I can't turn on the computer, it doesn't wake up

1. Check power supply (PSU)

  • Make sure the DC cable is not damaged and connected properly to the machine.
  • Make sure the AC cord is properly plugged to both sides (Wall mounted well plugged).
  • Trying an alternative adapter could eliminate bad PSU.

2. Check memory (RAM)

  • Verify RAM module is seated firmly in its socket.
  • Try to eliminate faulty memory sticks by swapping it with one another.

3. Check Peripherals (HDD/SSD/USB)

  • Unplug peripherals and try to power up with bare minimum, that includes HDD/SSD/USB devices.
  • Verify power up without storage. Sometimes damaged drives may cause the overall system to malfunction.
