Why is my notebook very hot? I installed the driver for Nvidia, but nothing changed. Ubuntu has a temperature of 40-50C with the driver and 70-80C without the driver. Terminal:
sergey@sergey-Aspire-5750G:~$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +82.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +82.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +81.0°C (high = +86.0°C, crit = +100.0°C)
First, update your system:
sudo apt-get update && sudo apt-get upgrade
Then we are going to install some packages that work really well with this issues. But first we need to remove laptop-mode-tools (if you didn't install it just go to the next step):
sudo apt-get remove laptop-mode-tools
Now, we have to install TLP:
sudo add-apt-repository ppa:linrunner/tlp && sudo apt-get update && sudo apt-get install tlp tlp-rdw
And also install thermald:
sudo apt-get install thermald
Finally, reboot your system and you are done!
Note: I don't know what driver you've installed. If this doesn't work, the easy way to solve it would be reinstalling elementary OS and then installing again TLP and thermald.
One other thing to note here is that if you are using Nvidia Graphics card with Optimus Technology and you are running official drivers. If you go to Nvidia X Server Settings, under PRIME profiles, you can select the Power Saving Mode which disables your Nvidia card and uses the motherboard's graphic card instead. This is essentially what Bumblebee does (kind of). This should also prolong your battery life. One thing to be mindful of here is that this could disable the graphics port connected to the card. For my laptop, this was the HDMI port; thankfully, the mini-display port is connected to the Intel Graphics card.
