Sudden lack of power, So far no luck.

I did the restore, however the iPod just has the "very low battery" screen on, nothing's changed in almost an hour so far. The iPod doesn't seem to show on the iTunes either. However it did go through the restore routine though. Any ideas?
meagain.

A combination of the two worked. Using the restore helped
to reset the power bar, however it still wasn't charging
for some reason. All I received was the too low message or
just the apple screen. When I read the site for the power
it corrected the charging issue, which was that I was using
the USB in stages, basically I had coming out of my laptop
one USB splitter, which fed the iPod. Aparantly that wasn't
doing it for the iPod, so I just went directly from the
laptop to the iPod and it's charging normally. Thanks for
the help.
methankful.

Sounds like you need a #1SMC Reset
1. SMC reset
>>Instructions to reset SMC
Disconnect other non-Apple and external hardware except (if applicable) a mouse and keyboard until your finished repairing your machine.
Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc. If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.
Will not hurt the machine resetting if it's not broken.
Other related hardware problems (optional):
Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.

"My Mac was stopped suddenly by a power cut. Could this be relevant?"
Sounds very relevant.
Do you have access to another computer with Numbers installed?
If so, do your files open properly on that computer?
If so, then the problem is your computer itself, which is best posted in a different forum.

Sudden loss of power, shutdown

I have a Imac 9.1, attached to a UPS and twice in the last month while doing the most trivial of things (today scrolling an internet page) the unit suddenly powered off? Just "Blink" screen black and power off. I'm not sure what it is.
My question is, is there a "systems event" log that the system captures when things like this happen which point to something that was going on right before the lights went out? Or is this merely a matter of waiting till it happens with some degree to repetitiveness that I take it in for an analysis at Apple. Any advice would be appreciated.

Hi, if you think it's the UPS! try going to the Website of the manufacturer, FAQ, Help, Contact Us...
The sudden loss of power may well damage your HD..My advice, don't use the UPS till you are sure of the reasons for the power outage..Use a good Anti Surge unit until then...L

Old Reliable G4 mirror suddenly won't power up....YIKES!!

my trusty, G4 MDD, almost 4 years old now, never had problems, all of sudden will not power on at all when the power button is switched on....I tried resetting the button on the motherboard next to the battery (PMU?) and still nothing...
from my research, it sounds like a power supply, but is there any thing I can do at this point to at least try to get this thing powered up?
I'm not really anywhere near a mac tech, but I do have other issues
a) in case it is a power supply and it needs to be replaced, will it affect the files on my boot drive?
b) I do have a spare 733 Quicksilver...I had been running a separate audio drive that I'm sure I can probably install on the Quicksilver to at least retrieve my audio files, but if I remove the boot drive on the 1.25 mirror door, can that simply be installed on the Quicksilver also to retrieve some other very important stuff...
HELP!

so regardless of whether it's the boot drive or the supplemental drive, it doesn't matter?
Correct. Either one can be installed in an enclosure and will be seen as an external.
now, if I install the old boot drive from the MDD into a firewire enclosure, can I plug that drive into my spare Quicksilver and boot from that? if so, how do I do that? (provided the drive isn't messed up)
Go ahead and try it. Connect the external device to to the QS and check System Preferences. If it is bootable, System Preferences / Startup Disk will list it. At that point you can select it as your startup drive and restart.
By the way, I suspect you already know this, the power supplies of the QS and the MDD are not interchangeable.

Lack of power?

Hello everyone,
I've been reading this great forum to find some answers but I'm still confused (so forgive starting a new thread about this)
I have had random crashes mostly when browsing internet but sometimes also when doing something else. Everything works fine and then suddenly computer boots itself without bsod or anything. Usually when this happens internet connection stops working until shutting down computer and doing the powercord off -trick.
I've been thinking maybe this is psu related, but what really confuses me is that I NEVER have any problems playing hours games like Far Cry. Should't that be much more loading (not sure if thats the right word) for psu than for example browsing internet??
I've tested memory with Memtest, no errors.
I have also changed my keyboard from ps/2 to usb w an adapter.
I am not oc:ing.
Really would appreciate any advice before buying a new psu or something.

You didn't give the full system error log messages but if you google search and compare yours to others you should be able to find out more information about what's causing them.
I've been trying to and it looks like it could be a bad driver thing as you said. Maybe I should try reinstalling Windows and all drivers.

