If the laptop is behaving, then you got lucky. Damage is usually pretty obvious. Suggestion I have is to at least make sure all important electronics is connected through a surge suppressor minimum with coax suppression as well to protect broadband modem and network equipment as well as TV etc.
For my home I have multiple battery backups with surge suppression. 4 of them rated for 750VA each. *Which reminds me, they dont last for ever the batteries age and some of mine are almost 8 years old. I should probably test them or replace batteries or get new battery backup units to replace the older ones.
