cpu 71 - -

what can i do?

Those temperatures are normal.

man, that was my "normal temp" when it started

i t can be as high as 71 on CPU

They'll do that, especially when under a high workload. Mobile CPUs are designed to withstand some pretty extreme temperatures (safe operation up to 100 degrees C)

but my legs can't afford 100 degree..

I am not sure that they are. The X60s and X61s that I have experience with do very seldom reach CPU temps of 71C. Only when doing 100% CPU intensive tasks for longer time periods (i.e. MPEG 4 compression) and running 100% clock speed, they start to approach 70C.

I have little experience of VISTA. If you have XP you can do the following to reduce heat:

1. Install SpeedSwitchXP and use "dynamic switching" or "max battery" profile to reduce CPU heat (max battery will significantly reduce temperature at the expense of the clock speed)

2. Depending on your WIFI-card, try to enable maximum power saving and minimum transmit power (this will reduce range of wifi but if you are not to far away you will not notice any difference).

3. Install tpfancontrol and set it to manual and step 7. This will keep the internal fan running at maximum speed regardless of temperature.

4a. If you happen to have the Atheros wifi-card, swap it for the Lenovo's Intel 3945 wifi-card (note: you must buy a lenovo wifi-card)

4b. If you happen to have the Atheros or Intel 3945 card and feel adventurous, swap in Lenovo's Intel 4695 wifi-card. This however, requires you to obtain a modified X60 bios with disabled white-list functionality, in order to get the 4695 card to work.

As a point of interest, when you are running on battery power, how what is your energy consumption according to the Power Manager Gauge?

Make sure you aren't covering the fan intake which is on the rear left corner on the bottom surface.

I find the Ultrabase will block this intake and I need to jam a bit of cardboard between the X61 and the Ultrabase to allow airflow. This reduces CPU temp by about 10 degrees and lowers the fan speed.
