to prevent your computer from overheating
to prevent others from watching your monitor
to save batter power

1. select the correct power states:

start, shut down, wake, and sleep
start, run, sleep, shut down
start, run, shut down
start, sleep, shut down

Explanation:

1. Changing the power state of a computer, such as putting it to sleep, is a common way to save battery power. Overheating prevention is usually managed by cooling systems, and preventing others from watching the monitor is more about privacy settings (like locking the screen) rather than power - state changes.
2. The common power states of a computer are Start (booting up), Run (normal operation), Sleep (low - power state), and Shut down (completely powering off). "Wake" is not a power state but an action to get out of sleep.

Answer:

1. to save batter power
2. Start, Run, Sleep, Shut down
