9 cell battery performanc​e on Thinkpad T410

I have just bought new ThinkPad T410 with 9 Cell Lithium-Ion
Power 94 Watts/55++. This battery is advivertised to run for 18 hours, but to my laptop it runs for about 6 hours on a single charge for normal use. what is wrong with my loptop because it has failed to meet my expectationns of all day Computing on a single charge. 
this laptop is has 4gb of ram and windows 7 professional 64 bits and is about one week since I bought it. any advice to increase battery performance

the 18 hrs figure require another 9 cells battery slice. Although it is up to, and the manufacturer's battery figure are at most time too idealised.

  • Do all T410s ThinkPads come with a 6-cell battery that sticks out ?

    I remember reading somewhere that the 6-cell battery sticks out the side of the T410s making it awkward in appearance and in handling.  Is that still true?  If so, do they have something like a 4-cell that stays flush with the chassis?  I could not find this as an option during the online configuration nor is it listed as an an available accessory for the T410s.

    My T410 has a 4-cell and is flush.  I think it was the default on the configurator I used, or at least it was an obvious option, because I didn't have to search for it.  I don't know if the 6-cell sticks out or not.
    I ordered using the "employee" (retired) system in the US at the end of March.  Don't know if that is relevant or not.  I'd try calling sales if you decide you want one.
    Good luck,

  • Thinkpad T510 6-Cell vs. 9-Cell Battery

    For a Thinkpad T510 with 128gb SSD, i5-540 processor, nvidia 3100m 512 mb discrete graphics, and 4 gb RAM, does a 6-cell battery cut it? How much time should I expect with a 6-cell and with a 9-cell battery? Also, by how much does the 9-cell protrude past the back of the laptop?

    I have a 6 cell with my T510 and I'd say for normal usage (browsing internet on youtube, watching some news clips, reading email, surfing the net and stuff) the usual time I get on performance setting is around 2 hours.  If intend to take this out and use it for a day, 2 hours certainly won't cut it. 

  • (SOLVED) Thinkpad T410 and 3G internet

    This post may reflect my lack of experience with notbooks, but I have a question regarding my brand new Thinkpad T410. I didn't choose the notebook myself, it was given to me through my employer. Naturally all administrator privileges are non-existing, so I have to rely on my company's "technical support" for any changes to the software.
    Now, if I'm not mistaken this computer should be ready for a sim-card and 3G internet connection (That's WWAN, right?). Model is 2522-WTX. Now, in device manager, I cannot find anything regarding a WWAN module, allthough there is a SIM-card slot under the battery.
    I have allready called for my employers support department to help me out, but I know that they just started buying the Lenovo computers, and they don't have that much experience setting them up. So I'm trying to help them out by figuring out what needs to be done. From what I have read so far, installing drivers for this module should activate it. I don't know if the "Access Connection" tool is strictly needed. However, on Lenovo's  drivers download page there are too many choices for driver download:
    1) HUAWEI EM660 Wireless WAN
    2) HUAWEI EM660 Wireless WAN firmware
    3) Leadcore 5730D Wireless WAN
    4) Thinkpad Wireless WAN (UNDP) - Boot Code Update Utility
    5) Thinkpad Wireless WAN (UNDP) - Qualcomm Gobi2000
    Do I need all of them? Some? Which ones? Should I be good to go only with the drivers, or is Access Connection needed (I'm running Windows 7)? Is any SIM-card valid, or are there any ISP-related limits I need to know of (currently my mobile internet provider is Netcom, Norway).
    I hope that some of you are capable of helping me out, thanks in advance!

    Thanks for all answers. To get to the bottom of whether I do have the 3G-card installed, I opened up the hatch underneath the laptop. There it is, as someone said, it is the Qualcomm Gobi2000 card. Antenna wires connected.
    So, I browsed through the device manager again. It seems that I hadn't looked at the right places. I had looked at "Modems" and "Network cards". But in the "Ports (COM and LPT)" category, it is listed as "Qualcomm Gobi 2000 HS-USB QDLoader9204 (COM5). No exclamation point either. When going to properties, the driver date is 12. jan 2010. Driver version 2.0.7.1. Port  settings are: bps: 9600. Databits:8. Parity: None. Stopbits:1. Flow control: None.
    But how do I use it? Fn+F5 doesn't seem to do much (should it?). I can't find any way of accessing it through the regular windows 7 Network and Sharing Center. As I wrote in my first post, I have no administration rights, so installing additional software needs to be done by my company's tech guy. Is there any way I should be able to connect through 3G without eiter 3rd party or Lenovo software? Any BIOS-setting that needs to be altered?
    PS: I also have none of the Lenovo software preinstalled (Lenovo system update, toolbox etc.). This computer is almost completely stripped :-(
    The Qualcomm device on COM5 is the GPS serial interface, the 3G card should be listed under Network Adapters. Once the card is working you should be able to select your provider from inside of access connections to connect.

