- CC714 and CC715 (PP5V_G3S)
- C6523 (PPVOUT_S0_KBDBKLT_R)
- F3000 (PPDCIN_G3H and PPHV_INT_X_G3H)
after clean all those components. i tried to turn it on bust have blank display and always restart (based on chimes)
here are the measurements:
- PPBUS_G3H = 12.58V
- PPBUS_HS_CPU = 12.58V
- PPDCIN_G3H = 19.98V
- PP5V_G3S = 5V
- PP5V_S5_LDO = 5V
- PP3V3_G3H_RTC = 3.271V
- PP3V3_G3H = 3.271V
- PP1V8_G3S = 1.795V
- PPVCC_S0_CPU = 1.6V
- PP1V1_S3 = 1.095V
- PP0V6_S3 = 1.01V
