I can not turn on the it does not boot

1. Possible reason: Power supply failure

Solution - Check power supply (PSU)

  • Check that the LED on the PSU is lit green. If not, check that it is connected to a functional AC outlet.
  • Check that the power button on the front panel is lit. If not, check that the DC plug is inserted correctly into the jack at the rear panel of Tensor-PC.
  • 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)

The most common reason is RAM that is not installed or incompatible. Tensor-PC supports DDR4 DIMM. Note that registered (buffered) DIMM is not supported.

  • Check that RAM is compatible and installed correctly.
  • If you have multiple DIMM modules you may leave only one and change its slot.
  • Try powering up again until RAM is detected properly.

3. Possible reason: Peripherals/TELs failure

Solution - Check Peripherals (HDD/SSD/USB/Modem/WiFi module) and TELs

  • If you can access BIOS - check whether all TELs are recognized properly
  • Check whether all TELs are correctly connected to the appropriate TRIPs. Check the TEL to TRIP correspondence table
  • 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.

4. Storage issue or missing operating system

  • Ensure a storage device is installed and detected in BIOS settings.
  • Check boot order in BIOS settings.
  • Ensure that an operating system is installed on the selected storage device.

5. Tensor-PC BIOS reset

Reset BIOS settings to default for Tensor-PC revisions 1.2 and later:

  1. Unplug power cable from the Tensor-PC
  2. Remove the 4x Phillips Chassis screws
  3. Remove bottom and top cover
  4. Remove the RAM stick
  5. Plug in power cable (should turn on automatically), and Wait ~10 seconds
  6. Unplug power cable
  7. Assemble back the RAM stick
  8. Press the RTC reset button.
  9. Plug power cable (should be automatically turned on)

BIOS settings should be reset to defaults.
