Set a custom charge threshold to start charging only when the battery is at 10% or 15%. In practice this will power the battery charger only when it's absolutely necessary. In the meantime you'll see the remaining battery charge drop gradually, perhaps by 1% every few days. This is normal self-discharge.

  • How to Disable battery charging Function?

    Hi;
    I have a question about charging funtion of my "HP Compaq Business Notebook, 6720s":
    How can I disable "battery charging" function in windows 7? Is there any "advanced setting change" or "software"  that while battery is in its slot, stop my notebook from charging its battery?
    Thanks

    After some days trying many methods, yet I haven't find a solution to my problem. Then I ask is there  any one
    knows which software should I download for HP Compaq Power Management (similar to the software that Huffer
    mentioned, but that was for Lenovo) or which registery or BIOS change should I do , so that I can manually disable
    charging function of laptop, or at least put a starting level that up to that level, laptop won't start
    autolatically to charge battery, because in this manner once that my Battery reaches to below 100%, instantly begin
    to be charged & it would decrease its life time. Please consider that because of my power cable is to some damaged, sometimes it suddenly disrubt & cause my laptop abruptly shut down, then necessarily the battery would always be connected tob prevent this suddent effect.
    If any one could help me, I would appreciate him a lot.
    Regards

    How to disable auto charge of iPhone via PC?

    I'm thinking you may have the concern of not overcharging or messing with charge cycles of your phone, but according to apple the Li-ion batteries in iDevices work this way for example
    -Your phone has 50% battery left, you charge it
    -after using again, you're back with 50 and charging it till full once again makes it 1 charge cycle
    Doesn't work like nickel batteries.
    Here's the article:

  • How to disable auto charge via usb?

    So the question is as that: is it possible to disable auto charge when plugging iphone to the macbook in order to save the battery of macbook.
    Tried everything but couldn't find any solution. Moreover it seems like I was questioned something like "permit to charge iPhone via usb?" when I first plugged it to the Mac, but I'm not sure
    Thanks alot for any help!!

    I am reasonably sure since there are no hidden menus to enable this.

  • How to change battery charge settings in Windows 8

    On my previous Thinkpads I could change the battery charging settings in Lenovo Power Manager. (things like minimum charging threshold, etc). Now in Windows 8 Lenovo seems to have abandonded the Power Manager, but there is still a power manager driver. Is it still possable to change the battery charging settings?

    Check out this Knowledgebase Article from buddinggeek.
    I hope it is what you were looking for!
    Thank you for being a part of the Lenovo Family,

  • How to disable battery protection mode on Linux Mint

    I did a frest install of Linux Mint on my newly bought U310, everything went well, except -
    I turned on battery protection mode in windows so that the battery never charges above 60% to preserve battery life span,
    But now on linux mint, the charge on the battery still caps at 60% and there are no options to disable it.
    There doesn't seem to be lenovo drivers for linux either.
    Any help is appreciated.

  • How is the battery charging of your new aluminium Macbook

    Hello Users,
    I wanted to know what exactly is your experience about the new Macbook 2.0 aluminium charging like? Meaning, I read in forums, you tube comments that the macbook takes hours to charge in some case 5 hours. IS this true? Or are these one of cases of bad batteries?
    Cheers,

    Yours is a different question from the original poster's. You should probably start a new thread in the Batteries and Power forum:
    http://discussions.apple.com/forum.jspa?forumID=1289
    But when you do, could you explain what you mean when you say your MacBook was "off at the plug"? Does that mean the green LED was not lit where your MagSafe plugs in to the computer, or that upi unplugged your computer overnight? If your computer was sleeping while unplugged, it would not be surprising for it to consume some battery power.

  • Any way to stop battery charging at under 100%?

    Research has shown that a battery kept at 40% charge will retain 96% of capacity after 1 year (at 25 degrees C), while a battery kept at 100% charge will retain only 80% of capacity after the same period of time.
    Is there any way to control the maximum charge level, so that the battery stops charging after a certain point (say, 40%, or 75%). Thanks.

