Battery failure

Hi Guys,
My battery seems to have gone bad all of a sudden. My MBP now can't run without the power supply plugged in! Once I take out the power supply, it seems to cut power off, just like when you hold down the power key for several seconds to do a brutal hard shut down. And when you go to power it up again, it makes a few normal sounds (like the DVD player, but then after 2-3 seconds, it turns off in the same way). Bizzare...
The battery was changed out under the battery replacement program about 2 months ago.
Any ideas?

have you checked in here?

my battery did the same yastaday, and this morning i
had a new battery delivered. Thats is just extremely
fast!
ViperJ already had the battery replaced, and is still experiencing the problem.
Your issue was identical, and resolved with a new battery?
Lucky with the fast battery delivery, still waiting weeks for my 12" powerbook replacements. Sent in for the MBP battery replacement yesterday. I assume that you are in Europe, and you enjoy a faster response time for batteries than we do in the States. Hopefully a new battery will fix the problem.
This is not the first problem with my MBP, it has every whine and heat issue, which I will live with, however, this is the first issue to cripple my machine.
Thanks for your input.

My IPad1 has completely shut down. It has no power. I have tried a restart and a reset with no results. I have tried charging through the keyboard dock, the wall charger and my Macbook Pro with no results. Is this a complete battery failure?

My IPad 1 has lost complete power. I have attempted a restart and a reset without results. I have attempted to charge with the keyboard dock, the wall charger and connecting to my MacBook Pro. Again no results just a black screen. Is this a battery failure? I am in Mexico for another 6 weeks and hoping to find a solution.

Cathi-
How long did you have the iPad connected to the wall charger? A completely dead iPad battery may not work until it has been charged for some time - maybe a half hour or more. I suggest leaving it on charge overnight, and then trying the reset.
The MacBook may be able to charge the iPad if it doesn't go to sleep, but it will be extremely slow. the Wall charger is definitely the best way.

IPhone won't turn on... possibly a sudden battery failure?

Hi,
So my iPhone was working fine, i received a call, put it down... but next time I go to check something I push the home button and nothing happens.
I've tried turning it on - nothing, charging it - nothing, taking the sim card out etc - nothing.
I tried calling too, and just goes to voicemail.
I bought it off a work colleague as a replacement for a lost one, so I have no idea of the serial number, and its definately out of warranty.
Any idea what the problem is? Feels like a sudden and total battery failure, but I don't even know how I'd get that sorted/replaced!
Please help me someone!!
Thanks, Matt

Does it charge if you connect to the adapter? If yes, let it charge for about 20min. then connect in recovery mode: http://support.apple.com/kb/HT1808
If it does not charge, contact Apple to get it serviced, see these details about the battery replacement program: http://www.apple.com/support/iphone/service/battery/
or more on the Out-of -Warranty Service here: http://www.apple.com/support/iphone/service/faq/#warranty7

PXI 8156B Battery Failure and restore harddrive.

Hi,
I am working on restoring a very old system built using PXI8156B, attached are the snaps.
The system has damaged OS. I want to restore by ghost image which was captured just before final system was ready for operation.
The CPU module has battery failure which cause "Loading defaults" thereby booting from C. I tried making boot sequence "A,C" but was no success.
I would like to know how do I restore the battery..? There doesn't seem removable battery.
How can I restore the ghost image if battery solution fails..?
Kindly advice.
Thanks and regards,
Kunal

I would like to erase a partition that I have on my 30gb internal harddrive.
Do you have more than one partition on the HDD? I suspect you have only one since the HDD is only 30 GB.
Your computer is now 8 years old, as is the original HDD. The average life of these drives is 3 to 5 years, so your HDD is well past old age. You may be getting the error messages because your drive is failing.

