I have that very same one from AliExpress. No, it does not work.
It gets power for a few seconds on the +5 VDC USB lane, then shuts off completely after POSTing (no data, no current).
So it seems that it is "hardware"-compatible, but disabled in BIOS like all other possible mini-PCIE devices, except for white-listed network cards.
Kinda strange, considering that the very same Mini-PCIE gadget worked fine on a Acer Aspire One NAV-50 netbook (a very very very cheap machine )
So damn true, the 2570p is bit heavy...
About the charger - last year about 20-30 chargers went through my hands, my impression was that Watt capacity was very tightly related to weight. That is, a charger gotta weigh at least that and that grams for 65W, that and that grams for 90W and so on.
