It can be incredibly frustrating when your Autel OBD2 scanner, a crucial tool for vehicle diagnostics, suddenly refuses to power on. You’re ready to troubleshoot a car issue, and your scanner becomes unresponsive – leaving you stuck. Don’t worry, you’re not alone. Many users encounter this problem, and fortunately, in most cases, it’s resolvable. This guide will walk you through common reasons why your Autel OBD2 scanner might not be turning on and provide step-by-step troubleshooting methods to get you back on track. We’ll cover everything from simple fixes to reporting the issue if necessary, ensuring you can diagnose vehicle problems efficiently again.
Common Scenarios: When Your Autel Scanner Won’t Power Up
Users often report their Autel scanners failing to turn on in a few typical situations:
- Brand New Scanner Out of the Box: You’ve just received your new Autel OBD2 scanner, eagerly unpackaged it, and pressed the power button – only to be met with a blank screen. This can be concerning right away.
- Sudden Power Failure During Active Subscription: You’ve been using your scanner without issues, and it’s still within its subscription period for updates and support. Suddenly, it won’t power on, disrupting your workflow.
- Scanner Unused for a While, Subscription Expired: Your Autel scanner has been sitting idle for some time, and its software subscription has lapsed. Now, when you need it, it refuses to turn on.
Understanding these scenarios helps pinpoint potential causes and apply the appropriate solutions.
Decoding the Silence: Why Your Autel OBD2 Scanner Won’t Turn On
Several factors can prevent your Autel scanner from powering on. These generally fall into three main categories: battery problems, software glitches, and system-level issues.
1. Battery Issues: The Lifeline of Your Scanner
The most common culprit is often battery-related. Here’s a breakdown of potential battery problems:
- Complete Battery Drain: If the scanner has been left unused for an extended period or was not properly charged, the battery may be completely drained and unable to power the device.
- Charging Malfunction: Even when plugged in, the scanner might not be charging correctly. This could be due to a faulty charger, a damaged charging cable, or an issue with the scanner’s charging port itself.
- Battery Degradation (in older scanners): Like all rechargeable batteries, those in OBD2 scanners degrade over time. Older scanners may have batteries that no longer hold a charge effectively, leading to power issues.
Troubleshooting Battery Problems:
- Connect to Power and Observe: The first step is to connect your Autel scanner to its charger using the provided cable and a known working power outlet.
- Check for Charging Indicator: Look for a charging light indicator on your scanner. This is usually a small LED that illuminates when charging. If the light doesn’t come on, try a different power outlet and ensure the charger is properly connected to both the scanner and the power source.
- Charge for at Least One Hour: Even if the charging light comes on, allow the scanner to charge for at least one hour before attempting to power it on. A deeply discharged battery may need some time to regain enough charge to start up.

- Test with a Different Charger and Cable (if possible): If the charging light still doesn’t appear, try using a different compatible USB charger and cable to rule out a faulty charger or cable.
If, after these steps, your scanner still shows no signs of charging or powering on, the issue might not be solely battery-related.
2. Software Crashes: When Digital Brains Freeze
Like computers and smartphones, OBD2 scanners rely on software to function. Software crashes or glitches can sometimes prevent the scanner from booting up.
- Software Freeze or Error: A temporary software malfunction can cause the scanner to become unresponsive, including failing to power on. This can happen due to various reasons, including interrupted updates, corrupted data, or internal software conflicts.
Troubleshooting Software Crashes:
- Force Restart (Reboot): The first and often most effective step is to attempt a force restart. The method for force restarting an Autel scanner can vary slightly depending on the model, but it generally involves holding down the power button for an extended period (usually 10-20 seconds). Consult your scanner’s user manual for the specific force restart procedure for your model.
- Observe for Any Response: After a force restart, try pressing the power button again to see if the scanner powers on. Sometimes, a simple reboot is enough to clear a temporary software freeze.
If a force restart doesn’t solve the problem, the issue might be more persistent.
3. System-Level Problems: Deeper Issues
System-level problems are less common but can also prevent your Autel scanner from turning on. These can involve issues with the operating system or firmware of the device.
- System Incompatibility or Errors: If the scanner’s system software is outdated, corrupted, or incompatible, it might fail to start up correctly. This can sometimes occur after software updates or if the system files become damaged.
- Long-Term Neglect of Updates: While less likely to directly cause a complete power failure, neglecting software updates for a very long time could potentially contribute to system instability over time in some devices.
Troubleshooting System Problems (with Caution):
- Clear Cache (if possible, model-dependent): Some Autel scanners have options to clear the system cache from a recovery menu (if you can access it). This can sometimes resolve system-level glitches. Consult your user manual for instructions if your model supports cache clearing and how to access the recovery menu (if possible without powering on).
- Factory Reset (Use with Extreme Caution): A factory reset will restore the scanner to its original factory settings, potentially resolving deeper software issues. However, performing a factory reset on an Autel scanner outside of its software update subscription period can have serious consequences. As the original article mentions, it can delete all pre-loaded software, and you may need to repurchase the update service to restore functionality. Therefore, attempt a factory reset only as a last resort and if you are certain you understand the potential risks and consequences for your specific scanner model and subscription status. Consult your user manual for factory reset instructions if you choose to proceed.
Important Note on Factory Resets and Software Subscriptions: Autel scanners often require active software subscriptions to receive updates and maintain full functionality. Performing a factory reset on a scanner with an expired subscription can lead to data loss and require paid reactivation of services. Proceed with extreme caution and only if advised by Autel support or if you are fully aware of the risks for your device.
Reporting a Power-On Failure: When to Seek Professional Help
If you’ve exhausted the troubleshooting steps above and your Autel OBD2 scanner still refuses to power on, it’s time to report the issue to the vendor or Autel support for further assistance.
Steps to Report a Power-On Failure Effectively:
- Document the Problem with Video: Create a short video recording demonstrating that your Autel scanner is not turning on. This visual evidence is very helpful for support teams to understand the issue quickly.
- Locate Your Scanner’s Serial Number (SN): Find the serial number (SN) of your Autel OBD2 scanner. This is usually located on a sticker on the back or bottom of the device, or possibly in the device’s packaging or documentation. The SN is crucial for identifying your specific model and its software update status.

-
Contact Your Vendor or Autel Support: Reach out to the website or vendor from whom you purchased the scanner or directly contact Autel customer support. Provide them with:
- Your video evidence of the power-on failure.
- The Serial Number (SN) of your scanner.
- Details of when and where you purchased the scanner (if possible).
- A summary of the troubleshooting steps you have already tried.
-
Request a Flash Package or Repair Options: Based on your SN and the scanner model, the support team can verify your scanner’s upgrade period and provide you with appropriate solutions. This might include:
- Providing a “flash package”: This is a software package that can potentially be used to re-flash the scanner’s firmware and resolve system-level issues (usually requiring specific instructions from support).
- Guidance on repair or replacement: If the issue is hardware-related or cannot be resolved remotely, they will guide you through the process of sending the scanner in for repair or potential replacement under warranty (if applicable).
Important Reminder: Be cautious about attempting to format or re-flash the scanner yourself without explicit instructions from Autel support, especially if your scanner is outside its update subscription period. Incorrectly formatting the device can lead to software loss and require paid service reactivation.
By following these troubleshooting steps and knowing when to seek professional help, you can effectively address the issue of your Autel OBD2 scanner not powering on and get back to diagnosing vehicle problems with confidence.
