  1. Following battery change, battery monitor shows "unknown remaining"


    Following installation of a new battery in my ACER M5-481T-6642 laptop running Win 10 (1903), the battery icon in the task bar has grayed out and displays "Unknown Remaining" when cursor is placed over it. Settings/System/Battery also shows vague/unknown battery condition information. When charger is plugged in, Icon has an "x" in it but does indicate battery is being charged.


    Prior to the battery change battery icon was not grayed out and appeared functional even though the battery was pretty well shot. System OS was the same (unsure about updates) before/after battery change. I have tried Device Manager/Battery/Action/Check for updates with no joy.


    Help

    :)

  2. Battery not detected (Unknown remaining)

    Hi,

    First of all I suggest you to try with a driver remove and reinstall with Device Manager. To do so:

    1. Press WINDOWS + X

    2. Click on "Device Manager"

    3. Click on "Battery"

    4. Right click on the first element on list

    5. Click on "Remove"

    6. Repeat steps 4 and 5 for the second element on list

    7. Click on "Detects Hardware change" (monitor icon)

    Then reboot your system and check if the problem still exists.

    Please tell me if the solution works.

    battery gets completely discharged.

    Battery not detected (Unknown remaining)

    If your battery has some years, it could be that is going to die. If not, you should check the battery plug, it could be a bad connection.

    However, try other two times with :

    1. Press WINDOWS + X

    2. Click on "Device Manager"

    3. Click on "Battery"

    4. Right click on the first element on list

    5. Click on "Remove"

    6. Repeat steps 4 and 5 for the second element on list

    7. Click on "Detects Hardware change" (monitor icon)

    8. Reboot

    And check if the battery is read again by the OS. If not, then try to run a filesystem check and repair:

    1. Digit "cmd" in windows search bar

    2. Right click on "Command Prompt"

    3. Select "Run as Administrator"

    4. Digit "sfc /scannow" without quote and press ENTER

    Another info that I need: if your laptop is powered off, have you a led indicator, that tells you if the battery is charging?
