I recently bought a new Lenovo IdeaPad 520-15IKB 81BF005JRK laptop and installed Ubuntu (18.10 downloaded a few days ago, during install, updates were installed). But I cannot work with it as immediately after turning on the laptop, the processor (i8520u) on all cores operates at maximum frequencies (over 3 GHz) and goes into hard trotting with pauses of 20-30 seconds. I have some time open the console, but I can not execute any command. It's owful. I cann't install cpufrequtils, cpupower or other software
I tried to boot from a live-usb (there are no such problems) and edit /boot/config-* : #CONFIG_CPU_FREQ_GOV_PERFORMANCE CONFIG_CPU_FREQ_GOV_POWERSAVE=y the governor was established to POWERSAVE but the laptop still works at the maximum frequency. may be I can Add `intel_pstate=disable` to `GRUB_CMDLINE_LINUX_DEFAULT` in /etc/default/grub but I don't know how update-grub at GPT UEFI partition. It even sometimes seems to me that with each new start in such a boost it slows down more and more, I'm afraid, as it were, that it does not kill the processor on a new computer. After the first installation, I didn’t immediately notice trotting and left the computer for the night. And now it's just not possible to work with him -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1598394 Title: intel_pstate has too aggressive frequency selection Status in linux package in Ubuntu: Confirmed Bug description: I was recently upgrading from Ubuntu Gnome 15.10 to 16.04 on my ThinkPad. Before the frequency-scaling chose the minimum possible frequency when the system was on low load. Now, when I allow the CPU to choose anything between the lowest and highest possible frequency, it sticks to the highest frequency for 90% of time and only occasionally drops to the low frequency. I can confirm (htop) that my system load is practically zero. Also the CPU Power Manager Applet from Gnome Shell works well, because I can force low frequency by reducing the maximum allowed frequency and can also switch off Turbo Boost.
