I bought Dell Vostro 15 3510 3510-5272 with alredy installed Ubuntu.
Unfortunately the fans don't work on Ubuntu. But in BIOS in during the start of the hardware test, the fan turns on and runs. But when the system starts, the fans turn off and do not turn on under load, and the laptop continues to heat up.
Driver `coretemp': * Chip `Intel digital thermal sensor' (confidence: 9)
To load everything that is needed, add this to /etc/modules: #----cut here---- # Chip drivers coretemp #----cut here---- If you have some drivers built into your kernel, the list above will contain too many modules. Skip the appropriate ones!
# pwmconfig version 3.6.0 This program will search your sensors for pulse width modulation (pwm) controls, and test each one to see if it controls a fan on your motherboard. Note that many motherboards do not have pwm circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls. The program will attempt to restore each fan to full speed after testing. However, it is ** very important ** that you physically verify that the fans have been to full speed after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
