How to know if the System Management Controller (SMC) has been reset? I've recently uninstalled Fan Control, and one of the steps of the uninstallation is that I need to reset the SMC.

So I've done that according to the instructions from the Apple website, however how can I be sure that it has been reset successfully? In particular, I wouldn't want the laptop to overheat because of incorrectly setup fans.

Is there any way to check all this (i.e. if the SMC and the fans are working as expected)?
Actually, as per my experience if you are going to do the SMC reset and your not fully charged battery Macintosh machine is charging, the charging indicator will be the reset indicator as below.

When battery is not fully charged:


Charging indicator is orange light when machine powered off.
Keep pressing Shift + Option + Control + Power for 10 seconds and indicator is still orange.
Indicator turns to green when release all keystrokes and keeps almost 1 second.
Light turns to orange then.
