    Display dims on battery power, even when fully charged.


    Hi All,

    An annoying problem here, can you please help me.

    My laptop display dims on battery power, even when fully charged. Every time I need to readjust the brightness. I went through the settings I could not get the setting where we set brightness for Battery and Plugged-in separately. I searched through all the Power Options. Probably it is a new upgrade from Microsoft.


    Something like this:
    Display dims on battery power, even when fully charged. [​IMG]


    I could not find this in my settings.


    I am on version: Windows 10 Enterprise version 1903 (OS Build 18362.900). On a Thinkpad T14s Gen 1. Ryzen 7.

    Can I go under the hood and do something about this automatic brightness switches.

    Any quick help will be greatly appreciated.

    :)

    Battery fully charged, but still charging


    My laptop has a battery light which tells me when my laptop is fully charged. When it is fully charged (it is green), Windows still says "05 minutes until fully charged" and then charges for another half hour. In the past the light has been reliable, so I believe that windows 10 is the issue. My laptop has also had significant issues with charging. I can confirm this with two batteries. I have an Asus K55VD which I haven't changed the battery plugs in or anything like that. What could my problem be? Here's what I've tried:

    -Disabling and re-enabling Microsoft ACPI-Compliant Control Method Battery (no change)
    -Turning power saving off in BIOS (did a bit of help with the charging problem)
    -Fixing the fan (turns out it wasn't spinning, which caused a range of issues. Helped the battery charge issue a bit)
    -Keeping the laptop shut down (didn't help)
    -Keeping it asleep (didn't help)
    -Keeping it on with the screen off (did help it charge)

    Yet I can't find a fix for the battery charging percentage and time issue. Any help would be appreciated.
