I have a question because an faulty switch i have checked anything and my friend tell me its brocken after change the case. I have checked anything and have found 1 capacitor that shortet. Becauee of that I have changed the M92T36 chip there is nothibg change on the capacitor. The BQ24193 chip will heat up that I cant touching after i plug it to charge. Charging funktion with 15v by 0.22A or 4.96V by 0.46A. I dont know whats wrong all capacitor on the BQ chip are okay.
The capacitor way (pin of the M92T36 and the capacitor is okay) on the backside the capacitor ist okay but how I can test the EN ? And if I gorgt it to say i after i have remoced the M92T36 the capacitor was shortet too withozt thr M92T36 chip
Check if the diode mode values are similar to those on the picture. If the right side of the cap shows something around 620mV I would expect that the EN isn t effected from the short in the VDDIO line.
I would check the display connector for bend pins.
Before calling the Switch dead, I would check farther. This line could be found on both sides of the board at several spots. You said that the Switch was working and stopped it after a case swapping, so I would try to focus first on the areas of the connectors (display, game card reader, cpu fan, backlight, speaker) to look for visible damage.
If you can t find something, I would give ice spray or a thermal cam a try. The place where it shorts out should be getting warm.
I have good news it was the lcd connectior after i have removed the switch function on the docking mode. Yet i need to replace them. I will replace it thank you for your help.
I never soldered a lcd connector back my self yet. But from my experience from changing usb-c ports I would recommend heating it up carefully from the backside with hot air. From the topside I was never able to get the solder liquid before melting the connectors (Beside the battery connector).
Here is a link to video how I would try it myself: _https://www.youtube.com/watch?v=snaq4r6DDeo
yeah it takes more precision to do it. After all, melting point for the connector material is lower than the solder. i would recommend to use the Aluminum foil to cover the the surrounding area as it can lower the heat.
I have replaced several connectors and and if you want to take a connector from another board i recommending that you add low melt solder on all pins and alot of premium flux.
Its really easy that way, without damage the connector
