Hello,
MB: Acer GH4FZ LA-L202P Rev 1.0
Model no: Acer Swift SFX14-41G
My laptop has random shutdown during use no matter high or low loading since a year ago, but still can be restarted. One day, it got very hot at the bottom near the power chip (PUB1) during use, and finally shutdown when in use and cannot switch on again (like dead), so I suppose there is no major failures and power issue should be fixable.
There is no visual burnt or component damage, I tracked the power rail that the power seems blocked at charger chip (PUB1), measured some resistors value in surrounding are deviated a lot from schematic, however, after replacement the circuit still not working, need to further deep dive if any caps are shorted or IC failed but the schematic & board view I found online is different. The Rev 3.0 board view file has changed charger chip than Rev 1.0, so I would like to get a Rev 1.0 board view for better tracing the problem. Please help and thanks in advance.
