I use an HP laptop "Compaq 6710b" (with the original hard drive being replaced by an SSD).
Kernel vmlinuz-3.17-2.slh.7-aptosid-amd64 was the last kernel version that has been running perfectly until today.
With all later kernel versions I have had the problem that the fan is permanently running. Although this is better than a non-working fan, the fan is loud and annoying, especially since I want to use this laptop mainly for listening to music.
The "sensors" command from the lm-sensors package shows an interesting difference:
With kernel 3.17.2:
Code:
acpitz-virtual-0
Adapter: Virtual device
temp1: +50.0°C (crit = +256.0°C)
temp2: +48.0°C (crit = +108.0°C)
temp3: +42.0°C (crit = +105.0°C)
temp4: +25.5°C (crit = +108.0°C)
temp5: +20.0°C (crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +50.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +50.0°C (high = +100.0°C, crit = +100.0°C)
With kernel vmlinuz-4.1.0-2.slh.2-aptosid-amd64:
Code:
acpitz-virtual-0
Adapter: Virtual device
temp1: +51.0°C (crit = +256.0°C)
temp2: +46.0°C (crit = +108.0°C)
temp3: +41.0°C (crit = +105.0°C)
temp4: +26.0°C (crit = +108.0°C)
temp5: +100.0°C (crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +47.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +49.0°C (high = +100.0°C, crit = +100.0°C)
So, obviously "temp5" is close to its limit, so that this is maybe an explanation for the fan running... However, I have no idea what "temp5" is and why it depends on the kernel version (and what to do to prevent it from going up)...
(Both "sensors" commands entered directly after boot-up into the usual framebuffer terminals, i.e. no X11 graphic running.)
By the way, all process checks (ps, top) show no difference between the kernel versions, so that I'd assume the problem is rather with the kernel (or some temperature measurement problem with the "coretemp" module?)
Any ideas?
Thanks for your time and your suggestions!  |
