I would like to know which are the right ways to reset an Intel Mac Mini. It all begun a few months ago when my Mac Mini didn't make the regular sound when booting, so I searched on Google and did a so called PMU reset, which wasn't the thing to do it seems after all and the soft reset option + command + P + R at booting, which seems to have helped at that time. Recently my Mac was slower, had difficulties rebooting, applications crashed, all kinds of strange things. The PMU reset resulted in heavy fan noise and loud beeping this time without result. After some extra search it seems that the Mac Mini needs a SMC reset.
As described on the Apple web site: 1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off). 2. Unplug all cables from the computer, including the power cord and any display cables. 3. Wait at least 15 seconds. 4. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer. 5. Press the power button on the back to start up your computer.
It is not clear to me if you can reconnect all other cables when reconnecting keyboard and mouse (step 4). Anyway, I did exactly as written (only keyboard and mouse, no video or anything else), waited a few minutes after booting, then powered my Mac off, reconnected all other cables, rebooted and since then my Leopard (after reinstall) and Mac work as a charm. I guess that this is the hard reset and I hope that I did it the right way this time.
Besides that, in case of problems naturally, the only other thing to try is a soft reset: option + command + P + R ? Or does the hard reset also include the soft reset in a way ?
Thanks in advance for helping me out !

Hi Beliarus-Greetings and welcome to the Apple boards.You should connect the video cable to the monitor in step 4, as you will need to see what you are doing in order to shut down properly.However, if the monitor has any USB or FireWire hubs or ports built-in, it is wise to leave those parts of the cable disconnected when connecting video at the Mini. The mouse and keyboard should each occupy their own USB port on the Mini for best results.Luck--DaddyPaycheck

Thanks for your helpful reply. However, I'm still wondering if the SMC reset includes all other possible resets like PRAM and NVRAM or should I still try the option + command + P + R ? In other words, is it the ultimate complete reset you can do on an Intel Mac ? It is just to know it the right way, because since the last SMC reset I described everything is stable and fast without any trouble whatsoever, so I prefer to leave things unaltered and be sure about the procedure when needed.
Thanks for replying. Although the difference between the two resets is not yet completely clear to me, I now know how to execute the two available resets for an Intel Mac Mini the right way. Let's put it this way: in a PC bios you just "reset to factory defaults". Although EFI seems quite better than the old regular PC bios, there is no interface and you get special procedures for resetting SMC, PRAM and NVRAM, which is a bit confusing in the beginning.
