alloc class "AppleIntelCPUPowerManagement"
Etc, etc. And then the last lines that it ends with say:
BSD root: disk0s3, major 14, minor 2
[HCIController][configurePM] power parent ready after 1 tries
And it just stays there and doesn't boot up.
I honestly don't know what any of this means, or if it is even relevant to why my PowerBook won't boot past the Apple screen. If you have any information on how I could fix it, that'd be great. Also, if you have any questions that would help you figure it out, ask away and I will answer them.
Thanks a lot.

MixtapeChick:
Welcome to Apple Discussions. Congratulations on your "new" PowerBook. I suggest that you begin with this combination procedure:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
Let us know how it goes.

Powerbook won't start up past grey screen

PB G4 17inch
10.4
Did a software update and now powerbook won't restart.
Stops at grey screen with Apple on it (no spinning icon underneath)
Here's what I've tried :
Inserted Tiger upgrade DVD
Started up holding down option
Both DVD and Hard Drive show up - I selected DVD and finished starting up
I ran Disk Utility / Repair Disk
At first it found a problem with a Cache count (didn't get the exact message)
It continued and fixed the problem
I repaired permissions
Tried restarting - stopped at same point
I ran the installer and reinstalled the OS
Still wouldn't start and stopped at same point
I have repeated the Disk Utility process several times - it obviously sees the hard drive, but won't start up from it...
Any ideas ?

I would not trash anything. Instead I would backup everything you can see to another hard disk. Once you have done that, let us know, and we can proceed with better troubleshooting methods. Some methods may be risky with data, but if successful then you won't have to recover anything.
It is important to always remember to backup your data:

Powerbook won't connect to the internet via Ethernet?

Hi
Just recently, my 1.5 GHz powerbook won't connect to the internet with an ethernet cable. It connects fine at home when it's connecting through the airport, but then I try to use it with the ethernet cable it tells me that "Ehternet may not be able to connect because it has a self assigned IP address" But I didn't assign it an address, OS X configured it. Thanks in advance for any help.

And your settings in:
System Preferences/Network/Show: built-in Ethernet/
(Tab): TCP/IP; configure IPv4 is set to "DHCP"?

My powerbook won't start up

my powerbook won't start up propperly. instead i can heer 5 beeps and the power indicator flashes. screen stays black. nothing! i tried to connect to an other mac with firewire but my powerbook doesn't respond. i also tried to use the startup disc but again...nothing. what next?
does anyone have an answer to this disaster?
powerbook g4 15' Mac OS X (10.3.9)

Welcome to the Apple discussions.
Sorry to hear about your startup problems. 5 beeps is bad...per this Apple note, it says the processor is unavailable: http://docs.info.apple.com/article.html?artnum=58442

Powerbook won't boot from hard drive or restore disk

I've looked through some of the older posts here and none of them exactly matches my problem, and I've tried just about any possible solution I can think of.
I recently noticed that my PowerBook was acting a bit strange. It was making more fan noises than usual, and sometimes the computer would make the very last noise it makes as it shuts down (which is the hard drive coming to rest, I suppose?), though the computer would still be running. Then, yesterday the computer froze and I hit command-control-power, and when the computer restarted it gave me a folder icon blinking between a question mark and the Mac logo.
I tried restarting again, but I had no luck. Now when I try to start up I get the start-up chime, then I get one of three things:
1) If I restart it without a CD in the drive, I get the blinking folder.
2) If I restart it with the Software Restore and Install DVD in (but without holding down the C key), it gets to the Apple logo and shows the spinning pinwheel or whatever you want to call it, then freezes and some nasty horizontal bars pop across the screen.
3) If I restart it with the Restore & Install DVD in and I hold down the C key, it gives me the Apple logo, then the "Your computer has encountered a problem and needs to be restarted" box pops up.
I tried zapping the PRAM--no luck. I tried Open Firmware; the screen pops up, then I type in "mac-boot" and I get the same thing as in #2 above.
I used the Hardware Test CD; it told me that there was a Mass Storage error with the error code 2STF/1/4. That doesn't sound too pleasant.
I'm not sure what caused it; perhaps it was a heat thing, but I moved it too a different surface. All the hardware is original except for the Airport card, which has worked fine since Christmas. The only recent software changes I've made were updating to the newest versions of iTunes and Firefox. It doesn't seem like a hard drive problem, since the boot CD won't work.
Am I doomed to sending Apple a couple hundred bucks to fix this? The laptop is right at three years old, so even if I'd had AppleCare it would be expiring right about now. Or is it time to buy one of those MacBooks? Or just buy a couple PC's and use each one till it breaks, then throw it out?
Thanks,
Kevin

