Recently i have installed Ubuntu 14.04 on my Lenovo G505s laptop along side win7. It has AMD A8-5550M APU with Radeon HD Graphis and 8 Gb of ram. But the problem is that i am unable to run ubuntu more than 40 min as my laptop become very hot.

I installed psensor and found out that temperature of my laptop was around 75 Celsius.Sometimes it become 80 also.I also found out my fan was not running.

It's not the hardware prob as fan is working while running win7.

I also installed TLP powersaver tool in ubuntu but then also no help.Still my laptop fan is not running.

Most likely your system has a bad ACPI bios that uses goofy non standard fan control mechanisms that require proprietary windows drivers and do not work in linux. Your only hope is to install the lm-sensors package and see if sensors-detect can find hardware that fancontrol knows how to take over.
