Lenovo T430 with power issue need help

[manuel.it.solution]

Please a customer brought this Lenovo T430 laptop with power issue.
When you press the power switch the yellow led indicates the power is on and fan spins for 10 seconds and goes off with no display or stable power.

Please can anybody help me with schematics or what to do first?
Thanks in advance

I think that you have multiple posts on the same topic.

For starters, do as per suggestion by @SMDFlea.

The schematic should be probably the one posted here:
