Powermac Shuts Down Because of Thermal Runaway

Asked By Adam_roberts 0 points N/A Posted on - 11/03/2011

I have a powermac with a 1.8 GHz processor.  Recently, it shuts itself down without any interference from me.  The notification says that it has something to do with thermal runaway.  When it reaches to 65 degrees C, it shuts down.  Should I change my CPU?  Or is there anyway I can remedy this without having to purchase another one?

Powermac Shuts Down Because of Thermal Runaway

 

Hello there! The first thing you need to do when this thing happens is to check the fans and the exhaust for dust build up. Always keep the inside of your powermac dust free. Also, check the thermal paste or compound in the cpu if it needs replacement. If these do not resolve the issue, you should bring your powermac to your local apple store so they can run a diagnostic test in it. Usually, the processor is broken and needs to be replaced. I hope you saved up money for that because that is quite expensive.

Good luck to you!

Powermac Shuts Down Because of Thermal Runaway

No, you don’t need to replace the processor. It won’t fix the problem. It might even worsen the situation. That’s normal for laptops, actually. It happens when your laptop starts ageing. It shuts down because the temperature of the CPU reached the maximum limit. The CPU has its own cooling system and if this is happening to your laptop that means the cooling system is no longer working properly.

The cooling fan on the CPU probably needs cleaning and this requires technical knowledge because the laptop itself needs to be stripped down and there are plenty of small parts inside. You need to remove the back cover and disconnect everything up to the motherboard to access the CPU where the cooling fan is located.

The best option to fix this and prevent the laptop from suddenly shutting down without disassembling it is to purchase a laptop cooling pad such as this one: HAVIT Laptop Cooler Cooling Pad.
