Insert the M.2 drive at a 45° angle

The M.2 socket has a divider that must be aligned.

Gently press the M.2 drive down with your finger.

Hold the M.2 drive down with a finger on one corner, and engage the blue latch with the second finger.

The M.2 Drive is retained by a spring, and requires the latch to hold it in place for proper contact.

Inserting and retaining the M.2 drive should not require force, it should slide in easily and require very little pressure to hold it in place while engaging the blue latch.
