#1 Lenovo S540-15IML, płyta NB8606_MB_V4 nie startuje

Laptop jak temacie przyszedł do mnie z wyłamanym gniazdem zasilania (dwu pinowe) i rozładowaną baterią .
Po wymianie gniazda i podaniu zasilania płyta włącza się, pobiera ok 30 mA , jest 3,3 V oraz 5 v i tak zostaje .
Można wyłączyć przyciskiem power, wtedy pobór prądu maleje do ok 10 mA oraz zanika 3,3 V .
Ponowne włączenie przyciskiem power powoduje włączenie płyty , pobór ok 30 mA, jest 3,3 V i po 2-3 sekundach wyłącza się sam , pobór ok 10 mA , zanika 3,3 V
Pomiary rezystancji na cewkach :
PL201 - 1,4 Kom
PL301 - 44Kom
PL701 - 150 OM
PL604 - 6,2 OM
PL602 oraz PL603 - 3,6 OM
PL601 - 14 OM
PL501 - 46 OM
PL101 - 150 Kom
Martwi mnie dosyć niska oporność na cewkach PL602 i 603 , ale może już ktoś przerabiał ten temat i podpowie .
