CPU locks up and temperature increases

Asked by Brian Marine on 2012-11-16

Yesterday while i was using my laptop with two chromium web browsers, skype, and banshee media player running my cpu got to about 73% and wouldnt decrease even after i closed everything, the parts of my laptop got to about 86C at the max, the only thing thast worked was to suspend it and let it cool down, then the cpu was fine again. The only modifications i made to ubuntu was the swappiness, used bleachbit and have zram.

im runing those same programs right now and if i dont touch anything the cpu gets down to 9%, also i dont know if this will help but i have intel centrino vpro 2 dual core that gets 2.24 ghz and i have 3 gigs of ram and an nvidia Quadro NVS 150M but my laptop was bought of ebay used and i have had it for about 2 or 3 years and it previously had windows vista buisness 32 bit.

also sorry for the constant updates but i forgot to mention i already have a laptop cooling fan, it is conected to a four port usb hub

again sorry for the constant upload of more info, i also must say that right now i have my nvidia proprietary driver set to adaptive performance mode and i installed jupiter and set that to power saver. to avoid overheating

what is the make and model of the system????

Brian Marine (crysisfreak7) said : #6

the laptop= Toshiba tecra m10
cpu= intel centrino vpro 2 dual core
gpu= nvidia Quadro NVS 150M
ram= 3 gigs / 2 chips = 1.5 gig chips
as for other info
ubuntu version 12.10 quantal quetzal 32 bit
6 gigs swap space though for some reason it wont auto mount on boot up and it still says i have 1.5 gigs swap
bios= toshiba (of course)

Can you give the output of:

sudo lshw -C display


6Gb swap is a bit excessive. You only need about 3.3Gb but you'll probably have enough space to not care

yeah i havent noticed the swap partition ever being used so i just set swappiness to 1 just incase it does need to be used one day

Good call. What is the output of:

dpkg -l | grep nvidia

rc libkwinnvidiahack4 4:4.9.2-0ubuntu2.1 i386 library used by nvidia cards for the KDE window manager
rc nvidia-173 173.14.35-0ubuntu0.2 i386 NVIDIA binary Xorg driver, kernel module and VDPAU library

ii nvidia-settings 304.51-0ubuntu2 i386 Tool for configuring the NVIDIA graphics driver

ok let's clean this up:

sudo dpkg -P libkwinnvidiahack4 nvidia-173

Do you use the Cg toolkits you have installed?

Brian Marine (crysisfreak7) said : #13

no i dont program anything that would require it so no. also is enabling fxaa in the antialiasing settings going to speed things up?

Brian Marine (crysisfreak7) said : #14

the closest thing i do to programing is 3d modeling using blender

sudo apt-get --purge remove nvidia-cg-dev:i386 nvidia-cg-toolkit nvidia-current nvidia-settings

sudo apt-get --purge autoremove

Reboot then reinstall the driver. May help
