Hi @dmakhmammadov
Try a power refresh and check if that resolves the problem, in case it is a corrupted BIOS that is the cause of the problem.
* Disconnect the charger if connected.
* Open the laptop and disconnect the battery from the motherboard. (you don't have to remove the battery, just disconnect it). Here's a [https://www.youtube.com/watch?v=6Uw6lfZEtY4|video] that may help. Not your exact model but hopefully it is close enough to help.
* Press and hold the laptop's Power On button for a ''full 30 seconds'' and then release it. This should reset the BIOS back to its factory default settings.
* Reconnect the battery and reassemble the laptop.
* Connect the charger and try turning it on.
