How to calibrate 3000 n100 battery?

Does anyone know the process to calibrate the battery on a 3000 n100? My battery jumps to 0% and beeps but i am still able to run the computer for a while. Those beeps drive me crazy.

Hi there...
I am a retired IBM/Lenovo engineer specialising in the C-series and dead batteries are not unusual! Let's get some things straight first?
1) We built most of the Lenovo/ThinkPad series to take specific batteries designed and built for our systems. They have special added function that handshakes with the microcode, BIOS and software to give a wide range of battery information and control.
2) They used to be very expensive (>£60) but lately there are a lot of genuine ones at much lower prices. I bought two on eBay for just £20 only 6 weeks ago?
3) You have every right to use a competitive/alternate battery but no-one in IBM or Lenovo can or will comment on whether they are suitable, will work correctly or will last very long.
4) I CAN say that I have 'tested' several 'alternative' batteries and not a single one worked as I would have hoped! I will say no more since there are many I did not test?
5) I am not sure what the concept of 'conditioning a battery is'? A battery is an object that holds a charge. Over time its ability to hold a charge reduces to some minimum close to zero? Some batteries 'die' much more quickly than others. Other last much longer of course.
6) Many die because they have been discharged for a considerable time or they have been shorted out in some way and done an irreparable damage?
7) If you have one that ONLY displays 'zero' this is can be because a) It is as dead as the John Cleese and Michael Palin parrot!! b) It has no function that the PC microcode/BIOS can measure c) There is a fault in the PC base code and it can no longer measure the battery.
8) Let us be 'Nerd Sherlock' for a while? My suggestions are a) Try the battery in another C100 that you KNOW shows good charge? b) Borrow a battery from another C100? c) Buy a new battery and know that this is good! (Make sure it IS NEW! I reported a seller to eBay that sold C100 batteries as 'new' and were clearly 'used'. You can usually tell an old one because it does not come in the original box and the gold contacts show signs of wear. Even installing the battery a single time causes marks on the contacts?)
9) Finally.... Ensure the battery is genuine! On the rear it will have the Lenovo logo top-left, the turquoise Li-ion label bottom-right and a 22-digit barcode? The ASM should be 92P1179 with a FRU of 92P1180. I have never found a non-Lenovo battery with the turquoise label?
10) Best suggestion? Dump your current one and buy a new Lenovo one? You will be surprised at how much additional info you get once you install the Lenovo Power Management Driver from http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/60pm07ww.exe
Good luck?

How to calibrate an iPhone battery?

Hi, I took my iphone 4s to the genius bar at apple store today. Despite having terrible battery problems they told me to wait for ios 5.1 and to calibrate my iphone battery, I was also told that replacing the phone would not be a solution as it is a software based issue.
So I have been browsing the web on how to calibrate an iphone 4s battery and have found answers but they all seem different. Answers I discovered were:
1.
We must let the iPhone runs the entire burden of the battery, i.e. use it until it shuts down for lack of battery.
After the iPhone battery has run out, we let it sit for about 6 to 8 hours.
After this time because we can connect it to boot to load, this process should be left between 6 to 8 hours. (While it may use its load without disconnecting from the mains.)
Once the load, you can enjoy your iPhone newly calibrated.
2.
"First, plug your device into a charger and let it charge fully – leave it charging for another hour or two after its fully charged. Then, remove from the charging source and use your device like normal. Do not plug it into a charging source, but use it until the device decides to power itself off due to low battery. When that happens, plug in your device into a charging source and let it charge fully. During this time, it is completely safe to use your device."
Im still not sure how to calibrate an iphone battery.
Can anyone please tell me the correct method?

Calibrate iPhone Battery:
Use the iPhone until it it shuts OFF itself, due to Low Battery. Then Charge it back up without interruption, like unplugging it, to full charge 100%. Then before or after you do this, Reset iPhone, hold both home and power buttons until the iPhone restarts itself, ignore the "slide to power off slider", let the iPhone restart itself.

How to calibrate my iPad battery gauge?

I heard that draining iPad battery to 0% is harmful to battery.So how I calibrate my battery gauge without fully discharging it?
I hope somebody will give me a clear answer to this.

When the guage says 0% the battery still holds a safe charge. The guage is only an indication, and the phone (being smart) ensures that the battery charge can get neither damagingly low or overcharged.
Once a month or so, run the iPad, ignoring battery warnings, until it powers itself down. Then plug it into its charger and charge it up to 100%. That's it. The battery couldn't care less about this procedure, but it will as you say calibrate the gauge.

