The balanced plan is a compromise. A duplicate of the high performance plan with tuned processor and PCIe settings gives full clocks when you need them and silence when you do not.
Duplicate a scheme with **powercfg /duplicatescheme**, set the processor and PCIe values per subgroup, then activate it with **/setactive**. Keep the original scheme as the fallback.
**/list** prints a GUID per scheme, and the GUID is what every later command needs. Write down the identifier of the plan you are about to copy.
powercfg /list
powercfg /getactivescheme
powercfg /l | Select-String -Pattern 'GUID|Power Scheme'**/duplicatescheme** creates an editable copy and leaves the original untouched. That copy is what you tune, and the stock plan stays available as a reset path.

:: copy the new GUID from the output**PROCTHROTTLEMIN** is the minimum state and **PROCTHROTTLEMAX** the maximum, in percent. A low floor keeps the CPU cool when idle; the boost mode decides how far it may go under load.

powercfg /setactive $g**PCIEXPRESS** link state power management can add latency to a GPU or an NVMe drive. Disabling it costs a few watts and removes a class of stutter.

powercfg /energy /duration 60A tuned plan can raise idle temperature and power draw. Switching back is one command, and the stock plans are never deleted.
powercfg /setactive SCHEME_BALANCED
powercfg /list
powercfg /delete $gAnother tool rewrote the schemes. Check the vendor power utility and Group Policy; both can replace the active scheme at logon.
PROCTHROTTLEMIN was set too high or the firmware forces a performance mode. Set the minimum to 5 percent and check the firmware power profile.
Settings shows only plans it recognises. The control panel power applet and powercfg /list show every scheme, including the duplicate.
The boost mode and the higher floor are the cause. Set PERFBOOSTMODE back to 1 and the minimum to 5 percent, then measure again.
Not meaningfully, but it raises idle power and heat. On a desktop the difference is a few watts; on a laptop it halves battery runtime.
Yes, it is an extra scheme with latency-focused defaults. Duplicate it with powercfg /duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 on editions that expose it.
Only the AC values. Setting the DC values the same way drains the battery, so leave the battery side on balanced.
Activate the stock plan with powercfg /setactive SCHEME_BALANCED and delete your duplicate with powercfg /delete <guid>. The built-in schemes were never modified.