Premature CMOS 2032 Battery Failures

There have been many reports in this forum lately concerning premature CMOS 2032 battery failures.
If there truly is a common CMOS battery problem with MSI systemboards
we need to start to find the solution by identifing what vendors battery is failing and on what boards.
My mobo is MSI K8N Neo4 Platinum (G52-M7125X1)
My original CMOS battery was a KTS Lithium CR2032
It lasted about 1 month then the systemboard failed to POST.
I replaced it with a Energizer Lithium 2032
It has worked for a week so far.
The 2032 is a Lithium-Manganize Dioxide 3.0 Volt Button Battery.
It is designed not for recharging.
Life expectancy is least 2 to 4 years
A new 2032 battery unused and right out of the package measures 3.26Volts DC.
The new 2032 battery in the motherboard with AC power on, measures 2.97 Volts DC.
A defective KTS CR2032 battery out of the motherboard for days measures 2.97 Volts DC.
A defective KTS CR2032 battery in the motherboard with AC power on measures 1.41 Volts DC.
I used a Fluke Series 77 Digital Multimeter for the measurements.
My Phoenix-Award BIOS Version 1.4 - PC Health Status of the good Battery = 1.66 Volts
I have no idea what that means other than the BIOS is not reporting accurate battery voltages.

Battery failure although my battery doesn't fit the exchange program?

hello there!
i know there have been a lot of threads about the battery life and failures in the macbook pro but i don't know which one fits my case...
my mbp is a week 13 and has no problems at all. i don't use the battery that often - by now i have 14 cycles.
my battery's serial number doesn't fit the exchange program but today happened this odd thing:
i used my mbp on battery for less than two hours and the battery symbol said that i still have about 50 minutes of battery power. all of a sudden it turned off (as described in many other threads) without any warning and i couldn't turn it on without plugging in the power cable. when i turned it on it started from deep sleep mode (dimmed desktop).
...of course i did reset the pram and stuff - but what is going on? as i said i don't meet the exchange program for faulty batteries but still it doesn't seem to work proper.
what can i do?
thanks in advance, guys!
j.

hi and thank you all for your replies so far!
over the weekend i took some screenshots showing the various total of mAh. i have no idea if that is normal like this? and the battery is behaving normal again, no random shutdown... you can find the images under the following link...
http://www.propaganda-pixel.de/mbp/mbp.htm
in addition i added a photo of my magsafe... now that it comes to the battery issue i got slightly concerned if this crimpy cord should be like this (not that this thing starts to melt on me!).
when i transport my mbp i wind the cord around those two hooks and i never pull the magsyfe by the cord out. but still it looks like this.
the power cord is from a week 10 macbook pro which i got exchanged for a week 13 but i had to keep the cord...
i know, this has nothing to do with the battery issue and no, i'm not paranoid - just now that i started this thread i thought i could add it...
so my questions are:
- shall i request a new battery considering the various mAh indications?
- shall i request a new power cord? or does mine look normal?
why i ask is because i don't want to request something when there is no need for a replacement.
thank you all!

T500 Battery Failure and Replacement Options

The battery on my T500 recently "failed due to normal wear" and will no longer hold any charge. It had over 1000 cycles in a little under two years of use, so I guess that's not to be unexpected. The failure happened suddenly though (went from 2 hrs of normal life to no charge overnight). I tried reseting the battery through power manager to no avail, so I'm looking for a replacement now.
I'm currently looking at a couple of options and wondering if anyone has experience with any of these:
Stock Lenovo (I assume it would be the most reliable, but also most expensive at $179) http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...
C&K on Amazon (Claims to be genuine; $136) http://www.amazon.com/Lenovo-ThinkPad-40Y6797-Thinkpad-Standard/dp/B001TQ6VQ6/ref=sr_1_35?ie=UTF8&m=...
eComElectronics (Claims to be genuine, although some older reviews say it's non-OEM; $97) http://www.amazon.com/ThinkPad-SL-Cell-Li-Ion-Battery/dp/B000CBG0XI/ref=cm_cr_pr_product_top
Assortment of non-OEM batteries on Amazon ($25-$60) http://www.amazon.com/s/ref=nb_sb_ss_i_1_26?url=search-alias%3Delectronics&field-keywords=lenovo+t50...
Do #2 and #3 seem fine? Even though they aren't sold through Lenovo, would they still be eligible for the 1 year warranty?
What about the non-OEM's? Are the price savings not worth the hassle of getting a lemon and the compatibility warnings from the power manager?
Thanks

if they are an official resellers then you can claim warranty from Lenovo, otherwise you would have to get the warranty through the retailers themselves.
Non-OEM quality can vary, since there are so many of them, it is hard to give you any sort of advice as to what you would expect.
But you could try the 6 cells Boston Power Battery, they have 3 years warranty, and priced competitively. They are the only non-OEM battery i would buy.

