Laptop turns HOT

Hi all,
I am using openSUSE 12.1 on my laptop, HP dv2000. I notice that while I am using Firefox and watching Youtube, HDD and CPU turn very hot, and fan spins a lot, I can hear the sound of it.


linux-04rx:~ # hddtemp /dev/sda
/dev/sda: ST9250827AS: 59°C
linux-04rx:~ # sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +62.0°C  (crit = +120.0°C)
temp2:        +59.0°C  (crit = +120.0°C)



At normal, only Firefox, no flash video, I feel my laptop is a bit warmer than in Windows.

How to cool it down??
Thanks!

So I don’t know for sure, but it may have been a while since you purchased this laptop as new. Have you ever taken the laptop and blasted all of the dust out of it? If the answer is no or why, then its time for a cleaning, even for just 12 months of usage. Do not discount the need to clean out the dust from the internal Laptop heat sinks. If you have not done this before, I suggest you go to your local computer shop, or office supply or even large discount store and find a can or two of duster spray. I would buy two because the stuff gets real cold while being used and the supply pressure from a very cold can will drop dramatically. Once they warm up, the flow is back to normal and the stuff is usable on all electronic devices with a keyboard, heat sink or a fan of any sort. I remove the power adapter, remove the battery pack, get into a well light area and blast the spray into every vent hole on the laptop. If it has been a while since it was cleaned, be ready for a real surprise when the first dust is cleared out. Of course, it is always best to back up any irreplaceable data before taking any such action though this has never caused a problem I have heard of. It is always better to be safe than sorry however. Once complete, reattach the battery pack and plug back into your power adapter and power the laptop back into normal operation. Once you know the laptop is clean, other kernel power issues also can exist.

Now I found this a good read on kernel power consumption: GNU/Linux and openSUSE power management regressions - Blogs - openSUSE Forums

For setting your CPU power set from YaST have a look here: YaST Power Management - Control Your CPU Energy Usage How To & FAQ - Blogs - openSUSE Forums

You can install the latest kernel using this: http://forums.opensuse.org/blogs/jdmcdaniel3/s-k-c-suse-automated-kernel-compiler-version-2-50-34/

You can set your CPU speed using this: C.F.U. - CPU Frequency Utilitiy - Version 1.10 - For use with the cpufrequtils package - Blogs - openSUSE Forums

CPU speed and its energy usage is the number one heat generator in the main laptop circuit board area. Setting a slower speed will create less heat. Using the latest kernel like 3.4.4 might provide the most recent power control settings. But, clean out your laptop before you take any other action first.

Thank You,

With our recent heat wave, an additional caution is in order: that cold air
is really COLD and can easily result in condensation if you use long blasts
of air. In high humidity areas, that moisture can result in potentially
fatal (to the components) amounts of moisture, especially if the
accumulation of gunk is high. If you have to do serious blasting, pull the
battery and do it with the absolute minimum power present in the device.

Best results will be with short bursts of air. Around here, relative
humidity is usually 10% or below but my memories of Austin in the summer are
that the humidty frequently matches the temperature…

Thanks for your suggestion!
I have been using laptop for 3 years without cleaning once. I hesitate about cleaning the laptop because its model structure is not easy to assembly and I have not found someone skillful enough to do the job.
I think this is time to do it! :\

WAIT! if you can’t remove the battery pack without using a screwdriver
do NOT take your laptop apart!!!

taking your machine apart is not recommended by any of the previous
posters. (some machines have a really easy way to slide the battery out
without using any tools! some do not…)

instead, go to the makers web site and learn what they say about heat,
and cleaning…if they they have instructions specific to your machine,
then follow them…if nothing then:

ONLY clean by blowingair* through the cooling vents (probably on the
sides or bottom)

the others have talked about using canned air, which is delivered under
high pressure and a thin stream…if you use that TAKE CAUTION because
you can do damage with too much cooling, or two fast a stream…

the too fast stream can ruin the bearings of fan(s) inside the case…
too much cooling can cause water to form inside the case…

personally, i just use a vacuum cleaner…i start with a small brush
attachment and suck what i can out of the keyboard, the i pull air
through the machine (and into the vac) from the vent(s)…

then i put on the concentrator attachment (which speeds up the flow) and
suck with it…

then, i insert the hose in the vac’s exhaust outlet and therefore can
blow air out, and through the laptop…

canned air is quicker, probably a lot more thorough BUT it introduces
some risks…

and, if after cleaning the machine is just as loud/hot–post again,
maybe all you need is a software tweak or two, as already described.

let me repeat: do NOT disassemble your machine unless you don’t need it
again, ever. and, be sure an make a copy to an off machine safe place of
everything on the machine you might want later (like: music, movies,
photos, letter/emails to/from friends, homework, tax records, business
records, etc etc etc etc)

I will NOT disassemble my machine :slight_smile: I can see that is extremely risky, so I will take the easier method, I will try the vacuum cleaner.
Thank you! :slight_smile:

and, don’t overlook the distinct possibility that your system is clean
enough, and you just need to tweak the software’s controls of things
like cpu and/or fan speed…

by the way, in some cases just turning off all the fancy desktop effects
is enough to drop the computing needs down to a more reasonable
level–and you will then find less fan noise, less heat, longer battery
life AND an overall snappier desktop!

and, STILL be miles ahead of the so called competition in terms of
modernity of presentation.

