STEP 01
Start with the trade-offs
Keeping a computer awake consumes power. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Before changing behavior, estimate how long the task needs to run and whether power is available.
- Check the current battery percentage and health.
- Estimate the time your task needs to finish.
- Move to a cool, hard surface with clear vents.
STEP 02
Review your battery settings
macOS settings can differ by version and model. Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium.
- Open System Settings and find Battery options.
- Review sleep-related choices for battery power.
- Note your original configuration before testing changes.
STEP 03
Test briefly and monitor
A short controlled test is more useful than assuming a setup will behave the same in every environment. Lorem ipsum dolor sit amet, consectetur adipiscing elit.
- Run the task for a few minutes with the lid state you need.
- Check battery level and warmth after the test.
- Return to normal sleep behavior when the task finishes.
