    As the title suggests, I have an Acer Aspire 5740-6378 computer where i am using windows 7. From last day, i am not able to charge it. The status shows 21% charged. I have rebooted the device many times but it doesn't do anything.The device is just two months old. Is there any way to fix this issue?

    Normally,It doesn't happen but some users of Acer has reported this kind of issue. Some of them has fixed this issue by following the below given steps:
    1. Disconnect the AC adapter from your laptop.
    2. Now remove the battery
    3. After that press and hold the power button for 30 seconds and then release the same.Nothing will happen on your screen.
    4. Connect the AC adpater again to your laptop. While doing so,make sure that the AC adpater is plugged in.
    5. Start the computer normally.
    6. Once windows boot,just insert the battery. It will fix your issue.However if you are still getting the same problem then either your battery is faulty or your charger is faulty.

    This is a major issue and a brand new device shouldn't behave this way.

    Check the battery if it is having any physical damage,
    check the ac-adapter , charger of any defect can be found.
    uninstall the battery, from the laptop battery slot, plug in the charger, turn on the power is the computer running, then the adapter is okay, install tye battery and attach the adapter again , turn on the power, is the battery charging? if stii not, consult Acer Authorised Service Center for a solution.

    You need to re-uninstall the battery power management software just follow these steps :

    1) Click start then type device manager in the search box and open device manager.

    2) Expand the batteries category.

    3) Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .

    WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.

    4) Now select Action > Scan for hardware changes .

    Windows will scan your computer and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging.

    Dear guest,

    Since your laptop is new I doubt that the problem will be with the laptop and suspect it more on the adapter.
    You need to do certain steps to identify the responsible component.

    Test1:The output socket..
    1. Just try out the charging of your laptop to a different point in the house or a different place totally.
    2. If it charges then you know that the problem if with the socket.

    Test2:your adaptor.
    1. Try using another adapotor of the similar output.
    2. There is a LED light on your adaptor see if it glows.
    3. If any of the two points hold good then your adaptor is alright.

    Test3:the port in your laptop is faulty.
    1.try charging using a different charger.

    Test4:your battery is not proper.
    1. Connect your adaptor cable to the charging port.
    2. remove the battery.
    3. Switch on the power and turn the laptop on.
    4. If the laptop works then the fault is of the battery.

    Guest, since it is a new laptop it will surely have guarantee. So avail the guarantee within a quick time

    Thank you...
