Ibook suddenly shuts down

hi,
i really hope this question hasn't been asked a thousand times before: when i lift up my ibook grabbing it at the front right corner (where the battery is), it shuts down quite often. i don't have any clue, why it does so... does anyone of you?
thanks.
mia

I seem to have this exact problem. My iBook is only a couple months old but is nearly unusable away from its power adapter.
- The crashes happen only when on battery power and the computer is moved
- The right front seems to be the area causing most of the trouble
- It has never crashed while on battery power and on a desk
- The crash is instant and exactly if the battery was suddenly removed
- There is no freeze or warning
- There has never been a message relating to this on restart
- Crashes can occur at any time - from the boot screen on
- The crashes happen at any charge level
After many trips to the local Apple store (The Woodlands, TX) I have given up on them. Most of the time they claim it is a software issue. Even though: it has crashed at least 100 times on me without the power adapter and never with the adapter etc. Of course even though I can get it to crash on cue at home, it never seems to want to crash while at the store.
On my last trip they installed some old spacers (left over from some very old Powerbooks apparently) to get the battery to seat better. These have failed to fix the problem. Even worse than that, after they jammed the battery and spacers back in, my mouse button is all wonky. Almost the entire right side is "unclickable" while the left side is too soft. and if you click hard enough on the right side of the button, there is a good chance it will crash. Some basic prodding around under the button with the battery removed has failed to return the button to its previous state.
I am nearly at the end of my rope here. Not only is my nearly new iBook useless away from my desk and my mouse button dreadfully wonky but my "friendly" geniuses give me the runaround. I am sick of dealing with the same uninterested people that refuse to believe maybe the battery just won't seat right and turn me away with very faulty diagnoses.

My ibook suddenly shut down and wont start up. please help!!!

hi, im new to macs so i need help! my ibook g3 700hmz was acting completly normal and i was using elmedia player on it, suddenly it went on hybernate while i was using it. i could not revive it no matter what i did and i could not shut it down so i took the battery out. now it will not start up, power on, or do anything at all. it makes no difference if i plug it into the charger, take battery out or anything. i tried to reset the PMU but had no success. i took out the ram and tried to start it but still nothing. someone sugested it could be the logic board but would it just suddenly die all of a sudden? another suggested the hard drive but it should still power on with a bad harddrive shouldnt it? could it be the dc board? the battery is low but when you press the button on it one light does come on and blinks for about 10 sec. i have no way of testing the charger but it worked fine the night before. any help would be apreciated.

It's really hard to tell whether the battery would have enough capacity to boot. Lack of bootability may be due to hard drive corruption, as well. Having the CDs (or DVD, as the case may be with Mac OS X 10.4, from which to boot could help you figure out whether that is a problem, although I would expect it to at least start up to a flashing question mark folder if it were a hard drive problem.
When a battery doesn't charge properly, the most likely problem is the battery.
The next-most common problem is the adapter. They do wear out, and it's entirely possible that this may be the cause of the problem.
Next in line for consideration is the power input (DC-in) board. This is the part of the iBook that houses the adapter port. Usually when it goes out, the adapter doesn't work at all. It won't charge the computer, and it won't run the computer. In this case, once the battery runs down, the only way the computer will run is with a battery that has been charged externally (by another iBook or an external battery charger).
The least frequent cause of a battery not charging is the logic board. The power management unit (PMU) can be permanently defective. If this is what is going on, you probably won’t see any charge to the battery at all, but, in my experience, the adapter does run the iBook (unlike when the DC-in board is at fault).
My best estimate in your case is that the battery died completely, since you were using it from the battery when this happened. My 800 MHz iBook came back from a logic board repair with a defective logic board that wouldn't allow me to use the battery at all. As soon as I unplugged from the adapter, the iBook died. It didn't just go to sleep, though, it died completely. So if you had a sudden failure of the logic board, I wouldn't expect it to just go to sleep. Suspect, in this order: battery, adapter, DC-in board, and, finally, the logic board. Because of the way this happened, unless you dropped it or spilled something on it, I would not expect it to be a logic board problem (but that's just my best assessment of the situation, based on my experience). If you want to have it analyzed by professionals, DT&T Services in Fremont, California may be your best bet. They do free diagnostics, but it would cost you shipping charges both ways in order to find out what's wrong with it for certain. They also offer the cheapest logic board repair I've found, often less than what you'd pay for a logic board without labor, and they have a six-month warranty on the part(s), but I'm not sure whether that six-month warranty includes labor. You'd need to ask.
Good luck.

