I still don't understand why these elite models don't have a double m2 connection.

Ok but like what if you have the x55 wwan module and you got 2 antenna wires but 4 places to connect them. Is that WWAN card even one on the list of approved units?

@@HPSupport do you think there is a way to get working 8.1 or 7 drivers from like a dif model that works on a 840 g8

[@HPSupport]

We have not tested this and would not be able to comment whether it would work or not. Regards, HP Support

Having the keyboard built into the top cover instead of it being a separate piece was the dumbest decision ever.

Agreed. For a part with so many moving pieces that can fail so regularly, it's absurd it's not replaceable. I have multiple laptops out of warranty that have one or two failed keys and are thus garbage.
