trafił do mnie laptop Acer Nitro 5 AN515-56 Compal GH52T LA-L051P. klient sam sobie wymieniał matrycę i niestety nie odpiął baterii więc laptop przestał się uruchamiać. po szybkiej diagnozie jest reakcja na włącznik, pojawia się napięcie 3v i 5v pobór prądu około 0,052A. Brak jest napięć 3VS i 5VS, brak SUSON, brak VR_PWRGD i wydaje mi się że jest małe zwarcie na napięciu 3VALW po pomiar do masy wynosi 30 ohm, ale napięcie jest i nic się nie grzeje.
Podejrzewam że hybryda została uszkodzona, ale może wasza pomoc przyniesie inne wyniki.

Hello!
Yes, this resistance is definitely too low. Open the jumper PJ302 and measure the resistances to ground on both pads of this jumper.
If the low resistance is present on the system side (power rail "+3VALW"), also open the jumper JPC1 and remeasure the resistance to ground on the power rail "+3VALW".
