Hello friends!
This is my 1st post, but unfortunately can not write in chinese language!
I got dell inspiron 15r3521 - platform : LA-9104P for repair, with shorted 19v line.
After replacing faulty PQ701 and PQ704, short is gone, and all voltages are Ok except +VCC_CORE and +VCC_GFXCORE_AXG (both=0V)
Changed PU700 Isl95833 with a recovered IC from another motherboard, +VCC_CORE is now Ok, but +VCC_GFXCORE_AXG is still absent (=0V)
VCC_GFXCORE_AXG Resistance to gnd=0.30hm (at coil PL700)
Flashed UH2 (EN25QH16) and UH6 (EN25Q32B) with dump file downloaded from this site, always same problem!!!
Any idea, what to do next ???
Is there a way (a tip) to test the +VCC_GFXCORE_AXG line without load of PCH HM76, so as to confirm whether output line has problem or HM76 ???
I think that reflashing IC kb9012 is not needed for this kind of issue. Do you agree ?
Thank you for any help!
