but doesn't that mean firing up all sensors again, screen and other hardware required to display or perform the said warning, which will ofcourse create burden for the main battery again? I don't think CMOS/BIOS battery can be used for that task. And I don't understand why only Apple has to do everything, it's not like only Macs are known to burn. User must have minimum knowledge on laptop over-heating.
