Toshiba i5 Overheating using Kubuntu 13.04

mauripeta · 07-01-2013, 08:52 AM

Hello guys,

Last week I bought a new laptop (Toshiba Satellite L845-SP4304LA), this one comes with Windows 8. So I installed Ubuntu 13.04 with KDE desktop taking into account that I had to change the default UEFI BIOS for the CMS BIOS.

The problem is that my laptop now overheats and I don't know why, I'm trying to find any app that allows me to check the temperature of my components (e.g. GPU, HDD, CPU, etc). Haven't find it yet.

I'm starting to believe that Ubuntu 13.04 don't have any control over the acpi. Can you help me please?

Thank you for your time!

Mauricio

You could be right. Toshiba laptops with the Insyde H20 have been known to have this problem. Toshiba is evidently uninterested in the problem. I found that allowing mine to overheat, and then power it up right away, allowing the fans to come on while the bootloader is running would cause the fans to stay always on, keeping it cool until the next reboot. Not saying this is good practice, mind you...

toshiba did not do a very good job with there heatsink and they did not in my opinion apply enough thermal compound my suggestion would be to get Arctic Silver 5 Polysynthetic Silver Thermal Compound Paste its around 8 to 10 usd and it worked for me good luck and i hope this works for you

If you have a dedicated GPU and don't use Ubuntu for any graphical intensive processing then you could disable the graphics driver, it'll cause the system to use the integrated graphics chip and will surely provide some relief from your temp woes.
I disabled the nouveau driver(open source driver for Nvidia cards) in my fedora 18 and now it runs ~10-15 degrees cooler. For temperature monitoring you can give lm_sensors a try.

**If it hasn't been 30 days since you purchased that laptop;If I were you I'd take it back**

There is a CPU Frequency Monitoring Application-

I used this application with Voyager 12.04 which is Xubuntu based and it worked great.

Code:

sudo apt-get install cpufrequtils sysfutils

You will have to edit this file:
/etc/sysfs.conf
And add this line for each core:

Code:

devices/system/cpu/cpu0/cpufreq/scaling_governor = performance

I just spent the last 4 weeks with taking an old (2008) Toshiba laptop apart and replaced the fan.
The heat sink were pretty nasty so I cleaned it up and applied fresh compound-
From what I read they are notorious for overheating.
