Now the issue is addressed and resolved.  Learning - Needs to escalate issue's then dell customer support consider the request with highest priority, otherwise they will take their own sweet time.  
Raised customer service request on 18th Jan 2022 regarding power issue and laptop is in dead state and Service team sent a person with mother board, but the laptop is in the dead state or zero battery and service engineer couldn't repair.  Requested one more time customer support for power adaptor, but till now no response from customer support and tried support team and asked them to escalate. But still my issue was not resolved. How to trust dell customer support ? Small issues are taking more than 10days.  Better thinking to move out from del l to other competitive products. SR:
