@KR101 Note that specific patterns of long and short blinks along with long and short beeps (where applicable) identify errors during the startup process.
Newer computers have two-part blink sequences with different color lights to indicate specific errors and you may click here and troubleshoot on your own,

Also, do tell which indicator light are you referring to? if you wish to seek precise guidance from the HP community.

Meanwhile, Let's perform a power reset as per HP standards:

• Ensure your laptop is OFF.
• Unplug all the external devices (If any).
• Disconnect the power charger from the computer, and remove the battery.
• Press and hold the power button for about 30 seconds.
• Connect the power supply (power adapter).
• Press the power button to turn on your laptop.
• Then put your battery back.
