I am a sucker for a good deal. Recently there was a city auction for a Gateway Profile 4. They actually had two but I lost the auction for the second one. It was cheap because it didn't work. Looking it over I discovered it was the inverter. I wish I could have gotten the second one and parted it for this one. Anyway I've found a numer of sites that take about this (The inverter problem is a common problem with this).

Here are some sites I found that have been helpful

If fact these sites inspired me to start this blog. Anyway on my inverter I figured out it was the transformer. I pulled it out and the lead wire was burned out. I tried to solder it back but the lead to the wire was epoxied and my attempts to get a connection to it only led to a shorter and shorter lead wire. Sigh.
