I can't turn on the Tensor-I20 computer, it doesn't wake up

1. Possible reason: Power supply failure

Solution - 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. Possible reason: Memory failure

Solution - 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. Possible reason: Peripherals failure

Solution - 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.

  1. Unplug power cable from the Tensor-I20
  2. Remove bottom cover
  3. Remove the RAM stick
  4. Plug in power cable (should turn on automatically), and wait ~10 seconds
  5. Unplug power cable
