The fan never stops
I upgraded my macbook pro 13" mid 2009:
replaced optical drive with 250GB SSD.
replaced 2x2GB RAM with 2x4GB.
replaced old battery..
Things work, except the fan never slows down and makes a lot of noise.
The fan start at full speed as soon as I click the power button, even before the screen lights up.
Please help.
Also the bluetooth and camera stopped working :(
Is this a good question?

Okay I ran AHT.
It shows error: 4SNS/1/40000000: TB3T-128.000.
Searching over internet it says it's an error in battery temperature sensor. That sounds plausible as I did replace the battery and can also explain the fan running high all the time (even before anything else turns on in the laptop).
Any ideas, how to fix it?
