Re: Acer e1-431 dead no power led, no PWROK_EC
S5_ON still 2 5v, even though kbc are removed, in multimeter when set buzzer mode it doesn't show any short.
R141 also good (it measured 10K, same like schematic)
PCH_RSMRST# still 0vLast edited by crot69; 08-10-2023, 02:49 AM.

VIN = 19V
3VPCU = 3.3V
5VPCU = 5.1V
MAINON = 6.35V
MAIND = 0V
15V = 13.5V
15V_ALWP = 13.47V
S5_ON = 2.5V
+A3VPCU = 3.3V
+3VPCU_EC = 3.3V
ACIN = 3.3V
RTC_RST# = 3.3V
+3V_RTC = 3.3V
S5D = 0V
BATLED0# = 2V
BATLED1# = 1.5V
NBSWON# = 3.3v, when pressed 0v

Re: Toshiba C640 no charging
After resolder charger led on but no charger voltage from inductor (low side charging mosfet gate 0v, resistance 23Mohm and high side charging mosfet gate only 10.43v, resistance 30Mohm and my battery voltage is 10.96v = 0%) also LDO 5.25v but after resistor R6007 only 0.24V...Last edited by crot69; 01-03-2023, 11:23 PM.

Re: Toshiba C640 no charging
Maybe bad ic connection, i see it not fully filled with tin
And DLO pin show OL when resistance mode and 0v when plug a charger

asus x453sa missing all voltage except 19v and charging pin
Hi, my friend have this laptop
Before all voltage missing, im already repair this laptop 3x (i have 3 of this laptop and all of them dead, can't be repaired because dead CPU and other component due unknow chips, why always asus laptop have this issue).
1st repair it short at 3vsus (dead low side mosfe and short caps)
2nd repair short at CPU Vcore mosfet (low side)
3rd repair 12v missing (only 1.2v but it can run bios and hdd not detected because 3vs missing).
and then after 3x enter BIOS it blank then dead (all mosfet buzzing, 12v still missing)
