Hi, I got a second hand MSI GF65 Thin 10UE. It doesn't power on and I thought I would have a go at trying to fix it. When the power button is pressed, nothing happens. It's completely dead. I tried the MSI battery drain to see if they fixed it but it did not. I took it apart to see if there is any burn marks but I can't see anything. Does anyone have any suggestions as to what I could look for or try? Thanks.
