I though I just share my experience with my new Dell Latitude E7450. I have received the laptop 2 days ago. I fell in love with it in no time for sure... Than, after 2 days, when I was browsing, the laptop suddenly was shutting down. It started to happen more and more often when I put it under moderate load. I was updating to the latest BIOS and drivers and the issue still did not go away. I thought it is over heating maybe so I turned off the auto shut down for over heating. Still I did not accomplish anything. Been on the line with costumer services for hours, to figure out what could be the issue as I was unable to run full test since the laptop was shutting down when it reached to the memory test. I thought it will be the memory? No, I could accomplish the memory test 2 times with no issues. Later on, it was shutting down in the middle of the tests or whenever I had an advertisement in the browser.
So far I`m waiting for a tech to replace the motherboard and the heat sink fan... I would not expect this to happen with close to the top of the price computer. I hope that the motherboard change will solve the issue but how was it tested if a moderate load on the CPU cause such an issue?
