You may have noticed that High Performance power plan is missing some versions of Windows 10 especially when running on laptops. Only the Balanced plan is shown.
This is somehow connected to the Modern Standby. I couldn’t find any official statement from Microsoft about removing High Performance power plan.
On my laptop I’d set up High Performance power plan (for numerous of reasons). It is fact that after recent upgrade to 1803 this plan has disappeared from my laptop too. It’s been renamed to “My Custom plan 1”:
On some laptops you can still create it via Power Options > Create a power plan > Choose High Performance Power option:
But on some laptops (I’ve tried ones with Celeron and Intel Atom) only the Balanced option is present. The situation is the same when listing profiles with powercfg:
Some sources suggest setting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\CsEnabled to 0, but this hadn’t effect in my case.
The workaround is to set the Power Plan to High Performance using powercfg:
powercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
Powercfg will now show it as active:
The GUI will be updated too:
Of course choose the power plan wisely and use High Performance power plan only if absolutely needed. Think green!
Hope this helped!
