Dell XPS Doesn't Return From Modern Sleep

(2026-07-24)

Problem:

Laptop does not wake up properly from sleep mode. Might wake up immediately, might require multiple close/opens of lid to wake up, might not wake up at all.

Logs point finger at "returnign from Modern Sleep mode" or the like.

Solution:

Google clanker suggests this powershell to do this needful remotely:

# Define the target laptop's name or IP address
$ComputerName = "BustedDellXPS"

Invoke-Command -ComputerName $ComputerName -ScriptBlock {
    # Path to the Power registry settings
    $RegistryPath = "HKLM:\SYSTEM\CurrentControlSet\Control\Power"
    
    # Inject the Modern Standby override DWORD
    New-ItemProperty -Path $RegistryPath -Name "PlatformAoAcOverride" -Value 0 -PropertyType DWORD -Force
    
    # Restart the laptop to apply firmware-level power state changes
    Restart-Computer -Force
}
