today I upgraded the RAM and the SSD of my T480. I am absolutely not doing this for the first time and I was really careful. I removed the external battery and deactivated the internal battery before starting with the procedure. I used only ESD-safe tools and an ESD-wristband to make sure that the device doens't get damaged by static discharge.
After installing the components, my device would no longer turn on. When I connect the charger, the power led flashes 3x but when I press the powervbutton nothing happens. No fan spin, no lights turning on, absolutly nothing.
I then tried removing the RAM and the SSD and turning on the machine. But that didn't work as well.
After that I tried removing all the power sources (internal and external battery, CMOS-battery), pressing the power button for 60 seconds and leaving the device for 1 hour before reconnecting everything. But it still can't turn it on.
Do you guys have any idea what I could try to make my device work again?
Thanks in advance.

I would reach out to Lenovo to solve this issue. There are other forum posts about this, that all resolve in them having to send their system into Lenovo or having a repair tech from Lenovo come to them to check the system board.
Sorry no immediate solution..

Hey resonance were you ever able to resolve this issue? How did it turn out? Sounds like a loose cable somewhere to me... When upgrading my first thinkpad I unknowingly disconnected a cable and it took a lot of time and panic before I had realized what had happened.
