Laptop turns off when i unplug
I have an Inspiron 7568. I recently had a water spill accident on the keyboard. The laptop immediately switched off. I then took out the back panel and removed the battery, hard disk, etc, and let the laptop air dry for a day. After that, the laptop turned on again and worked normally except for one issue. When I unplug the laptop, it no longer switches to battery power - it just turns off. I have already checked the battery health - it is excellent and currently holds >70% charge. I have tried the usual solutions like taking the battery out and pressing the power button on for 30 seconds, etc. I read somewhere that the switching MOSFET has been damaged - could this be the case? If so how can I identify where it is and find a replacement? Or could there be some other different reason altogether?
Although the laptop works well with AC power, it is annoying because if the charging cable accidentally becomes loose, the laptop loses power. Thank you!

Unless you examine the board closely with a magnifier and find the clearly-blown component or corrosion, there is no real way - and even if you do find a faulty component, sourcing some of these may not be easy (and you have no guarantee the damage is just that one IC, diode, etc.).
The only sure solution -- and likely the ultimate one if a cursory repair fails -- is a replacement system board.
