Consider buying a broken laptop.
it only starts the fans, LEDs, but otherwise remains black and does nothing.
what can that be?
Remote diagnosis via telepathy impossible.
If you have no idea about it, you shouldn't buy it.
The mainboard could possibly be defective. But you can't say that exactly.
Can be a lot. It is so (have to visualize it now) let's assume you have a thread and 8 glasses hang on this thread. The thread breaks and all glasses fall off… Well, they can all be broken or just a few, others have "only" cracks (which is also not a good thing) and others are intact. Ergo, you can't generalize this, especially not by remote diagnosis.
Mostly, however, it is the battery or the built-in rams. But as already mentioned, this can't be determined by remote diagnosis.
You also have to calculate something, because if the repair exceeds the current value of the laptop, it is not profitable anyway.
Lay answer: do not buy the device.
If you already have so little electronics knowledge that you have to ask about defective devices: Keep your hands off.
And when should I learn how to do it?
By rephrase your question.
You didn't ask about "purchase" after "purchase".
Well, know-how is acquired when you unscrew these boxes with basic electronics knowledge and see what is defective.
In terms of probability: the motherboard.
