HP Latpto new one - Only orange light blinks , no other sound, beeps etc , did all trouble shooting

[abhireet]

I have a two years old HP Laptop : AMD Ryzen 15 3450u . It has suddenly stopped working, to the best of our understanding nothing we did except seeing the mails, youtube videos etc.  Almost ten days now,  when  the original adapter ( came along with the system when we bought first time), it starts blinking orange light ( amber like), when I remove adapter it stops. No other sounds, fan or beeps etc we hear. As advised online by HP team, I did trouble shooting like holding for 20 seconds, then Windows B, Windows V,  Esc while inserting AC adapter in to the system. Always only orange light, but when battery is removed it shows white light, again orange after battery is inserted.  What might have gone wrong with the system. Are there any other self trouble -shootable steps or visiting service Centre is the only option available. Once we visit service canters commercial greed dominate  & we will be forced to pay for parts unnecessarily. Once they touch internal parts there may be recurrence of repairs as every one knows we rarely get a good professional genuine service providers these days.  Correct answer from our respected community professionals will help me to maintain the Laptop for some more years.
