Hi mostie,
I understand it can be frustrating. Apologies from my side for all the inconvenience caused. I would suggest you to drain out the residual power and then try to power on the system. if that doesn’t work, please provide me the Service Tag and the name as it appears on the account via private message (click my username and then click Start Conversation) so I may access your records and we will take it further from there.
Keep me posted with the information. I will be glad to assist you.
