RS130 no connection anymore internal SSD

Hi there, i have noticed that SSD volume is not seen anymore in my RS130.
Removed all plugs and pull off the SSD and back again.
Fresh boot after that, no SSD.

I bought another new Samsung EVO SSD with 1TB, installed it 30min ago.
No SSD.

I never believe 2 SSD‘s are defective.

My RS130 got a new lcd screen some weeks ago, by warranty.
I can‘t remember if i used SSD volume before or after this warranty issue with the lcd screen.

Question : Is it possible somebody forgot to plug an internal cable due to SSD connection during the work replacing lcd screen ?

How to fix ?

Thanks, Christian