IBook will suddenly shut down and not turn back on

My iBook (apporx. 5 yrs. old) will suddenly shut down while I'm working and not back on. Most of the time after it's been turned off for days it won't turn back on, although it's plugged in and the battery is charged 100%. But on the occations it does power up, everything works properly. Could my battery be completly shot?
iBook Mac OS 9.0.x

I too have that problem, but since apple replaced my battery for free, it still does that. I once heard that once your iBook reaches a certain temperature, it will just turn off the screen. usually when it happens to me, I just restart my machine the old way (control-apple-power), but it isn't so good either from what I understand! it is a bad way to work, but until apple fixes the bug, we'll just have to live!
(ps) is there any reason you still run os 9 (cause it is officially discontinued as of 2004)? you should be able to purchase mac OS X (10.2 or 10.3) from ebay or your local mac repair shop (we fix macs in palo alto, ca probably sells it still) I just wanted to inform you of this since you obviously had no idea!

Sudden shut-downs

Hallo,
I also encouter that sudden shutting-down problem on my 12" iBook 1,33 GHz PPC G4.
I've read a lot of threads in here on related stuff.
To be exact
* I had both shut-downs and display-darks, on power-supply and on batteries.
* I ran extended AHTest, it reports everything is fine.
* Power Supply colors behave ok.
* Battery does go up to 98% only. I had a replacement, it counts only 45 cycles.
* Slight tweaking or shaking the machine doesn't reproduce prob's nor help.
* Closing and opening the screen solves the display-dark issue.
So what i would like to find out is, if there is a way to tell if it's a logical board issue or a dc-in-board issue; before deciding for a replacement part or a replacement machine.
p.s. some lines quoted from system log that may tell sth:
(shutdown resetted date. reboot was at "Jan 1 02:00:33")
Jan 1 02:00:34 localhost kernel[0]: ApplePMU::CLOCK RESET! PMU WAS PROBABLY RESET SOMEHOW!
Jan 1 02:00:37 localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -127

Hey mono,
Closing and opening the screen solves the display-dark issue.
It might be that you have a reed switch problem (or an inverter cable problem more difficult to repair).
If you raise the keyboard and open up the ram shield, in front of the RAM are two connectors. The one closest to the display is the trackpad connector the other one further toward the front of that is the reed switch connector. I have a 1.33 12" logic board here and can identify the connector but since it's apart I can't tell if there's enough room in there to be able to pull that connector.
Maybe a tweezers with a long right angle tip.
In the service manual the trackpad connector has 4 blue wires and the reed switch connector has a red and black. If you can disconnect that plug that could solve your problem. The worst thing that would happen is that your iBook would not go to sleep when you close it.
So another test of the reed switch would be the next time it goes dead pass a magnet over the area just inside of the foreward edge of the CD slot about 1" to the right near the bottom of the keyboard. If that solves the problem it's most certainly the reed switch.

Spontaneous sudden shut down

Hi, I'm new to Macs--about 6 months with my iBook.
Recently, it has been suddenly shutting down, turning off with a black screen. No warning.
When I restart, it checks the disk, then stops showing a couple of directory errors. I have to turn it off then turn it back on to reboot.
Any ideas what's going on?
Thanks!

