Would this be possible to implement in HwInfo? How far implemented is the EC/SMM driver for Dell Laptops in HwInfo? I found these two implementations, one SMM Windows driver port, which is based on the Linux i8k driver or something I think? But it fails to load for the 9570Īnd this one which basically also uses the same registers Found some information on the web, that there is a way to set a register at least for 9550/9560 deactivating the EC fan control Sending values to the fans works with HwInfo, but the EC overwrites them immediately again. See doc/fan-divisors for more information.I wonder if it would be possible to implement a write to / dump EC register mechanism into HwInfo? I am actually trying to find a way to deactivate EC fan control and let HwInfo control the fans, for the Dell XPS 15 9570.

You may also need to increase the fan divisors. Make sure you have a 3-wire fan connected. There are no working fan sensors, all readings are 0. Giving the fans some time to reach full speed. Physically verify that the fans have been to full speed However, it is ** very important ** that you The program will attempt to restore each fan to full speedĪfter testing. We will attempt to briefly stop each fan using the pwm controls. Note that many motherboards do not have pwmĬircuitry installed, even if your sensor chip supports pwm. This program will search your sensors for pulse width modulation (pwm)Ĭontrols, and test each one to see if it controls a fan on This is the output of pwmwconfig from fancotrol: # pwmconfig version 3.6.0 I checked the hardware and the fans seems okay.Īlso before I uninstalled windows 7, the fans were working okay, so I know it is not a hardware problem. The CPU fans are not working at all on my DELL Inspiron 15R N5110, I am running Ubuntu 20.04.2 Server, and the laptop overheats quickly after a small duration of uptime.
