I know that all surge protectors/upc's need outlets that have earth ground and be three pronged to safely protect against lightnings, but I would like to know if they can help against power fluctuations, even if just a little.
I have started unplugging my computer during rain and thunder storms but sometimes in my house the power fluctuates before any storm begins which causes my computer to shutdown or restart unexpectedly. If a surge protector can help in these situation then it would be worth using to to me.