I finally got to another Mac. I installed Mac OS X onto my Firewire drive, then hooked up the drive to my Powerbook and used the Startup Manager. The drive showed up on Startup Manager and I chose to boot from it. When I did, the startup process continued briefly, then froze just like it does when I try to boot from the CD.
I know my Powerbook's hard drive is shot, and to be honest, I'm fine with that--there isn't any critical, essential data on there. I tried starting the Powerbook up in Target Disk mode, but that doesn't work either--I hear the chime, press T, but the screen stays black.
Now my question is: can I rip the hard drive out? Or do I have not only a bad hard drive, but also something else gone wrong? I'm not opposed to buying a new internal hard drive and installing it myself if that will fix the problem; what I don't want to do is spend a few hundred bucks to take it to someone who's only going to tell me that my omputer is now a paperweight.
Also, my Powerbook isn't one of the ones with a recalled battery. The computer can get pretty hot, even when sitting on a desk, but I just figured that was normal.
Thanks,
Kevin

Help! PowerBook Won't Power On and Start Up!!!

Hi All,
I’m hoping someone out there can help! My PowerBook G4 15 Inch (Original model) won’t start at all. When I push the power button, nothing happens. Nothing at all. No lights, no sounds, no fan, nothing. It was working fine when I put it away on a shelf in my closet about a year ago, but when I took it out to look up a document, I found that I couldn’t turn it on. It hasn’t been dropped, knocked, exposed to water, etc. It’s literally just been sitting on a shelf for about a year. Some information which may help:
1. It appears that the battery does not hold a charge anymore, because I left the laptop plugged in overnight and the indicator lights on the battery still do not light at all when the power status button on the battery is pressed. However, I don’t think this should affect startup when the AC adapter is plugged in – the PowerBook should start up regardless of the power status of the battery. (By the way, I know that the AC adapter is good because I tried it on a friend’s PowerBook and it works fine.)
2. I’ve already reset the PMU (several times) by pushing the little button on the rear of the PowerBook with the end of a paper clip. That doesn’t change anything either.
3. I’ve removed the battery and left the laptop plugged in for approximately 15 hours just in case the internal PRAM battery needed a charge after having been stored for so long. No luck there, either.
I can’t understand what could have happened to it just sitting on a shelf! I had another Mac laptop sitting right next to it for the same amount of time, and that one started up just fine. Does anyone have any ideas as to what the problem could be and a potential solution(s)?
Many many thanks in advance to anyone who can help!

Appler5 wrote:
it seems fairly cheap and easy to fix
Yes, which is why I'd tackle that first. My first suggestion would have been to try the power adapter with a meter or on another Mac or check, but you're a step ahead of me on that, so aside from a possible, but highly improbable death while resting on the shelf, the b.u./PRAM batt is the obvious issue.
I do hope that's what this turns out to be
Me too. It'd be worth it for your time and money, whereas other, major, components would likely not be cost effective, given the PB's age.
I'll update with a post when I know more.
Please do, and good luck!

Help! powerbook won't go to sleep...suffering from insomnia

Hey all,
recently i noticed my powerbook has not been going to sleep. i've reset pram,nvram,open firmware, repaired disk permissions, ran cron scripts the whole 9 yards. I checked system logs and i get this:
Description: System events log
Size: 86 bytes

it seems the powerbook does try to go to sleep but Tiger won't allow it, anyone know whats going on?. Any help is appreciated, thanx in advance

Well, if you are sure its a warranty issue they will not charge you once the issue is resolved. But from what you have said it seems to be software related. I am at a loss what to suggest (sorry). The only last thing I'd say to check is the following:
1) Make sure your folder actions are off in the Finder. Control click on desktop and the menu should read "Enable Folder Actions." If it says Disable I'd say try it.
2) Try logging into a new "clean" new user account (after logging out of yours) and see if the machine will sleep then. If it does look at the StartUp items for your user.

