Thanks for your answer but unfortunately the same State...
Please give me important signals to measure tham
right Now ihave:
vin:19v
+3VPCU +5VPCU in stepdown section
Pin8 of bios: 0v
RSMRST: 0V
if you have schematic for this board please give it to me....

i think schematic not available for this model

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

Is the mb switching?? If so, then measure voltages at all coils first and report. There are lot of experienced members here who can help.

Thank you mcplslg123 very much

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

Vin in SIO:


EC:
PIN1,PIN2,PIN3,PIN4,PIN7:0V (GND)
PIN5,PIN6,PIN8:3.3V
BIOS:
ALL PIN : 0V
Please Help me.... WHAT CAN I DO..

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

It seems you have 3VALW And 5VALW at coil. 3V AALW should go to sio and from there you should get 3v at power button. Check SIO for corrosion,shorting or any componenets which looks suspect. Check 3 & 5v SUS voltage

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

SIO is getting 3VALW but One of SIO vin pin 88 there is no voltage Normly we get 3.3v there
and this pin is directly related with pin 8 of bios chip and other comp.
maybe there is a short
the resistance of this pin i get 10 ohm
3 & 5v SUS voltage available in the tow mosfet

Where are you please help

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

Did you check pin 88 of SIO chips has continuity with other pins or 3VPCU_EC line?
Maybe line of 3VPCU was broke inside layer of PCB.
Did you measure resistance with plugged adapter? if pin 88 have connect to pin 19, 46, etc, could be the IC (RT6575A) get warm or hot

- Only one of 3 ICs (RT8068AZQW, with mark 13, PU4, PU5 and PU6) should be have voltage 1.8VPCU. Read schematic Quanta ZHK or ZQM. Easy to finding on google or s-manual
- I don't see IC charge pump (G5934RZ1U) for load switch, maybe only use double of Diode as charge pump.

Thank you very much, man for helping me with everything clear I will measure...right Now
to be continued... thank you agane

Re: need bios dump (EC+MAIN ) of toshiba C55-B1336

After a lot of test this is result:
I measured resistance with plugged adapter pin 88 with 16.46.... i get 52.5OHM
Voltage Existe:
+3VPCU
+5VPCU
+5VS5
Voltage NO Existe:
+1.8VPCU
+3VS5
*** And i get S5_ON VOLTAGE IS: 2.56V Is it normale
