Nice information.. Thanks

Thanks bro for sharing

Thanks for reply but There was problem in the VIN mosfet. My problem has been solved after replacing the mosfet.

I have checked and changed mosfet but still same. Another thing is that the Laptop is running OK on battery. If charger is connected with battery it shows charging but battery is draining instead of charging.

Hi all, I have dell 5537 la-9981p which have no power problem and B+ supply is 0.83V. There is no B+ supply generating from PU701 BQ717. I have replaced BQ717 but still there is no change in situation. Here is supply of BQ717. PIN 4 ACDRV = 19V PIN 6 ACDET = 2.5V PIN 5 AC OK = 3.5V PIN 20 VCC = 19V....

What is the condition of pin 3 and 13 of 51225 ic ?

I have searched for I/O whether its programmed or not but couldn't confirm about it. I don't have same board so I replace I/O with new one.
