Hi Gerihc90,
Thank you for the response. This system has a separate DC-in jack. The first suggested part replacement would be the DC-in jack. If the issue persists, the you may consider replacing the motherboard.

if your system is under warranty, then you may provide the service tag of the computer and the first and last name as it appears on the account via private message (click my username and then click Start Conversation) so that I can check the further course of action.
If the warranty has expired, then let me know the country you are located. I will share the contact details.
