Try these steps:

Check Power Supply:

• Check if the charging port and connector are free of debris and secure.

Battery Diagnostics:

• The error code you received during the battery test indicates a problem. Refer to the HP Battery Validation page to understand the specific issue associated with this code.

BIOS and Firmware Updates:

• If you can get the display to work (using an external monitor or otherwise), ensure the BIOS is updated to the latest version available on the HP Support website.
