After switching to Ubuntu my laptop is heating. I didn't have this problem when I had windows 7.I changed my CPU to "Powersave" mode but it is still heating and the fan is running at maximum speed.How can i make it to not be at max speed all the time?

My processor is Intel Pentium(R) CPU B960 @ 2.20GHz × 2 If this helps.

  • What brand and model number is your laptop? – Doug Smythies May 08 '15 at 14:51
  • Dell Inspiron N5110. The problem is that before i switched to ubuntu there was no heating. Now i have set the governor to powersave. I watch the CPU is showing no activity but the fan is running and the laptop keeps heating. Didn't have this problem with windows 7 – Ivaylo May 08 '15 at 16:12
  • Your CPU is a bit older, so its power saving features should be incorporated into the Linux kernel. It could be the GPU producing all the heat, though. What's the laptop's display adapter and which driver is it using? Please post the output of sudo lshw -class display. – David Foerster May 11 '15 at 09:08
