Hello!
I need HELP.
I have a Lenovo Ideapad Y700 NM-A541 Rev1.0 and I just change the PCH and an IC from 1v because was short circuit. Now is powering on but no video. I noticed the VCCCPUCORE and VCCGFXCORE are missing.
My question is if the PCH may be to blame for these routes or if there is something else wrong. I can't find any direct connection between them.
PU402/403/404 - on the vcccpucore rail i have PIN1- 4.92v / PIN2 - 2.028v / PIN3-4.82v / PIN4 - 5.06v and is the same on PU405/406 form vccgfxcore.
Thanks
