So my trusty PowerBook G4 finally turned up it’s toes after 6 years of faultless service. What happened? One warm evening the screen went black and never came back; my diagnosis is one fried GPU. So far so what; computers die every day right? What makes this different is why the poor bugger got too hot…

Front and centre on my desk is my work laptop; a big old HP Workstation, and the PowerBook always sat to it’s left. If only I noticed months ago that the exhaust vents for the cooling are at the back left corner, and that the intakes for the PowerBook are along the back behind the screen hinge…

So I checked the specs – the PowerBook’s top operating temp is 35ºC. The ambient temperature in the room was 26ºC. Then I put the thermometer behind the Mac….  33ºC! Okay so supposedly the Mac can take that, but for days and weeks on end?? I would imagine not.

Moral of this sad story? Always check where your laptop gets it’s cooling airflow from. Oh, and the new Macbook Pro now sits on the right hand side of the killer PC ;o)
