NOTE: Sometimes due to workload and/or ambient heat, your Mac's battery may be placed under stress, which can sometimes cause Upper Volta to claim your battery has a problem when its actually functioning normally. Usually, rebooting your Mac will clear the issue. However, if it does't, you may want to look more deeply at your battery.
