Dell Inspiron 5378 Charging Issue

[mgrharry]

Working on a Dell Inspiron 5378. Initially system had a short to ground. Injected voltage and found bad cap. Short gone, system powers on, but does not detect charger properly, despite known good dc jack and charger. It's a bit different from usual power id issue-- in bios it shows "AC Adapter Unknown" if power is plugged in but it also shows battery discharging and if AC is unplugged it does not update, still shows AC adapter unknown until system is rebooted. If powered up with no AC adapter it reports that correctly.

Photos attached.

MEC1404-Pin36 is PS_ID. Check whether you have voltage here or not?? Also resistance on this pin??
