I'm using Lenovo Z370 laptop and I made a dual boot with Windows 7 and Ubuntu 13.10. I noticed that since I started using Ubuntu 13.10 my laptop frequently overheats and it powers off because of the excess heat. Any explanation? Thank you so much... Noland

It may be that your fans are being blocked - try going on more smooth surfaces in cool rooms. Don't put the laptop on smothering things like duvets. – Novine Nov 1 '13 at 12:44
I had this problem - the fans were blocked. Does it run fine in Windows/another OS? – whiskers75 Nov 1 '13 at 13:48

What happened: Overheating can be caused by several factors.

  1. You might be running CPU/GPU intensive programs that are very demanding on the hardware.
  2. There might be poor ventilation at your workspace.
  3. Worse case scenario, it might be a hardware problem that's causing this.

I took the liberty of looking up your laptop's specs, the specific model you're using does not have dedicated graphics. So that eliminates the possible cause of graphics card problems.

What you can do: Here's just some possible methods to solve your crisis.

  1. Install TLP, it's a wonderful program for increasing your laptop's power efficiency, which in turns increases the battery life and lowers the operating temperature. Copy/paste the following lines into the terminal while you're on Ubuntu. Search up 'Terminal' in the dash or press Ctrl + Alt + T.

    sudo add-apt-repository ppa:linrunner/tlp (adds the ppa so you can get future updates)

    sudo apt-get update (gets the latest version)

    sudo apt-get install tlp tlp-rdw smartmontools ethtool (installs TLP)

    sudo tlp start (starts TLP right away after its installed)

  2. Make sure your workspace is well ventilated, put your laptop over a surface that lets heat spread out faster.

  3. Buy a cooling fan pad to put under your laptop.

  4. If none of those worked to relive the heat problem, then its either caused by a problem with software or hardware, you should seek professional help from where you bought your laptop.

The Best choice to reduce the power and prevent to heat you pc just install the laptop tools it reduce the fan speed and save battery life.

sudo apt-get install laptop-mode-tools

or Either you can use TLP

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start

Note : Use only one on both of them.

hope it helps to you.

Does your laptop have Nvidia hybrid graphics? Did you install Bumblebee? If not then that may be the cause of overheating. Check this
