Hi friends, By all means I have been unable to ensure that my CPU fan works well because it cannot be detected by /proc/cpuinfo, dmidecode, sensors, various ACPI fan scripts etc. My laptop sometimes hangs and then shuts down and then gets stuck at boot with black screen. But this happens sometimes. I am of the view that my CPU fan does not function properly and on detecting high temperature it shuts down. So far I have come to the conclusion that there is lack of support from ACPI on my Acer Aspire V5 571G. Another problem I face is my laptop gets stuck in shutdown-reboot loop be it Kali Linux, be it Ubuntu. Any idea to get around this folks? I am using Ubuntu 14.04.02 on Acer Aspire V5 571G.
