Can Wrong AC Adapter fry motherboard?

[ftdsn244]

Hello, my nephew put an adapter in my cousins laptop and it does nothing now, could that have friend the motherboard? As far as I know the charger he put in is not even a laptop charger as they only have 1 laptop at the house. I was not there and have no seen the charger he tried to use but I know it cannot be a laptop one.

I tried taking out the battery and using adapter with nothing happening. Tried taking out ram just to see if it turns on, nothing. No lights, no noises nothing at all. I am guessing he fried it? Any other way to check if a motherboard is fried? Thanks

Can Wrong AC Adapter fry motherboard?
Yes, it happens, when the power of the adapter is lower than the laptop requires, for example, your original adapter is 90w and a 65w adapter of lower voltage can not provide enough power, which might cause harm to both the adapter and laptop.
