I tried using the onboard Dell diagnostics and it shows that the current Processor Fan speed is about 2906 RPMs. It _did_ click loudly once and then appeared to pick back up. Attempts to run the test aren't yielding any high spin up/down noises like I'm used to hearing from other systems. Current thermal readings (inside of the diagnostics screen): CPU Thermistor: 65C Ambient Thermistor: 27 C SODIMM Thermistor: 39 C Video Thermistor: 54 C Back on the topic of the diagnostics, I'm running a CPU stress test and the CPU Thermistor has grown to 69 C. After some time the fan speed has finally increased to 3257 RPM and I can finally clearly hear that it is spinning. Once the test completed and the CPU temp started dropping, so did the fan speed, finally settling back to about 2900 RPM. I'm still puzzled why the laptop appears to lockup when attempting to login to the desktop environment when using CentOS, but not Ubuntu 15.04. Any thoughts there? Back on the topic of CentOS, I ran 'watch /usr/bin/sensors' for about 20 minutes and the temp only slightly fluctuated. It was only the login attempt that shut down the system.

Any thoughts there?I can't remember the whole thread but it seems you have an nvidia GPU and are using nouveau? If so, try installing nvidia-detect and then the correct nvidia driver for your system (from elrepo), and see if that helps. Could be a nouveau problem. http://elrepo.org/tiki/nvidia-detect

Could be a nouveau problem. http://elrepo.org/tiki/nvidia-detect Hello, I have received 4 of these machines today, with Nvidia graphics. I installed all 4 ( first minimal install, then Mate ) and that went ok. So far they didn't shut down. greetings, Johan _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
