push the button aaaannnnd-- nuthin. Now what?

Normally when that happens its bc the mosfet starts to fry and gets hot enough that it actually breaks the connection. That's why I said its prob a mosfet issue since you described it as the button would still light up, but has no power output. That's what normally happens when you fry the mosfet on an eGo. Two of my friends had the same thing happen, so that's why I figured it was bc of that since they had the same thing happen. Frying the mosfet is a LOT more common when you use something like a 1.5ohm or 1.7ohm carto on an eGo, but technically using a 2.0ohm carto can cause the same problem, it's just alot less likely to happen, since a 2.0ohm carto doesn't stress the mosfet like a 1.5ohm or 1.7ohm does. But it looks like for your eGo, a 2.0ohm was enough to start to fry the mosfet.
I was going to recommend that you could take it apart and resolder the broken wire, but I didn't bc most people either don't know how to do it or don't have the tools to do it. I resoldered both of my buddy's eGos for them that had the same problem and their both still working fine again.
So I'm glad you were knowledgable enough to try to fix it and were able to bc it's really not that hard to do. Most people just throw them out bc they either don't want to bother with it, or dont know they can fix it. So I'm glad you were able to get it going again, and now you know for the future how to fix one if it happens again

Fried mosfet, huh. I think that's what happened to my first two egos. They smoked out of the button and stopped working altogether. Plus they still stink like burnt plastic 3 months later. This one had no symptoms of burning up. Just no fire to the structure. Now it is all good.

Structure? WTH? Atty. Damn autocorrect.

Haha gotta love autocorrect.
Yeah the eGo is a mosfet driven PV and that's one of the reasons I dont recommend using below 2.0ohm cartos on an eGo. Some people do use below 2.0ohm and never have a prOblem, but theres also alot of people that have fried an eGo using them. The lower the resistance, the more stress that is put on the mosfet. 1.5ohms are the most likely to fry the mosfet, but it can also happen with something like a 1.7ohm. So if you do use them, be careful, and I also wouldn't chain vape with them. Chain vaping causes the internals to get hot, and using a real low resistance causes them to get hot even faster. That can lead to a fried mosfet at the worst, or like what happened to you, it doesn't push it far enough to totally fry it, but it gets hot enough to break the connection

What would happen if I took all of the electronics out and rigged up a mechanical pv, using the old ego batt and a new switch? I have these two dead egos just sitting here begging for me to do something with. Could I still charge using a standard ego charger, or would I need a special one?
