Question Lenovo T450 blank screen

[tempid]

Laptop dropped to floor < 2 ft. When powered on I can see blank/black screen. Connected to different monitor but see the same problem. Opened the laptop. When I power it on, CPU fan runs for a few seconds and stops. What else I can check? Thank you!

T models can take a decent amount of beatings, but seems yours hit just right to damage something. Did you re-seat the RAM and any cable connections?
