Hey, Recently I have got this Dell Inspiron 3568 i5 7th Gen Vegas/Turis SKL/KBL 15341-1 91N85 *Battery is charging and LED is lighting when it's charging *5V_S5 and 3D3V_S5 are up *No short circuit in main power rails *No short circuit in any coils *When the adapter/power connected U4001 getting SIO_SLP_S3# and getting down to 0V immediately. *Power button switch getting 3.3v *When the power button is pressed SIO_PWRBTN# signal is not lowered to exactly 0V. ( This cause due to the immediate effect maybe) *X1802 Crystal is working *When the Adapter is plugged in SPI BIOS 7th pin transmits the data and also when the power button is pressed it's trasmitting. ----- *I have tried flashing many compatible BIOS but didn't help. *Check smaller caps and diodes, couldn't find any short circuit. |

I was removed PL5101, which is supply 1.2v for DIMMs and PCH, and when the adapter plugged in SIO_SLP_S3# 3.3v present. Secondary level power rails become active 3D3V_S0 and 5V_S0 also active. The 3-Amber and 5-White error code is also blinking. I have also checked resistance between the ground and PL5101 DIMM/PCH side, which is 377Ω (when PL5101 is removed). After removing PL5101 the RT8231AGQW side 360kΩ RT8231AGQW PU5101 (PL5101 removed) PGOOD-20mV TON-0.75v S5-3.3v S3-0v VLDOIN- 192mV VTT & VTTSNS - 0V VID- 5.12v VDD- 5.12v 3-Amber and 5-White LED error code is also blinking To make sure again PL5101 soldered and the adapter plugged in again SIO_SLP_S3# just come and go like a blink. RT8231AGQW PU5101 (PL5101 solder back) PGOOD-5mV S5-7mV S3-0v VLDOIN- 10mV VTT & VTTSNS - 0V (All these above values change into actual values for instance when the adapter is plugged in and back to these values) TON-17v VID- 5.12v VDD- 5.12v |
