Without SMC_Adapter_EN 2936

[MDY]

SMC_Adapter_EN at =0V board should work only with battery? It is 820-2936

Useless info. PPBUS? 3V3_S5? Liquid? Green light?

Board is already repaired. I replaced smc. I had smc adapter at 0V and it works with battery only sometimes. Never with adapter. Thats way I had this question.

 

[MDY]

Well, it is not repaired. PPBUS - 12.56V. It works only with ac adapter.
With battery doesnot power anymore. I checked 3V on keyboard connector pin-5 and goes to 0V when press power. Also tried with new keyboard. After I replaced SMC it power with keyboard and battery plued 3 times and charges battery to 10% but now it power ONLY with ac adapter. Could be bad soldering or bad SMC?

Battery recognized? Disconnect battery indicator to rule that out.

 

[MDY]

Battery is recognized and charges also. Indicator is not connected. What is next? Replace SMC again?

Here is the history:
I recived the laptops working only with battery. Only with ac adapter no green light and doesnot power. I heat SMC and I got green light and works only 1 hour. Then I replaced SMC and now works everything except to power the board with keyboard. I power the board with battery and then I plud the battery in hot and all is ok.

Pin 7 on u5010 going low when you press power button?

 

[MDY]

Yes, it goes low.

 

[dukefawks]

No idea, as it worked with the other SMC I suspect another SMC issue. Did you replace it with a donor SMC from a 2936 board?

 

[MDY]

Yes, it was 2936. Will replace smc again. 3115 is compatible to take smc?

Completely different layout.
Read the codes, then check for SMC stencil for both; you will understand...

 

[MDY]

I repalced SMC again and know power with button too. Will test 1 day more. Last time it worked ok after SMC replacment only 30 minutes.
