  • The Battery is Bad and has a Bad Cell.  If you discharge it lower than 50 percent it will then never charge higher than that.  Eventually it will not charge at all anymore and will flash orange.

    I do not work for Dell. I too am a user.

  • i discharge my battery on 10% and i recharge. but stoping in 81% :(

  • last night i discharge my battery to 0% and my laptop closed because no more energy in battery.. and i put to charge my battery all night..  today when i wake up i open my laptop and i see that my battery are charged 100% i unplug my cable to verify if my battery charge 100%. And i see my battery is charged 100% so at the moment my battery working normally.  I hope to continue to work fine my battery.

  • It sounds like the calibration was off on the battery.  By draining the battery all the way down, you reset the calibration of the battery.
