How does a dead battery prevent a reboot? The battery is isolated by a series diode to prevent it shunting the circuit. Certainly some parameters will be lost (eg time) but it should still boot. Whatever, it's easy to test. Simply remove the battery from your PC and see if it will reboot. Then clip a lead across the (vacant) battery holder to see if a shorted battery prevents a reboot.
