I’ve had a Dell Latitude E7450 for a few months now. Recently it froze while browsing and when I turned it back on, no beep/video/post. The flashing indicators were blinking solid solid like this image.

Got in touch with Dell, they did a motherboard swap the next day at my home. (3 year next-day business warranty FTW). They also changed the power jack and replaced the heatsink. A few weeks later, it’s been working fine. Yesterday it decided to crap itself on me again. Blinking solid solid.

Really frustrating. I haven’t reached out to Dell yet because I was wondering if there’s a way they would let me swap for a different model.
