Actually, I just found out what it does. It removes the power from all components, as I mentioned earlier, but the affect of this is that the software interfaces between the BIOS and the hardware are severed and then the BIOS reestablishes those software interfaces between the BIOS and hardware when the computer is reconnected to power. This is coupled with the clearing of the computer's temporary memory. That way, if one of the software interfaces between the BIOS and hardware is malfunctioning, it is reset.

Rather interesting. You can read about it on Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English), and this makes perfect sense as to why so many computer problems can be fixed with a hard/hardware reset.
