Hi @Stevesandy,

Welcome to the HP Support Community

I understand you are facing an issue with your HP15.6-inch Laptop. Not to worry I will help you to get a resolution to resolve the issue.

Please try the following Troubleshoots steps. 

1.    Turn off the Unit.

2.    Disconnect the AC adapter.

3.    Remove any discs from the disc drive.

4.    Remove memory cards from the card reader slot.

5.    Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.

6.    Disconnect the AC adapter press and hold the power button for approximately 15 seconds.

7.    Reconnect the AC adapter, and then turn on the computer.

Step 2

Turn off the unit and please press and hold the Windows key + letter B key and the power button together for 30 seconds after 30 seconds, 1st release the power button but keep holding the Windows key and B key for ten more seconds and then release these two keys If done correctly, you will see the display flashing once. Please attempt it thrice as this step and Restart the unit

Step3

The unit has to be turned off, Press Win+ V while holding these two keys then Press the Power button, continue to hold all three keys for 30 seconds and then release the Power button first and then release these two keys Please attempt it thrice  and then you may get a Pop-Up CMOS Check and it will restart the unit 

Even if you don't get a Pop-up restart the unit manually after 3 attempts.

If the power light is blinking then try to check the charger,  connecting another charger if the light is glowing study so that the battery is charging well  then its good and it's blinking then we have to check if there is any hardware issue

When the light next to the power light stops blinking, it may indicate a specific status change (e.g., completion of a process or an error), depending on the device or system you are referring to.

Thank you for your reply 

Understanding HP Smart Adapter messages

Using an AC power adapter not designed for your computer can cause the notebook to display a notification message in the bottom right corner of the screen.

Use the power adapter that came with your notebook for the best performance.

NOTE:

If the HP Smart Adapter message displays when you are using the power adapter provided with the notebook, then update to the latest BIOS version for your notebook.

Power output too low message. This message indicates the power adapter does not provide enough power for the notebook computer to be used. The battery light might blink rapidly eight (8) times and the battery icon in the system tray indicates the computer is operating on battery power.

Understanding the AC power adapter lights

Depending on the model, the battery indicator or AC power adapter light LED might be white, green, or amber when the power adapter is connected and is providing power to the notebook.

Most notebook computers have a power adapter light in the area near the power connector. If the light is on, then the power adapter is functioning properly.
