TOSHIBA Laptop overheating - Hardware failure - (SOLVED)

Postby Dardarian on Mon Apr 06, 2009 10:12 pm

I am running Mint 6 (Felicia) on a Toshiba Satellite SP100 (intel centrino duo).
NVIDIA video card running version 177 accelerated graphics driver (recommended)
Pretty much out of the box with Gnome.
Dual boot with XP
Shared DATA partition (NFTS) D:

I recently discovered Compiz and spent some time playing with its settings. I noted that all the bells and whistles slowed the system down and so went back to bare settings.

Now I do not know if this is connected but my Laptop is now running seriously HOT. So much so that it has a hot smell from the exhaust, becomes too hot to touch and eventually switches itself off.
The fan is running normally and this is the first time I have noticed this since install.

I have been reading a few posts on the forum but nothing seems to fit and I need to turn my system off in order to let it cool down!

I would really appreciate any help here I do not want to fry my hardware.
Looking forward to your response.

Yours worriedly,
David

Hi there
I installed computertemp via the package manager and have restarted.
This may be a total Noob thing to say but I cannot find the launch for the applet and if I type the command into a terminal:

user@SP100MINT ~ $ computertemp
bash: computertemp: command not found
user@SP100MINT ~ $ sudo su root
[sudo] password for user:
SP100MINT user # computertemp
bash: computertemp: command not found
SP100MINT user #

However, looking at my nvidia X server setting I can see that the GPU core temp is 115deg (spiking to 125deg) and the ambient temp around it is 95deg (spiking to 105deg)!!

Haven't found any other way of checking CPU temp yet

Cheers

hi, you may need to change your Heat-sink and fan but, it's hard to say.
check to make sure your fan is working.

in the mean time.. here
http://www.mytechopinion.com/2008/10/so ... oesnt.html

The Link I gave you is good for summer so if things do start heating up, your Laptop will be ok or should be.


this link will help your Laptop from over heating on you or die on you... which ever comes first!

serial Number and Model number would be nice to this way I can get more information about your Laptop.
possibilities of a faulty motherboard, bad memory, bad exhaust for the laptop, or bad heat-sink and battery



Let me know and me or someone else will take the next step to do the Job.

1. I would double check to make sure the fan is running and that the cooling vanes/fins are free of dust. Every once in a while I open up my laptop and clean it out... and I see an immediate drop in temperatures... sometimes by more than 10 degrees C.

2. I would throttle (under clock) processor frequencies until the problem gets fixed. This will help keep temps down and avoid frying your hardware. My CPU frequency can be controlled with the tools in the package 'cpufrequtils'. There may be something similar for your Nvidia card. Google it.

3. Try disabling the NVidia non-free driver and using the open source one. Does this prevent the over heating? Does it overheat in Windows?

while your doing checking the heat-sink and fan... see if you have a friend that has a laptop and borrow his battery.... and put that in your laptop instead.

most battery for laptop should work but still check to see what type you have inside your laptop and hope you you have the same one as your friend. This way you don't have to spend money for nothing before buying.

Thanks so much Guys - I will try these things and get back to you - At the moment I have to limit run time to stop things melting down!
I have cleaned out the case of dust recently, never run it off a flat / hard surface and the fan runs OK

Toshiba Satellite SP100
PSPA6A-01J017

Appreciate the help.

Will report back soon.

Yours Aye

Re: TOSHIBA Laptop overheating - Hardware failure problem solved

Sorry it has been a long time since I posted but much has happened.
I tried everything suggested but nothing worked.
I eventually took resotred my laptop to WIN XP and took it to be serviced.
It was discovered that my laptop has a faulty temperature control module!!
This is being replaced - hopefully this will solve the problem!

Many thanks for all your help.

Regards
David
