Power plans are not changing the CPU speed ?

1. Quickly restore the default power plan
Run CMD as administrator:
cmd
powercfg -restoredefaultschemes
Reselect the scheme:
Win + R → type powercfg.cpl → select ‘High Performance’
2. Force CPU speedup to be enabled
 Registry modification:
Open Registry Editor (regedit)
Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Create a new DWORD value:
Name: CsEnabled
Value: 0
Restart the computer.
3. Processor Power Management Settings
Adjust the min/max status manually:
Current Power Plan → Change Plan Settings → Change Advanced Power Settings
Expand:
Processor power management → Minimum processor status (set to 5-20%)
Maximum processor status (set to 80-100%)
4. Driver and firmware check
Critical Updates:
Update chipset drivers (download from motherboard manufacturer's website)
Update BIOS (some vendors will lock CPU regulation)
Uninstall third-party power management software (e.g. Dell Power Manager)
5. Ultimate troubleshooting tools
 Use PowerCFG Diagnostics:
cmd
powercfg -energy # Generate a power efficiency report
powercfg -list # View all available power plans