    Like the above poster said, you can't control how long the battery charges--unless you unplug the cord yourself.
    I would like to mention something for you. My battery is 11 months old, and has maintained 98% of its original capacity. Within the next 4 weeks, it will hit the one-year mark, and I don't anticipate it failing on me before it has reached the typical lifespan of ~300 charge cycles. I wouldn't be surprised if it hangs on for another 100! It currently has 264 to its credit. I think my battery is doing pretty well--and I run off it for a few hours nearly ever day
    Of course that's an expected outcome with most lithium rechargeable batteries. However - they do have their drawbacks including an inherent loss of total capacity from the aging process.
    The best thing for your battery is to USE it, even if you're sitting at your desk much of the time. Unhook the power charger for 30 minutes, or an hour, then reattach it. If it doesn't seem to be working properly, calibrate it.
    It all depends. Using a battery and charging it to near maximum by definition cut capacity because of some loss of the electrolyte solvent when it gets vented. In NiMH batteries, the solvent is water. It's a non-water solvent for lithium rechargeables. If it's not vented, it could potentially explode. Using a battery every day will result in noticeable loss of capacity. There's a balance to overuse and underuse of a lithium rechargeable battery. Apple recommends that a battery be partially drained at least once a month. My MacBook is set up with an iCal reminder to use battery power once a month.
    The 40% you mentioned from the article is something I've heard before, but I believe it was mentioned in relation to storing your computer for an extended period of time(ie several weeks). If you wanted your battery to be healthy when you returned, you wanted to store it after you'd partially discharged the battery.
    I've brought up the extreme case of first generation hybrid car batteries. They employ a different strategy for charging that takes advantage of an always present charging source (the internal combustion engine and generator). They take advantage of the extreme case where the battery is intentionally kept between 40-65% of charge nearly all of the time. Going a little bit under or over this isn't a big deal. This keeps it from the extremes of near max charge and near min charge; both tend to reduce battery capacity for different reasons. The electrical output is only a supplementary power source used during peak demand periods. I've heard of some original batteries from Toyota Prius taxis that have survived 400K miles of service; that probably meant 100,000-200,000 of the shallow charge-discharge cycles. The fact that only a small range is needed means that they can continue this use for a long time. It probably would have been noticeably degraded after maybe 1000-2000 20-100% deep discharge cycles. The total amount of energy drawn over the lifespan is many times with the small discharges compared to deep discharges. You're typically using 25% of the charge hundreds of thousands of times rather than 80% of the charge a few thousand times.

  • "mouse battery low" message in gnome. how to disable it.

    About two weeks I get this message.
    remaining 14.3% of the battery, the mouse ))))
    I can charge the batteries in the mouse, or whether they are used up. all the same - 14.3%)))
    Perhaps this is a very important message, but it appears every minute, and very annoying me
    Tried to look in the documentation of Gnome, how to disable this message, but did not find.
    Maybe do somebody know how to disable that great notification?

    I saw that topic
    run gconf-editor
    go to apps > gnome-power-manager>notify>low power <off>
    it doesn't help.
    Although that hive implicitly refers to the level of battery power mouse.
    There is nothing that somehow say obout battery in the one.

  • How to disable CHARGES tab in Find Sevice Requests(CSXSRISR.fmb / CSXSRISV)

    could any one please let me know how to disable CHARGES tab in Find Sevice Requests ( CSXSRISR.fmb, but funtion registered is CSXSRISV).
    Actually when i access the "Create Service Requests" menu option, the form comes up with a the three TABS (Charges , Work Orders & Maint Req) visible but disabled. But when i access the same from "Find Service Request" menu option, i get the Charges TAB enabled but not the other two... so i would need to visibilly disable the CHARGES TAB like the other two tabs.
    I checked the subfunctions but i could not find any.... i could only find Update Charge and Create Charge options but not the Visible option.

    Hi...
    The Charge Tab in SR form gets enabled only after SR No. Generation.
    So initially when you open the Service Request form the Charges Tab will be visible but disabled, & once the SR number is generated the same gets enabled.

  • How does battery charge work ThinkPad T430s

    I recently bought a Lenovo ThinkPad T430s 2356-LRG and was wondering how the charge technology worked. I have searched around and looked in the manual but I couldn't find a good answer.
    My questions is that I use the notebook alot on AC power. And often for extended periods of mid to heavy load. I run Linux and have setup ChargeThreshold. It stops charge at 95% and begins again at 45%.
    But when I keep the AC power on, and if the battery has 80% it does not move up or down as expected. Because it must drop lower than 45%.
    Will the power then go straight to the machine and bypass the battery? Because the Battery-LED on the back is turned off. Or will it go via the battery and produce charge cycles on the battery?
    So let's say the battery is bypassed will it then be fine to keep it on AC and active for a period of many days with heavy load but monitor the temp of the battery. I know heat kills it.
    I could also buy an 95W power adapter and remove the battery completely from the machine when I have it at my desk for an extended period of time.

    Hey there MikalD and welcome to the forums!
    What you are experiencing is as per normal. These charge thresholds are determined in your power manager, there is a nifty Knowledgebase Article about this.
    First, open up the ThinkVantage Power Manager. Click on the battery tab, and then Battery Maintenance. This will open a window where you will be able to change and set your charging thresholds to your desired preferences.
    Additionally, here are links that can give some insight and advice of how to increase the longevity of battery life.

  • HT4060 I have my iPad plugged into the wall, how come its not charging the battery?

    How come my battery is not charging even though the iPad is plugged in?

    The possible reasons could be....
    1. Bad connector cable
    2. Faulty power adapter/charger
    3. Problem with the wall socket
    4. Faulty dock connector opening
    5. Something impeding the charge getting through - debris in the connector end of the iPad
    6. Faulty iPad/corrupt software
    Try another cable, another power adapter, another wall socket, and go from there. Nobody can just guess what the reason is, start eliminating some of the possible causes and go from there.

  • HT3053 How long should I charged new battery in MacBook pro?

    How long should I charged new battery in MacBook pro?

    You can leave it plugged in all the time if you wish.
    Once your Macbook is fully charged, it stops charging.
    You can see this if you click on your apple logo, about this mac, more info, system report, power.
    In any event, it is also a good idea to use your Macbook under it's own power to keep the battery in optimal condition.
    As much as possible, try not to fully discharge your battery.  It could do more harm than good to your Macbook.
    Good luck and enjoy your macbook
