Xiaomi Mi Air 13 - Missing Component identification

[servis_null]

Hi everyone,

I have Xiaomi Mi Air 13
Board number is: Marble 17805-1 448.0CE07.0011

Problem is burned and missing component that I need to identify.. mark on the board is QA702

QA701 looks same but I am not sure if it is (values), marking are AD XA 14

Also 5pin component (maybe LDO) with GAF marked on top gets hot.. for this GAF I manage to find that it should be AP2204K-ADJTRG1 or RP170N381B-TR-FE (maybe not, looks like GAF is general/factory marking)

Most important is missing QA702..

Looks like schematic or bv is impossible to find, so maybe anyone of you have same board somewhere under table, bed, garage

Can you guys help me out?

Thnx

I'm not 100% sure but the ADXA, is likely a: Alpha & Omega AO3413
