The laptop does not turn on, what should I do?

Question

laptops

Good afternoon! Recently, my sister brought an irbis laptop and asked me to sort it out. as I understand it, she changed something in the BIOS, after which it turned off and does not turn on. When you try to turn on / connect the power supply, nothing happens, the indicators do not light up, but the usb connectors supply power. Thanks in advance to anyone who can help in any way!
