Lenovo T450 - Intermittent shutting down problem

Hi all, didn't have much time this week, so I threw together a video of the starting of troubleshooting one of my own laptops which started shutting down intermittently.

Great video, keep the split screen its a great idea, love your preveous videos.

The split screen is nice. It gives the possibility to see where you are on the schematic and learn to understand it.

Split screen is a good idea.❤

You might want to check the 5V /3V regulator. Had a similar issue i fixed by replacing the 5V/3V IC . I used a thermal camera and found the chip flashing during the intermittent shutdown. Also check around the IC for partial shorts.

Love the split screen idea. So sad that I have to wait a week for Part 2!

Good split screen

i have the same problem with my T440 but it says "fan error" on the screen and shut down, fan spins regularly at start and stop as in normal working condition. But, when i opened laptop to get SSD out and copy some data, i returned everything on place and close back panel - laptop working normal. This make me to think that could be something with fan speed sensing line...