Sudden shut down (not covered by Extended Repair Program)

I started having problems with sudden shut downs on my 17" iMac G5 1.9GHz lately (actually problem started after upgrading to Mac OS 10.4.8 this week): the computer will go dark like with a power outage - sometimes while I am working on something, other times while it is just idle.
I have researched the discussion board and found that earlier iMacs seem to have a known power problem, but have not found anything on my generation iMac so far (serial # W8547***).
I have tried all suggestions - including resetting SMU & PRAM, checked power lines, downloaded the new Security Update etc - nothing seems to do the trick. I hooked up an external harddrive last night to back up data - five tries each failed, because computer shuts down at some point or the other.
System log lists shutdown causes 2 & -110...

Hi, J & F.
I am sure you have searched no only the forum, but also the support pages of apple.
If i understand you right, it happend EXACTLY after the update of the OSX. It looks tgo me as if something went wrong in this process. I would try:
a) to start up in "single user mode" - this checks whether it is something else than the bare operating system; It would give you the indication that your machine is, hardware-wise, still fine. This would eliminate the Powersuplly problem. However, it does not isolate the powersupply as faultive in case that this step doesn't work!
b) to start up in "Target disk mode" - to see whether you can get anything reasonable done. this helps you to see whether the disk can be used... nothing more.
The real solution probably comes only by reinstalling the original software from your install disk. Be sure that you have a backup of all your files!
I would try and "Archive and Install" , but do , directly after this, a "Repair permissions". If this doesn't help, i would go through an "ERASE and INSTALL". In both cases, don't upgrade the lates OSX versions, stay with the one from your install disk. only, if everything works, go and update OSX.
Hope this helps - please, post back.

Suddenly Shut Down my mac book pro, late 2011

Hello guys, i need your help.
Last 2 weeks, suddenly my macbookpro shut down, and it makes me shock.
After a few second shut down, i try to turn it on.
it just make sound like turn on your mac and suddenly shut down again.
It shut down for 3 times and more.
When i plug in the charger, it turn on.
But after i unplug the charger it suddenly shut down again.
i try to shut down my mac properly, and when i turn on again it works.
My friends say that it could be my battery, i checked it, and my battery was normal.
And i search about this issue, some people say to reset SMC, i dont know if it would works or not.
Did reset SMC will makes you lose you data or something?
Now, i must plug the charger when i want to turn on my mac.
Did this a serious problem or not? i need you advice guys.
Thanks!

No data is lost due to resetting the SMC.
But after i unplug the charger it suddently shut down again
The problem may be the adapter. Try here > Apple Portables: Troubleshooting MagSafe adapters
Hopefully your important files are backed up just in case.

My MacBook suddenly shut down and won't turn back on - how do I get it to turn back on?

My MacBook suddenly shut down after freezing up and I cannot get it to turn back on again. I tried the suggestions in the manual and none of them worked to turn it back on. Is there something I am not doing correctly? The little green light on the charger connector is green but not as bright as normal, it was charged by over 70% before it shut down, so I do not think it is a battery problem. Is there anything I can do to turn it back on? Thank you for any help given, I really appreciate it.

If it won't bong, then try an SMC reset.

My iphone4 suddenly shut down.I pluged into a charger it started vibration and got heat up in off mood. I also checked it to genius he said that its battery is ok but problem is some thing else. It is still in off mod. what i have to do?

