Is it possible to disable built in battery in x240?

Hello,
I was wondering if it possible to deactivate the internal battery in my lenovo x240.
I usually use t laptop every day  for 12h in a row and I am afraid I am messing up with the batteries , continuosly charging and discharching them. I'd like to use the laptop AV powered only , so I can keep it plugged to AV continuosly, without ruining the internal battery. Is it possible?
thanks

  • Disable built-in battery, will it extend its life?

    Hello people,
    I am the owner of a Thinkpad S440. I love its battery life so I want to make efficient use of the battery. When I disable the built-in battery will the battery actually last longer since I don't use it?
    Thanks in advance

  • Is it possible to disable the low battery warning?

    Hi,
    Is it possible to disable the low battery warning that I get at 20% and 10% power remaining on the iPod Touch? I find it annoying that I get the low power messages when I am in the middle of playing a game.
    Thanks

    I don't think you can disable it. It'd probably be more annoying to have your iPod die while you're making progress in a game though, just a thought.

  • Lenovo S430 - disable built-in battery permanently?

    Hi!
    just got my S430 this week. i love it except the built in battery.
    i use it at home mostly so its plugged into the ac all the time. 
    I wonder if I could disable the battery so it won't be charging 24/7. dont really want that as it'll kill the battery.
    or are there any set up in the power management to take the load off the battery?
    thx in advance~
    Solved!
    Go to Solution.

    won't be possible, unless you physically disconnect the battery. Also with the Lenovo Thinkvantage battery charger, you can set the charge threshold rate, so the battery won't charge all the time even if you are connected to the AC (the biggest benefits of Lenovo ThinkPad machine).

  • "Built In " battery ... what is the best way to deal with it ?

    Hi ... I just bought this laptop envy6-1100se with a built in battery and I actually heard alot of diffrent opinions about the best way to deal with the battery and charging and I don't know what to trust to make my batterylife the longest   so hope u can help me with that .. I want to know also if there is any damage to the battery if I kept it plugged to Ac Power even after it's totally charged ... ??

    You want to minimize the number of charge/discharge cycles so yes it is actually a real good idea to have it plugged in whenever you can. Just to illustrate, Samsung makes several models with integrated batteries and they actually have a setting in the BIOS where you can choose to cut off charging at 80% battery power. If it never goes above 80%, then discharging and charging below the 80% level never registers as a cycle. The battery has a smart chip that counts cycles. After a certain number, say 500, the battery will no longer work. This is to minimize the fire hazard from older Li-ion batteries. In other words, you trade runtime on a "full" charge for longevity of the battery. You might go from 5 hours to 4 on a single charge but the battery will last 4 years instead of two and a half. The battery can actually be replaced but it is a huge pain. The "Samsung" solution is not available on HP's that I have been able to determine.
    So, as I said there is not much you can do except use AC power as much as possible and treat the battery like your life savings; use it sparingly.
    And I recognize that when it comes to batteries on laptops, it is like a discussion of religion. There is more than one respectable opinion but this is mine.

  • Possibility to disable OSX Lion native full screen support?

    The newly implemented support (in v14.0.1 as far as I can tell)) for native OSX Lion full screen support makes fullscreen pretty useless in a multi monitor setup. With the previous version it was possible to continue using the other monitors for other tasks.
    Is it possible to disable the support in some way to actually have useful fullscreen support again, i.e. the way it worked before v14.0.1? Otherwise such an option is needed in my opinion.

    I've built a simple addon that does just that: reverts the old pre-14 Fullscreen behavior. It isn't yet reviewed, so wouldn't show in searches until approved.
    Here's the direct link: https://addons.mozilla.org/en-us/firefox/addon/old-lion-fullscreen/. Bugreports are welcome!

  • Is it possible to disable the autodimm function, so that the clock can be displayed all the time?

    Is it possible to disable the auto dim function, so that the clock can be displayed all the time?

    At this time it is not possible. Sorry. 
    Being able to do so would dramatically decrease your iPod's battery life between charges.

  • If my iPhone is stolen and the thief shut the phone down, I wouldn't be able to locate it anymore.  Is it possible to disable the possibility to shut down the phone when a passcode lock is set up?

    If my iPhone is stolen and the thief shut the phone down, I wouldn't be able to locate it anymore.
    Is it possible to disable the possibility to shut down the phone when a passcode lock is set up?
    enable prohibition shutdown option, with out a jail break tweek
    Apple should think about this, if not already in the new IOS 7

    No.
    The battery will run out sooner or later anyway, even if you could prevent shutdown.
    iOS 7 includes a feature that prevents anyone wiping and then re-setting up the phone without your AppleID and password.

