What happens if lightning strikes a PC/laptop?

Title, I didn’t know where else to ask and thought I might get the best answer here. My area has had a pretty big storm for the past 2 days with lightning knocking out our electric box, and during that time my laptop was plugged in. This afternoon when I got home from school I discovered my laptop wouldn’t turn on and it seems like the battery has finally kicked the bucket (it was already kinda weak at this point).

Like if lightening was the culprit, could it have potentially killed my motherboard as well, or is the damage only limited to my battery?
