@Lingalloway, Welcome to HP Support Community. 

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

Since your HP laptop won’t turn on even after installing a new battery and confirming it charged, here are some steps you can try to troubleshoot the issue:

Basic Hardware Checks

1. Remove all external devices: Disconnect USB drives, external monitors, printers, etc.
2. Try a hard reset:
   • Disconnect the power adapter.
   • Remove the battery (if removable).
   • Press and hold the power button for 15–20 seconds.
   • Reconnect the battery and power adapter, then try turning it on.

Check Power Supply

• Power LED indicators: Do any lights turn on when you plug in the charger?
• Charger test: Try using a different compatible charger if available.
• Battery test: Even if the battery is new, try powering the laptop with the battery removed and only the charger connected.

Display Issues

• Try shining a flashlight at the screen after powering on. If you see a faint image, the backlight or display might be faulty.
• Connect the laptop to an external monitor to check if it’s a screen issue.

Motherboard or Internal Hardware

If none of the above works:

• There could be a motherboard, RAM, or power circuit issue.
• Listen for beep codes or fan noise when pressing the power button, these can indicate hardware problems.
