Overheating problem on Macbook white 13.3" A1181 (Mid 2009)
Hello there,
I request your help on this, I have a Macbook 13.3" A1181, Mid 2009, and several days ago, I started to experienced that my laptop goes off due overheating, I mean it turns off by itself, beacuse of the heat issue. As you may notice, I'm out of warranty.
Things that I did until today to solve the trouble:
1. I downloaded smcFanControl, founding 0RPM, so this made me think that the fan was over. The temperature showed on it was increasing, as I expected due the fan stopping.
2. So, I opened the case without any problem and checked the status of the cooler fan (Remember that this model only has one fan). I found dust on it that I cleaned successful, I took off the heatsink and the fan, and also I changed the thermal paste in both chips, GPU and CPU without any problem, I'm very careful on electronical parts handling.
3. Once I turned on my Macbook, nothing happens, no noise from the fan. So, I downloaded this time the iStat Menus and you can see the following screen capture:
So, does it mean that the problem was the sensor on the board?,
What is exactly "HeatPipe Heatsink" and "Fin Stack"??
how can I confirm it and how can I change (if neccesary)
This is the first serious issue on my Mac, my laptop has been on tech service only once through the Apple program to replace the top case cover (Due the known plastic's broken problems), no more.
Hope that you could lend me a hand on this. I want to keep this lovely machine running at least 10 years more 🙂
Thank you very much!!
Regards.
MacBook, OS X Mavericks (10.9), A1181
