Answer:
The first question you should ask yourself before performing the repair is Option B. Can you find a replacement motherboard.
Explanation:
According to me, I would ask “Can you find a replacement motherboard”.
Because, Always the laptop charge will be more than the charge of a mother board, because motherboard is just a part and the laptop consists of other important parts too. So Option (a) is not the wise selection.
Let’s look into option D. Warranty period should be verified by us and not the technical person, because we have purchased and we have the warranty card.
Let’s look into option C. The technical person will already be well-versed with fixing solution and diagnosing problem. So service manual will be of not much use to him and he would want to make money out of fixing the problem, so we cannot expect him to teach us how to replace a motherboard.
