My Cold Cathode light went out of my laptop, so I replaced it. Well that wasn't the problem, so I am now replacing the converter for the Cold Cathode Light.
I am wanting to test the old light that I got out but I have a few questions. I have looked on the internet for the answers but I haven't really found direct answers to my questions.
First of all, Cold Cathode lights in laptops--do they run off of AC or DC? I am replacing the converter, but I don't know if it is a converter that turns DC into AC or that converts the DC into a higher voltage. I have found out that Cold Cathode lights take an extreme amount of voltage to power them--read in some places that they can be 600 to 1800 volts, but that the mA is extremely low, around 5 or so. Does that sound correct?
