Overheat crash

English Hardware
#1

Hello,

As of yesterday, after a routine update, my laptop seems to crash due to overheating constantly. The computer shuts down and the very last entry on the screen states that CPU reached the thermal limit.

I am also noticing that the laptop runs much hotter than it used to, I am not entirely sure what could’ve happened because I never had this issue with this laptop before.

I would appreciate it if someone could suggest where to start looking for the cause.

OpenSuse 13.2 64 bit, KDE installed on Lenovo T410S M560-i5 dual, 8GB RAM, 120GB SSD

Are there any processes running amok?

If you can run top n a console or if you have ksysguard installed run that
and see if anything is taking all the CPU.

Does the fan start run or is it not?

Can you remember which updates were installed?

If there was a kernel update then try an earlier one from the grub boot
screen.

If the worst comes to the worst at the Grub screen you can always go back to
an earlier snapshot before the update and see if that makes a difference.

This is all presuming that it is a software fault, it could be hardware
maybe the fan has stopped?

Thank you for the reply,

1.It doesn’t seem CPU is being overworked. out of all 4 threads, I am reading on average of 10% (it’s an i5 dual core, with 4 thread)

  1. Fan is running, but i’m uncertain if it is running at full speed anymore. Previously I have set the fan to run at 100% at all times, but with Opensuse 13.2, I never bothered doing it because I never had heating issues since the installation until recently.
    I also need to mention that the fan seems to ALWAYS vent hot air now, even on idle. It wasn’t always like this.

  2. I cannot remember what has been installed, it seems that there is almost weekly updated to vbox nowdays and that’s the most prominent update.

I had overheating issues in the past when I used Linux Mint 17 and Ubuntu 14.04, I eventually found a way to have the fan running at 100% at all times, would you be able to run me through to set that?

I would not be surprised if it’s an hardware problem, (fan, or worn out thermal paste on core to cooler) considering that this laptop 5 years old and bought second handed.

Hi
Have you installed sensors and run sensors-detect, then the sensors command?

I did not have sensors installed, so I just did.

4000rpm is max on my fan, so it is running at almost at 100% currently. The laptop always ran at average of 50 deg. It seems normal, but I’m finding this a little bit odd. Aging parts maybe?

as you say that the CPU is not running at 100% that sounds very much like
you have a problem with the hardware.

It might just be that the fan or the sink on the chip is full of dust and
fluff and needs cleaning maybe even the intake is blocked as well, have seen
that on a few laptops that people actually use on their laps ( OMG! ) :wink:
and they suck up fluff off trousers et al.

Well as you say that the CPU is low then I would rule out an application
running amok.

Yeah I think you need to pick up that screwdriver and check, it could just
be that the heat sink has worked loose and needs to be tightened down again,
this happens a lot with all the heating and cooling. The holding down bolts
which are normally aided by tension springs can lose their springiness just
a quarter turn on each of the bolts might fix it for you. A dollop of thermal
paste would not hurt as well, a good spring clean is in order me thinks.

I did not think anybody needed to do that any more Malcom. I have not had
to use sensors-detect for about 3 years, all my installs* have
automagically picked up the sensors, maybe not the hard drive temp but CPU
and fans are there.

But you do have a valid point because the OP does state that he has had the
machine for 5 years and it was used when he got it so maybe the board has
one of those old Sis chipsets or something really obscure.

That is on a wide variety of boards and laptops, AMD and Intel especially,
but there again I could be wrong :wink: Which someone will definitely let me
know ( watch this space )…

Catch ya later

since I updated my Tumbleweed to Plasma 5 in my laptop, I have the same problem, but my PC doesn’t crash…
I had installed sensors, and now seems to be 7º-10º more than before, and fan is always running…

I’ll try if I can setup a previous kernel version…

No.

As your fan is venting hot air, it means that it is working correctly.
The problem is rather that something is generating a lot of heat, and
that the fan doesn’t speed up automatically.

What about graphics? Some graphics hardware have a tendency to overheat,
specially if they need their own fan and the driver doesn’t control it
right.

The graphics card is integrated to the core, I had another thread https://forums.opensuse.org/showthread.php/507324-Intel-integrated-Graphic-Card-Problem-exists-13-2KDE-but-not-on-13-1KDE

according to wolfi it is:
So this is a “Intel HD Graphics” or GMA HD card (not HD 3000 but a bit older), integrated into your Westmere (Arrandale) CPU.

so, I don’t think it needs a separate fan

On some they might do on others the gpu can share the CPU fan, it just all
depends on when and who manufactured the system, as yours is a bit old then
it may or may not have a fan but the chances that the intakes and vents may
still need a good cleaning.

Hot air coming out with the fan running flat out is definitely and indication
of something wrong internally and “WILL”! result in a fried motherboard.

Hot air indicates that the cooling system works. There is heat transfer.
If the CPU and cooler are not fixed properly, the cpu heats up but the
fins of the cooler do not, and thus the air flow remains cold.

Well, this isn’t comforting when the laptop has been cleaned, on a cooling pad, and left idle

Hi
How do you mean cleaned? Heatsink/Fan assembly removed, fan separated from cooler and any dust wad removed, new thermal compound applied?

If so, then it maybe the cooler assembly has developed a leak and the coolant gone… replacement required…

#16

I think that kernel issue is not involved with this problem!

I have check the temperatures with Plasma5 with Firefox, Thinderbird, Pidgin, and some other programs and this are the temperatures:

https://victorhckinthefreeworld.files.wordpress.com/2015/06/plasma_temp.png

And even sometime reached 71ºC !!

After that I installed another Desktop Environment. I go for Xfce. Same kernel, same applications opened, and temperature gone down 12ºC. With Xfce, the fan was quiet…

This is the screenshot

https://victorhckinthefreeworld.files.wordpress.com/2015/06/xfce_temp1.png

the problem is Plasma 5, but how can identify the application that make this?

Thnx

Hi
You should repost this in the Tumbleweed forum, not attach to an existing thread :wink:

Graphics rendering is way more intensive on plasma. Depending on your
hardware and driver, it is done by the cpu, in software, or in dedicated
hardware.

Well, the system remains to be running hot nowdays. I was able to get away from it using decent cooler but today the laptop crashed while I left my office while creating an ISO from a DVD.

I must say, that on 13.1, I did not have heating problem at all. I once literally generated 70 trillion random numbers without crashing.
