Elitebook 855 g8

Hi i have a hp EliteBook 855 g8.. today suddenly when i pressed the power button the laptop powers on but the caps lock and NumLock gives a short blink. And when i power it off ,the power button light goes off and the charger led blinks once. Does anyone have any idea what this means and how to solve this issue. Thank you.
To be noted that, i tried disconnecting the battery and holding the power button for 45 seconds. But the blinks are still happening when powering on and off laptop runs and works
