I have found my own solution

first command

`$Plan = powercfg /getactivescheme

$Plan -match 'Power Scheme GUID: (?<gu>\w\w\w\w\w\w\w\w-\w\w\w\w-\w\w\w\w-\w\w\w\w-\w\w\w\w\w\w\w\w\w\w\w\w).'

$ExcistGUID = $Matches.gu

​

$Startdir = Get-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\' -Name 'Local AppData' | Select-Object -ExpandProperty 'Local AppData'

$Tempdir = $Startdir + "\Temp"

$CachedPowerPlan = $Startdir + "\CachedPowerGUID.txt"

​

# Output plan GUID to file (Not forced so if script ran twice, it won't overwrite the first run)

New-Item -Path (Split-Path -Path $CachedPowerPlan) -ItemType Directory -ErrorAction SilentlyContinue | Out-Null

New-Item -Path $CachedPowerPlan -ItemType File -force -Value $ExcistGUID -ErrorAction Stop | Out-Null

$GUID = New-Guid

​

powercfg /duplicatescheme $ExcistGUID $GUID

powercfg /setactive $GUID

timeout 2

powercfg /change /standby-timeout-ac 0

$GUID2 = $Startdir + "\temppowerGUID.txt"

New-Item -Path (Split-Path -Path $GUID2) -ItemType Directory -ErrorAction SilentlyContinue | Out-Null

New-Item -Path $GUID2 -ItemType File -force -Value $GUID -ErrorAction Stop | Out-Null"`

then the command to reset and delete the temp power scheme
this was set up to run as two seperate files on an RMM

`$Startdir = Get-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\' -Name 'Local AppData' | Select-Object -ExpandProperty 'Local AppData'

$Tempdir = $Startdir + "\Temp"

$CachedPowerPlan = $Startdir + "\CachedPowerGUID.txt"

$GUID = $Startdir + "\temppowerGUID.txt"

$CachedPowerPlan = $Startdir + "\CachedPowerGUID.txt"; $CachedPowerGuid = Get-Content -Path $CachedPowerPlan; powercfg /setactive $CachedPowerGuid; $GUID = Get-Content -path $GUID; powercfg /delete $GUID`
