Start with 2 years of electronics school so that you can identify components, how they work, and how to make measurements.
While it is a lot easier to troubleshoot when you have a schematic, once you have a good understanding of electronic components, you can start to probe the circuits to see what is wrong.
I usually start with the power supply circuits. If you don't have the correct voltages, nothing will work.
Where I go next depends on the problem. You need a good scope to verify the primary clock circuits.
After that, with a laptop you start to reach the point where the cost of replacing parts exceeds the value of the repair.

No two-year electronics course will give you the "bench" experience with computers.
The same would apply to many other electronics specialties.

That without proper electronics training and *lots* of troubleshooting experience, you not attempt to probe anything in a modern computer, you can do serious damage just by touching te circuit board with your finger, and slipping with a probe can do even worse.
Call a qualified electronics technician who specializes in component-level computer rpair..
