How to fix acer aspire one k270 laptop not turning on?

Question

Iron

There is an acer laptop that does not turn on, when you press the power button, it turns on the cooler, turns on the indicators, but the screen is black. I connected vga to my monitor (there is a port on the laptop), but there is no signal. I tried using livewoosb, but it didn't work.

I don’t know about your Acer, but usually computers that are completely devoid of all screens switch to communicating with the user through sound, i.e. by short and long beeps. So, your operand mode is the following - open the laptop and disconnect the cable that goes from the motherboard to the screen, then make an attempt to start.
If it beeps, it means that the video subsystem is alive, and you can try to decipher these beeps (as usual, through Google). If it doesn’t beep, replace the motherboard, which makes little sense, since in terms of money it is almost equivalent to buying another laptop.
