Lenovo Legion 5 MB L82B5 schematics

[volinakis]

Hi, help me please to identify IC marked UX2 in photo.
There was no 5V and 3,3V stand by, after I remove it I have 5V, 3,3V and 1,2V for RAM, also 0,8V for CPU, there is no Ualim for GPU. Power led is blinking continuosly.
Thank you.

Exact IC number is hard to tell since the component is burned. But based on the connections, it does look like a load switch.

What is the motherboard part no ?

It could be a GMT5016 - https://cdn.badcaps-static.com/pdfs/...a101791404.pdf

Try to get a better image, or at least part of the marking on it

Thanks for info, based on your infos I replaced burned IC with an APL3533 - basically is the same as GMT5016. Now Ihave Vin1-3,3V and Vout1- 0,58V and Vin2-5V and Vout2 5V. I think is an overload on Vout 1, I'll keep digging.
