Both, it must be grounded and must have power.

There is no power to it. The 'protected' light indicates that the filter circuit is operational and has power to it. The 'grounded' light indicates whether a device is properly grounded. But it still needs power to the surge protector to light it.
When working inside a monitor, inside a power supply or inside another high voltage peripheral such as a laser printer or scanner. The reason is that these components contain a powerful electrical charge even after they are disconnected from power. You don't want to be grounded because you provide yourself as a conduit for the voltage to discharge through, which would suck.
You can use a power bar to ground yourself if it's plugged in. Since the ground wiring normally bypasses the on/off switch, it doesn't have to be turned on either.Additonally, if you are working on a computer that has an on/off switch on the power supply, you can keep the computer case grounded by leaving the power supply plugged in with the switch off. This offers an additional layer of protection from electrostatic discharge.
