POS Terminal Turn On Troubleshooting

Modified on Wed, 23 Jul at 5:03 PM

Here are some troubleshooting steps for various scenarios when your Volcora Windows-based POS terminal doesn't power on or display anything. These cover multiple common issues including power supply, screen/display, and hardware faults:


 1. Power Adapter Issues

Symptoms: No lights, no fan sound, screen is black.

Steps:

  • Ensure the power adapter is securely connected to both the terminal and the outlet.

  • Test the power outlet with another device to verify it's working.

  • Check for any visible damage on the adapter or cable (fraying, bent pins, etc).

  • If available, test with a known working adapter with the same voltage/amperage.


 2. Power Button Lit but Screen Is Black

Symptoms: Power LED is on, but screen remains blank.

Steps:


3. Power Button Not Lit / No Signs of Power

Symptoms: Nothing happens when power button is pressed.

Steps:

  • Check Power Source: Try a different outlet or surge protector.

  • Power Button Hold: Press and hold the power button for 10–15 seconds in case the unit is in a "sleep" or low-power state.

  • Inspect for Loose Components: If comfortable opening the unit, check internal cable connections (motherboard, power board).

  • Replace Power Adapter: If adapter is suspected, try another compatible one.


4. Unit Turns On Then Shuts Down or Restarts

Symptoms: Boot loop, or shuts down after logo appears.

Steps:

  • Check for external devices (USB drives, barcode scanners, etc). Disconnect all and try booting again.

  • Attempt safe mode boot (F8 or Shift+F8 during boot—though not always accessible on newer systems).

  • Check for overheating (dust buildup, fan not spinning).

  • If boot logo appears, try entering BIOS (usually Del, F2, or Esc) to check if SSD is detected.


Other Tips

  • CMOS Reset (advanced): Remove the CMOS battery for 30 seconds and reinsert to reset BIOS settings.

  • Hard Drive Status: If the SSD has failed, the unit might power on but not boot.

  • Beep Codes: Some POS terminals emit beeps during POST (power-on self-test). Note the pattern and inform in your support inquiry.
