I had the same problem with my old Acer timelineX. CPU could hit 95oC quite happily and shut down. To be honest I just ran Linux in a virtual machine on it in the end. It made the difference between 10h and 2h of battery life as well. This is not really linux's fault though. It has to fight with a hack job of an architecture, the mess that is ACPI and BIOS written by drunk monkeys. They really need to just fix PC architecture or get rid of it.
