[Kernel-packages] [Bug 77370] Re: Laptop Fan always on after resume from suspend to RAM
I am having this problem on a thinkpad t470s, ubuntu 16:04 LTS. It does not occur all the time, but in about 30 % of the cases after coming back from suspend. -- 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/77370 Title: Laptop Fan always on after resume from suspend to RAM Status in acpi package in Ubuntu: Invalid Status in linux package in Ubuntu: Won't Fix Status in linux-source-2.6.17 package in Ubuntu: Won't Fix Bug description: Binary package hint: initramfs-tools After doing a suspend to RAM, the fan is always "on" on my laptop, even if temperatures are low (where the fan would normally be off before going to sleep mode for the first time).

[Kernel-packages] [Bug 77370] Re: Laptop Fan always on after resume from suspend to RAM
I'm having this problem on my desktop running Ubuntu 16.04. After resuming from suspend, my CPU (or GPU, not sure) fan is spinning up a lot more than before doing a suspend. For example, I can watch Youtube videos without hearing any fan noise normally, but once I've resumed from standby the fan(s) spin up like crazy. -- 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/77370 Title: Laptop Fan always on after resume from suspend to RAM Status in acpi package in Ubuntu: Invalid Status in linux package in Ubuntu: Won't Fix Status in linux-source-2.6.17 package in Ubuntu: Won't Fix Bug description: Binary package hint: initramfs-tools After doing a suspend to RAM, the fan is always "on" on my laptop, even if temperatures are low (where the fan would normally be off before going to sleep mode for the first time).

1. before suspend, examine and remember all values of /sys/devices/virtual/thermal/cooling_device*/cur_state 2. after suspend, restore all values mentioned above. OR, for simplicity, just set the values of /sys/devices/virtual/thermal/cooling_device*/cur_state periodically. -- 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/77370 Title: Laptop Fan always on after resume from suspend to RAM Status in “acpi” package in Ubuntu: Invalid Status in “linux” package in Ubuntu: Won't Fix Status in “linux-source-2.6.17” package in Ubuntu: Won't Fix Bug description: Binary package hint: initramfs-tools After doing a suspend to RAM, the fan is always "on" on my laptop, even if temperatures are low (where the fan would normally be off before going to sleep mode for the first time).