I am having a similar odd issue. First of all this summer i took my iphone 4 to apple because my screen had quit. I could hear calls and texts coming thru but screen was unresponsive. I was a month out of warranty so the nice fella at apple gave me a 30 day warranty, then replaced my handset with a refurb. Saturday night at dinner i was on my phine and it died. I plugged it in thinking nothing of it and went to bed. When i wooe up after the charger had been on all night all i had was the black screen with the battery (red) and lightning bolt, meaning it knew it plugged in but still did nothing. So off to apple i go. They said i was out of warranty and the problem (never said what problem) would cost 170 bucks to fix. So i went and upgraded to the iphone 5 ( figured if i'm spending that anyways may as well be on a new phone). When I got home i tinkered with the old one with all the online suggestions i could find. (Cleaning ports, hard reset, putting into recovery mode, and checking indicators for water damage which there was none). Still only saw the battery symbol. I left it alone figuring i can sell off cheap and someone else can repair. Last night for kicks i plugged it in again and it came to life! It is in recovery mode (needs to be hooked to itunes to regain functionality) but showed 100% battery charge. I went to show my bf and realized an issue. If its not plugged into the wall adaptor, it wont turn on. I figured then that if i can get it plugged in and pull it up on itunes maybe it would be fine. When plugged into the computer it wont hold enough power. It thrns on shows the apple for 30 seconds, shuts off. My ending conclusion on my own is that it needs a new battery in order to be revived. Anyone think this sounds like a reasonable conclusion? Or will i be wasting money? If i can get it restored to functional, cheaply i can give to my bf (his pos lg phone is almost toast) or sell it.

IMac suddenly shutting down

Below is what my iMac tells me when it suddenly shuts down or freezes. Does this mean anything to anybody. Quite frustrating. I don't want to buy a new machine if there is some fix for this but I also cannot afford to be without my machine while it is in the shop for a look under the hood.
Any suggestions would most appreciated.

Re: Restoring windows after sudden shut down during updating

Hi everyone,
Last night I was updating my windows on my Toshiba laptop, however, my laptop had a sudden shut down during the updating process.
Now when I start my laptop, I am prompted that a system error occurred and I have to insert my windows CD to continue. I never got a windows CD, and nor have I made a recovery disc yet, so is there any possible way for me to log into windows again? I am using windows Vista.
Any suggestion would be grateful.
Thanks in advance

hi dDk,
what is the first rules of using a computer?
*never touch a running system* and of course: *read the f... manual* and *make backups often*
ok this was a bit hard... but this is a common failure to make an update without saving....
now lets see what we can do....
- i assume that there is no possibility to start in safe mode...
- hdd recovery is not possible...
- you have neither a systemdisk of vista nor a system backup
now you are in operators hell....
- see a servicepartner and ask for assistance, for a small fee he is able to setup your original system
- get a vista/win7 istallation cd and install it, be aware you loose your hdd backup funktion!
- try to repair with a "system-on-a-disc" like winpe or bartpe
- try to make the hidden recovery partition visible to a os booted from cd and run recovery agent from there
if you killed your recovery partition.... bad luck

Dual 2.3 GHz G5 suddenly shutting down

We have a Dual 2.3 GHz G5 (production week 10/29/05, Power PPC 970 v.3.0, with 2.5 GHz RAM), running OS 10.4.8. This machine has started to suddenly shut down - like someone pulled the plug with no warning.
After turning itself off like that, we need to wait around 20 minutes before it'll start up again and keep running. Once it has shut itself off, we cannot get to the logon screen without it shutting off suddenly again. After letting it cool down for 20 minutes, it'll run again. So it seems to be heat related in some way.
I've run Temperature Monitor and iStat, and everything looks OK. Of course TechTool Deluxe didn't find anything (does it ever?).
The machine will run for 2-3 hours under load just fine, but will suddenly click and shut off at some point - even when not under a load.
I've checked the System logs and Console logs and can see nothing, except once the system log reported "ApplePMU::PMU forced shutdown, cause = -122"
The other times there was no log entry, like it shut down too fast for the log to be written.
Is the power supply going bad? Is there a temperature sensor which is too sensitive?
We'd appreciate any help or suggestions.

o maybe there is something RAM related, but I can't
imagine that RAM would shut the machine completely
off. Can it?
I believe the problem is thermal related. You may have a processor acting up. Try running Hardware Monitor once, and see what your internal temps are running.
