Acer Sf314-41 power issue

[claws77]

i cannot desolder this with the equipment that i have. i tried on some scrap board to test my skill, it ended in a disaster.
i will try some more with the soldering iron.

It may be better to seek the help of a local phone repair tech. There should be some in your local malls.

On the posted pics, it appears that you have a SD card reader IC that is the square chip and these parts near the USB connector. Most likely these parts near the USB connector are a USB load switch (acts like a solid state fuse which should trip if an excessive current draw is active on the connector) and a TVS ESD array to suppress high speed transients from damaging the USB host controller. Either way, USB load switches and TVS ESD arrays do become defective and cause events like yours. We are removing these parts to see if they are shorted or not.
