IF YOU TRY TO USE A STANDARD 4 PIN POWER ADAPTER THAT IS WIRED NORMALLY, IT WILL NOT WORK AND YOU WILL DAMAGE YOUR MACHINE'S MOTHERBOARD. I HAVE RECEIVED DOZENS OF CALLS OVER THE YEARS FROM OWNERS WHO HAVE TURNED THEIR MACHINE INTO A BOAT ANCHOR BY PLUGGING IN A NORMALLY WIRED 4 PIN POWER ADAPTER THEY HAD LAYING AROUND FROM A DIFFERENT DEVICE-->PLUG MAY LOOK THE SAME, BUT (+) AND (-) PIN LOCATIONS ARE REVERSED.
IT'S LIKE CONNECTING THE POS AND NEG WIRES ON YOUR CAR'S BATTERY BACKWARDS AND THEN TRYING TO START THE CAR, IT WON'T END WELL. THIS DEVICE REQUIRES THE 2 LEFT PINS ARE (-) NEGATIVE, AND 2 RIGHT SIDE PINS ARE (+) POSITIVE, WHICH IS NOT HOW 99% OF 4 PIN ADAPTERS ARE WIRED.