Battery failure and loss of connectivity

I have an older iBookG4 10.5.8, currently running Safari 5.0.1. The battery is getting old, will not run for more than 30 minutes so I leave plugged in. I have two questions:
1. Does clock function fail if battery power get too low, if so does this cause other failures?
2. Why is my Safari always losing internet connectivity (Wireless). The router is new (today), I replaced my old Airport (today) and I continue to get meaasges "You are not connected to the internet" I then must trouble shoot and re-try. I usually can get back on line but it is getting old always having to trouble shoot connectivity.
Thanks

I have a 1.2 GHz G4 iBook running 10.5.8. I was having similar problems running on battery. I managed to source a replacement battery from Hong Kong. I now get more time running on the battery but it is still unsatisfactory as battery drain seems to accelerate and the computer shuts down.
I have had similar problems with Airport connectivity which is inconvenient to say the least.
My iBook is probably six years old and is probably due for retirement.

OS X doesn't load after battery failure

Hi!
I have a mid 2009 MacBook Pro and my battery is almost dead, today I forgot to connect my Mac to the plug and the Mac just shut down due lack of battery (i don't get my warning anymore). When I tried to boot again, it gets stuck with the Apple logo and the spinning wheel
What I've tried so far:
> boot with partition recovery and fix disk and permissions
> reset of PRAM and NVRAM
> tried to boot with safe mode
None if this worked! not even the safe mode. I don't want to install everything again, though I have backups on my time capsule and I am safe on what regards data.
what else can I do before I go with the install?

Hi!
I managed to fix it, I had to install OS X through partition recovery and it worked. Now I have some libraries corrupted like aperture, but I am rebuilding it just right now. All should be fine now.
About the battery, no, it isn't recharging okay. Nowadays I can't last with battery for more than 40 minutes, I'll have to replace my battery soon...

Battery Failure and Kernel Panics. Help!

Hi all,
Thanks in advance for your help.
About a week ago, after I had left my computer alone for two days, it randomly shut off when the meter up top said it had 40 minutes. Then, when it was closed in sleep mode and I opened it, it told me it had to be restarted--which I, through reading the forum, found out is a kernel panic. Since then it has not given me any more kernel panics, however, it consistently turns off at about the forty minute mark. This is what I have done so far:
attempted to recalibrate the battery, which hasn't worked/I don't know if it really can because it doesn't get below 20% without shutting off. (btw, when I turn it back on, with the plug in, the battery is not dead, it's at around 20%).
have done the first three steps in the x guide to kernel panics.
Does this sound like a battery problem, and if so how do I solve that?
or does it sound like a kernel panic, hardware problem?
Thank you so much for any help, I desperately want to fix my computer.
Besos.
ibook G4 Mac OS X (10.4.8)

Hi alby23,
Welcome to the Discussions.
If your computer is two years old, it's in need of a new battery. If you open System Profiler (Apple menu>About This Mac>More Info) the battery's capacity and charge cycles will be listed. If the Capacity is ~2000 you have less than 50% of a new battery's which is 4400mAh.
You may be able to solve part of the problem by resetting the PMU. That may get the time/percentage back to a more accurate number. If that doesn't help, get a new battery.

How do I get a warning for battery failure

My Macbook pro is only a week old, and it has already faded to dead without a warning. My last mac used to tell me when I was at 10 or 15 % battery to find another power source. Do I have to set this to give such a warning, and if so, how do I do that?

Return it for a replacement or replacement battery.

