How to disable Modern Standby?

The ACPI sleep states S0 to S5 are familiar to many users. However, the ACPI specification actually describes several different power states. One of these is the CPU (C) power states.

ACPI allows processors to enter a reduced power state – to effectively sleep – and modern hardware makes this possible. The CPU power states apply when the global state is G0. The C states are:

C0 – the CPU is actively executing instructions;

C1 – the CPU is not actively executing instructions, however it can resume executing instructions almost instantly; and

C2 and C3 – the CPU is in a reduced power state; no instructions are being executed and the processor consumes less power; C2 and C3 are sometimes called Deep Sleep, because they represent progressively deeper levels of power-saving compared to the more shallow sleep states like C1.

ACPI allows vendors to define additional power saving states beyond C3. Since these are vendor-specific, you'll have to ask the manufacturer of your computer to explain them,

Can anyone explain the C1, C3 ,C6

C7, C8,10

Ayushmaan, thank you for your reply.

If you have already tried the command prompt method and applied the registry file from the Eleven Forum website but are still encountering issues, it's possible that the registry key might be missing.

In your situation, it appears that disabling this option in the BIOS isn't possible. To resolve the issue, it's best to contact your PC manufacturer for assistance in exploring potential BIOS settings and making necessary changes.

Meanwhile, please check the registry settings below.

1. Open the Registry Editor and navigate it to

Computer\HKey_Local_Machine\System\CurrentControlSet\Control\Power

In the right pane, select, New > DWORD32 bit value and name it as PlatformAoAcOverride and set the value data to 0.

Restart your PC.

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

It may not support being disabled then. :(

You cannot switch between Modern Standby and S3 simply by changing a setting in the UEFI. Switching is not supported - it requires a complete OS re-install.

Modern Standby has important advantages over S3, which is why many PC manufacturers no longer ship with S3 or support it. I think it's in your best interest to reconsider.
