#1 LENOVO V15-ADA, NM-D151 programowanie KBC = problem

Witam,

Mam laptopa LENOVO V15-ADA , który był już mocno dłubnięty przez jakiś serwis. Do mnie trafił z usterką wyłączania się po 35s. Nie jest to kwestia termiczna.

Płyta to NM-D151 REV 1.0 z KBC IT8227E-128 CXA z CPU AMD ATHLON GOLD Postanowiłem wymienić w nim KBC (stary nie komunikował się ze SVOD4) na nowy na IT 8227E-192 CXA - podobno kompatybilny z wersjia 128. Jednak na nowym KBC laptop nie uruchamiał się i nie programował się sam ani z poziomu KBC. SVOD4 wyrzuca IT SERIES NOT DETECTED. Postanowiłem więc wrócić do oryginalnego KBC, o dziwo po wlucie starego KBC laptop sie właczył i działał dłużej niż 35s, nie wyłączał się. Chciałem jednak zgarać wsad z KBC i tym razem udało się zakomunikować ze SVOD i zczytać tak mi sie przynajmniej wydwało zawartość KBC - później okazało się, że SVOD zczytał tylko kilka bajtów(2 linijki) a reszta pliku jest pusta. Sądząć, że mam komunikację i wsad KBC postanowiłem wyczyścić zawartość KBC i pozwolić zaprogramować mu się samemu lub później wgrać inny wsad wyciągnięty z BIOS.

Jednak na czystym KBC laptop nie programował się sam, późniejsze próby programowania ze SVODa kończą się niepowodzeniem, ciagle mam IT SERIES NOT DETECTED.

Gniazdo KBD - taśma - SVOD przedzwonione i mam przejścia. Schematu oczywiście brak by sprawdzić złącze KBD-KBC.
Wygląda na to, że procedura samoczynnego programowania nie działa na AMD?

Myślicie, że jest szansa to jeszcze ugryźć?
Z góry dziękuje za podpowiedzi

Cześć. Spróbuj wylutować kość BIOS i zobacz czy da się połączyć z KBC.

Niestety to juz też próbowałem i nie łączy sie.

Please, post a screen of Svod connections (Setup -> Edit motherboard).

I checked it, all connection are fine :?

Do you get a message "Check pins ok" in Svod, when you select the motherboard?

Yes, all green and check pin OK, also I checked connection between keyboard connector and SVOD connector.

In this case the first contact is on the right side (not left), if I'm not mistaken.
Change it and try again.

If the FFC cable is inserted into the connector on the board with the contacts on the top side, the first pin is on the Left side.

Did you connect the ground between the Svod programmer and motherboard and connect the power supply to the board?
If so, measure the voltages to ground on pins 12, 127 of KBC chip.

pin 12 -1.86V
PIN 127- 3,35V

The voltages are also fine.
It's strange that the Svod can't connect to this chip.

If you have any other board with a programmable ITE series KBC chip you can try reading it just to make sure there is nothing wrong with your Svod programmer.
If your Svod programmer is 100% fine, it's the best option to remove the KBC chip from the board and program it into the ZIF socket using the TQFP-128 Svod adapter.

I know that it's strange. Svod is fine, I have svod3 and svod4.

I bought ZIF socket I will have it in monday

Miałem ostatnio taki przypadek z tą płytą, że ITE nie chciał się komunikować ze SVOD-em 3, pomimo, że wszystko było 100% sprawdzone (połączenia, programator). Skomunikowałem się z układem dopiero po - uwaga - WŁĄCZENIU PŁYTY włącznikiem.

Witam temat wałkowany przeze mnie nie raz .... nie raz nie dwa nie mogłem nawiazać połączenia z różnymi płytami dopiero odkryłem że trzeba ją włączyć pwr sw i od razu odczytywać.
I to nie tylko w lenovo.
Szczerze to byłem pewny że tak trzeba właśnie robić :D
