HP Pavilion G6 Won't Boot After HDMI Cable Was Plugged In

I had the same thing happen to me. HP 2000 2d27dx is three prong on a surge, but Vizio smart TV is 2 prong and on the same surge protector. .... any solutions or does this mean it's fried?

When I trying to boot multiple lights blink continously (wifi, network, SD card...) and hard reset nor bios restore did anything to help.

Safety ground at an appliance or protector is completely irrelevant. Surge protection is always about another electrically different ground. Protection is always about where hundreds of thousands of joules harmlessly dissipate - in earth ground.

Two wires or three are simply two or three more wires that a surge might use to destroy the appliance. Any protection at an appliance is bogus for the other and destructive type of surge. Protection is always about connecting that current to earth BEFORE it enters a building. As was understood and repeatedly demonstrated over 100 years ago.

Safety ground, chassis ground, and earth ground may be interconnected. Still, all remains electrically different. Critical to protecting the structure is a connection from the cloud to earth via a lightning rod. Critical to protecting appliances is a connection to earth via a hardwire or surge protector - on a path that also remains outside a building.

Protectors adjacent to an appliance (with or without a wall receptacle safety ground) can even make appliance damage easier (especially to HDMI ports). Just another reason why effective appliance protection is outside and where all utility wires enter a structure.
