Just received a beautiful W530 Laptop - love the T and W versions of this machines. However, with such a large power requirement, want to make sure that I will be able to run and charge the W530 on United Airlines, American Airlines, etc., using the supplied 170 W Power supply...
Please confirm your experience that this will work. Otherwise, using this laptop on long haul flights will not work.

Can someone please help with this question? Hard to believe nobody has taken a W530 laptop on an airplane and whether the power supply operated the laptop (and did or did not charge the battery).
Thanks, greatly appreciate experience here.

It won't work with battery attached for sure; the seat power light will shut off once you plug it in.
You MAY be lucky if you disconnect the battery and/or use 90W power supply with a different resistor so that it fools the W530 circuitry into believing it's 135W+.
But if you want to be 100% sure to have power, buying a spare battery is the most reliable way to stay powered.

I have used my W530 with the 170W p/s plugged in on several Delta flights without problem. When the W530 is is not using the discrete GPU it does not seem to use a lot of current. When flying I generally use 2 or 3 instances of Word and/or Excel on my host, and between 1 and 3 VMs running development apps.

Is this based on your personal experience? Another poster says that it does work with Delta in seat power supply. If this laptop won't work on an airplane I need to repurpose....

Perhaps Delta has higher power limit, or ignores the initial spike, but I've never had any luck with W520/W530/W540/P70 (all with beefier than default GPUs) + battery and their 170/230W power supplies in cross-Atlantic flights with various non-US airlines. A spare battery fixes the problem for all but the longest flights.
In my experience, MS Surface Pro, or any other PC where you can put the screen on the table, and keyboard on your lap, is the best device for flying. That is, until all electronics larger than cellphone is completely banned, which is guinea-pig tested on some destinations now.
