Perhaps you could show us your laptop hardware configuration? You can copy and paste the result of following command line :

 sudo lshw

In case you do not have lshw application in your ubuntu, following command line would install it from debian repository:

 sudo apt-get install lshw

Did you notice anything conspicous from dmesg result last time I ask you? How about paste it here as well?
