I have a laptop lenovo g50-30
4 gb ram
cpu Quad-Core Intel® Pentium® CPU N3540 @ 2.16G
video: nVidia GeForce 820M
is running elementary os (there were other linux distributions before, but the problem is the same)
the laptop freezes after a while time (does not react to anything) with this cpu loaded by 20-40%
I thought the problem was in the RAM, I tested it through memtest86 - everything is ok. no mistakes.
What to do?

I got up dead on my laptop with Intel guts on 16.04, and searched for a problem for a long time until I found this: ... “If it hangs tightly on distra higher than 14.04.3, then 99% that this is due to Intel graphics. I had regular freezes after 20 - 40 - 90 min. It was decided so sudo gedit /etc/default/grub bring the line GRUB_MDLINE_LINUX_DEFAULT to the following form (if nothing was added) GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" Save, close. sudo update-grub And reboot. The problem should disappear if Intel HD is to blame. "... IT HELPED ME. I specifically drove for a week without reloading the video in the chrome browser.
