  1. don't post your email in a public forum or you will get spammed.

    DOS requires a dos boot disk, however you already ran the flash in windows so you have no reason to do that.

    The battery calibration is probably off or the battery is bad. There should be an option in the BIOS to run a battery calibration cycle.
  2. hi unksol,

    pls give me a valid answer which would be helpful and i will try it at that same time it should start charging normally like how i had purchased my laptop and it was charging normally thanks reply soon? acer aspire 5741g .

    pls some one help me my laptop doesnt charge 100%. pls give me a good answer for this question which could help me out charging normally like before thanks all my friends.
  3. That is a valid answer. Laptop batteries track their charge cycles. They also decay over time. its entirely possible for it to be fully charged but report being at 93%. This is what the battery conditioning is for in the BIOS. It runs the battery through cycles to recalibrate where the full and empty (0-100%) points are. If you refuse to try to fix your issue that is your choice
