I unsoldered it to take the photo below, and we put new tin on it and assembled it. And it does the same.
The chip is part of the current input circuit of the single USB-C port, I have also changed the previous mosfet (EMB20P03), and nothing....

Help to identify component HUAWEI MATEBOOK 15- USB-C POWER - Looping from 5V to 0.9V - IC U20 90º celsius HOT!!
First of all, thank you all for the help you provide in this forum.
HUAWEI Matebook D15 Laptop - Mod: BOB-WAH9 - Motherboard: DAH98MMB8D0 REV D
Can anyone help me locate the manufacturer of this IC? and tell me if the IC U20 is really the problem.
When looking at the board with the thermal camera, the integrated U20 is set to 90-95 degrees Celsius and the USB-C tester that I have between the charger and the laptop, oscillates between 5V and when it reaches 95º, it drops to 0.9V... .and so on in loop mode.
There are no apparent shorts in the...3 Photos

Re: need bios dv7 i7cpu
Hi gcomputer,
you fix the problem? I have 2 computers with the same failure. dv6 and dv7. Power on and power off in 2 seconds (black screen)
I saw in another thread that failure can be the switch, (component c1), I haven't the laptop here now, I'll look if my model have that component tomorrow.
