@guesty64326 a faulty battery should not be doing this, for as long as your computer comes on. You are not saying if you have any sign of life on this device. For now, download the maintenance manual for your computer from here and start with the power system checkout.
If you have power and if your computer comes on, connect an external monitor to your computer. Let us know what that displays.

Is there any kind of a fuse between the power supply unit and the laptop. I do not see to have any power at all
What is the model number of the laptop?
Have you checked that there's the correct DC voltage available at the output plug of the charger that is used with the laptop?
I have a Lenovo B590 that has a problem and some repairers say it is from the cooling unit. When I turn it on, it makes a “tink-tink” sound and then turns off again. Now, after a period of not using it, when I press the power button, it does not turn on at all and does not give any response.

Realy this problem is coolin unit?
Does the laptop indicate that the battery is being charged when an appropriate charger is connected to the laptop?
If it does allow the battery to fully charge and then try turning on the laptop with the charger still connected and check what happens
