Two days ago my iBook G4 (about 18 months old) has started to shut down instead of sleeping when I close it or when I select "Sleep" from the menu.
Strangely enough, it seems to only happen when I have iTunes open before I try to put the computer to sleep.
I hadn't been using sleep mode on my iMac G5 for a while (but it always worked previously to me setting it to "never"), and now yesterday when I turned the sleep mode back on, it has decided it wants to shut down instead of sleep. But it's not a nice shutdown...it just powers itself off, as if it was unplugged. It always boots back up with no problems.
View 1 Replies View RelatedI have an old Dell CRT I'm using currently with my iBook and I want to know how I can just use the display and close the iBook when at my desk without the computer sleeping. Currently if I try waking the computer with the keyboard or mouse, it wakes up for about five seconds before going back to sleep. Is there any way around this or do i just have to keep the iBook Open?

It is an Ibook G4 1.42 Mhz. It will run well when plugged in. Though when on battery it will just shut down ever so often. Like every 30 minutes and then more often after that.
I was thinking low battery or bad battery. But I put in a new battery and then it did it still?????
What ideas do you have for this??
I did a test on the battery and I do know it is pretty bad. But I do also know I tested this book with a new batter and it still abruptly shuts off completely.
When I sign back on the clock has to be reset each time.
Besides that.. Everything is good.
my daughter bought a used ibook g4 15" and it worked for several months before developing a maddening habit of shutting down without warning. I've read other threads about this with ibooks but they say it happens only when the battery is operating and doesn't happen when plugged in. My daughter's does it either way and will only stay on for ten or so minutes most times before shutting down. It makes the machine unusable. We've checked the power supply and the power input board. Is this a logic board issue? She paid $450 for the computer but the prices have come down and it might not be worth fixing. I can solder and can get into the logic board if someone can tell me what to do.
View 2 Replies View RelatedI have an ibook G4 14" 1.42ghz.I have it plugged into a power adapter almost always. It has been plugged in in both instances/I recently put it to sleep and when I return anywhere from 15 minutes to a couple hours it is shut down. I have a heck of a time getting it to power on. It took me several times, anywhere from 3-6 times to get it to turn on.
When I turn it on it goes through the usual loading procedures and after loading a window pops up saying the date and time are wrong and could cause applications to act erratically. The date ends up being 1969 and sometimes the time is wrong.
I have fixed the date and it still happens.
I don't know if this has affected or led to this but my battery has been shot for a couple months now and occasionally (probably 1-2 times a day) the power adapter (a cheap copy of apple's) would become unplugged from the laptop prompting the message stating you are on reserve battery and that the computer will go to sleep soon.
Does anyone know what is causing this? How much would it cost to fix it?
I have done all those PMU resetting stuff. The problem is that my iBook (1GHz, 768MB RAM, Tiger 10.4.3) keeps shutting off when I run it on battery. While plugged in there doesn't seem to be a problem. Here's what I've found out: This seems to happen only when I run the iBook from the battery. There is no pattern as to when it will happen: It might be fully charged, at 70%, 50%, etc. There are no warnings: The iBook just dies
To restart it I have to plug in the charger, I can't start it from the battery after one of these sudden deaths
If I press the battery indicator after a crash, it doesn't show any charge - no green lights
When I restart the machine the battery indicator will work, and it show's a charge in Tiger as well
I've done all that PMU resetting, PRAM resetting, etc. Doesn't work. Any ideas as to what this could be? Bad battery?
One more thing: I've run the hardware test, and it doesn't come up with anything at all.
Coconut Battery shows that my battery should hold a charge as well. Max charge is still at 3500mAh, 18 months and 750 cycles after I got the iBook.
My wife has a three-year old iBook G4 and yesterday while she was doing some work, the screen just went black. By the time she brought it to me the machine was shut down. I hit the power button and it started to boot up, but about five seconds later it shut itself down again.
I kept playing with it and I was able to get back in to OS X and I played with it for a few minutes and all seemed fine. I then shut the screen and put it to sleep, then when I tried to wake it back up it shut itself down once again.
After a few more tries of getting it back in to the OS I was able to get all her files off the hard drive, but the problem is still there.
My guess is that it's the logic board, but that's just a guess.
