#1 ACER E5-773 - dołożenie slotu m2

ACER E5-773
Płyta: 14276-1M Brook_BH MB
APU: i3-4005U
KBC: ene KB9028Q C

Płyta bez fabrycznie zamontowanego gniazda m2 ("MSATA1"). Posiadam drugą płytę z uszkodzonym apu i gniazdem m2 na dawcę.
Przeniosłem z dawcy na sprawną gniazdo m2 (MSATA1) i drobnicę w te same miejsca: R6304, EC6301, C6310, C6306, U6305, C6318, C6317, C6307, C6308, C6305 oraz Q1902.

Niestety płyta nie widzi dysku m2 (m2. sata ani pcie, zależy mi na M2 SATA, bo taki mam dysk).

Coś pominąłem?

Do zamontowania jeszcze: C6309, C6320 (oba 100nF/16V) oraz Q1902 (2N7002KDW).

C6309, C6320 zamontowałem.
Q1902 też.
Dysk M2 nie jest widoczny.

Na schemacie jest tabela, jak ją interpretować?

Po zamontowaniu dysku na MSATA_PEDET mam 0V, czyli stan niski.
Bez zamontowanego dysku MSATA_PEDET= 3V, czyli stan wysoki.
Mierzone na obsadzonym R6304 (1MOhm).
Tak powinno być?

Całkiem normalnie - sygnał MSATA_PEDET jest w stanie niskim, gdy w slocie jest zamontowany dysk SATA, a w stanie wysokim (podciągnięty do 3D3V_MSATA_S0 przez R6304), gdy w slocie jest dysk NVMe. Czyli masz tak, jak powinno być. Sprawdź na pinach 3 i 6 tranzystora Q1902, czy masz na obu 3V gdy w slot włożony jest dysk SATA. Jeśli nie - sprawdź, czy masz zamontowaną drabinkę RN1712 (4x 10kΩ).

Q1902:
pin3 = 3.36V
pin6= 3.36V
pozostałe = 0V

RN1712 (10kOhm) jest obsadzony, pin6 =3.36V oraz pin8 = 3.36V.