  • Possible defective X240 3-cell battery. Help me diagnose!

    I bought an X240 about 2 weeks ago and things are running fine.  It came with the large 6-cell battery.  Last week, I purchased a genuine Lenovo 3-cell battery from a third-party reseller.  I plugged it in this morning for the first time, and it seems to be defective.  Please see the screenshots below.
    https://dl.dropboxusercontent.com/u/6625784/battery_error.jpg -- this error message popped up when I first booted the computer after putting the new battery in the computer.
    https://dl.dropboxusercontent.com/u/6625784/battery_error2.jpg -- this is what the Lenovo diagnostics software shows.
    https://dl.dropboxusercontent.com/u/6625784/battery_error3.jpg -- this is what the Windows 8.1 system tray icon shows.
    And here are two pictures of the battery itself:  https://dl.dropboxusercontent.com/u/6625784/battery1.jpg  https://dl.dropboxusercontent.com/u/6625784/battery2.jpg  --- It is FRU 45N1125, which is the correct model for the ThinkPad X240, as far as I can tell.
    I have removed and re-inserted the battery several times, so I am confident that the battery is installed correctly.  I also shut the computer down and plugged the power cord in for about an hour to see if it would charge while the computer was off, and it did not--it remained at 0% even after charging for an hour.
    This appears to me to be a defective battery, but if anybody has any other ideas, please share them and I will test.  Thank you!

    If you let the internal battery charge to 100%, will the removable battery start to charge at that point?
    I know you said you let it charge for an hour but your screenshot showed the internal battery at 54% and charging.  ThinkPad can only charge one battery at a time, so the removable battery won't charge until the internal battery stops charging.  
    If the internal battery gets to 100% and still the removable battery won't take a charge, then it is very likely defective.

  • T450s: missing 6-cell battery option in the configurat​or

    Dear all,
    now that the hardware trackpoints buttons are back it's time to buy a new thinkpad!
    I'm configuring a T450s on shop.lenovo.com, but I noticed that the 6-cell battery option is missing. The only option that appears is:
    ThinkPad Battery 3 cell Li-Polymer (23.2Whr) Rear
    but I'd like to have the big one.
    What am I missing?
    Thanks!

    Same battery (0C52862) as T440, T440s, T450, available here.
    There's a big bulge on the bottom for the additional capacity.
    UPDATE: ThinkPad Battery 68+ (6 cell) is available during checkout in the Accessories section.
    Hope that helps,

    I didn't realize until after the purchase that the ultrabay battery doesn't exist for the T410, which sucks. I do like the layout of the keyboard, speakers, special buttons, and fingerprint scanner better on the T410. The keyboard currently has a flaw that another thread points out. the biggest complaint on my T410 (other than the keyboard issue) is the thickness.  Anyway, now these T Thinkpads are fat beasts....and I just have to live with it....or you can pay more for less performance and hard drive storage on the T410s if you want to go back to the thinness. 
    About the ultra-bay battery issue for anyone whom is considering a T410 and needs the ultra-bay battery: consider up-sizing slightly to a T510, since it does support an ultra-bay battery.
    About the keyboard issue: Lenovo released a firmware update to fix this a few days ago and it should no longer be an issue
    About the thickness and weight: it's funny, I guess it's all a matter of perspective.  My previous laptop was a 3.3 year old Toshiba Qosmio G30, with a 17" 16:10 screen, and it's noticeably much larger in all dimensions and at least 1.5x the weight of my T510 (which is larger and heavier than your T410!).  I was literally shocked at how compact and light my T510 is when I unpacked it, and I'm still impressed with its size and weight vs performance.  No regrets for me in that category.  I just thought I'd throw a bit of the opposite perspective out there for other potential buyers.  Now if only they'd release the keyboard bios fix for my T510....

    Spearoid,
    I also have a T400 and have upgrading to the T410 for the newer processor and the new keyboard.  However, I heard that the release for the ultrabay was UNDER the Thinkpad on the bottom side, vs. on the side.  Is this true?
    Yes this is true.  The slider to release the item in the bay is on the underside of the laptop.  Still trying to figure out why this would be a big issue for anyone, but maybe that's just me.  I've never had a ThinkPad before (nor any laptop with an ultra-bay-like feature) so maybe I just don't realize what I'm missing.

