Power modes explained
M-Tech Power Modes Explained
This page explains how the M-Tech Power Modes script configures Windows power plans on M-Tech systems. It provides Quiet Mode, High Performance, and Ultimate Performance in a safe, reversible, and predictable way.
M-Tech Power Modes Tool
Engineer-grade behavior, customer-friendly safety.
The Power Modes script allows a technician or power user to switch between three tuned power modes using a simple menu. All changes are reversible and do not modify BIOS, firmware, or registry settings.

Overview
Ultimate Performance: maximum responsiveness and minimum latency.
High Performance: strong performance with standard high-performance behavior.
Quiet Mode: reduced CPU aggressiveness and passive cooling for lower fan noise.

The script duplicates existing Windows plans, tunes them, and activates the selected plan. It never deletes system plans or makes permanent changes.
How the Script Works
Technician Summary
What the script does:
- Checks for administrator rights.
- Shows a menu for Ultimate Performance, High Performance, Quiet Mode, or Exit.
- Duplicates an existing Windows plan for each mode.
- Renames the duplicated plan clearly.
- Tunes CPU and cooling behavior inside the new plan only.
- Activates the new plan immediately.
- Checks for administrator rights.
- Shows a menu for Ultimate Performance, High Performance, Quiet Mode, or Exit.
- Duplicates an existing Windows plan for each mode.
- Renames the duplicated plan clearly.
- Tunes CPU and cooling behavior inside the new plan only.
- Activates the new plan immediately.
What it does NOT do:
- Does not delete Balanced, High Performance, Power Saver, or OEM plans.
- Does not edit the registry.
- Does not change BIOS or firmware.
- Does not disable CPU cores or turbo boost.
- Does not modify drivers or system files.
- Does not delete Balanced, High Performance, Power Saver, or OEM plans.
- Does not edit the registry.
- Does not change BIOS or firmware.
- Does not disable CPU cores or turbo boost.
- Does not modify drivers or system files.
You can switch back to any other plan at any time through Control Panel > Power Options.
Quiet Mode
Base plan: Windows Balanced
CPU behavior: maximum processor state reduced (around 70%).
Cooling policy: passive (lower CPU speed before increasing fans).
Effect: lower fan noise, lower temperatures, smoother acoustics.

Cooling policy: passive (lower CPU speed before increasing fans).
Effect: lower fan noise, lower temperatures, smoother acoustics.
High Performance
Base plan: Windows High Performance
CPU behavior: min/max at 100%.
Cooling policy: active (fans ramp sooner to sustain frequency).
Effect: strong performance for gaming, heavy apps, and demanding workloads.

Effect: strong performance for gaming, heavy apps, and demanding workloads.
Ultimate Performance
Base plan: Windows Ultimate Performance
CPU behavior: aggressive frequency scaling, minimized idle states.
Storage: reduced power saving for lower NVMe latency.
Responsiveness: reduced timer coalescing and idle consolidation.
Best for: CAD/CAM, 3D rendering, scientific workloads, audio/video production, virtualization, and multi-monitor setups.

High Performance vs. Ultimate Performance
| Aspect | High Performance | Ultimate Performance |
|---|---|---|
| Goal | Keep system fast with minimal power saving. | Eliminate as much latency and jitter as possible. |
| CPU States | Min/max at 100%, reduced idle throttling. | More aggressive about avoiding deep idle states. |
| Core Parking | Generally minimized. | Fully disabled; all cores kept ready. |
| Storage Power Saving | Some power saving may remain. | Reduced for lower NVMe latency. |
| Latency Tolerance | Standard high-performance behavior. | Lower tolerance for micro-latency. |
Technician Usage
The script is designed for predictable, repeatable behavior. It is menu-driven, admin-checked, and safe for remote sessions. It can be updated as M-Tech adds new modes or refinements.
This document explains how the M-Tech Power Modes script interacts with Windows power settings for both technicians and advanced users.
