Power off menu.

[FluffyOMC]

When someone clicks (Turn Off) on the "Turn off computer" menu it should close the tab, and when someone clicks (Restart) it should refresh the tab.

Some kind of power off seems to be already implemented:

const powerOffAnimation = keyframes`
  0% {
    filter: brightness(1) grayscale(0);
  }
  30% {
    filter: brightness(1) grayscale(0);
  }
  100% {
    filter: brightness(0.6) grayscale(1);
  }
`;
const animation = {
  [POWER_STATE.START]: '',
  [POWER_STATE.TURN_OFF]: powerOffAnimation,
  [POWER_STATE.LOG_OFF]: powerOffAnimation,
};

When is this code triggered?

[FluffyOMC]

Never right now. When I click "Turn Off" It shows the fake "C:\ Application not found"

[panmona]

Yes I know. I haven't found out yet by looking through the code where it would need to be added.

[FluffyOMC]

Me neither

Sounds interesting! But I prefer showing blue screen or shut down... screen.
btw the code @maracuja-juice mentioned is for grayscaling whole app when power off menu is visible.

Hmm which bsod error code?

[FluffyOMC]

How about this one? Seeing as we don't really have "Acpi Drivers" due to it being a website.

This BSOD means that the ACPI driver detected an internal inconsistency. BSOD error code 0x000000A3 may also show "ACPI_DRIVER_INTERNAL" on the same blue screen.

I suggest something like this but for XP: https://screen.now.sh/win10-crash
