So , recently i flew in economy on Lufthansa 747 and United 767 airplanes, and i simply was not be able to charge my laptop . If
understood , our PSU require way more power then outlet charger on airplane can give , or it's was just only my laptop so weird??:mad:
In aiport , laptop was charging without any issue, but also only where was sing 110V .

It would not be so strange if the outlet you were using was bad, had a tripped breaker, something else along those lines. I would not assume off the bat it was something specific to the laptop or the power draw. Particularly if you were just charging the load wouldn't be that bad.

It would not be surprising if the plane(s) moderated their outlets' output. Considering the laptop charged fine at the airport, it would seem you don't have an issue with your brick or the laptop, at least. :)

Outlet was fine , due that guy who was siting near me was charging his HP laptop, when i plugged mine , power got scary of my 230 PSU (HP PSU was only 90w) , same was on another flight, macbook did got charged (alone with my old Samsung Chronos 7) my new Asus refused , so if anyway else was travel on airplane and WAS ABLE to charge 751 please reply what airplane and carrier it was , thanks

Outlets on planes are typically limited to between 90 and 120 watts. If the outlet senses any greater draw, it will usually shut down silently until the excess draw is removed. I have not tried to charge my 751 on a plane, but I have had similar problems with previous gaming notebooks. Thus, it is very likely that the 751 PSU simply draws too much even when just charging.

irablumberg, I wonder, if the 230w adapter trips the protection, maybe a 180w won't? - unless a 180w is what you were using. The 180w won't be enough to charge/play demanding games on a laptop that needs a 230w adapter for full power, but it might be enough to charge and watch a movie - and not trip the sensor on the AC socket. I haven't tried to fit a 180w on my G750JH - uses a 230w - but if it fits and runs it might be worth a try next time you fly :)

fyi. This will probably not be a good solution for most people, but it may be possible to charge the G751 battery while the unit is turned off since it should be drawing much less power, so for those that are taking very long flights, don't mind using the notebook on battery power, and can alternate between using the notebook (on battery) and turning it off (to charge while you take a nap?), this may let you get more use with the notebook during the (long) flight.

I do not see why the socket wouldn't work because at idle, the power drawn is quite low. Considering a moderate efficiency of 80% for the charger then at idle it would have drawn something around 40w/0.8 = 50W considering that at idle it consumes around 40W (From Notebookcheck's review). So, if the guy next to you could use his HP for wathcing movies or any kind of medium load, then yours should have worked either.
But on the other hand it might be some kind of protection that the charger itself has. Maybe the Amperage wasn't enough to power it because the voltage should have been anywhere between 100v and 230v because all devices work in this interval.

This is quite an interesting subject though :). I'm sorry that I can't say anything for sure.
