    HDD cache flushing - on battery vs plugged in


    Hi everybody, my laptop has a primary SSD and a secondary HDD. After trying all possible drivers, the best behaving one is fine when my PC is plugged in but on battery the bad HDD spindown behaviour comes back. Hence, I am trying to find at least all of the Windows 10 parameters that change between AC and DC so that I get the correct behaviour on both batter and plugged in.For now, if anyone knows something about this, I'd be glad to know where are all the SATA/HDD settings in the registry that could interfere with the HDD spindown policy.Until now, I've already been changing the default DC va

    Flush DNS Cache

    New:

    DNS Cache Viewer (DCV)

    The purpose of DCV is to allow you to view what Windows has in it's local DNS Cache, and allow you to flush it if you want.

    Most of those cached entries are contained in HOSTS file. (27642 after excluding the first 5 lines)

    Plugged in but battery does not charge

    If the laptop works without the battery then charger is functioning correctly. Take a cloth with a bit of rubbing alcohol on it (or some on-the-go alcohol swabs), and clean the metal contacts that connect your battery to your laptop.

    Make sure to install all Windows important updates.

    Install latest versions of your laptop device drivers you can download the latest device drivers from the device manufacturer or from your laptop manufacturer website.


    Step 1

    1. Shutdown your laptop.

    2. Remove the battery.

    3. Connect the AC power adapter to your laptop.

    4. Power on the laptop

    5. Open the Device Manager by typing Devmgmt.msc into Start Menu or from Control Panel.

    6. Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).

    7. Shutdown the laptop.

    8. Insert the battery.

    9. Power on the laptop.

    If above suggestions wont resolve the battery charge issue then follow below steps.




    Step 2

    1. Shutdown the laptop.

    2. Remove the battery.

    3. Start the laptop with only AC adapter connected to laptop.

    4. When you login to Windows OS connect the battery while Windows OS working.





    Step 3

    Reset the System Management Controller. Use one of these methods to reset the SMC, which controls battery management, battery status light.

    1. Shut down the computer and disconnect the power cord.

    2. Remove the battery.

    3. Press and hold the power button for ten seconds.

    4. Reattach the battery and AC power adapter, then start up the laptop.


    Hopefully one of the above suggestions will help you resolve the battery not charging problem. If battery still doesn't charge, you may need to replace your battery.

    Flush DNS Cache

    Personally I disable the service using Autoruns before rebooting and flushing then re-enable the service.
