    Hello everybody, I just got my first Thinkpad laptop, a T61 with T9300 processor, 2 GB of ram, Nvidia Quadro NVS 140M and a 7200 RPM Hitachi drive (160 GB). The laptop is behaving very well, but the fan is running all the time in the second "gear". I've rarely heard it slowing down. It's running at aproximately 3000 rotations per minute the moment I am writing this. It's very weird, I only heard it slow down to the first gear only a few times when I restarted the laptop. After a few minutes it rapidly speeded up back to second rotational speed. Temperatures seem normal... What the problem could be?

    Could I have not installed the drivers corectly?

    Hrmm.. perhaps set your battery levels so that your computer does not charge all the way to 100% - set the limit to something like 95%...

    the reason i say this is because the fan is always on when you charge your battery...

    so if you set the computer to stop charging at say 95%... then when you're on AC power and have a full battery from 95-100%... your comp will not charge...

    Try it out...

    How do I set the battery to stop charging when it reaches 95%%?

    double click on the green battery gauge in the taskbar, and click on "battery maintenance". You'll get a window with boxes to choose charging thresholds. (start charging at XXX and stop charging at XXX)

    Are you using vista or XP? Check which power management scheme you are currently using. If it's set for full performance, it may cause the fan to run faster. I personally use the "power source optimized" scheme.

    Second thing to check is to open the task manager and see if the CPU activity is above 50% when this happens. You may have some process running that makes the CPU run hot.
