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.

I am unable to save any BIOS updates. I have tried to update the BIOS to v1.4, only to have the same problem. If I make any changes to the BIOS information, the system will either A) Hang on F10/Save Changes, or B) if it does Re-POST the information, ALL of my changes are lost.

Re: Premature CMOS 2032 Battery Failures

Hi,
I have the problem with the CR2032 batteries dying on alot of 7F2WE 1G5D-OC-LF motherboards from Jetway. Has anyone seen that?
I measured and replaced batteries on the units a week ago. The all read 3.25V to 3.3V. I checked them all today and they were between 1.5V and 2.9V. This is a serious problem for me since the product I make uses this motherboard and depends on the CMOS settings. There seems to be no way for me to garantee that my product will actually work when it gets to the customer
Don

I would suggest you go to Jetway with your problem. This not a general forum and is for MSI products.

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...

CMOS / RTC Battery for Satellite A100-326?

Hi,
I'm after a replacement CMOS/RTC battery for my A100-326
I've got my machine open and located the battery but it has no model number on it.
I have contacted a Toshiba assistance center and they replied that the battery is part of the board and the whole board has to be replaced. However, if I can find the reference for the battery, I have a friend in a computer store that will replace it with a new one.
Any help would be great. Thanks!
Regards
Srgio

Hi
Why you want to replace this
Such battery is reachable
To charge the RTC battery you have to connect the AC adaptor to the notebook.
The main battery should be inserted too and the notebook should run for 20.24 hours.
Anyway, as far as I know its a Lithium Ion RTC battery 3V and 14mAh

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.

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.

Is there a difference between a BR 2032 battery and a CR 2032 battery?

Just bought a refurbished Mac Pro tower circa 2009 and wanted to replace the BR2032 battery but couldn't easily find one. Did find a CR 2032 version. Read online the difference but does it mean anything in the working world? Thanks for any insight.

The DVI-I connectors on computers provide BOTH the standard Digital DVI and, hidden in the pins at the end, a direct Analog VGA output. A cheap adapter will pick it off, and that one is better than the one converted from a Mini DisplayPort. [Conversion form Mini DisplayPort requires a complex ACTIVE adapter with a chip in it.]
