Temp Chart Picture

Though CPU usage is minimal, yet the core temperature is greater than 54°C (129°F).

Another issue is if I start the browser core temperature that would reach 60°C (140°F), the CPU usage would ascend to 100%.

  • Welcome to Ask Ubuntu! How old is this thing? Is there any chance that it’s full of dust, that the internal cooling fans broke (can you hear them running?) or that the thermal conduction paste or pad has degraded (e. g. due to long term exposure to very dry or very humid environments)? Can you please install and run lm-sensors and add its output to your question (use the edit link below it to edit it)? Thanks. – David Foerster Sep 23 at 8:22
  • @David Foerster, dust was not there. may be past is old. notepc is 5 yrs old. fan is working good. conduction paste may be last option i need to check – nitturi shiva Sep 23 at 12:52
  • Another thing to look for are BIOS updates from the manufacturer to deal with firmware issues that affect thermal control as well as the intel-microcode package. – David Foerster Sep 23 at 14:06
  • You can find BIOS updates at support.ts.fujitsu.com/IndexDownload.asp if you search for your product model “AH502“ and select OS-independent downloads. You’ll need a working Windows installation or a bootable DOS environment (FreeDOS should work too) though. – David Foerster Sep 23 at 14:32
  • Thanks David Foerster.,changed metal paste, still heating issue persist. my bad is I have not installed the windows for BIOS modification :(...need to hack a lot. – nitturi shiva Sep 24 at 2:31
