Which action can wake a computer without changing any data?

• A. Move the mouse
• B. Delete a file
• C. Install software
• D. Format drive

Answer: (A)

Waking the computer from sleep is designed to be triggered by user input that doesn't modify data. Moving the mouse sends an input signal to the system to resume activity, so the CPU and display wake up while memory and storage stay unchanged. In contrast, deleting a file, installing software, or formatting a drive would involve writing to storage or changing its structure, which alters data. So, the action that wakes the system without changing any data is moving the mouse.