U410 sudden loss of power

Hi,
I recently bought a U410 which was working fine apart from a random loss of power. The machine would switch off suddenly in a number of situations (both when being used fairly heavily and when idle) and both under battery and mains power. When it switched off the machine was not excessively hot. When turning it back on the machine booted fine, had adequate battery power and did not report anything in the event logs other than an unexpected shutdown. As the machine was only a couple of weeks old, I returned it to the store and (with a bit of convincing) managed to get a refund. Since this appears to be a fairly isolated issue I bought a new U410 but unfortunately within a couple of days this one was also experiencing the same issue. I would rather fix the issue than take this one back since the U410 is otherwise a very nice machine.
After a bit of research on these support boards I found a few threads referring to different potential causes, but no definitive cause. Everything tried so far (fully updating drivers, bios, windows etc) hasn't alleviated this issue. Did any definitive cause of this issue ever get found?

hi stevejefferies,
Welcome to the Lenovo Forums.
Most intermittent shut down / power loss issues that I've encounted is due to overheating or a faulty component inside of the PC.
Here's what I would do if I was in your case:
1. Monitor the temperature of the HDD,CPU,GPU by using HWMonitor.(the Core i-series CPU has a TJ max of 100 C before the unit shuts down)
2. If there's no sign of overheating, eliminate the OS and the preloaded apps as the issue by doing a fresh OS install. If you're running Windows 7, you can get a Windows 7 ISO on this website then install all the drivers (keep windows update disabled for the meantime) and observe.
If the issue reoccurs, I recommend you contact lenovo to report the issue and have it serviced.
Regards,
neokenchi

Sudden Loss of Power... but computer works fine...

I've had my dual 1.8 for about three years now... it's not in the category of G5's that had the power recall.
I have it hooked to a Belkin UPS backup, but for the last week or so, the computer will abruptly lose power. I haven't installed any new apps or hardware for some time (new RAM about 2-3 months ago... but system profiler says it's all good).
Any thoughts as to what's going on? I've backed up all my work, similar to the peeps that built nuc fallout shelters back in the day. I'm awaiting the big one!

I have the same problem on my G5. Just randomly powers off suddenly. It happens in spurts and then stops for a while. Usually happens when I am working in or loading ProTools software...but not always. I think the power supply can't handle extra power needs or something like that... One time turning off my air conditioner seemed to help... Hard to say though since it happens randomly... FRUSTRATING!!!!! not in the list of G5's for the power supply recall... What do i do???

OK, what is it about G4 towers suddenly w/o power?

I got my dual Gigabit Ethernet G4 tower from work when they got rid of Macs about 4 years ago (keep hoping they'll change their minds). When I first got it I had the typical no power problem and a new battery solved the problem (but I had to order it from OWC, the one I got at a local store didn't work).
Right before Christmas we shuffled furniture around in the family room and unplugged the Mac. Now it's dead again. I've tried two different new batteries (one from OWC), I've done the simple reset and the sit for 30 min reset and the sit overnight reset and the take out all the ram and the cards reset. Still nothing.
Now, it appears I'm getting something from the power supply because when I had everything plugged in, the monitor was showing that it was getting power. Does that mean that it's more likely the motherboard than the power supply?
I know it's had a good long life, but I'm really sorry to see it go. I got a good deal on a core2 duo Mac Mini. I think the g4's likely dead; if the problem is the power supply, it's going to be a bear (and $$$) to replace, and although I see motherboards on eBay for a good price, I know I could get that in, struggle to figure out how to replace it, and the darn thing still might not work. Plus the motherboard I just purchased would also be like 8 years old.
So...what is it about G4 towers and suddenly not starting up? I see this problem frequently on the support boards. I love Apple (right now I'm stuck on a Vista laptop and...ugh), and I know that this tower had a long life, but doggone, why do they just suddenly drop dead without any warning?

If you have a meter, unplug the AC power plug from the wall and wait a minute, then measure the battery in the holder, working. If you do not see 3.2 Volts or higher, the battery, regardless of its history, is not working.
After fiddling with any Hardware, you should press the tiny reset button for a quarter minute \[with the Mac nominally off, but the AC power plug plugged in]. Then wait at least five seconds before proceeding. Avoid momentary presses, they can crash the microprocessor that controls the clocks and drain your battery in a day. If nothing seems to change, do the procedure again.
If you still have no response, disconnect the drives, remove everything except the processor and memory, do a reset, and try for a startup chime.
If no chime, use this diagram to look for Standby Power on pin 9 of the main DC power connector:

Nothing has ever been overclocked on this system.
Everything is plugged into a Belkin Surgemaster powerbar.
I haven't mentioned the power supply. I'll get to that. I have been using an ANTEC NEOPOWER 480W POWER SUPPLY (ATX12V DUAL 12V RAILS ACTIVE PFC W/ DETACHABLE OUTPUT CABLES) for about a year on this system without
any issues. One morning, I wake up, hit the power button on my coolermaster case, and nothing happens.
CPU fan won't even spin. Nothing happens.
O.k., blown power supply, I think . . . .
So I take out my Antec and put it in another system. That system turns on
without any problems.
Hmm . . .
I come here, and I read posts about
potential compatibility issues with Antec power supplies. But if it's a compatibility
issue why was my system working for about a year?
O.k., fine. I'll buy a Enermax 535W EG565P-VE FMA 24P (115/230 VAC) power supply.
I just plug it into the mainboard (nothing else). Hit the power button . . .
The CPU fan spins for half a second, and then nothing.
Did my motherboard just suddenly die for no reason?
Any suggestions?

