Recently a friend installed a regulator on my Mac Computer. I used it to 'safely' shut down the computer when a sudden thunderstorm occurred. The Mac in question was old by computer standards but up to this moment worked perfectly with no signs of trouble. The next morning my computer was completely and utterly dead with no power supply. Could the voltage regulator have caused this problem?

I suspect it may depend upon the quality of the regulator, so Make/Model number might help someone answer this. – pnuts Jan 16 '13 at 17:41
You're going to have to tell us what this "regulator" was for. Do you mean UPS or surge protector by any chance? If not what was this regulator supposed to do? How did you "safely" shut down? – Mokubai Jan 16 '13 at 18:59
