Can you boot the laptop into BIOS ?
Can you boot a UM20.04 live usb stick?
If yes, does wifi work?
if yes, install gparted in case it is not there (sudo apt install gparted)
Check if gparted "sees" the ssd (top right should show all devices not just the usb stick)
I doubt it the laptop is a brick, use logic steps to troubleshoot.
