How can I visually tell if my computer is in sleep/standby mode and not shutdown?

You can check the power light indicator of your computer to determine what power state it is in.

Sleep/Standby – The power light indicator will blink at a steady, consistent rate.
Shutdown – The power light indicator will not turn on at all.
Turned on – The power light indicator will be on, not blinking.

The power light indicator is typically located on or near the power button of the computer.
