Which is a method to save power on a laptop?

• A. Specify 'power save' mode
• B. Increase screen brightness to maximum
• C. Run a full system antivirus scan continuously
• D. Use multiple high-powered GPUs at once

Answer: (A)

Switching to a power-saving mode relies on a power management profile that lowers energy use by reducing CPU speed, dimming the display, and turning off nonessential features. This approach cuts power draw across multiple components at once, which is why it most effectively extends battery life during typical use. The other options increase energy consumption: making the screen brighter uses more power because the display is a major energy draw; running antivirus scans continuously keeps the CPU and disk active, draining power; and using multiple high-powered GPUs is designed for performance and consumes a lot of energy. So, enabling power-saving mode aligns with the goal of saving power on a laptop.