Pull the AC plug from PSU and set cmos in clear position with battery removed for atlest 20 minutes perhaps longer .
Then try to post the system barebone .
Just cpu,1 pcs memory in slot 1 , gfx card , and keyboard in PS2.
No usb devices at all including card reader and no pci cards harddisks or cdoms/dvd/floppy.
It could also be caused by a short or a malfunctioning fan connected to mobo.
Try to disconnect all case fans from mobo headers if you have any connected to additional fan holders.
The chipset fan can also be disconnected momentarily just to see if it posts.
If none of this helps , replace cmos battery and try again .

MacBook Pro suddenly looses all power and turns off

Hi folks
Ive experienced this twice in the last week, and jut pray that it doesnt ever happen when im working on an unsaved Logic Pro Project.
Anyhow, ill be working away and then screen goes black. All power is lost to the computer. You cant turn it back on untill you insert the power adapter. Both times it happend the power to the mains has not been plugged in. Once you install power Then it picks up power and it restarts.
Has anyone ever experienced this? Is this a known issue? Im just scared as tits that one day im going to be in the middle of something really important and its gona go wacko on me.
The battery is not dead, when i rebooted on the first time battery was at 16% second time it was at 22%

same here.
my MBP started doing it recently.
for once, battery goes out of juice pretty quickly.
but there is still some juice left (last time - 17%) and suddenly the machine just switches off... like that... no warning, no sleep, nothing....
I did the "battery formatting" and also reset PRAM (?) (switched it off, took the battery out and kept power button pressed for 10 secs)
I do not like this behaviour. Interestingly, the battery has been replaced (there was a battery recall action about a year ago)
Awaiting some hints re: what can be causing this...

Imac's sudden crash, like power failure. starts again 30min later

Hi all,
my imac crashes sometimes very suddenly, like in a power failure. it doesn't force quit or shut down, it just goes like somebody pulled the plug.
it's usually possible to start it up again after 30minutes or an hour.
the plug and lead seem to be fine. i tested it on another mac.
the obvious suspicion would be overheating, but how can that be caused so suddenly (and how can i fix it)?
thanks for reading
i appreciate any advice

Get a temperature monitor.
There's a free widget, +iStat Nano,+ that a lot of folks use. There's also an inexpensive app, +Hardware Monitor,+ a much more comprehensive and customizable version, including a 7-day history with all sorts of fancy graphs, etc. There's a free version, called +Temperature Monitor,+ that may do enough, too: http://www.bresink.com/osx/HardwareMonitor.html
Having the history may help you figure out what's happening.

Sudden loss of power while working on battery

My MacBook Pro is suddenly shutting off while I am working on battery. The last time this happened, I had my battery fully charged, and yet, my computer completey shut off without any warning (about half an hour or so of battery use) while I was watching a slideshow of pictures. This had happened to me twice thus far.
What sort of problem am I having? Could this be from some type of virus? Any system malfunction? I am also wondering if I need to run any system check, just to be sure that my hard drive is working properly. Any help would be greatly appreciated.

"Check Battery" indicates that the battery is failing. If it's less than a year old, you may be able to talk Apple into replacing it as defective. If it's three or more years old, it hasn't been "exercised" (used and cycled) enough during that time and has died a predictable natural death for that reason. If it's between one and three years old, it's still failing, but the reason is less clear. Replace it and you'll be back up and running normally soon.

Imac sudden loss of power

My imac will suddenly lose power and wont restart unless i replug the power cord. I have had the power supply replaced but still have this problesm.

I had the same problem with iMac early 2011, which had aproblem with the power supply and the reseller in Amman did not change on the warranty. Anyway we ordered a new power supply "Part # 661-5299" from another reseller and installed it. It worked only one hour and started to loose power. And did not boot againg until the power cable was repluged.
We managed the figure out that the new power supply -changed layout- does not allow the air flow of the fans to cool it. We also managed to repair the old power supply, sinse its layout allows the air folow throuh it.
We need some one from apple to confirm or comment on this issue, this a complain on Apple, I hope to see an oficial reply from Apple
