if i remember right there was a software glitch when you lost power and the battery on the board was dead. When the RAM is dumped due to a bad battery backup the hospital emergency input/KPWR would not reset. you had to use the tool and force it on like you did. you must also tell it the halfway count for EQ operation(atleast here in cali) when the battery dies. hope my memory helps, the miconic a job i had was modded a few years back.
