When you press the power button, the laptop will turn on and display a picture with the word Dell, then immediately shut down. First, I refreshed the BIOS from a different place, then replaced the io chip, I measured everything on the gyroscope, everything is normal, I also checked the on button. Disconnected the entire peripheral device and replaced the RAM. Without RAM, the laptop could not be turned off. Everything seemed normal on the USB output. Tell me, can someone encounter such a problem?
