Witam wszystkich,
Dell 7410, płyta LA-J261P Rev: 1.0
Najprawdopodobniej laptop uszkodził się po zwarciu w porcie USB-C.
Na linii +3.3V_ALWP, +5V_ALWP oraz +3.3V_VDD rezystancja ok 10Ω.
Próba zwarciowa wykazała uszkodzenie UT5 (TPS65988DJ) oraz UT1 (Intel T803A900 JHL7540-SLMHS). Po usunięciu układów z płyty rezystancje wróciły do normy.
Pytanie teraz brzmi czy jak zakupie nowe układy, to trzeba je zaprogramować?
Czy nie trzeba ich programować, oprogramowanie pobierane jest z układów SPI UT6 i UT2?

Hello!
No, neither of these two chips requires programming. You can just replace them with new ones.