  • Lumia 800: Is it possible to disable the tactile f...

    How can we disable the vibration when you push the back, home or search button of the Lumia 800?
    Is there a way to do it like e.g. the way to enable the hidden diagnostics? ##___#, where ___ are 3 numbers.
    I don't need this kind of tactile feedback, because the screen already shows the response and I don't like the feeling. It could also save some of the precious but poor battery life. 

    Hey
    I asked Microsoft on this issue, and they say it is up to you to disable the feedback.
    http://answers.microsoft.com/en-us/winphone/forum/wp7-wpdevices/lumia-800-is-it-possible-to-disable-...
    Anyway, can I return my Lumia 800 because of this feature is simply unacceptable. I would rather buy an iPhone.
    But should you provide a solution to disable this feature, then I am a happy customer.

  • W520 & Windows 8 - Is it possible to disable the Caps Lock Key?

    Hello All:
    I have a W520 running the 64 bit Window 8 Pro OS.
    Does anyone know if it is possible to disable the CAPS LOCK key on the ThinkPad keyboard?  I keep hitting this key by mistake (fat fingers, I guess) when using the laptop keyboard, and it is a PITA.
    When I have the W520 docked and I am using an external (Microsoft hardware) keyboard, I can disable the CAPS LOCK key on the external keyboard using Microsoft's keyboard control panel application.  But, this application doesn't appear to support disabling the CAPS LOCK key on the keyboard embedded in the W520.
    All suggestions will be gratefully received.

    W520 (4270 CTO), which replaced a W500 (4062-27U), which replaced a T42P, which replaced an A21P...

    You cant technically disable it, BUT you can go to settings>General>Auto Lock - Never
    The screen will never dim and you wont have to slide to unlock - but keep in mind this will drain the battery much faster since the back light is constantly on.

    Charge the phone for 15 minutes with the Apple charger. Then hold the HOME and SLEEP buttons at the same time until an Apple logo appears.

  • Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?

    Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?
    E.g. Dell allows you to plug the laptop into AC power but prevent battery charging.
    Note: I do not want to physically remove the battery.
    If there isn't an option on Mac OS, is there anything I can download to bypass the battery when I want?

    Thanks for linking me! Wow I had no idea the clock speed would be cut so severely! What a bunch of rubbish, as if the AC won't provide enough power!
    I guess the only solution to my question would be an app which virtually disconnects the battery but tricks the mac into thinking the battery is still connected. I'm just surprised Apple haven't yet started to build prisons for the government - considering how well they lock up their software and hardware!

  • Is it possible to disable multiple logins?

    Is it possible to disable multiple logins by the same user on different computers? I have network hosted user accounts. I need a way to NOT make it possible for user A to go to client Mac A, login and leave himself logged in there then go to client Mac B and login there also. This is creating some unpleasant effects on the server - naturally!
    Any easy way to accomplish this? Perhaps through Profile Manager?
    Thanks!

    Simon,
    Thanks for the reply but I need some elaboration.... "the "Login" preferences for users and groups".... what exactly are we referring to? I don't see such option (or atleast the way it's written), in either Server app or Profile Manager. Are we talking about the same OS X version?
    Thanks.
    P.S. Despite the fact that I have enabled the option in Profile Manager to logout all users on all computers after 30 minutes of inactivity, I have noticed that the iMac clients don't log out the users after the said time...

  • Is it possible to disable the 'edit layout' link on the record detail page

    Is it possible to disable the 'edit layout' link on the record detail page? Not the homepages, I know there is a switch for that, but I thought there was one for the detail pages?
    I want to disable this as I dont want users saving their own layouts, they must stick to the related sections defined in the default layout. The problem is that if they are to have access to certain related lists when an opportunity is of a certain type but NOT other types. If they have saved the layout (using the 'Edit Layout' link), and change the record type, they will see related sections that have been set to 'Not available' in the default layout (ie step 4) for that 'type'.

    Robbo, at this time it not possible to disable the Edit Layout on the record detail page.

  • Is it possible to disable the screen saver for a certain app?

    Is it possible to disable the screen saver just while a certain application is running?
    The app seems to crash when the screen saver comes on.
    Just so you know, application I'm using is Hogwasher; a newsgroup reader.

    Not really. Just disable it manually when you run that application. Then, send off a bug report to the app's developer and tell him to update it for the latest Tiger. Alternatively, use another newsgroup reader.
