HP G60-249WM Notebook overheats (on lenny)

[Brian C. Wells]

Hi.  My HP G60-249WM Notebook's CPU is overheating, to the point that it
shuts itself off, whenever I use any CPU-intensive game such as glchess
(in the gnome-games package) or the non-free game sauerbraten.  I also
use the non-free nvidia-glx for accelerated graphics, and have the
laptop software packages installed, in case that matters.

It used to do this when I watched youtube videos too, so I bought a
cooling pad, and that fixed that problem; but with these games it's
happening even with that.  I've tried using spacers to increase the
ventilation, tried using it on my lap with the part that feels warm
hanging out in thin air, even installed computertemp to get objective
evidence that the CPU's temperature is increasing to dangerous levels
(>95 deg. Celsius).  As soon as I start a game, it rises, and as soon as
I stop it it falls.

I haven't filed a bug report because this seems like a symptom of a more
general problem.  I'm not sure whether software (e.g. acpi/apm config)
or hardware is to blame, let alone which software package.  I would
appreciate any advice.

Thanks,
Brian

Sounds like a hardware problem; most likely a fan problem: either it's
clogged, or it's broken, or something.

I don't -think- it's a fan problem.  It seems to be blowing plenty of
hot air out, and I can't see or blow out any obvious clogs w/o opening
the case.  To me, it seems more like a design defect; this laptop has
had this kind of problem ever since I got it, which wasn't long ago.

Like you say, it's probably a hardware problem, but HP might say it's
all Linux's fault for not using some proprietary interface.  (Then
again, I haven't asked them.  They might agree with you.)

In any case, thanks for reminding me to check the fan more closely.

I have a G70, which runs hot.  I used a vacuum cleaner and sucked out
all the openings I could find, which cooled it some.  Then I also got
a Xpad-slim.  It's running at 40.0C right now.  It goes up when I'm
doing some heavy processing.  Once in a while FireFox 3.0 pushes the
temp up, but I can watch streaming movies or YouTube with no
problems, although the temp does rise some.

My understanding is that HPs are notorious for high temps.  :(((

IMHE, many HP laptops suffer from the same syndrome (just look up some
previous messages on this very same list). Apparently, there are some
aggressive powersaving quirks/tricks which are not yet present in
Linux, but are implemented in Windows. I suspect some industry secrets
only get revealed through closed agreements, and never released to the
FLOSS community. My HP laptop, for example, *never once* overheated in
the few months it had Windows XP on. The other factor (besides these
quirks) must be some runaway and/or underoptimized applications in
Linux. Currently, I'm facing severe overheating problems in Lenny on
account of xulrunner-stub, whose CPU usage frequently jumps up to 60 or
70%, quickly heating up my laptop.

My advice for your particular situation would be the following:
1) I vaguely recall hearing of a Nvidia-specific package for fine-
tuning certain parameters of the Nvidia driver. It's probably related
to the proprietary Nvidia driver and it might not even be obtainable in
the Debian repositories, but it might potentially aid you in the issue
at hand; so, as always, Google is your best friend;
2) Facing the same problem, I made a script to toggle the powersave/
ondemand CPU governors, so every time xulrunner-stub goes berserk, I
press Fn-F11 (which I bound to the script) and my CPU frequency goes
from 2 GHz to 800 MHz, cooling down the laptop in no time;
3) I've also found out that nothing helps as much as regular cleaning
all the orifices of my laptop with an industrial-grade vacuum cleaner.
4) And, yes, *no two* graphics drivers behave the same with regard to
overheating; IMHE, the proprietary fglrx ATI drivers have less
overheating problems than the radeon and the vesa/framebuffer drivers.

There, my 2 euro cents (as a matter of fact, is there a key combination
for obtaining the euro cent sign, as there is AltGr-E for €?)

Was that an ordinary floor vacuum cleaner, or one of those keyboard
cleaners?  I've never used an ordinary vacuum on a computer... I'm
worried that particles from the floor might fall into the PC.

Without using a vacuum yet, but with a cooler, mine is running at 54C
right now.  If I can get it down to 40C, that just might make the
difference.  So thanks for reminding me about the possibility.

Great. :S  I'll keep that in mind next time.

I see you were having even worse problems with this.  :(

I had the same kind of suspicion.

This laptop came with Vista installed, but I immediately replaced it
with Debian.  So I don't have a Windows trial period to compare with.

When I run glchess on my computer, the gnuchess engine actually goes to
100% (according to top), and the temperature goes up quite quickly.
sauerbraten only seems to need 60% or so, and doesn't overheat as
quickly (probably because the GPU is doing the graphics acceleration).

The package is called nvidia-settings, in the contrib section, and I
already have it installed.  But I don't know which settings, if any,
might help in this situation.

Wow.  Except for the part about writing a script, I have no idea about
how to do that.  Can you attach a copy of your script to the email (and
does Debian's list server forward attachments?) or can you upload the
script to a pastebin website or something?  That would at least give me
an idea of what commands I would need to use.

