 ## Notes & Caveats
 
 - Requires Administrator rights (scripts self-elevate via UAC prompt).
+- If you get "running scripts is disabled on this system", either run the script via
+  `powershell -ExecutionPolicy Bypass -File .\Test-BatteryDrain.ps1`, or once per user run
+  `Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser`. If the files were
+  downloaded rather than created locally, also run
+  `Unblock-File -Path .\Test-BatteryDrain.ps1, .\Restore-PowerSettings.ps1`.
 - `Test-BatteryDrain.ps1` does **not** auto-restore settings when it finishes or is interrupted
   with Ctrl+C — always run `Restore-PowerSettings.ps1` afterward to revert the system to its
   normal power-saving behavior.
