Creating a custom power plan in Windows lets you fine-tune how your PC manages energy, balancing performance and battery life. Whether you're on a laptop or desktop, you can set specific settings for when your computer sleeps, the display turns off, or how the processor behaves. Here's how to create a new power plan in Windows.

Open Power Options

First, access the Power Options settings:

• Press Windows R to open the Run dialog.
• Type powercfg.cpl and press Enter.
• This opens the Power Options control panel.

Alternatively, you can:

• Go to Settings → System → Power & battery (on laptops) or Power & sleep.
• Click Additional power settings on the right side to open the classic Power Options window.

Create a New Power Plan

In the Power Options window, you’ll see the current power plans (like Balanced, Power Saver, High Performance). To make a custom one:

1. Click Create a power plan in the left-hand menu.
2. Choose a base plan to start from — for example:
   • Balanced (good for most users)
   • Power Saver (prioritizes battery life)
   • High Performance (best for desktops or gaming)
3. Give your plan a name (e.g., "My Custom Plan").
4. Click Next.

Customize Your Plan Settings

Now you can adjust key settings:

• Turn off the display after: Choose how long until the screen turns off when idle.
• Put the computer to sleep after: Set when the system goes to sleep.

After clicking Create, your new plan will be active. But you can further tweak it:

• Click Change advanced power settings on the right.
• A window pops up with detailed options:
  • Hard disk → When it turns off
  • Sleep → Sleep after, hibernate after
  • Processor power management → Minimum and maximum processor state, cooling policy
  • Display → Dim settings, adaptive brightness
  • Battery → Low and critical levels, what happens when reached

For example, you might:

• Set Maximum processor state to 90% on battery to save power
• Disable Hard disk shutdown on AC power for constant access
• Enable Adaptive brightness only when on battery

Apply and Use Your Plan

Once you're done:

• Click OK to save advanced settings.
• Your new plan will appear in the Power Options list.
• To switch to it, just click it and click Choose plan.

You can also set it as default or delete it later if needed.

Note: If you're on a laptop, you can set different behaviors for on battery vs. plugged in — make sure to check both in the advanced settings.

Creating a custom power plan isn’t hard, and it’s a great way to get the most from your battery or boost performance when needed. Basically, just pick a base, tweak the timing and processor settings, and let Windows do the rest.
