Hi Navind,
Thank you for reaching Microsoft Community.
I'm sorry to hear about what happened to your Surface Laptop. For the step 2 that you mentioned, this is basically doing a Force Shutdown on the device but please try to do it for 20 seconds (Press and hold the Power button for 20 seconds). Make sure to disconnect all extra peripherals first including SD cards, USB drives but leave the charger connected and confirm that the LED/tip is lit.
If still there is no response from the device, please contact support through our Global Customer Service phone numbers for further assistance and to check for replacement options available.
Hope this helps.
