Description biosed 2010-06-21 09:10:02 UTC
The problem started after leaving the pc off for 1 month, since there when it gets hot, around 80C degrees it just shuts off, but it used to work much hotter and very well. It used to work well around 90C where the fan speeds up to 100%.

The same happens in gentoo, ubuntu, arch, mandriva, opensuse and vista.
I used to use gentoo but compiling got too hot and I cannot use any more, ubuntu works better that any other system(at least for more time), but it freezes too whe it gets too hot.

The big difference I can see between before the problem and after is that the fan used to be very noisy when it got hot, but now is like fan is no working faster ever.
Of course, I cannot change trip points or fan speeds.
I tried fan options in bios (always on/off) and it makes not change.

I already downgrade and update BIOS from hp web page but nothing changed.



System information:

HP pavilion 1245es

I attach results from firmwarekit live cd

so the problem pops up without any software changes, i.e. with the same kernel?

If it's caused by the non-working fan, the symptom should be temperature increases quickly and shutdown soon.

the problem also exists in Vista?
can you please clean the fan and the ventilation opening of the laptop?
we have similar bug report before, and it's because the ventilation opening is jamed...

BTW: please attach the output of "grep . /sys/class/thermal/*/*"

Hi!

Yes, is with same kernels, in gentoo I had kernels 2.6.32 2.6.33 and 2.6.34
I already uninstalled gentoo and I tried with many systems, every system is the same problem.
In Vista is exactly the same problem.

grep . /sys/class/thermal/*/*
/sys/class/thermal/cooling_device0/cur_state:0
/sys/class/thermal/cooling_device0/max_state:10
/sys/class/thermal/cooling_device0/type:Processor
/sys/class/thermal/cooling_device1/cur_state:0
/sys/class/thermal/cooling_device1/max_state:3
/sys/class/thermal/cooling_device1/type:Processor
/sys/class/thermal/cooling_device2/cur_state:6
/sys/class/thermal/cooling_device2/max_state:10
/sys/class/thermal/cooling_device2/type:LCD


as you can see there is some thermal LCD information?, WTF!

There is no  /proc/acpi/thermal_zone/ or /proc/acpi/fan information, but if I reboot with acpi_osi="Linux" I get strange vlues.. I will reboot now and Ill paste it.

Thanks for the help!
Comment 4 biosed 2010-06-23 09:26:37 UTC
ok,

Here I have some more info:

with acpi_osi="Linux" I get some trip points:

 cat /proc/acpi/thermal_zone/THRM/*
<setting not supported>
<polling disabled>
state:                   ok
temperature:             59 C
critical (S5):           100 C
hot (S4):                -273 C
passive:                 95 C: tc1=2 tc2=3 tsp=30 devices=CPU0 CPU1 

as you can see this "(S4):-273 C" is very strange.

In vista and gentoo I had thermal sensors and before the problem temperatures used to arrive to 90 or 95 and it did not freeze, now it never goes more than 80.

The fan is really clean, I already open the computer and even I changed the thermal sink in the cpu and gpu.

I tried everything I could.

well. it seems that there is not fan device on this laptop.

please attach the acpidump output.

I google this issue just now and found this is a common issue for HP laptops.
http://forums.pcworld.com/index.php?/topic/89114-hp-overheating-issues/

I'm afraid there is nothing we can do there as this is not a Linux kernel issue.
BTW, I suggest you to get a cooling pad, I'm using one for my HP laptop currently as well...
Comment 8 biosed 2010-06-30 08:23:51 UTC
ok, thanks for the help

I know about hp amd64 cooling problems, but this is a little different, it used to work well, hot, but well, and one day the fan did not arrive at 100%. It is like bios values are changed, because I noticed too that there is no bluetooth anymore and many strange things.

right now is with a DIY cooling pad of 220V!

I can do everything except compiling gentoo(I just love gentoo), it gets too hot and crash, ok , i can put the CPU in powersave, but it takes so long...
And things does not work so good in ubuntu as in gentoo.

It is a pity that I cannot use this machine at 100% becaouse a fan.

good luck
