do have a 820-3437 board,plug in charger
1. charger LED indicator orange,fan spin 2 second and stop.
2. PPBUS_G3H at F7700 pin 1 = 8.57v
3. PPBUS_S5_HS_COMPUTING_ISNS at R5450 pin 1 = 8.57v
4. PP3V3_S5 at U3560 pin 5 = 3.325v
5. PP15V_TBT at D3095 pin 2 = 0.00v
6. PPBUS_S5_HS_OTHER_ISNS at Q7560 pin 1 = 8.57v
so seems like there is problem with 15V boost is it?
1. PPBUS_G3H at C3080 pin 1 showing 8.57v
2. before i change Q3080 from scrap board,i get only 0.0v at L3095 pin 1,but after change from another scrap board,i get 7.90v at L3095 pin 1 and slowly decreasing.
what should i do next?
