I bought a X1 Carbon 7th Gen last month on lenovo website (august 2019).
I have overheating problem since a week now. When this happens i have a white (more or less white...) line blinking at the bottom of the screen.I'm 100% sure it's an overheating problem (or something that react when temperature increases) since it stops after some seconds everytime i'm putting a fan on the computer. I tried in "better battery" and "better performance" modes. Same result. It happens even with not intensive task like browsing the web....What is strange is that the laptop by itself isn't so hot, i put my ear on the fan but can't hear anything even if i have this white line caused by higher temperature. It looks like sometimes the fan is on but it looks like it happens more randomly.... i checked the processors cores temps with a software, the white line appears even when the processor cores temps are around 40/42 celcius degrees.
Thank you for your help.
