Is there a software that is associated with my sonny battery that will make it charge again


Hi there,

If you plug in your AC adapter to your laptop to charge the battery and get the "plugged in, not charging" message then try the following solution:

  • Disconnect AC adapter
  • Shutdown laptop
  • Remove laptop battery
  • Connect AC adapter
  • Power on laptop
  • Click the Startup Menu
  • Type Device and select Device Manager
  • Under the Batteries category, right-click Microsoft ACPI Compliant Control Method Battery and select Uninstall.
  • Shutdown laptop
  • Disconnect AC adapter
  • Insert laptop battery
  • Connect AC adapter
  • Power on laptop

    If you follow these steps and find that your laptop still does not charge then consider replacing the laptop battery itself.

    Hope to have been of assistance,
    Thanks.

    AC Adapter issues Q & A.


    <p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small "camera flash charging" sound, stabilizing at 19v. When charging, it repeatedly makes the "charging sound" Faulty AC adaptor? Or Faulty battery? Or Both?<br /> <p><b>A. </b>First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It's either broken or loose. It's a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.<br /> <p>It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord. If it does, replace the adapter.<br /> <p>Second problem: The battery will discharge from 100% to 90% and then jump to 0%. It sounds like a bad battery.<br /> <p><b>Battery charging light is on even when power adapter is unplugged and laptop is stitched off</b><br /> <p><b>Q.</b>The yellow light for battery charging does not go even after switching the laptop off and power jack is disconnected.

    You may have a DC connector problem:

    Symptoms of a broken power jack
    1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
    2. Battery will not charge in the laptop.
    3. Laptop runs fine off a charged battery.
    4. With the AC Adapter connected the laptop appears to be dead.
    No power LED or battery charge LED activity.
    5. Laptop randomly powers off without any warning.

    If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

    My Sony Vaio battery light remains orange


    If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all.
    OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time.
    If the battery drops to an unacceptable charge level then the battery needs to be replaced.

    Acer aspire laptop won't charge


    Hi,
    First of all you have to determine whether it's the battery, charger or the laptop itself.
    Remove the battery and boot the laptop on AC power only, if the laptop boots up you can rule out the charger and the laptop, you may need a new battery if that is the case.

    Battery charging status remains constant (not increasing)


    I've have seen a number of different batteries do this, and I recommend what is called 're-conditioning the batteries. Do this by running the battery completely down to 0%. Then do a complete re-charge of the battery to 100% (if possible). If it charges to 100%, run it completely to 0% again and then recharge it. If it does not charge to 100%, then you may have a faulty or old battery which will need to be replaced. The AC adaptor and battery have circuitry in them and might be retaining incorrect info in them. They can be reset by unplugging them for a few minutes and then plugging them back in. There might be a specific sequence of what to unplug and when, in order to reset this circuitry. Try a couple of them. (ie. Battery, AC adaptor in to battery, AC adaptor into the wall, etc.)

    Let me know what happens. Binary Bob
