Thinkpads Forum

TPFanControl shows 55 C for pwr. It normally says CPU or GPU when I'm at home using my Antec Notebook cooler. I'm at school studying and the computer is relatively warm as I type w/ my palms on the palmrests and pwr is 55. Seems kind of weird that my power supply is warming up the computer....

Sorry. Anybody have an answer as to what pwr means?

I'm away from my cooler and fan is using BIOS settings (so the fan is running) and my gpu says 47 C. PWR is showing up as 41 C. I guess it doesn't mean anything?

I was a little concerned about the safety of my computer b/c I'm going to be ordering a genetic battery soon.

Generally speaking, the largest heat generators in any laptop (or desktop for that matter) are the CPU and GPU. Any other sensor may or may not be important depending on the machine. For Thinkpads, if the GPU and CPU are being cooled properly, my experience is that you can ignore the others except for the hard drive. That must run below specs for temperature or it's life will be shortened. If you look at the below link (it's for Linux but you can see the sensors) it will tell you what the sensors are. Based on the information there, the 'pwr' sensor for a T61P is temp11, and it's by the Mini-PCI area. Turn your wireless off and see if it goes down. At any rate, I would not worry about it, again as long as the CPU and GPU are being actively cooled and nothing has changed. If you suddenly see a drastic upswing in GPU or CPU temps under a similar load as compared to a past point in time, then you my need to pay attention to cooling. Or, if you see any temperatures approaching 90*c....that's bad mojo there.
