To activate UMA mode, remove the following SMDs: PL1401, PL2401, PU2401, PU1401, PQ2401, PQ2402, PQ2403, and QV3. Then shift RC1609 to RC1610.

So I have this Sony VJF152C11N ( Board Number : DA0HKDMB6D0 ) which came to me with no charging issue. The Charging IC was getting hot so replaced it.
ISL88732 replaced with ISL88731 and also the lower mosfet PQ59 ( NTTFS4C10NTAG ) with a similar N channel mosfet. Now the Charging is fine with 15.7 on BAT+ line but the new problem is that laptop boots till sony logo and then shuts down when battery is connected ( With or without AC adapter )
What could be causing this is a non compatible IC or FET or poor soldering or some kind of shorting? -
