#1 Lenovo V520s - błąd wentylatora CPU (Error 0135)

Witam,
potrzebuję pomocy w rozwiązaniu następującego problemu.
Komputer: Lenovo V520s
Płyta główna: IB250MH Rev. 1.0
Po uruchomieniu komputer zgłasza błąd:
Error 0135: CPU Fan failure

Wentylator startuje normalnie i pracuje z jednostajną prędkością nawet po uruchomieniu systemu.

Co nie pomogło:
Podmiana wentylatora na inne 4pin (OEM Intel, AMD)
Reset ustawień w BIOS do ustawień fabrycznych
Reset BIOS przez wyjęcie baterii / zworkę
Aktualizacja BIOS do najnowszej wersji

Pomiary na pinach gniazda wentylatora:
wentylator podłączony:
1 - GND
2 - 12,0V
3 - 5,0V
4 - 1,2V
wentylator odłączony:
1 - GND
2 - 12,0V
3 - 10,0V
4 - 0V

Sprawdź oporność:
Rezystory R724 - 15kOhm
R699 - 7,5kOhm
R703 - 150 Ohm
Dioda D114 zmierz napięcia
pin 1
pin 2

Sprawdź diodę D73 - rezystancja\test diody między pin 3 a 1 oraz między pin 3 a 2

Zmierz napięcie do masy na pinie 4 kontrolera SuperIO (U33) w dwóch przypadkach - z podłączonym (działającym) oraz z odłączonym wentylatorem. Oczywiście pomiar wykonaj po włączeniu płyty.

R724 - 7,2 kOhm
R699 - 5,6 kOhm
R703 - 150 Ohm
D73 - test diody
(-) pin 3 -> (+) pin 1 - 0,765V
(+) pin 3 -> (-) pin 1 - 0,265V
analogiczne pomiary wychodzą z pin 3 do 2
D114
pin 1 - 0V (GND)
pin 2 - 3,3V (wentylator odłączony), 1,6V (wentylator podłączony)
@Vogelek23 - U33 pin 4 (z boardview wynika że połączony z D114 pin 2 więc pomiary jak wyżej)
