#1 Lenovo Thinkpad P53 płyta nm-c261 błędy grafiki po podłączeniu zasilacza

LAptop na baterii działa prawidłowo ( głównie gry ) lecz po podłączeniu zasilacza wywala błędy dotyczące grafiki, direct X lub blue screen i wentylatory na maksymalnych obrotach. Płyta wyciągnięta i jak się podłączy zasilacz to mocno się nagrzewają układy PU4, PU5, PU6 i PU12, PU9 trochę mniej wraz z cewkami PL6, PL7, PL8

Napięcia bateria/ bateria + zasilacz na tych cewkach
PL6 1.1V / 1.1-1.2V
PL7 1.1V / 1.1-1.2V
PL8 1.1V / 1.1-1.2V
PL11 1.1V / 1.1-1.2V
PL10 0.9V / 0.9V

Rezystancja na tych cewkach
PL6 3.8Ω
PL7 3.8Ω
PL8 3.8Ω
PL11 3.8Ω
PL10 25.4Ω

Co mogę sprawdzić ? z góry dzięki

Hello!

Measure the voltages to ground on both pins of resistor REC70, when the machine is turned on with the power supply connected.