I'll definitely give that a try, like the earlier post suggested.  An
"industrial-grade vacuum cleaner" sounds like a floor-cleaning model,
so the same concern comes to mind about particles in the vacuum, though.

Hmm.  Maybe they have some of that secret technology you talked about.

Wish I could help with that.  Unfortunately, I'm in the US, where we know
very little about AltGr keys (or their combinations).

It was a regular floor vacuum cleaner.  I'm not sure how crud from
the floor might fall into the computer since the suction is going the
other direction.

Well, the script is quite simple, it only works in Gnome (a
more system-wide script would have to be run as superuser and I just
couldn't be bothered to type in my root password every time I wanted to
change CPU governor):

<script to copy/paste:>

#!/bin/bash

state=`gconftool --get /apps/gnome-power-manager/cpufreq/policy_ac |
cut -d\  -f1`

if [ $state == "ondemand" ]; then
  countdown=`echo {99..1}`
  gconftool --type string --set /apps/gnome-power-manager/cpufreq/
policy_ac "powersave"
  gconftool --type int --set /apps/gnome-power-manager/backlight/
brightness_ac "50"
else
  countdown=`echo {1..99}`
  gconftool --type string --set /apps/gnome-power-manager/cpufreq/
policy_ac "ondemand"
  gconftool --type int --set /apps/gnome-power-manager/backlight/
brightness_ac "95"
fi

state=`gconftool --get /apps/gnome-power-manager/cpufreq/policy_ac |
cut -d\  -f1`

for i in $countdown; do echo $i; sleep 0.01; echo "#";done|zenity --
progress --auto-close --title=$state
echo CPU governor switched to $state.

</end of script to copy/paste>

The script is self-explanatory. You save it under a name of your choice
(say, CPU_governor_toggle), set its executable bit, ... you know the
drill.

This is what sudo is for - one just configures it to allow anyone to
run it as root.  Another possibility is to make it suid root.  I
suppose, though, that either of these techniques might be security
risks, if the script is buggy / insufficiently secure and a malicious
user manages to run it.

Which of the two methods is considered less of a security hazard? Can
either of them be made secure in a relatively simple way?

Well, I'm no security guru, but the fundamental problem here applies to
both of them: if there's any way that the script can be manipulated to
run arbitrary code, or give the user access to a shell, then the game's
over ...

Or only users from a particular group to run it only after providing their
password; sudo is *very* flexible.  It can do nearly everything su, suid, and
sgid can so, plus some.

> Another possibility is to make it suid root.

Suid scripts don't work unless your shell/interpreter is also suid.  This is
usually a bad idea.

It looks like the only input the script takes is the output of gconftool --get
of a specific key.  Under the assumption that an attacker can set the "$state"
variable to whatever they want, they can make the script fail, but I don't
think they can do anything malicious.  I'm not a security expert by any means.

Thanks for the information.  I didn't know that, but that's because I
never play with such dangerous things as the suid bit ;)

I did have to read a few man and gnome help pages to understand what the
script does, but as scripts go, yes it's fairly straightforward (and
I've already made a few modifications to suit my tastes).  Thank you for
showing me this.  I didn't realize gnome-power-manager had cpufreq
settings.  One more reason to explore gconf-editor.

I also want to apologize for taking 4 days to respond.  I thought it
would be best to wait until I had tried using the vacuum, but still
haven't gotten around to it.  I don't have carpeted floors where I live,
so I don't have easy access to one; but I'll try to borrow one tomorrow
and let you know what happens.

Yes, it has an NVIDIA GeForce 8200M.

I'd wager that's the problem. I've seen/experienced this on three
laptops now, and there have seen similar reports on this list which
I strongly suspect were caused by the card's driver.

I've not fully diagnosed it, though, so it remains just a very strong
suspicion.

The way I test for the problem is to run glxgears, gradually increase
the size of the window, and at some point the cpu will max, the frame
rates will drop through the floor, and fans will kick in. Eventually the
machine will overheat and shutdown.

Other problematic apps are Skype and video (beyond a certain window
size) via browser or not. All symptomatic of a video driver issue.

My workaround is to fix and drop the cpu speed. I run a gnome widget
that makes this simple, and indicates when the cpu has maxed.

I raised a bug against this after I installed Jaunty, because that's
where the problem started, but I've not had any useful feedback.

Vacuuming brought the idle temperature down by 5C.  sauerbraten now runs
great at about 80C, but glchess/gnuchess still gets up to 95C or more!
I think this is caused by an already-reported bug in gnuchess [1] that
uses 100% CPU when run under an X interface.  (Just like the reporter,
I don't have the problem when I use gnuchess from the command line.)

Unfortunately, setting gconf /apps/gnome-power-manager/cpufreq/policy_ac
to "powersave" doesn't seem to eliminate the problem, either.  I guess
I'll just have to wait until the bug is fixed to play Chess normally. :(

You might look to see where the vents are located. I have my
notebook up on spacers so that vents underside can get more
airflow.