3000 N100 battery problem..

Yes.. its the same problem as described here http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-69671
Even so I have "only" been having this problem for about 4 months, so even if I had responded immediately I would have been too late for the above support solution which ended OCT 2008!
In the summer of 2008, my Lenovo 3000 N100 (bought in April 2007) came back from service with a new battery (the old one had died too!). The battery has FRU part no. 92P1186, so is exactly one of the faulty batteries.
My question is: is it reasonable, that I got this battery as a replacement from an official lenovo service center in JULY 2008 WHEN THE PROBLEM WAS FULLY KNOWN??
I think not. Whether they were not reading the bulletins, or trying alternative ways of "recycling" the battery, it is their mistake, and I got a battery that was, if not without value, then practically unsellable.
Am I out of luck?
Kim Borch

I have just been searching Google about a fault I have found with my laptop and came across this site, thankfully...
I bought the N100 just over a year ago, about 8 months into having the laptop I found that the battery seemed to just stop charging. So I took it upon myself just to buy a band new Lenovo Battery as I need the laptop for my university course. Just recently this new battery that I have bought has done exactly the same thing and it’s a little annoying.
After reading what people other people have posted on here I thought I would sign up and see if anyone can help me resolve this problem now that I have had two n100 batteries to exactly the same thing to me.
Any assistance would be greatly appreciated.
Regards,
Ben
P.S. the only reason i have created a new post is the ones relating to my problem seem to be locked.

3000 n100 battery freeze

My Lenovo battery missed the recall as it was only posted on the Lenovo website and not sent to me by the Lenovo messaging system. The original battery has now failed completely. I have purchased a non-lenovo 9 cell replacement. The battery charges and runs the laptop perfectly, but the machine will not start up on the battery with Vista Business. It freezes at the "horizontal bars" display. Attempting to start in safe mode stops at the CRCDISK.SYS install. Can anyone offer advice please?

When I had the no charging problem on mine, resetting bios battery fixed it.
If you have already tried that, there may be some other hardware problem.
I am using a aftermarket battery, works fine. I also have a "genuine" replacement
battery, works fine.

N100 Battery won't charge!

Hello Mark,
My N100 battery refuses to charge. My warranty curse has done it's job perfect. Things die down on me as soon as the warranty period expires. I initially thought that since i didn't use the machine for 3 days continuosly, probably the battery might have been over discharged. Followed the lenovo advice to switch off the machine and leave it on charge for 24 Hrs; but no results. Tried reconditioning etc. Can u please help.

How Do I Downgrade From Windows Vista To XP On A 3000 N100 Series Notebook?

Hello. Here is the problem. I have Windows Vista Pre-loaded on my 3000 N100 Notebook, absolutely dislike this operating system and want to erase and load Windows XP. From reading other forum messages I have learned several things.
1) The install disk On Windows XP Home & Professional will not recognize Sata Hard Drives, when it reaches the point of loading where it looks for the hard drive it "BOMBS OUT" with error messages.
Several options are open .............
1) Log into the BIOS, locate the SATA option, and change to compatibility mode.
2) Have a USB external floppy connected with a Sata Driver on it and when installing Windows XP press the "F6" button when Windows asks for any external drivers you want to load.
Here is the problem with the 3000 N100 Notebook series..........
1)There is "NO SATA OPTION" in the BIOS of the 3000 N100 series notebooks to choose. In this model Lenovo stripped the BIOS down to the bare essentials.......and I Do Mean.... "BARE". The latest BIOS upgrade also has no Sata option. Why they did not offer at least this choice of downgrading to XP is beyond me. LENOVO..... I'm not impressed with your notebook. As usual.... Microsoft has all vendors jumping to their tune..... Nothing but "VISTA" at this point in time. What if you hate it??????
2) I have hunted all over the Lenovo Web Site for a "SATA DRIVER" that would work with a 3000 N100 Notebook, no such critter exists. LENOVO..... Couldn't you have at least offered this???? I'M NOT IMPRESSED.
Has anyone been able to downgrade to Windows XP successfully on a 3000 N100 Series Notebook??? How Did You Do It?? Has Anyone Located A "SATA DRIVER" That Works??? IF So, Please Explain To Me Step-By-Step How I Can Get Rid of Vista and Load XP.
Help........Help.......Help........Help......Help!!!!!!!!!!!
Regards

Hello Himleung. Thank you for answering this message. Where did you find a "Sata Hard Drive Driver" that works?? Perhaps you could pass that along to this message forum in case someone else that has a 3000 N100 (may also work with the N200 series) Notebook wants to downgrade from Vista to Windows XP.
This is what baffles me to no end. The Lenovo web site has every driver you need to load Windows XP on the notebook.....**EXCEPT**..... the Sata HD Driver......**OR**...... the ability in BIOS to change to "compatability mode". Duh!!!..... whats wrong with this story. I have never seen such a weak BIOS as the one in the 3000 N100. If I had known this I probably would have gone to another brand. They should have advertised this notebook as...... "Non-Geek Compatible".
Not knowing exactly how you could forward the driver to me I did the following....... I created a new Web email location that you could use to send the driver as an email attachment. The address is....... [email protected] This address will exist just long enough to obtain the driver..... and then......"Hasta-La-Vista" baby......end of story......as I do not want to be bombarded with ads, trash, or perhaps a virus of some sort..... although.....I'm SURE we have GREAT PEOPLE on this message center.
I'm not familiar with the "NLITE" program you mentioned. Again....perhaps you could mention where I can get it and what I need to do to set the program up to run the driver.
Thanks again, Himleung.

