Have you been having problems with your MacBook suddenly shutting down by itself? Well thanks to a certain German engineer who took it upon himself to break down and snoop around his MacBook, we now have a simple DIY solution to this predicament.

According to the German engineer, the cause for these shutdowns is the heat sensor cable found next to the CPU's heat sink. What happens is that when the heat sink expands as you use your laptop, the heat sensor cable touches the sink and melts its insulation. The result? Cable is shortened and MacBook is turned off. And after the heat sink cools down and shrinks, your MacBook can now be turned back on.

What to do: bust open your case and cover the affected areas of the sensor cable with some insulation tape. Now unless the tape also melts, you shouldn't have any problems with sudden shutdowns anymore. A little warning though, doing so may (or may not) void your warranty. Our "Germengineer" isn't sure about this so it's still best to get Apple to fix it for you. But if the sudden shutdown is majorly pissing you off, you can try this simple solution and see if it works.
