Welcome to the HP Forums!
I understand the power input light on your notebook has been acting funky lately.
I took a look at your products user guide and found the following information on the power adapter light:
- White: The AC adapter is connected and the battery is charged.
- Blinking white: The battery has reached a low battery level.
- Amber: The AC adapter is connected and the battery is charging.
- Off: The computer is using DC power.
If the notebook is running on battery power and is not charging the adapter light will blink white. If the adapter blinks white while the adapter is connected this could be a sign that the adapter is not charging the battery. Have you noticed if the battery icon in your taskbar shows the battery is charging or not?
You may need to perform a hard reset:
- Turn off the notebook.
- Disconnect the AC adapter.
- Remove the battery.
- Press and hold the power button for 30 seconds.
- Reconnect the battery.
- Reconnect the AC adapter.
- Power on the notebook.
You may also want to test and calibrate your battery. You can see information on doing this here: Testing and Calibrating the Battery (Windows 😎.
Let me know how it goes.
Cheers.