I recently purchased an iBook used from someone locally. I got a good price because he said the battery was weak. However, I want to make sure that's actually the case. The power cord connection is not loose.
Coconutbattery says my battery is 36% health, but it also says it's not plugged into the charger when it actually is, so I don't know how reliable this program is. It says my mac is 27 months old, i have 367 cycles on the battery... etc. And I am running Tiger.
The problem is that the power meter on the top bar will say i've got a full charge... so I run the computer (on battery) down to about 60% according to the meter, but the computer instantly shuts off. I try to reboot, and it shuts off while rebooting. It's like the battery works fine and suddenly dies. I get about 30-40 minutes use out of the battery.
Is this the battery or do I have other problems? This only happens when using the battery.
I was hoping you could get me started in the right direction. My wife has an iBook G4 which lately, while using a full battery, just turns off suddenly. There is no warning and it never does it when it's plugged in. The battery looks like it's almost fully charged - at least that's what the meter in the menu says, so I don't know what's going on.
Could you possibly give me some steps to go through to try and figure this out?
The first step she wants to try is to get a new Intel MacBook, but I'd like to try a couple of other things first!
My iBook G4 is 3 years old. I have 2 problems: My latest problem is that it won't charge the battery. I bought a new Ac Adaptor, and I used my battery and my adaptor in another G4 and it charges, but not in my computer. So I know the problem is INSIDE my computer. My father replaced the.DC-inboard when the pin off of my old charger broke off inside the computer.
2.) Now the computer won't turn on. If it does turn on it shuts off 20 seconds later.
There is no warranty, I don't know where to start with fixing it since I can't get it to stay on.!
I was given an old ibook G4, with a borken hard drive.
since it would boot from a firewire drive on mac os X 10.4 ppc, I decided to change the hard drive, which i had never doe for a laptop. I had a very similar 40 Gig toshiba IDE drive from an old laptop, opened the ibook and changed the drive.
everything works, the mac boots fine, sound, video etc, yet I realised that it had one rather serious issue. It shuts down when moved / tapped, even very lightly, and this is problematic for a laptop. I was considering buying an airport extreme for it, but now I'm afraid this might not be mendable, nd i'm reconsidering.
what could be wrong ? is there somekind of shock sensor that could have been damaged ? I put back all the screws, and only changed the drive and proceeded cautiously, but maybe something was damaged- what could be causing this, is there a specific area I should focus on ?
My school-computer (iBook 14" 1,42 Ghz G4, running OSX 10.4.10) has developed some unpleasant habbits lately. With lots of batterycharge left, 28-50%, it shuts down without warning. I try to restart it, and it gets to various stages of booting before shutting down again. It won't run untill i plug in the powercable, and then it starts of from almost half full charge. I did a bit of searching on the forums, and installed coconutbattery with the attached (depressing) result. Tried resetting the pmu, which didn't stop it from shutting down on me again 46 mins later. Does this mean I need to replace the battery?
View 14 Replies View RelatedPurchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
Runs forever and very nicely on ac power.
My iBook G4 crashed on me one night, and the only way I could turn it on again was to unplug the power cord from my computer, turn it over, remove the battery, put the battery back in, plug the cord back into the computer, hold down the start button, and it would restart. Although, when it restarted, the fan would go on first, and then the computer would make the normal start sound. Some times the finder would be on the screen after I restarted it displaying a quick link icon of the hard drive. So after a few weeks, it did it again, then a few days, and then it got to the point where I had to keep my computer in the same position otherwise it might shut down.
Now, if the power cord is green everything is fine, but if I move my computer and bump the cord into the wrong place it turns from green to bright red, makes an evil buzzing sound, and in three seconds the computer shuts off and I have to restart by using the method above. If or when the power cord goes bright red I do have 3 seconds to pull out the cord before it shuts down. I then sleep the computer, put the cord back into the computer, and move the cord around until it is green again.
I took my computer to a mac genius, and when he looked at the crash report he said it was frequent, but not caused by the battery and couldn't tell me what was the exact problem. I bought a brand new power cord, but I still couldn't move the computer around to much or it would shut down.
1.) Has anyone ever heard of this happening? And if so, what causes it to be so touchy?