This is not a problem of your laptop. This is a problem of openSUSE 12.1 with laptops. My lenovo runs with minimum temperature of 69 degrees and presents peaks of 99 C with security shutdowns. This is a known problems and bugs have been reported in bugzilla. Albeit a solution does not seem to have arisen.
You can clean as much as you want. But generally the problem will come up with indexing of nepomuk, with the acpi no working correctly (look in you log to find the following:

If you find these kinds of statement, this is a bug, not your ventilator.

All the comments about cleaning your machine are of course absolutely
valid. So please do it as you already plan to do.

When you have done it and notice that it did not help or did not help to
lower the temperature to a level which is acceptable, I can only throw
in my experience with my ThinkPad here.

I noticed it ran hot with the standard kernel for 12.1 (sorry that I do
not have the exact numbers here that was after I bought it 2 months ago).
After some investigations about running processes or whatever else that
causes it I updated the kernel to 3.4 from
http://download.opensuse.org/repositories/Kernel:/stable/standard/
and the problem disappeared immediately (roughly 5° C and more less in
my case of top off my head).
Current temperatures with 3.4 are


Physical id 0:  +46.0°C  (high = +80.0°C, crit = +85.0°C)
Core 0:         +46.0°C  (high = +80.0°C, crit = +85.0°C)
Core 1:         +42.0°C  (high = +80.0°C, crit = +85.0°C)

Also the battery lifetime increased by more than an hour.

To switch the kernel add the repository and switch with yast the
installed kernel to the one from that repository, then reboot.

Warning: Please keep in mind that if you use any proprietary drivers
like ATI or Nvidia that you need to reinstall them manually.

What a pitty Martin. Does not work for me (Lenovo Thinkpad X201i). When using the kernel you indicated (I am having a LUKS encrypted swap and home) I am getting “inut output error” from libcrypt and cannot access home and swap.
So back to the “heatvave kernel”. Hopefully components will live long enough for the new (maybe working 12.2 version in September).

Sad to hear that (I use no encryption on the machine, so I cannot help
with that).
You could run a live image for the current 12.2 beta to check if that
problem exists still in 12.2 which has the 3.4 kernel and also to see if
your heat problem disappears with that.
Because if the crypt problem you mention is also in 12.2 and nobody
tests that and reports it it will also be in the final unless they solve
it by accident.

yep, a real good way to insure the problem is not fixed in 12.2 is to
wait after it is released in september to test it.

Nevertheless, in the particular case mentioned by the OP, his is one of a series of HP laptops very prone to overheating after a couple of years, and he does mention that he’s had it for three years without cleaning it. For either of those reasons, IMHO, I’d recommend the cleaning in any case… even if software issues are found to be a factor.

If the problem still exists after cleaning out the dust and addressing any 12.1 related issues I’d recommend replacing the thermal paste on the CPU (& GPU if separate). I’ve seen many, many cases where the OEM had done a poor job of putting the paste on during original assembly and or used poor quality paste. After two or three years the paste dries out and cracks or shrinks, and overheating will result.

Most users are uncomfortable undertaking that repair, but there are some good illustrated step by step tutorials on the web. If that’s too scary still you can get the job done quite quickly and inexpensively at any repair shop that services laptops. I don’t favor the big box stores’ service centers… too slow, too expensive and marginally competent. Most towns have one or more small “Mom & Pop” shops that do that PC service work. Ask around and find one your neighbors recommend. As an added benefit the tech will be able to do a much more thorough job of cleaning the PC while he’s got it open.

Hold on.

Even if the load goes up due to bad software, any computer must be able to
cope with a fully loaded, 100% CPU and GPU. You can remove those bad
elements in software, but if you run, for example, a video re-codification
that pushes the CPU up for hours, the hardware cooling elements must be
able to cope with that, user induced, load. Else, that hardware is badly
designed or in bad state.

Of course, if the hardware delegates things like fan control to the
software, that software must do that controlling adequately.

Hm, I have upgraded to new kernel, 3.4
However, it still becomes extremely hot when I play videos on Youtube.

So can it be problem from Intel integrated card??
I used a small blower tool from my laptop cleaning pack to blow into a ven hole. Nothing went out. Maybe the air flow is not strong enough. I have tried a vacuum, however, it does not have “blow” function, and I have not found any place near my house selling compressed air can.

How can I open this file??

either you install the log viewer (if you use kde, it is in the repos) or you open a terminal and:

su -
cat /var/log/messages

For you convenience and your personal enjoyment:

With the time you will love the possibilities the command line gives (without me wanting to claim that it is always better then GUI driven solutions. But it comes handy to know more.

If you don’t like ‘cat’, there is also ‘dog’. If the file is long, the
traditional way is to pipe it through ‘more’, but I prefer to use ‘less’,
which is more than ‘more’ :slight_smile:

I always said it “less is more or less like more”. :slight_smile:

For watching a logfile, though, tail -f is preferred (at least I do). I
tap enter a couple of times when I’m ready to start doing whatever it is
that I want to see the log output from, putting a couple of blank lines
in the tail output (makes a good easy-to-find marker).
