Possible Causes:

  1. Power Supply Issues:
    • Cause: The laptop might not be receiving power due to a faulty charger or a damaged power port.
    • Tips:
      • Ensure that the charger is properly connected to both the laptop and the power outlet.
      • Try a different charger or power outlet to rule out cable or outlet issues.
  2. Battery Problems:
    • Cause: A depleted or faulty battery can prevent the laptop from turning on.
    • Tips:
      • Plug in the laptop and allow it to charge for a while before attempting to turn it on.
      • If the battery is removable, try removing it, plugging in the laptop, and turning it on without the battery.
  3. Hardware Failures:
    • Cause: Internal hardware components, such as the RAM or hard drive, might be malfunctioning.
    • Tips:
      • Try reseating or replacing the RAM if you are comfortable doing so.
      • Listen for unusual sounds like clicking or grinding, which might indicate a failing hard drive.
  4. Software or OS Issues:
    • Cause: Corrupted system files or a failed OS update can lead to startup problems.
    • Tips:
      • Attempt to boot the laptop in safe mode to bypass any problematic software.
      • Use recovery options or installation media to repair or reinstall the operating system.


  1. Perform a Hard Reset:
    • Solution: Disconnect the charger, remove the battery (if possible), and hold the power button for about 30 seconds. Reconnect the battery and charger, then try turning the laptop on.
  2. Check for External Devices:
    • Solution: Disconnect all external devices (USB drives, external monitors, etc.) and try turning on the laptop again. Sometimes, a faulty external device can cause startup issues.
  3. Run Built-in Diagnostics:
    • Solution: Lenovo laptops often have built-in diagnostics tools. Consult the user manual or Lenovo’s website for instructions on running diagnostics to identify hardware issues.
  4. Seek Professional Assistance:
    • Solution: If none of the above steps work or if you are uncomfortable performing hardware-related troubleshooting, consider contacting Lenovo’s customer support or a certified technician for further diagnosis and repair.
In conclusion
When your Lenovo IdeaPad S145-15IWL fails to turn on and auto-diagnosis repair fails, it’s essential to remain calm and systematically troubleshoot the issue. By identifying potential causes, following the provided tips, and attempting the suggested solutions, you can increase the chances of successfully resolving the problem and having your laptop up and running again.
