HP DV6 6500 won't turn on at all. How to check if the battery / board / #3 option is faulty?

Question

HP

They threw me an HP DV6 6500 here , when I press the power button it does not react at all. They said it worked, but one day it just stopped working. I want to check what was wrong? There is no charging, they lost ahem, what kind of people ... Ordering a battery or charging for it is not a problem, but you need to make sure that all the same the problem is there. Or maybe there is something on the board itself ...
Is there a way to check this somehow?

Answer 1

Is there a way to check this somehow?

Of course there is, only in order to try to turn on the laptop - you need energy. And you have no batteries, no charger.
In such a situation, I advise you to look in Google and Yandex for typical malfunctions that this model may have.

Answer 2

problems found. I ordered a universal charger.
connected without battery. worked intermittently (turned off).
it turned out the charging socket was stupidly loosened
