How do I re-enable my modern standby sleep mode (S0)?

I followed a youtube tutorial to get back the power plans, which I managed but it included enable S3 and disabling S0.

I have a HP laptop of 2023, I have little to very few knowledge about computing and systems.

I feel like that modern standby sleep mode is better for my recent laptop but I couldn't find any tutorial to re-enable the modern standby.

https://www.youtube.com/watch?v=dbo78bDZU4E&t=241s this is the youtube tutorial, i followed the cmd steps to enable S3.

Now I have access to the power plans but I'm not sure of what I'm missing by disabling S0 and now I'm slightly afraid of the changes i gave to my computer.

I understand that if i was to re-enable S0, i would only have balanced for power plans and I'm fine with that.

If you feel s3 is better than S0, please let me know.

    Modern standby (S0) is indeed designed to allow for faster wake times, which can be convenient for many users. However, one drawback is that it doesn't allow the PC to fully shut down, which means it may continue consuming some power even when in sleep mode. Additionally, some users have reported issues with laptops becoming excessively hot when placed in their backpacks while in modern standby mode.

    On the other hand, S3 sleep mode is a deeper sleep state where the system is essentially powered down, resulting in lower power consumption. While wake times may be slightly longer compared to modern standby, S3 can be preferable for those who prioritize power efficiency and want to ensure their laptop doesn't generate excess heat during periods of inactivity. Here are the steps to enable Modern standby:

    1. Open Registry Editor:
      • Press Win + R to open the Run dialog.
      • Type regedit and press Enter to open the Registry Editor.
    2. Navigate to the Power Settings:
      • In the Registry Editor, navigate to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
    3. Modify the Registry Key:
      • Look for the PlatformAoAcOverride key.
      • If it exists, right-click on it and select Delete.
      • If it does not exist, you can skip this step.
    4. Enable Modern Standby:
      • Open an elevated Command Prompt (right-click on Command Prompt and select "Run as administrator").
      • Enter the following command to delete the registry entry that disables Modern Standby: reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride /f
    5. Restart Your Computer:
      • Restart your computer to apply the changes.

    Verify Modern Standby (S0) is Enabled

    1. Open Command Prompt:
      • Open Command Prompt as an administrator.
    2. Run Power Configuration Command:
      • Type the following command and press Enter:

    powercfg /a - This command will list the available sleep states. Look for "Standby (S0 Low Power Idle)" to confirm that Modern Standby is enabled.

    Thank you again, I will continue to use S3 despite asking the question, sorry for wasting away your efforts.

    But you were a huge help for me to increase my understanding about those functions.

    Have a good day, regards.

    If your priorities lie in Power Efficiency and Reliability, you might find S3 to be the preferable choice, given its lower power consumption and dependable sleep behavior. However, it's essential to verify that the laptop supports S3, as some modern devices may not be compatible.

    On the other hand, if Instant Access and Connectivity are your primary concerns, S0 could be a better fit due to its instant-on capability and ability to handle background tasks seamlessly. It's important to be aware of potential issues such as battery drain and overheating. I advice implementing measures to address these concerns.

    Based on personal experience, I would recommend S3 as it ensures the complete shutdown of the laptop during periods of inactivity, aligning with preferences for conserving power and maintaining reliability.

    Thank you very much for your anwser and for your time.

    I appreciate very much the effort you put into the steps, I really do.

    But before I make any changes, may you tell me what would be the best choice between S3 and S0 for a commun, daily use laptop?

    Thank you very much again.

    With all due respect, if you know that you have "little to very few knowledge about computing and systems" why would you attempt such an advanced change to your computer? In addition, do you really believe somebody knows what they're talking about just because they made a YouTube video?

    I apologize for the above.

    You cannot switch between S3 and Modern Standby. Switching is not supported. To change from Modern Standby to S3 or vice versa - provided you have firmware support - you need to reinstall the operating system. Here is how I think you should proceed.

    There are two separate things you need to address. One is reinstalling Windows and all your software. The other is making changes to your UEFI. The UEFI is not part of Windows. Rather, it is part of the firmware that HP installed on your motherboard.

    Therefore, the best thing you can do is to contact HP technical support and ask for their help. You can also contact other HP users in the Official HP User Community forum. You will probably need to reset your UEFI to its default settings and possibly re-apply HP's UEFI updates to date.

    Reinstalling Windows could be easier. Like other large computer manufacturers, HP includes a method that enables you to reinstall all the software that originally came with your computer. Instructions for this are on HP's website.

    Best wishes to you.
