POS Has No Power
If the POS has no lights, no fan noise, and no sign of startup, start with the mains supply, adapter, and power cable path before assuming the terminal itself has failed.
Common causes
- Loose power cable or disconnected power brick.
- Wall socket or extension lead switched off.
- Failed power supply.
- Faulty POS power cable or internal hardware issue.
How to troubleshoot
- Check the power cable is secure and reconnect it fully at both ends.
- Make sure the wall socket or extension strip is switched on.
- Look for a power indicator on the power supply brick and test another socket if there is no light.
- Try a different socket or cable if a known-good replacement is available.
- If there are still no lights, sounds, or signs of startup, contact support.
If the power brick has no indicator light at all, that often points to the power supply or mains source rather than the POS screen itself.
What to check next
- Check whether other devices on the same power strip are working.
- Check for any visible damage to the PSU or connector tip.
- If the terminal powers intermittently, the issue may be with the cable, brick, or local socket stability.
FAQ
Should I restart the POS if it shows no power?
If there are no lights or signs of power, focus on the physical power path first rather than repeated restart attempts.
What if the socket works for other devices?
That makes the POS cable or power supply a more likely cause, especially if there is still no sign of life from the terminal.
When should I contact support?
Contact support if the terminal still has no power after checking the socket, power supply, and cable path.
