ASUS FX504GM DABKLIMBAB0 revC prob with EC or chargerIC
Hi, such a problem, the laptop after an unsuccessful firmware update, the dump was dirty, I flashed the dump (from the offsite), the laptop turns on and the battery charges everything seems OK, but if the power supply and battery are connected at once, then the touchpad freezes and the OS loads long time, but if you work only from the battery or only from the power supply then everything is fine and fast, and there is also a problem that when you disconnect rtc and turn off all power, the asus boards should have an auto turn on, but it does not... also, if you turn on the laptop from the button... -

Re: Lenovo ThinkPad X1 yoga NM-B861 not have 20v
i change q196 but it didn’t help, I forgot to write that when the battery and the lab power supply are connected, the current is 2.10 amps and the charging circuit is heatedLeave a comment:

Re: Lenovo ThinkPad X1 yoga NM-B861 not have 20v
if you connect only the battery and press the button, all the power voltages appear that I wrote about earlier but for a few seconds and not have voltage on L5, but if you connect the battery and the power supply, then there are 16 volts on the L5 coil and the charger area and q281 warm but there is no reaction pwr button, I don’t like why it’s warm charger but mostly warm mosfets q281 q282 q196, i will try to change q196... is so redicilious if the battery is connected and the power supply has 16 volts on the l5 coil,...Leave a comment:

Re: Lenovo ThinkPad X1 yoga NM-B861 not have 20v
1 U196 REGN pin = 6.092v
2 U196 ACN pin = 20.16v ACP= 20.16v
3 Q281 source 2-3-4 = 20.16v
4 Q281 gate pin 1 = 0.457v
5 Q281 gate pin 8 = 5.923v
I replace new mosfet not from donor board.Leave a comment:

Lenovo ThinkPad X1 yoga NM-B861 not have 20v
Such a problem when connecting type c, the power button flashes three times, after Q281 AON6996 dualmosfet not out 20v on L5, this voltage is low 0.432v and there is only TPS51393PRJER 3.3v on L135 VCC3M there are no other voltages. I changed Q281 charger BQ25700 also flashed ec but it didn’t help....Last edited by misha97123; 03-03-2023, 06:36 AM. -
