Hi @Region3,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your HP Envy x360 2-in-1 15 isn't powering up despite following those troubleshooting steps, several potential causes could be at play. Here's a list of possible issues and things you can further investigate.

Motherboard or Power Circuit Failure

• Since the charging light and power button illuminate, the problem may lie deeper in the power delivery system. The motherboard could have a damaged power circuit, preventing the laptop from fully powering up.

Solution: You may need a technician to inspect the motherboard for damage, burnt components, or short circuits.

Battery or Charging Circuit Issue

• Even though you've removed the battery and used a new charger, it's possible that the internal charging circuit is damaged. This could prevent the laptop from properly drawing power from the charger.

Solution: Checking with an external power supply, if available, to test the charging circuit might help.

Power Button Failure

• If the power button is damaged internally or not making proper contact, it might register a press but not fully initiate the startup process.

Solution: You could try opening the laptop and checking if the power button is functioning correctly or if it needs replacement.

BIOS or Firmware Corruption

• A corrupted BIOS could cause the laptop to not power on or show any signs of life, even if other hardware is functioning.

Solution: Try performing a BIOS recovery:

• Turn off the laptop.
• Hold the Windows key + B key while pressing the power button for 2-3 seconds.
• Release the power button but continue to hold the Windows + B keys.
• If the BIOS recovery screen appears, follow the prompts to restore the BIOS.

Faulty RAM or RAM Slot

• Though you've swapped RAM slots, the issue might be with the RAM modules themselves, or there could be a problem with both slots.

Solution: Test the laptop with a different RAM module, if available, or try each RAM module individually to rule out the possibility of faulty RAM.

Loose or Disconnected Cables

• Internal cables that connect the motherboard to the power button, screen, or other components may be loose or disconnected.

Solution: You can open the laptop and check for any loose connectors, particularly between the power button, motherboard, and screen.

Overheating or Shorted Components

• A short in the system due to overheating or another failure could cause the laptop to shut down completely and not restart.

Solution: If possible, inspect the laptop for any obvious signs of damage like burn marks, and ensure the cooling system (fan, thermal paste) is in good condition.

Damaged Power Jack or DC-IN Connector

• The port where the power adapter connects to the laptop (DC-IN jack) might be damaged or loose, preventing proper power delivery to the internal components.

Solution: A technician can check the DC-IN jack to see if it's faulty or loose.

I hope this helps.

Take care and have a good day.
