Hello - all my apologies if this is the wrong thread. I fly on United a fair amount in Biz class and I am consistently running into power issues. It seems like the power plugs in biz class (I have not tested this in econ) on 737 and 757 planes do not like my laptop brick (135W & 7 amps). I run out of power too quickly on my stupid laptop. The green light on the biz class power goes dark when I plug in my brick. Is this normal?? On the 787 and 777 - in biz and econ - they all work 100% FINE.

TIA!!
