Laptop: HP OMEN 15-dc0005nw
Płyta: DAG3DBMB8D0 Rev: D

Proszę o pomoc w diagnozie płyty. Po podłączeniu zasilacza (mam 90W oryginalny HP) zapala się dioda zasilania. Dołożenie baterii czerwona dioda. Na zasilaczu serwisowym pobór przez chwilę to 34mA a po sekundzie/dwóch spada na 13mA. Klawisz włącznika 14mA po czym spada na 13mA.

Poniżej pomiary na wpiętym zasilaczu HP bez baterii:

PL151 5VS5_LX - 5V ~5kohm
PL3 BQPHASE - 3.17V 50kohm
PL101 3VS5_LX - 0V / ~5kohm - pojawia się 3V3 na sekunde/dwie po podłączeniu zasilacza.
Reszta dławików 0V.

PL501 +1.05V_DEEP_SUS - 50ohm 0V
PL201 +1.2VSUS - 500ohm (bez RAM) 0V
PL601 +VCCIO - 50ohm 0V
PL401 +VCCSA - 15ohm 0V
+VCC_CORE - 2ohm 0V
+VCC_GT - 4,5ohm 0V

Napięcie na włączniku jest, spada do 0.3V po wciśnięciu.

Po podłączeniu zasilacza delikatnie się grzeje układ PU101 (przetwornica 3V RT6256B) w momencie kiedy znika 3V3 na dławiku PL101. Miałem taki układ, zmieniłem ale jest to samo. LDO 3V produkuje, PG 0V, EN jest tylko świeżo po wpięciu zasilacza.

Proszę o instrukcje co sprawdzić, BIOS robiony - bez zmian.
