#1 Lenovo ideapad 3 NM-D031 nie działa z RAMem w slocie

Witam,
Ideapad 3 14IIL05
Płyta NM-D031 Rev 1.0
Laptop raz wyświetlał obraz, raz nie. Kiedy pojawiał się obraz występowały takie rzeczy i freeze.
Image
Po rozebraniu i wyjęciu pamięci RAM ze slotu laptop działa stabilnie na pamięci wlutowanej.
Włożenie jakiejkolwiek pamięci w slot (test na DDR4 4GB, 8GB...) powoduje uruchomienie z ciemnym ekranem.
Na testerze DDR4 nie świeci się dioda VDD oraz CKE0
Image
P. S. Posiada ktoś jakąkolwiek dokumentację/poradniki do tych testerów? Nie wiem za bardzo jak je interpretować.
Wstępnie piny od slotu przejrzane, wyglądają na czyste i żaden się nie rusza.
Image
EDIT: porównałem ze sprawną płytą NM-C711 - dość podobna budowa. Tam świeci się sygnał CKE0. VDD domyślnie się nie świeci (nie podłączone zasilanie?)

Podobno najciemniej pod latarnią. Zdjąłbym kropki kleju i sprawdził jeszcze te piny.
