Battery too hot? Fan not spinning down.

[Tinus]

Hi,

I noticed that my fan isn't spinning down after a cooling period.
When my laptop is doing almost nothing...the fan starts, but doesn't stop by itself. By the pulsating sound it seems that it's trying to stop though.
Only when ik activate the 'lowest' power scheme (again) it sometimes stops. (note: the lowest scheme is the default...i just kind off re-activate it)

Anyone familiar with it? I think it's the battery temp.

In fancontrol it looks like this:
CPU 38°C (0x78)
APS 49°C (0x79)
PCM 33°C (0x7a)
GPU 0°C (0x7b)
BAT 50°C (0x7c)
BAT 27°C (0x7e)
BUS 36°C (0xc0)
PCI 41°C (0xc1)
PWR 43°C (0xc2)

I also have this problem when the battery is being charged.
I run both power manager and notebook hardware control software. Disable one or the other doesn't help.

the battery is at 50C?? that seems way too high to me, but only through my observations. ive only seen up to 35C on a number of thinkpads.

when i used NHC, it completely messed up my r40. i had default settings- i now just use power manager and mobilemeter to check the temps.

I haven't personally measured the battery temps on the Z60; but 50° C does indeed seem too high. My battery temperature is around 36° C when I am pushing everything to the limit; around 24° C otherwise.

Aha, I didn't check the temp in my Power Manager. Here I see a temp of 32C. Still, fancontrol is reading 50C. Probably a misconfiguration?

By the way, when the fan is spinning up...it still doesn't go down anymore. Even when the system seems cool. And even when I configure Power Manager as 'adaptive' or 'low'.

Well, half-correct on the mis-configuration part. The TP FCU's temperature layout was originally designed around that of a T43 2668 Series Thinkpad. There should be around 9 temperature sensors in total; this number, and placement, however vary from Thinkpad to Thinkpad; even amongst the T4X Series Thinkpads. So what is indicated as the BAT(0x07c) or BAT(0x07e) temperature may not really be the temperature of the battery at all.

In this case, you could match up the temperature that the Power Manager is telling you (there is no reason to believe it is giving you incorrect data) with the TP FCU temp readings. Then you will have the temperature sensor that reads the battery temperature.
