How to manage power usage on intel laptops that come with an NVIDIA GPU ,Full guide for new Ubuntu users

This is what ChatGPT said about the above :

• This article provides a straightforward guide for managing power modes and NVIDIA Prime profiles on a Linux system with an Intel CPU and NVIDIA GPU. Here's a summary and some thoughts on its content:

Key Points of the Article:

1. System Power Modes vs. NVIDIA Prime Profiles:

   • System Power Modes: These affect the entire system's power state, influencing how both the CPU and GPU behave.
   • NVIDIA Prime Profiles: These specifically control the NVIDIA GPU's behavior, such as whether it's active, in on-demand mode, or running at full performance.

2. Power Modes:

   • Power Saver: This mode reduces power consumption across the system. In this mode, the NVIDIA GPU is disabled, and the integrated Intel GPU takes over, saving battery life.
   • Balanced: A middle ground where the system and GPU are optimized for everyday use, offering a balance between performance and power consumption.
   • Performance: Maximizes performance by enabling the NVIDIA GPU in its highest power mode and setting the system to prioritize performance over power savings.

3. Practical Tips:

   • Rebooting is necessary for the changes in NVIDIA Prime profiles to take effect.
   • You can switch system power modes without rebooting, but it's crucial to avoid illogical combinations (e.g., running the system in power-saving mode while setting the NVIDIA GPU to maximum performance).

Thoughts on the Article:

• Clarity and Usability: The guide is clear and practical, making it accessible for regular users who want to optimize their system's power and performance balance without diving too deep into technical details.

• Specificity: The guide is tailored for systems with Intel CPUs and NVIDIA GPUs, so users with AMD hardware may need to seek alternative guidance. However, the principles of balancing power and performance are broadly applicable.

• Importance of Rebooting: The emphasis on rebooting after changing NVIDIA Prime profiles is crucial, as many users might overlook this step and wonder why the changes haven't taken effect.

• Potential Risks: The warning against combining conflicting modes (e.g., power-saving with performance settings on the GPU) is a good reminder. Such combinations could lead to suboptimal performance or even system instability.

Suggestions for Improvement:

• AMD Considerations: It might be helpful to add a brief note on how these settings might differ for AMD CPUs and GPUs, or at least mention that users with such hardware should look for specific instructions.

• Visual Aids: The included images could be better annotated or explained to make it clear what they represent and how they relate to the guide.

Overall, this article is a practical resource for users looking to manage their power and performance settings effectively on a Linux system with Intel and NVIDIA hardware.
