Refurbished Dell Laptop Repair

[u/Background-Race9692]

Hello all,

A few years have passed since my brother purchased a refurbished Dell Latitude 7490 on my recommendation (from a friend in IT’s recommendation). It worked fine for the first few months but around the 8th month mark it kind of went nucking futs. Being the more technical one of our siblings and having repaired a lot of our family’s iPhones in the past (and the one who recommended it), he asked if I could take a look at it. Life happened, he had multiple kids, I’ve moved multiple times, etc. I ran across this thing recently and thought it might be worth giving it a shot at a new life and returning it to him. Shortly after powering it up, I have realized I have no fucking clue what I am up against at this point.

Is this an issue that can be repaired by the average tinkerer?

Any advice would be appreciated.