Powerbook won't sleep automatically

Hi,
im reposting because no one replied to my initial post, my powerbook recently stop going to sleep on its on unless i do it manually. Every other energy saving settings works normally the display sleeps after a while but not the computer itself. Does anyone know whats going on?
Any help would be appreciated
cheers

Hi El Pres. --
I'm not sure here, but three things come to mind, but first two questions of my own:
• First, when you say the PB won't go to sleep unless you put it to sleep manually, do you mean that it just won't go to sleep when you close the lid, or does it also fail to go to sleep with the lid open after a set amount of time as well?
• Second, just so I'm clear, when you say you put the PB to sleep "manually," you mean you go to the Apple menu, select sleep and click, right?
Now, here are the only things that come to mind, in no particular order:
• First, you might try setting up a test account, separate from the one you normally use, and log in to that account and try putting the 'Book to sleep by means other than manually -- first by inactivity, using energy saver settings, and another time by closing the lid. See if either or both work when logged in to your test account.
• Second, you might try resetting your Power Management Unit. Instructions on how to reset your PMU can be found here: http://docs.info.apple.com/article.html?artnum=14449
• Third, and this is the one I'm least hoping is the case, but it unfortunately may be worth thinking about: if your PB does go to sleep after a set amount of inactivity via as per your Energy Saver settings, but does not go to sleep when closing the lid, you may have a hardware problem related to the lid's latching mechanism. WIth my 'Book, it's only when the lid has firmly latched, will the unit enter sleep mode.
Oh, yes, I forgot to mention: throughout all your tests of the computer's sleep mode, keep an eye on the little "sleep light" on the latch button and make a note of when you see it pulsing as it properly should and when you do not. This information may help you, us, or, if need be, an AASP or Apple tech, better understand what's happening inside your machine.
Post back if any of the above yields further useful info, or if you learn more otherwise.
Good luck.

Powerbook won't even start up after screen illumination probs

Blah! I have a PowerBook that I bought June 05 and of course the warranty is out. It's recently started doing this weird thing where when it's asleep and I wake it up (by opening and closing the cover) it does not illuminate the screen. Before I would turn it off and on (sometimes a couple times) and it would work again. My friend, who is a Mac pro and who has since moved out of state, reverted it to an older version of the OS then manually updated it (so it's running the most recent version of OSX). Tonight, it wouldn't illuminate again so I tried the old trick. Now it won't come up at all. When I press the power button, I know it does power up and if I look hard, I can see the apple in the first start up screen. But the screen does not illuminate. However, now it shuts itself down and goes no further. So while at first I thought it might be a hardware issue, now I'm not sure.
I have also tried to hook it up to an external monitor and all it does is show a light blue screen then shuts down. It also will not start is safe mode.

Using the external monitor, try this...press the power button to start the PowerBook and then close its lid immediately. Be sure you have a USB mouse plugged into the PowerBook and also have the AC adapter attached. See if that doesn't make the external screen useable. Once the PB is fully booted, you can open the lid if you wish (to use the keyboard).
If the above works and PB seems fine, then you likely have a failed inverter board. The inverter board makes high voltage AC from low voltage DC. The high AC voltage is required to drive the flourescent lamps (also called the backlight) that illuminate the PB's LCD display.

Powerbook won't sleep, just shuts down

I asked about this some time ago and nobody ever had any ideas. I was just curious if someone new had ideas.
My 12inch powerbook g4 won't sleep, if I tell it to sleep, or close the lid it just shuts down. I have changed the settings so that sleeping isn't an option and the screen saver comes on and then the screen goes to power save. The computer can stay like this for days/weeks but if the lid closes it shuts off. Any ideas? All the checks I have run haven't found any issues. I replaced the logic board about a year ago and the problem remained. So, it was either not associated with the logic board or both boards have the same issue. Not sure what else would cause this sort of issue.
I am now running 10.5.4.

sorry - should have added that I already reset PRAM, PMU, repaired permissions, ran cron scripts
Powerbook G4 1.67GHz Mac OS X (10.4.8)

Powerbook won't boot

I have a powerbook G4 that's about 18 months old. I installed Tiger on it about 3 months ago, and have been having misc. problems ever since. It "spins" regularly, and can take up to 15 minutes to come out of sleep mode to where it can boot Safari.
Today it asked to do the Automatic Update, and began to spin again. I could operate other programs normally (Firefox, MSN Messenger, etc), so I just continued doing what I was doing. Auto Update hung, and I couldn't quit out of it, so I forced the computer to shut down (holding the power button for 10 seconds).
Now it won't boot.
I get the initial boot noise, and have tried to boot it normally, which brings me to the initial screen with the gray spinner, and safe mode (shift key), which does the same and then shuts off after about 45 seconds.
Help, please! I LOVE my Mac and would like to be able to use it.
Thanks!!

Did you run the correct version of DiskWarroir on that drive?
You would need version 3.0.3 for 10.4.5. Any other version will not work and could cause a kernel panic.
If that is'nt it mI have kernel panic help for you if you need it. I really think you need to run the AHT disk though. Too bad you don't have it. Do you or your friend have Tech Tool Pro version 4.1.1? That utility will test all your hardware also.
Cheers!