CMOS Errors/ battery failure in a Satellite L45

I have a Satellite L45-S7423 laptop that is approximately 1.5 yrs old. To give a bit of history on this baby..a week before the warranty ran out, the computer stopped working so we took it in to be repaired and it got a new motherboard and I believe power supply.
Fast forward 6 months to now, and as of last night I have started getting a black screen on boot up that goes to American Megatrends. There are a bunch of self checks (I assume thats what they are) check out as ok and then it beeps, and goes to a second page where at the bottom it says "CMOS battery low, and something about the date and time not being set. I have options for F1 to load defaults and F2 to enter set up. Pressing F1 loads Vista properly.   The computer now thinks it is permanently March 4 2008...but the time runs as you would expect. It just is in accordance to either 11:00 or 12:00 when I reboot.
I have noticed today after the reboot, that my antivirus vault settings have now been lost and I also started having issues with opening websites (security certificates not valid so it says or it completely blocks a regularly used site from opening). Since the AV isnt working properly anymore I disconnected from the wireless network I use and turned off the wireless capability.
I run this computer almost non-stop, it has a chill pad after the October issue, and is updated regularly. I do run down the main battery at least once or twice a week and recharge it completely. Most of the time the laptop is on AC power though. This issue came up after it was unplugged during house chores and my husband and I both forgot to plug it back in. At most it was unplugged for a little over 2 hours. I plugged it back in for 24 hours, and the most recent reboot still brings up the CMOS message. There was an SD memory card in the card reader when I rebooted which I had forgotten about. The only other oddity is that these problems started after a windows update ran on 3/13.
What can I do for this? Is it something I can fix by replacing the CMOS battery? It is NOT under the main battery where it was suggested to me that it might be....does this mean its on the motherboard? If I press f2 for set up, what will happen? I also have a prompt to press f12 for BBS POPUP. Thanks for your help and time.
Solved!
Go to Solution.

OK, I attempted to disassemble the laptop following the "destructions" that were provided in an earlier post.   This portion of the project went extremely well...the directions were really easy to follow.
The bad news is as follows.... I found the CMOS battery.  Either Toshiba, or the manufacturer of the mother board, american megatrends, soldered the stupid thing to the friggin motherboard. I realized that this is above and beyond my level of skill, so I ran down the street to a small computer repair shop nearby and swallowed what little pride I have left.   I asked them if in fact my suspicions were correct in that the CMOS battery is soldered to the motherboard and they looked at it and went....EWWWW.
I truly appreciate their honesty b/c they wont even touch this because they do not want to fry the motherboard. They reccommend that I contact Toshiba at this point. I will keep these folks in mind if I need computer repair work done in the next few years...
The experience was not a total loss to me though, because I now have a very good working knowledge of what different things look like in the laptop. Even better, I put it back together and everything that did work, still works...haha.   One thing I did notice is that the repair place failed to replace all the screws...
I appreciate all the advice. I did try taking the laptop battery out and running the computer for several days on just AC power...in 5 days it went from March 4, 2008 to March 6, 2008.   I will post an update when I hear from Toshiba...

T60 Battery failure

Hi guys. I have a problem. I have laptop T60 with original battery. The last night everythins was OK - the condition in Power manager was GOOD, charging cycle - 145. But today I cannot ude my battery - the battery indicator just blinking and when I tried to use laptop on the battery - it doesn't work. Power manager says - Condition - Poor, Remaining capacity - 80% - is it possible?!? Is it possible the battery goes down for one night?!? I tried other battery and the laptop works fine. I wrote several topics but didn't find any solution for my problem. Do I have to buy a new battery or it's possible the problem to be sofware?! And the last - sorry for my english. Thank you in advance

Yes. I've had it happen to me. It wasn't overnight but a few days after I'd last used it. As I understand it the problem arises because one or more cells inside the battery short out. This can't be repaired. There are places that claim they can "refurbish" notebook batteries but I've never heard of any with consistently good results.
But look at it another way. You have a "T60 with original battery." These batteries are under a 1-year warranty even when the notebook itself came with a 3-yr warranty for a good reason. That's because they deteriorate slowly and thus they're considered expendable, like the battery and tires on your car.
Your T60 must now be at least 3 years old. You got good use from your battery. As frustrating as it may be to see the battery die suddenly and for no apparent reason, it really did give you a good run for its money.
