Model: Dell Inspiron 5559
Board id: Compal LA-D071P AAL15 Rev 1.0 (A00)
When connect adapter, laptop automatically running without pressing power key. Power comsumption on DC power supply is about 0.450 amp. Sometimes it's about 1.5 amp and then drop to about 0.450 amp. After opening 2, 3 times, PQ201 was shorted. So i Replace PQ201 and test again and after opening 2, 3 times PQ201 was shorted again. Resistance to ground on coils PL200 is 1 Ohm (with RAM) / 17 Ohm (without RAM). Remove PJP200, PLP202 and +1.35V_MEM side is 17Ohm and +1.35VP side is 78K (Wtih RAM). Need help.
PL100 - 3.3V
PL101 - 5V
PL1102 - 0.9V
PL1103 - 0.9V
PL601 - 1V
PL501 - 1.8V
PL200 - 0V
PL301 - 0V
PL603 - 0V
PL605 - 0V
Resistance to ground on coils
PL200 - 1 Ohm (with RAM) / 17 Ohm (without RAM)
PL301 - 44 Ohm
PL603 - 10 Ohm
PL605 - 10 Ohm
