There is a rapid CPU load from running Minecraft 1.9(15w31b). If for instance once the official release of Minecraft 1.9 in the near/distant future, someone loads Minecraft version 1.9 on an old and/or significantly under powered computer system, may result in: fire, CPU crash/damage, fan over use(damage to fan), CPU/GPU overheating(resulting in: crash/damage to computer), and/or battery over load. I suggest that this problem be looked into as the overload on this laptop results in rapid heating of the whole computer. This occurs once the program is open(after launcher hides in the system tray).
