HP ProBook x360 435 G8 and SSD ADATA XPG 8200 Pro 2TB

Hello!

I bought brand new ADATA 2TB ssd to replace installed 1TB Micron ssd, which worked perfectly, just need more space.

Problem: after 1-4 hours of normal functioning system randomly crashes, to be exact, laptop just loses ssd literally. OS tries to do BSOD dump, but at this moment there is no storage to write dump. Next it restarts and greets me withF03 error (boot device not found) and offers embedded diagnostic tests. On next restart (soft, don't even need cold restart) ssd is visible again, bootable, and everything is fine until next crash happens. If I put WinPE recovery usb stick and wait for crash, laptop on first restart will boot to WinPE and it will also show me that there is no ssd in system. Until second restart as described above.

I did all kind of diagnostics, including HP embedded, checked new ssd for bad sectors, smart, etc - everything is OK.

If to put back old ssd - laptop works flawlessly. I found another HP laptop of older generation with Core I7 8xxx series and new SSD works on it without any problems, no single crash.

I reinstalled OS and drivers, no effect. UEFI firmware is latest available, 1.11.something, wih reset to defaults just in case. ADATA toolbox shows that firmware is also latest, there is no overheat, chashes happen in idle mode with 36C temp, on workloads, on sleep, on hibernation... I think i checked all scenarios.

Any ideas and suggestions would be appreciated.

Found similar problem https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/SSD-seems-to-be-disconnecting/... without solving. Looks tha i've ended up with working laptop and working ssd but without working them together.

Also found one suspicious difference between old test laptop and my x360: test laptop supports and uses S3 sleep mode, my laptop uses abominational modern S0 state which cannot be switched to normal sleep mode, firmware does not support S3.
