Hp Probook 450 - G2 M2 Ssd Compatibility ((install))
Real-world testing by enthusiasts and IT professionals over the last 8 years has confirmed a much wider compatibility list, provided the drive meets these three criteria:
: You must use a 2242 size drive (22mm wide by 42mm long). The more common 2280 (80mm) drives are too long to fit into the designated space and cannot be secured.
The slot in your laptop only accepts drives that are 22mm wide and 42mm long (the "22x42" or "2242" form factor). A longer drive, like a common 2280 (80mm), simply will not fit. Crucially, the ProBook 450 G2's M.2 slot is designed for the M.2 WWAN (mobile broadband) card, and only a short 42mm SSD can fit in that space . The service manual clearly states the drive is located near the Wi-Fi card.
