The not grounded red light is on in the two holes wall outlet,but is not on in the three holes wall outlet.
I just bought a Beklin surge protector power strip. It has the surge protector and not grounded light. Now, I have two wall outlets in the same room. One wall outlet has two holes plug in, the other one is three holes plug in. When I plug the surge protector in the two holes wall outlet, the not grounded light is on, when I plug the surge protector in the three holes wall outlet, the not grounded light is not on. So, dose, the two holes and three holes wall outlets make it grounded or not grounded,or it's more than that?

Well that is basically what it is.

How are you plugging it into a two-prong receptacle? Doesn't it have a three-prong plug?