Satellite L755-S5153 How to calibrate bew battery?

No matter how long I charge my new battery, the max charge it will report is 99%. Will calibrating fix this problem? And how do I calibrate a new battery?
Thanks for the help!

TheJake
This is not a calibration problem.
Newer windows versions keep the charging % at 99 for reducing Li battery stress (oh, yes, they do) and give you a longer usefeul life.

How do you calibrate the iPad battery?

How do you calibrate the iPad battery and is it necessary to discharge battery 100%. I have the 3 rd generation iPad, it has been almost a year since I purchased it and the battery when fully charged reads 100%. Recently, I visited my local Jump Plus store and the staff said I should drain the batteries on my iPad & iPhone completely until they are dead and recharge once a month. Is this accurate? It is my understanding that you should not drain the batteries completely? Also, is that the same as calibrating the battery?

For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Lenovo 3000 N100 0768 DKU Battery problem

Lenovo 3000 N100 0768 DKU Laptop has battery issues. The battery shows 75% & total battery power remaining @ 76%.
The battery charge does not change when connected to the system with the AC adapter. The system will only function with the AC adapter attached. The system will not function on battery alone.
Is there some type of battery re-calibration available? My husband checked the battery with a meter that shows that it still does have power. The battery is a Sony LION; the original one purchased with the computer.
Thanks in advance for any suggestions offered!

Lenovo 3000 N100 - Stays on just for a very short time

I have a Lenovo 3000 N100, Model Type 0689-29U
Will power up but only stay on for a short time (less than two minutes usually) before it shuts down without any errors. Does not stay on long enough to run hardware diagnostics.
Have replaced the following items so far:
1) Main System Board (motherboard)
2) Both Memory Modules
3) Power Adapter (power brick)
4) Hard Drive
5) Battery
Still the same results. I am not thinking that the CPU may be either bad and/or it is heating up. I am not sure how the fan on this unit is supposed to behave. In other words, I am not sure if it is supposed to be on all the time or not. When I first power the system up, the fan comes on just for a few seconds then goes off and never comes back on again. I assume that is because this unit's fan is supposed to come on only when needed although not sure.
If anyone has any ideas and/or any feedback on anything I have written above, I would greatly appreciate your input.
Thank you.

remove the battery and plug the ac power, and check if issue persists.

How do I prolongue the battery life of my macbook pro?

Doubled Fingerprint Interface on 3000 N100

I recently used System Update to update the fingerprint software on my 3000 N100 running Vista Business, SP1. The version of the fingerprint software now installed says it is 1.1.0.19 (fron its "about").
The new version seems to load faster and work more reliably, but I now have *two* fingerprint reader interfaces showing up on the login screen:
- The new one, with a large centered "finterprint login" icon
- The previous one, the interface that was there before the update. This is a smaller box near the top of the screen, below a wider drop-down. This one repeatedly appears, disappears, re-appears, etc., cycling every every few seconds.
How can I get rid of the previous one? Its on/off cycling strongly interferes with using non-fingerprint (password) login, since whenever it reappears it steals the focus, grabbing the cursor out of the password entry area.

Download the HP file from here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-56164-1&lc=en&cc=us&lang=en...
You'll need to extract the files using WinRAR (WinZip will not work); you'll need to download and install WinRar (www.rarlabs.com), then right-mouse on the file you downloaded in step 1, select "extract to" and choose a destination.
Go to Device Manager, select the Authentec AES2501A, choose "update driver", and browse to the location you extracted the files to in step 2.
Voila! Do not run the install file, as it's designed for HP/Compaq computers, of course, so I don't know what it would do. However, I now have Vista SP1 installed and all apears to be running normally.

How can I use the battery and let it be perfectly healthy?

Hello everybody!
I love this forum because everyone is a great helpful person.. .. However, I'd like to ask you couple things about the MacBook battery...
I know that now the battery has been improved, it leasts longer and it can support 1000 charging cycles.
(Right now I'm performing the battery calibration)
I'd like to know how can I use the battery and let it be perfectly healthy.
For instance,
1) If I connect the laptop to the MagSafe and let it charge, when should I remove the plug from the Mac and when should I put it in charge? I don't wanna continously waste cycles and let my battery die too soon (it's too young to die! :-D ) .. I use it mainly at home connected to the MagSafe: someone tell that even if you leave the MagSafe connected after the mac has been charged it stops charging (I can see this), and others say that is not a good thing to let the mac connected to the plug for a long time... with the old model I used to disconnect the battery from the mac so I didn't have these problems but with the new one it's a long procedure...
2) I usually use to calibrate the battery once a month... Is it a good thing?
Thanks!
Andrea

How to restart ipad once battery has run down

how to restart ipad once battery has run down

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
