I've a MDD G4 dual 1.0 along with the wide acrylic-bezel 20" Mac monitor with the light in the lower right corner. Yep, it's starting to look ancient. But I still have much use for it EXCEPT that it has a very nasty habit of turning itself off catastropically in mid-thought, as it were. Oddly, this behavior comes and goes in spurts. it will hit hard for a couple of weeks then a couple of months will pass with relative peace and stability. Then, back to the crisis.
Sometimes I get a warning from that power-on light in the bezel -- it might flash brighter for an instant, then within a few seconds the whole system loses power just as if I'd turned off my power strip. Other times, it pops in and out of sleep mode for several cycles, but usually this ends the same, with no power at all. Odder still, the machine has a tendency to turn itself on unaided. This can happen even after a controlled shutdown. It turns on, acts normal for 20 minutes, then maybe goes to sleep and wakes up a couple of times, then crashes. No intervention at all on my part at any time. This is not a software shutdown of any controlled variety. Anyone know what's happening? I can't tell you how much gnashing my teeth have endured.
As of a few days ago my MacBook Pro has been acting oddly. When I shut the clamshell and reopen it again a few minutes (or hours) later it's hot and makes sounds as if it is working hard at something but the display will not turn on. I usually end up turning it off anf then on again via the power button. I have a wireless keyboard attached due to damage to the laptop's own keyboard, but use the laptop's power button (which still functions). I've reattached, and reset, the keyboard a few times in case that was the problem but had no luck. It doesn't hinder my usage of the computer once it's on again but it is strange.
I have a strange problem with my late-2008/early-2009 MBP. In the last couple of days, I have been using it and the screen goes black suddenly. It happened once for just a few seconds and then recovered, but today it completely shut off-- even though the battery was mostly charged (and I had received no warnings)-- so I had to reboot.
A few possibly relevant facts about this computer and this incident:
1) I've had it over a year and never had this problem before.
2) I had the logic board replaced recently because of an issue with sleep mode. This problem never appeared before the logic board was replaced (although this may be a coincidence).
3) Both times the problem happened this week, the computer was running on battery power.
4) Earlier this week (before the incident), I got a little warning to "Check battery" or something similar. The warning went away, though. Maybe this is a faulty battery issue?
5) When the computer completely shut off, it was also running a Time Machine backup. I noticed that TM has been having trouble today-- giving warnings about errors. Not sure if this could be related.
I own the first 'remolded' revision of the Macbook released in '08 (5,1), and have had it for over a year now. Recently though, after 10 or so minutes running off just battery power (fully charged), it shuts down unexpectedly. It doesn't say the battery is low, or near low, it just shuts down. It's really annoying, I have to use the charger wherever I go. I really need my laptop so I don't really want to take it to an Apple Store and have to wait a week to get it fixed, unless it's really necessary. My software is up to date. Any ideas on what my problem is/how to fix it?
I have Western Digital My Book Pro II 2TB hard drive connected through FireWire 800 or 400 cable. The problem is that it shuts itself off unexpectedly all the time. Sometimes right after I turn it on, sometimes after 30 minutes. After turning it back everything seems to be fine, no loss of data. Anyone else experienced the same problem and can suggest how to fix it?
I got my macbook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do
I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.
Well just recently my MacBook (bought 2/17/2007) started shutting down by itself. Seems to happen after long use (3hrs) and when it starts to get hot. Also noticed screen doin a "fizzle" when using a thumb drive. Anyway went to Apple and dropped it off. They said they will run some stress tests on it and get back to me. I know there are a few things out there about this but wondering if any of you have experienced this recently or at all?
No warranty either. So if it is a logic board issue not sure... or if its a heat sink issue? Not sure what that entails to get it repaired. I was not expecting them to take the MacBook right then and there so i was sorta concerned as it has everything but... want to get it figured out.
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?
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.
i have a powermac g4 that is running fine, but when i click on the apple sign and tell it to go to sleep. It goes into sleep mode and then after that shuts down. Is this normal, I think it might be a setting a have to change but I am unsure because this is my first mac.
I 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..?
I have this iBook G4 and the wierdest thing is happening. When it is on and you bump it or move it a little it just shuts off like a hard shut down. Has anyone else out there heard of this problem or does anyone know how to fix it?
I have a 700MHz iMac G3, which froze during DVD playback and it needed to be rebooted. Now it will not boot, the gray screen comes up with the loading circle, but it will just shut down after about a minute. I have reset the PRAM, PMU and it is running 10.4. No beeps or anything when it shuts down, it just turns off.
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.
my eMac is somehow shutting down after going to sleep. I've checked the system preferences under energy saver and there are no schedules set for the machine to turn on or off. It does not happen immediately. It usually happens after a day or so. When I return to wake up the machine, it doesn't respond. I then have to start it from the start button. I don't get any error messages regarding the machine shutting down in the wrong way...just boots up normally.
I've had it for 5 years and this is the first time this is happening.
Has anyone experienced this before?
Can my machine be "infected" and controlled externally?
I 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.
My iMac G5 (rev A) shuts down immediately after i put it to sleep mode after just starting up the computer. The longer the computer has been on before I put it to sleep, the longer it takes for the computer to shut down while in sleep mode. I already did the hardware test and it said there were no problems.
I have a Dual 2.0 Powermac G5 that has been shutting down without notice. It first started doing this every couple of days. I'd have to let the computer sit for a few hours before it would run again. Now it does it more and more frequently and stays running ofr less and less time. As of now, it will only stay on for 15 minutes before suddenly shutting down.
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.!
