HP Pavilion dv 6730ew - Nvidia Geforce 8400M GS - fan speed

Hi,

After upgrade few packages:
kernel26 2.6.29.4-1
kernel26-firmware 2.6.29-1
nvidia 180.51-1
nvidia-utils 180.51-1

I observed strange work of fans. After start system, fans are working on full speed. This state persist for few minutes in spite of temperature of CPU and GPU is normal.

After that fans work normal (I think ) - they accelerate when load is big and slow down after.
UPDATE: I don't think that fans work normal. They work too fast and too ofteen without seriously reason.

With older version of this packages (kernel26-2.6.29.4-1 kernel26-firmware-2.6.29-1 nvidia-180.51-1 nvidia-utils-180.51-1) everything is normal, that's mean - fans doesn't start after boot, only during bigger load.

Have anyone similar observation?

I don't have the fan problem, but there are a lot of things that stop working with latest kernel for my hp dv6744eo. Wifi card starts up with errors, no sound card detected, doing some guessing, rc.local won't be read any more and a lot of other peculiarities especially as to hardware. I have reverted to 2.6.28 kernel.

I guess hp laptops are not well supported on linux as they are marketed as windows compatible.

One other thing that might be causing problems is that the acpi-dsdt-initramfs-patch are now gone from archlinux kernels.

It is alwas hard to buy a linux compatible laptop.

I'm also using an HP laptop and so far I haven't noticed anything broken/abnormal since the latest update.

Well, hp and hp - almost every hp laptop has something different from the other. I have for instance some conexant (Hermosa) chipset on the sound card - it has never worked correctly, but for my needs it is acceptable.

Wifi atheros until recently did not work with ath5k for my peculiar model of hp - card reader, fingerprint etc. I haven't even bothered as that is external haberdashery that I don't need or that can be fixed in other ways like usb cable etc.

But with latest kernel even ath5k is giving problems, reverting to older kernel fixes it, why I presume it has something to do with the new kernel or with some other packages having to be rebuilt against the new kernel.

I love my hp, but for the moment it needs too much attention for me to be interested in looking for known and unknown problems with this or that as hp doesn't use standard and own parts, but asembles their laptops with god knows what cheap parts from model to model with only "windows compatible" as guide lines.

I see, I have lucky, becouse my HP have in most Intel devices. Only fingerprint doesn't work but I really don't need it.

Back to my fan-problem - maybe "it's not bug, it's a feature"?
I have new observations. Probably that's not problem with acpi/kernel etc but with nvidia drivers. Always after wake up or start X, my graphic card switch on to 2 performance level and temperature of GPU growing to about 60 degrees (normal is about 50).

Why nvidia needs to switch to 2 level after wake up or start X?

------------- UPDATE:

Now, I'm sure that nvidia driver is guilty.
With Nvidia 180.18.14, GPU is still working on the fastest performance level so temperature grows and fan starts. Whatever I set in xorg.conf, performance level is always 2.

With nvidia 180.51 everything is normal. GPU switch level if it need or hold level that I set in xorg.conf

I have a GeForce 8400M GS - Have somebody this same card?

Hi, becouse new drivers became (185.18.31) into arch repo I'd like to describe new problems.
Now - GPU is normal switching between performance level - great.
Fun works normal during big load - great^2

but... Always after start X - fun works with full speed for about 5 minutes. After that - works fine.

Maybe you should give lm-sensors a try?

lm_sensors show mi only info about cpu temperature - I'm not sure that is fault my configuration or maybe my laptop isn't supported.
