Hi, Thanks for reading this. I installed CentOS 7 (tried the latest ISO image and the previous build) on the laptop and got to the point where I am logging into the desktop environment and the laptop just shuts down. I check the event log in BIOS and find that a thermal event has occurred and the system powered off to prevent damage. I can take the same laptop with Windows 7 installed and run graphically intensive tests for an hour solid and it doesn't lock up. I installed Ubuntu 15.04 and that seemed solid too. Is this a known issue with CentOS 7? Should I be using a particular boot option? It does not seem to matter whether Gnome or KDE is chosen as the desktop environment. Any help you can provide is appreciated. Thanks.
