CMOS chips were very susceptible to static, since even small amount of momentary current (in order of 30mA) could create a "Latch-up" where totem pole output (NMOS+PMOS) would become SCR-like structure. Latch-up would draw current and temperature would eventually kill the chip (matter of minute). Todays MOS ICs are designed with greater immunity to latch-up, but my first instinct when something is not responding after static zap, would be to turn the power off (to "un-latch").
I have whole house surge protector and good non-sacrificial protection in my Furman Elite 20PFi, but I still unplug during storms or when going on vacation. There is no protection that can stop direct lightning hit - up to 100 megavolts and up to 30 kiloamperes (according to Wikipedia).
