Tell him you suspect the electrics in his house before returning it. My guess is that the grandson did something daft, and may have actually nadgered the surge protector, so ask him to try it without the surge unit. (unless you are in an area with overhead electric supply cables and prone to lightning, they are pretty useless anyway)
If the repaired pc works ok then talk about replacing the SSD.
