Random SSD disconnection errors (3F0 > no harddrive installed)

[HappyCostumer]

My HP laptop 15-cs2000nd randomly fails to boot from time to time. 

When this issue first transpired and the harddrive test failed, I opened the case and to my amazement the 256gb SK hynix NVMe SSD just fell out. It was probably never screwed on... So I reseated the SSD and screwed it down properly, thinking I solved the issue.

However the laptop continued to fail booting. Then I bought a new 256gb NVMe SSD thinking the default SSD just failed. When the new SSD was installed, it was recognized directly and I installed windows 10 on it thinking my problems were solved. But now the laptop still fails to boot 50% of the time with the 3f0 error. 

I followed all the steps of this thread: https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/SSD-seems-to-be-disconnecting/...

What can I do? 

Thanks in advance,

Cédric

Okey so for you all wondering, I screwed the old SSD in, but this time a bit more firm and it worked. Everything is solved now
