    Lenovo Y560 overheating with 12.04

    Hi,

    Recently i installed Ubuntu 12.04 as a dual boot along with Windows7. My laptop is a i7 processor(4cores) with 8gb ram and 1GB ATI Radeon 5400 graphics card.

    After logging in to ubuntu and working for say 20-30 mins my laptop getting super heated. I just do the basic stuffs like browsing, watching video and working on terminal(extensive ssh to remote servers). I have also worked with 10.10 and 11.04 previously but on that i never faced this over heating problem.

    I dont understand what causing this overheating.

    This app is what I've used in the past, but it doesn't work on 12.04 out of the box due to this bug:

    HTML Code:
    https://bugs.launchpad.net/tp-fan/+bug/480700
    I found that I had to maniuplate some BIOS settings to max performance for both cpu and thermal. Then the best I could do on my W500 was level 7, which is only ~3000 rpm. I found that you can use these commands to set the level.

    HTML Code:
    http://www.thinkwiki.org/wiki/How_to_control_fan_speed
    However, level 7 wasn't enough for dual-monitor using the discrete graphics, ATI in my case with open src drivers.

    I was able to use this command to get it to 4900rpm

    Code:
    echo level full-speed | superuser tee /proc/acpi/ibm/fan
    where superuser is sudo of course

    This however was temporary and I had to create a loop in bash to run it every 30 seconds or so.

    Code:
    #!/bin/bash
    
    while :
    do
    
    	echo level full-speed | superuser tee /proc/acpi/ibm/fan
    	#echo "Press [CTRL+C] to stop.."
    	sleep 30
    done
    HTH,

    Mike
