How to Fix Cash Register POS Reboot Loop Quickly and Easily
Common Causes of POS Reboot Loops
If your cash register POS keeps rebooting in a loop, it’s frustrating and disruptive. Understanding the common causes can help you fix the problem faster. Here’s what usually triggers a POS terminal stuck in a startup loop or continuous rebooting:
Power supply problems: Unstable voltage, a faulty power adapter, or issues with the electrical outlet often cause power interruptions, leading to constant restarts.
Overheating: Dust buildup, poor ventilation, or fan failure can cause your POS system to overheat, forcing it to reboot to prevent damage.
Software corruption: Failed updates, system glitches, or conflicting drivers can corrupt the software, causing a POS boot loop.
Hardware faults: Failing hard drives or SSDs, loose RAM modules, or motherboard problems can trigger system instability and endless restarts.
Peripheral conflicts: Printers, scanners, cash drawers, or other external devices sometimes cause boot interruptions by conflicting with the POS system.
BIOS/CMOS settings errors or outdated firmware: Incorrect BIOS settings or outdated firmware can prevent the system from booting properly, leading to reboot loops.
Knowing these common causes puts you one step closer to resolving your cash register boot failure and getting back to smooth retail operations.
Quick Safety Precautions Before Troubleshooting
Before diving into fixes for your cash register POS reboot loop, start with these safety steps to protect your data and hardware:
- Back up your data if possible. Use any available backup mode or external storage to save important sales records and settings before troubleshooting.
- Work in a static-free environment. Always unplug the power cord before opening or touching internal components to avoid electrical damage.
- Note any error messages, beep codes, or LED lights. These clues can help pinpoint the reason your POS system is stuck restarting.
- If your device is under warranty, contact SDLPOS support early. This prevents voiding coverage and ensures expert help for your POS reboot loop issue.

Step-by-Step Troubleshooting Fixes for POS Reboot Loop
When your cash register POS is stuck in a reboot loop, try these straightforward fixes to get it back up and running:
| Step | What to Do |
|---|---|
| Perform a Hard Power Cycle | Fully shut down the POS by unplugging it, wait 30 seconds, then power it back on. This can clear minor glitches causing the reboot loop. |
| Check Power Connections and Supply | Ensure all power cables, adapters, and outlets are secure and supplying stable voltage. Unstable power often causes POS system rebooting continuously. |
| Clean and Check for Overheating | Dust buildup can block vents and cause hardware overheating. Clean vents and fans carefully to improve airflow and prevent shutdowns or boot failures caused by heat. |
| Disconnect Peripherals | Remove printers, scanners, cash drawers, or other add-ons temporarily. Peripheral conflicts are common causes of POS boot loop troubleshooting challenges. |
| Access Safe Mode or Recovery Options | Boot into Safe Mode to load only essential drivers. From there, you can troubleshoot software issues without interference. Using Point of sale recovery options helps fix corrupted system files. |
| Run Startup Repair or System Restore | Use built-in repair tools to fix startup problems or roll back to a previous system state where the POS terminal functioned properly. |
| Advanced Hardware Checks | If problems persist, inspect for failing hard drives, loose RAM, or motherboard issues. Hardware faults often require detailed diagnosis. |
These steps cover common fixes for a cash register stuck restarting or caught in a POS reboot loop. For all-in-one POS units, regular cleaning and power checks can prevent many issues upfront.
