Hi,

Is it the WWAN card ? If yes then it won't work because this is a different architecture and this slot is suitabale for WWAN card only.

hi and thanks for the answer.

are u sure?

because at the service manual http://h10032.www1.hp.com/ctg/Manual/c05270979
only noted in page 42 is : The WWAN module and the WLAN module are not interchangeable.

The Slot is idendical for m2 installation as show at page 44.

Thanks for your help:)

As mentioned of my first reply, the slot uses different socket. There are 3 types

Different socket types are part of the M.2 specification that requires support for specific device types within a given socket.

Socket 1 is designed for Wi-Fi, Bluetooth®, NFC and WI Gig

Socket 2 is designed for WWAN, SSD (caching) and GNSS

Socket 3 is designed for SSDs (both SATA and PCIe, up to x4 performance)

Yes, the WLAN and WWAN are not interchangable because they use different socket. But socket 2 is not suitable for SSD's even it has same connection layout. Your Sandisk M.2 is designed to use socket 3.

Hope this makes sense.

Regards.
