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.
B+ SUPPPLY is only 0.83V.
kindly help me to solve the problem.
Thanks

Check B+ on short circuit. Measure the resistance B+ to ground

There is no sorting. laptop is working on Battery. If charger is connected with battery it shows charging but battery is draining instead of charging.

Replace first MOSFET from DCIN.

Thanks MSF113..

There was problem in VIN mosfet. My problem has been solved after replacing the mosfet.
