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.

Sudden shut down battery problem, factory reset and SW update/repair did NOT help

Hello everyone, i have a "sudden shut down problem" with my Xperia Z1 C6903 too. Sudden Shutdown always happens at about 70% for the first time, after been fully charged. I cant turn it on right afterwards but if i wait 1 min. it works. However sooner or later the phone, somewhere between the remaining battery, will repeatedly shut down again. I couldnt find out what triggers it and android battery test show that the battery is ok. I am not an expert with these devices, but i hope it is a software or calibration problem? There is a similar threat which points to the solution of using Sony PC Companion Software repair, i tryed it twice and it did NOT help! edit:I havent changed the device after PC Companion repair step, thus no other Apps are running and no energy managment has been configured (stamina mode) edit 2:hidden battery info * # * # 4 6 3 6 # * # * shows:...battery health: goodbattery voltage: 3969 mVbattery temperature: 36.6° C...is there a way which gives me more details than just "good"? And what does that even mean?

Hi, I have exactly the same problem after upgtading my phone to lollipop. I tried repair from PC companion and facfory rest, but no luck.
Do you think it is Because of the battery? Never had this problem before upgrading to lollipop. The other thing I notice is when the phone suddenly shutdown (baterry jump from 50-60% to 0%), I just need to plug in my charger and wait a moment before turning it on, then here is the problem.
1. Sometimes the battery indicator shows 50% or slightly lower than before shutting down.
2. The other times, it will show accordingly that the baterry is out (1% because it's charging)
3. Most of the times, there is a message "android is upgrading...", when turning it on.
Any idea how to solve this problem?

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!

I was charging and updating my mini ipad last night when it suddenly shut down and will not turn on since then. What do I do to turn it on again?

Try this - 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. (This is equivalent to rebooting your computer.) No data/files will be erased.

My iphone suddenly shut down and it not trun on what is the problem?, my iphone suddenly shut down and it not trun on what is the problem?

hi
i don't know why my i phone suddenly shut down and not be on at all
may u halp me ?

Assuming that the battery isn't empty (and it can take 10 to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the equivalent of a reboot.

Connect your iPhone to a power source (computer, wall charger, etc) and hold down BOTH the power AND home buttons for about 10-15 seconds. If all goes well you should get an Apple logo. Try it even if you think it won't work, and patience is key: 10 seconds is alot longer than one might think.

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.

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?

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

Macbook Pro (2012) sudden shut down, cant turn on, cant charge

Hi all,
My Macbook Pro(2012) was working well last night and i saw the battery shown at the top is showing 22%.
When i plugged in my iPhone4 to it, it auto shut down.
When i try to turn it on, it doesn't work. it turn to be comepletely died
I thought it might be the battery has dry out, so i plug in the AC power and the adapter shown a week green blinking light...
I press the button at the left to check the battery left, it doesnt show any....
My warranty just ended last week, so i sent in to do a diagnostic test on the last day of my warranty at apps store. They said it is ok.
But now....
anyone encounter this problem before?
(sorry for my poor english)

i face the same problem last night
now my macbook cant start after sudden shut down
my problem is exactly same as u...i
called apple centre and they said it may be two
possibility whether the battery or mother board crash...
hopefully its not the motherboard cause it will cost a lot to
repair the motherboard

Thinkpad X201 usually suddenly shuts down!

Dear all!
I have two problems with my Thinkpad x201.
1/ When I use it with battery and charging then I plug adapter out, it suddenly shuts down. I take it to my office or repair service and do the same but it not suddenly shuts down.
2/ it has been running fine but always suddenly shuts down in an instant, as if somebody turned off the power switch when temperature CPU up to about 55 degree C (using battery only or adapter or adapter + battery). But I take it to my office to use or take to repair service, it not suddenly shuts down. => Use it at home suddenly shuts down when CPU up to about 55 degree C. Use at office or somewhere else not suddenly shuts down whatever temperature CPU up to about 55 or 60-70!
I find some topic talk about this problem but haven't got any good solutions. I would like hearing all idea. Thanks all!

Had the same issue with the X1 carbon. send it in as it likely has a bad motherboard.

Early 2009 suddenly shuts down or won't startup

Hi, I've recently been having some problems with my mac pro 2009. It will suddenly shut down and won't restart or if left for a while won't startup.
Sometimes if I press the power button it will sort of startup but then suddenly turn off during the initial powerup (before the screen turns on).
I brought it in for repair and they replace the power supply, called apple and end the end they said they reset something on the motherboard but couldn't really find what was wrong... Has anyone else had this problem and found a solution?

Hi Phil,
Has anyone else had this problem and found a solution?
I hate to be blunt, Phil, but the real solution is to get Apple to give you a replacement. You're within your rights as a consumer to have a perfectly working Macintosh. Most of us do. I haven't read a bad report on these machines yet, but if it's not working right then something is wrong.
Good luck.
Steve

My laptop suddenly shuts down even doing nothing

so i got a toshiba c660 satellite laptop. everything was good until one day when i was using my laptop, it suddenly shut down. then i try to open it again, while in the starting windows logo, it shuts down again. i tried to open it again, then the launch start up repair command showed up. i tried the start up and i can use my computer again for long hours. but after letting it rest for few hours, the same thing happened again. what could be the main problem? and what should i do in order to fix this? and another thing when i use capslock the key 4 r f and v do not function. but if i hold shift i can type 4 r f and v. is that related to the sudden shutting down? please help me. thanks in advance.

You're system inexplicably dies, do your rebooted sessions last longer if the system is allowed time to cool down before restarting.
If the system is immediately restarted after halting, does the immediately restarted session halt after barely a few minutes or even seconds?
Youre description has the hallmarks of a struggling CPU inadequately cooled by a fan bogged in dust.
An inexpensive can of compressed air might be the solution and this site along with the rest of the web is repleate with instructions and mundane tips of how to most effectively smot dust from your notebook.
It isn't rocket science, but it shouldn't be done while the system is powered on, seems obvious but the poker card in the bicycle spokes sound effect from shooting air into a spinning fan also damages the fans ability to remain useful by Christmas, perfect excuse to buy a whole new laptop.
