So, I'm currently repairing a Samsung laptop for a customer and I'm having some issues diagnosing the problem. So, at first I believed the DC jack was broken because it is a little damaged. but then I decided to try using a universal charger and got the computer to start up. Although, the computer powers on, it allows me into the bios but doesn't let me do anything else. After it displays the Samsung splash the screen just continually blinks on and off. I don't think its just a windows boot issue because it doesn't allow me to boot into any other diagnostic programs.
So, I'm not sure if I'm just looking at the DC jack problem or a motherboard issue too. Has anybody seen this before? Any Suggestions.