2.) What can I do to fix it myself?
3.) If I send it in, will they be able to fix it so that it is perfect again without having to spend more than the money assessed?
I would like to try to have it fixed. At this juncture, my only option is to send it in for $280 and hope they can fix the problem that no one seems to know what is the exact problem, or even where the problem stems from. I should add here that the battery is fully charged, and the report says it can hold about 1 hour of life, although it's more like 30 minutes, and then without warning to plug in or risk shutting down (like it used to give me) it will shut down.
This is a new problem, started immediately after moving the computer gently a foot to the left...
When computer goes to sleep it shuts down.
Then when I press the power button I hear the mechanical click but it doesn't power back up.
Then if I unplug and re-plug it'll start back up. Happens every time like this.
I've, reseated the RAM chips, repaired permissions and reset SDC (SMC? whatever you call it when you hold the power button in for five seconds after unplugging).
Ever since I sold it here on MR and got it back, there has been a problem with my 12" Dual USB iBook G3 500MHz's screen (lord, that's a long name). Whenever the screen is tilted back farther than 45 degrees or so, the backlight shuts off. I can open the casing and fix it if it's possible. Does anyone know what the problem with it is? I'm trying to get it fixed up and ready to sell back to my friend as his first Mac, and I'm trying to get every problem resolved
View 4 Replies View RelatedMy aging G4 Quicksilver is still very operable yet have had mysterious problems with mouse tracking, USB ports not being recognized and now the machine wants to shut off after being asleep for some time. Someone suggested that it could be a voltage regulation problem, but service personnel have not been able to duplicate the problem with a bench test. In short, when I have a startup problem (the startup button will start to glow, at startup and then the light goes out and the machine fails to boot) or if I find the machine turned off after I left it to sleep at night or a few hours during the day, I will open the case and shut it. This little nudge seems to be a temperary fix. Nervous it does make me that my time is short with this trusty box.

View 5 Replies View RelatedI have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.
My brother's iBook G4 (800Mhz, First Rev) has completely splattered itself and we're getting a new Macbook for him under insurance. My iBook G3 (White, 900Mhz G3..the last G3 Rev of the iBook) has a failing hard drive.
Now, could I swap out those two drives, at least to recover stuff? And is there a specific method of opening up the iBook G4 so that I don't break stuff (I've already messed with my G3..and ended up with a dozen extra screws ^_^
Mainly the aim is to salvage the hard drive and swap them out; replacing my faulty iBook G3 one with the iBook G4 one which is perfectly fine.
I have a G4 Power Mac. It's the "digital audio" model that has been upgraded with a 1.2Ghz G4 processor. It works well except for one thing. It shuts down randomly and suddenly. Then after 5 or 10 minutes it turns itself back on, reboots and runs fine. (It is set to re-boot after a power failure.)I suspect what is happing is the power supply is turnning itself off due to some kind of a thermal, self protection switch. The fan seems to work but the PS gets warm.What's the cure? Replace the power supply? If so where to get a new(er) one?

View 3 Replies View RelatedI have a power pc and recently installed some new RAM. All worked fine for a few weeks then the computer randomly shut down. I would turn it back on and it would chime but shut down again before it was finished booting. Thinking this was the new RAM I took it out and rebooted. All was fine. To cut a long story short, I now get this problem with any configuration of old RAM and/or new RAM and to allow the computer to boot successfully I have to at least take out a RAM card and then put it back where it came from...
It seems though the new RAM did trigger something but this now happens no matter what RAM is in there. Also, taking RAM out seems to reset something that makes it start up OK. Any ideas what could could causing this..?
My iBook G4 power supply failed and I'm awaiting a replacement. In the mean time, can I use the power supply from my iBook G3 with the iBook G4?

How much faster would the G4 be over my G3. I figure that after selling my G3, the G4 would only be another $200ish on top of it. Would this be worth it?
I just bought a parts ibook from ebay, but I managed to fix it, except there was no hard drive. I currently have a 6 GB HD in it with OS X.3.9 on it, but I want tiger. I have the tiger family pack, so I have a license for it. It only has a CD-ROM drive, so I am wondering if I can buy a 40 GB HD, and clone the one from my G4 onto it.