  • S12 first impressions - and 3-cell battery question

    Hello all,
    I received my Lenovo S12 yesterday - it is replacing a 5 year old Dell 700m.  
    I didn't even boot Windows, but instead directly installed Ubuntu 9.04.  So far everything is working great!
    My only complaint so far is, of course, the lack of trackpoint.  I know it is an IdeaPad, but I still don't understand why Lenovo doesn't put trackpoint on their Netbooks! It would be a major differentiator in a competitive market.
    I really, really want to get a 3-cell battery.  The 6-cell will be great for travelling, but around the house, I would prefer it to be lighter/slimmer.
    I can't find 3 cell black batteries for the S series ANYWHERE.  Is this just a temporary situation?  Anyone want to sell me theirs?

    [EDIT] I found this battery:
    3-Cell???
    Will that work?
    Message Edited by xnappo on 07-11-2009 07:52 AM

    Yea, 3 cell is definitely better for daily use. Can you use S10's 3 cell on S12?
    lol my old dell 600m is still there, alive, but I have replaced the hard drive twice and motherboard once. All covered in the warranty.

  • Power Manager only charges 8-cell battery upto 36%

    This problem is about to drive me insane.
    It's new thinkpad X200 tablet and new 8-cell battery, only having 4 charge-cycle count.
    I've just discoveried this problem when I upgraded to Windows 7 Pro and updated Power manager to V3.05 of my X200 tablet, but since it's on AC power most of time and I've set battery charging only starts when level below 5% and stop at 100%, therefore my battery only being recharged once or twice a week, but whenever it charges from 5%, it will just stop at 36% and display "charging will start when below 5%", so I will have to change the option in "battery maintaince" in Power manager to "alway fully charge" to have the battery 100% charged. But, I don't really want to choose the alway-fully-charge option torepeatly recharge the battery at near 100% since I have only a few occasion during the day where I need to rely solely on the battery, which only consume it down to ~90%.
    I'm not sure whether the problem is due to the new version of power manager which regard my 8-cell battery as 4-cell?( logically, then it should stop at 50%, right?).
    The battery once did charge on the ultrabase, but I can't remember if that was the time when the problem started.

  • Lenovo Thinkpad T410 got errors with Fingerprint sensor device! So frustrating!

    I have just bought a new Lenovo Thinkpad T410 2518-FAA from one of main agencies of Lenovo in my country. The new-buy laptop was said to be totally new, i.e. it was not a re-furbished, and I actually checked for manything to confirm the real status of this laptop. However, when I bought it back to my house, a serious problem appeared. At the laptop store, I did not have enough time to check the Fingerprint device, thus I skipped to check it. When I came back home, the Fingerprint sensor error of this new-buy laptop completely drived me crazy!!! I installed the Fingerprint software of Lenovo, but this software continuously reported errors: "Can not enroll users, can not update passport, and can not find fingerprint sensor device." I have tried uninstalled and reinstalled this software many times, and already checked for the latest version of this software, it was Thinkvantage Fingerprint sofware 5.9.3 for Win 7-32 bit. My operation system is Win 7-32 bit. But these errors still appeared again and again. I already checked the status of TouchChip Fingerprint Coprocessor in Biometric Devices, uninstalled then re-installled this device, and it showed that this device was working properly and up-to-date, and I already unchecked the option "Allow the computer to turn off this device to save power", but all of my efforts was in vain!!! These errors still appeared and it drives me crazy! Up to now I had been unable to enroll my fingerprint to set up the fingerprint reader! These 3 errors just kept prompting in front of my eyes! Another problem is that the laptop can transfer files to my Nokia E51 mobile via Bluetooth, but I could not make the reverse transfer for a file from this mobile to laptop! Oh, I am very disappointed about Lenovo now! Inside the manufacture box that carried the laptop, there are just some instruction guides without any installation CD for installing Thinkvantage softwares... I had to go to the website of Lenovo and find a bunch of links of softwares that I tried many times but I still did not know how to donwload... I had to donwload the Thinkvantage Fingerprint software from another website... Please help me, guys! Did you encounter the same problem with me? May you please instruct me how to solve these problems! Thank you a lot!

    hey Moon_Light,
    i would suggest uninstalling all ThinkVantage software, then go to http://support.lenovo.com ; download all drivers for you unit and install.
    at the same time do a bios update as well.
