Good Day.
I have received an Dell Alienware 17R4 which is faulty and will not turn on,
Intel Core i7 7700hq, Gtx1070, 8Gb, The laptop i got yesterday in pieces, I have tested the motherboard, Test Results
19V present, 3.3v, 5v present,.pwrbtn 3v present, bios chip 25q128 has o voltage and further no other voltages are present, power button press reacts and 3.3v and 5v goes on and off when pwrbtn pressed.
PCH3.3v and bioschip 3,3v was missing before and after pwrbtn press so i replaced ENE KBC,. with another from dell alienware 15R3,. After replacing kbc, i got 3.3v on pch and all bios chips,
now when i press the power button the board goes on and off for 3 times, and then stays on but cpu, gpu, memory volatges go off,
when i press pwrbtn and then test voltages, then cpu vcccp, vcore, comes on, memory, gpu ram etc 1v, 1.8v simply all voltages are but after going on cpu vrm, gpu vrm and memory vrom goes out,
no short, no liquid etc,.
Thanks
