Wow thanks for this link!! Post #50 by Jackal has a great workaround. Although could this be somewhat dangerous for the aircraft? Hmm....I don't want to be the cause of any electrical issues.

"So I think I've figured the secret out.

After forgetting my smaller adapters on my most recent trip, all I had to use was my 180W adapter.

Since it's the high-capacity capacitor that seems to trip the socket's circuit as soon as you plug it in, the secret seems to be that you need to let the capacitor in the charger charge up. Once it's full, the actual draw is usually less than 100W, so it's not enough to trip the circuit.

The way to do that is to repeatedly plug and unplug the charger into the socket (without a computer attached to the other end) until the light stays solid. Once the light is on solid, then you can plug your computer into the charger and proceed as normal.

First up was a VX A321. I plugged the adapter in and it went out, but the light on my adapter lit up a bit and stayed glowing. I plugged it in again and voila: all was well.

Next was an AS 738. This one was a little more difficult and required me to plug and unplug the power adapter about five or six times before it charged the capacitor enough to stay on. Once that happened, everything was smooth sailing.

Of course, if you are running right on the edge of the circuit's capacity such that a power spike in your laptop triggers the circuit to knock out, try putting the computer in sleep mode and charging the battery. Once the battery is full, then use the computer. That should reduce the power consumption enough to keep it below the circuit's max.

Edit: the AS 739 I flew last night took a good 10 or so plug-in-unplug cycles before it worked, but after that, no troubles at all."
