Voltages come and go as the device turns off and on. PP3V3_UPC_TB_LDO = 3,3 volt PP1V8_UPC_TB_LDOA =1,8 Volt PP1V8_UPC_TB_LDOD = 1,8 Volt PP1V1_UPC_TB_LDO_BMC = No voltage

same response on all connectors

hello, 820-00239 won't turn on after fall 5v was drawing 265 amps. CB408 was showing short circuit when I checked. I disassembled the CB408. No more short circuits. but keweisi opens and closes. it shows 5v

I tried with a full battery, it won't turn on. I replaced UB300/400, same result. When the battery is not plugged in, the jb500 side gets 5 volts. But when the battery is inserted, it turns to 19 volts. The device does not charge and does not turn on. It's 19v when the battery is plugged in...

Does having these voltages mean that the ub300/400 is working or isn't ? So even if I have these voltages, is there a possibility that it is still faulty? PP3V3_UPC_TA_LDO / CB308 = 3,4 Volt PP1V8_UPC_TA_LDOA / = 1,7 Volt PP1V8_UPC_TA_LDOD = 1,8 Volt PP1V1_UPC_TA_LDO_BMC = 1,1 Volt...

I'm sorry it stayed like that while translating :) I installed UB090 from the same board and it stays at the same 5volts. Can we say that the ub300/400 is solid because the above voltages are?

it doesn't restart right now it's pulling 0.64a won't boot PPVIN_S0_CPUAXG = 8.36v PPVCORE_S0_AXG_R = No Voltage CPUIMVP_PHASE1G = No Voltage CPUIMVP_LGATE1G = No Voltage CPUIMVP_UGATE1G = No Voltage PPVCORE_S0_CPU_REG = 0.75v PPDDR_S3_REG = 1.3V PCPUVCCIO_S0_REG = 1 Volt PPVCCSA_S0_REG =0.78...

what will I do :)

5 volt çevriminin UB090 ile bir ilgisi var mı? Başka karttan değiştirdim yine aynı

PP3V3_UPC_TA_LDO / CB308 = 3,4 Volt PP1V8_UPC_TA_LDOA / = 1,7 Volt PP1V8_UPC_TA_LDOD = 1,8 Volt PP1V1_UPC_TA_LDO_BMC = 1,1 Volt 1PP3V3_UPC_TB_LDO = 3,4 Volt PP1V8_UPC_TB_LDOA = 1,8 Volt PP1V8_UPC_TB_LDOD = 1,8 Volt PP1V1_UPC_TB_LDO_BMC = 1,1 Volt what else do i have to check

I checked the LDOs lines, no shorts I checked all the parts near the ub300/400 with gnd there is no short circuit How can I narrow the field?

20v when I plug it into the j3300 side and 5 0.29a volts when I plug it into the jb500 side

SMC_BC_ACOK : 3.4 Volt

I checked again this morning and saw 20 volts instead of 5 volts on the keweısı. But the amperage drawn is 0 when I first plug it in, it draws 0.17a and then it drops to zero. No original charger. I tried it with its own battery, it didn't charge. The charger I am using now creates all voltages...

Soryy CHGR_AMON = No Voltage R5439 CHGR_BMON = No Voltage R5429 No problem with R7021/22 resistors and R7021/22 = 5 volt

P_IN = 5.1 Volt AUX_DET = 1.2 Volt VDDA = 5Volt VDDAp = 5 Volt EN_VR1 (R6921) = 5 Volt SMC_RST = 3.4 Volt AUX_OK (Q5490 pin2) = 3.4 Volt (D4)AMON CHGR_AMON = 3.4 Volt BMON CHGR_BMON = No Voltage R3038 SMC_USBC_INT_L = No Voltage big coils are not short circuited diode mode PPBUS_G3H = 0.406

VDDA pin shows 100ohm with gnd. When I check the same pin on another board, 500ohm appears. Could the u7000 be faulty? I replaced the U7000. It draws 5v 0.029a right now (R6923) PP3V3_G3H= 3.4 volt

hello, Flux traces in the u5000 and u9800 region same 5v on all dc inputs I removed the D6902 and read 5 volts on pin 1 again. PPDCIN_G3H_CHGR = 5 volt

I changed u7201. SMC_PM_G2_EN = 3.4 Voltage fixed It was a fan return. It pulls at 0.62a and after 15 seconds it turns off and on again. I tried SMC pypass mode. The fan is spinning at full speed. It resets again after 15 seconds. I transferred the bios from the same motherboard, still the same
