that doesn't always work...just fyi, i needed to reset my comp so i did the 15 min battery disconnect and when i reconnected the battery nothing was different and even my clock and radio stations were still correct, so i disconnected again except left it overnight to see if there was some memory holding power and once again after 12 hours disconnected my radio stations and clock were still saved... unless i missed something, that should not have happened, btw i fully disconnected the battery, even tried the touching of cables(not connected to battery) trick and still nothing. i hope it works for you i just wanted to put my :twocents: from my own experience.
