Thank you for sharing your knowledge. I would like to point out something that i found about the ACOK in the datasheet for U6000.
"ACOK : AC adapter detection open drain output. It is pulled HIGH to external pull-up supply rail by external pull-up resistor when voltage on ACDET pin is between 2.4V and 3.15V, and voltage on VCC is above UVLO and voltage on VCC pin is 275mV above voltage on SRN pin, indicating a valid adapter is present to start charge. If any one of the above conditions...Last edited by bridges_4u; 07-21-2024, 09:38 PM.

DK10FG-6050A2491301-MB-A03 missing ACOK
Hi there,
I have a DK10FG-6050A2491301-MB-A03 motherboard with missing ACOK voltage. Here are the basic voltages of BQ24725A. The motherboard is dead with no signs of life.
ACN : 19.35V
ACP : 19.36V
ACDET : 2.7V
REGN : 5.916V
VCC : 19.36V
Diode mode to ground reading on ACOK rail is 0.450V on pin 1 of R6013 and 0.230V at pin 2. Replaced BQ24725A a couple of times. Still no luck.
The problem was that I was not having 3.3V/5V from the TPS51225 regulator. So I tracked down to the BQ24725A which was missing the ACOK voltage...Last edited by bridges_4u; 07-21-2024, 12:50 PM.

Hi [USER="302067"]reformatt[/USER],
Thank you for jumping in to help. It has been a while that I followed up on this. I shall check for the above said voltages. If I am to replace the SMC, what sources can u recommend to buy donor boards?
[USER="295753"]mon2[/USER] has been helping me all this while and he is awesome. You too.
May i request you to take a look at one of my other threads. I shall post the link to that below.

Hi [USER="295753"]mon2[/USER]
YES. I am using the OEM 45watts Magsafe 2 charger.
R7012 : 68K. I had to replace this as it looked a bit off. But I substituted 0402 which is the only package size I got locally. International orders will take upto a month to arrive. So had to resort to this. Should I replace it with the same package size?
R7010 :100K
R7011 : 10 K.

Hi [USER="295753"]mon2[/USER]
YES. I do have the green light on the charger.
PPBUS_G3H : 12.40 V.
I shall post SMC_RESET_L voltages shortly as there has been a power outage.
