Hi, My HP Spectre 360 switches off completely when not on power supply.   I changed the battrey recently to try solving the problem but the issue persists.     The laptop goes off when not on power and then I have system board error.

Hi  @mgauci,
 
Welcome to the HP Support Community!

Thank you for reaching out.

 I understand that your HP Spectre x360 is shutting down whenever it is disconnected from the power adapter, and that the issue continues even after replacing the battery. I appreciate the troubleshooting you have already completed, and I will be glad to assist you further.

To help us better understand the issue, kindly confirm the below details:

• Does the battery charge normally to 100%?
• When the laptop shuts down, does it power off immediately or show any warning message first?
• Could you kindly let us know the exact System Board error message or error code you receive?
• Have you noticed any battery warning messages in HP PC Hardware Diagnostics or BIOS?
• Also kindly confirm the battery replaced was it from HP or third party ?

In the meantime, kindly try the below steps and confirm :

1. Perform a Hard Reset (Click here for steps )
   • Shut down the laptop.
   • Disconnect the AC adapter.
   • Press and hold the Power button for 15-20 seconds.

   • Turn off the notebook.
   • Power it on and repeatedly tap F2.
   • Run the Battery Test and System Board Test.
   • Kindly share the results or any failure IDs displayed.
