    Hi,

    I own a Dell XPS L702X laptop. I play a lot of games and do heavy multi-tasking and development work on this laptop so the battery tends to discharge very quickly and this made me very concerned about the battery life.

    I wish to disable the battery charging feature and instead use A/C charging as it does when the battery is removed. But in this case I do not want to remove the battery (because it elevates the laptop and makes it more convenient to use, helps in regulating air inside and prevents heating). I want to keep the battery but simply disable it from charging when it reaches full charge, and switch to A/C power mode.

    Is this possible through any software?

    Any help will be appreciated.

    Thanks,
    Niladri

    Leaving the battery in all the time does minimal, if any, harm. Actually using your machine on the battery will wear it out far more than simply having it plugged in 24/7.

    I'd just charge it to full and disable it in the BIOS

    Not true. My 1st laptop was plugged in for a year literally and the battery would drop from 98% to 10% in 5 minutes.

    Yeah my previous laptop also had this problem (battery unable to hold charge much longer) after using it continually in plugged-in A/C mode with battery enabled. That's why I was looking for something that can disable battery when it's fully charged. Then I can continue working on A/C (without the battery being charged) and then again re-enable when I want to use the battery instead.

    fred2028, I am really scared of using BIOS all the time LOL :p

    My wife's 2-year-old 17-inch Toshiba has been plugged in from day one and can still hold a charge for at least 90 minutes.

    Ok one noobish question: does the laptop primarily work on battery when it's fully charged and on A/C power mode? Or does it work on A/C power instead? I know it's very noobish question, I am relatively new to all this.

    @saturnotaku, so it is OK to play games like that, what do you suggest? Will the HEAT affect the battery?

    When you plug in your laptop it uses power from the wall, not the battery.
