Hello!

Here must be two ceramic capacitors connected in parallel. The value of both is the same - most likely 10µF/25V, package 0805.
If you want to make 100% sure, remove the one that survived and measure its capacitance.

Please, post a clear picture with visible copper traces connected to these two components.
Also specify the markings on the removed QFN chip located next to these two components.

Try with the following values:
A= Capacitor 1µF/10V, package 0402
B= Resistor 17.8kΩ/1%, package 0201
C= Resistor 20kΩ/1%, package 0201

Okej, dziękuję za informację, mam nadal problem z laptopem, po podłączeniu do ładowarki nie zapala się dioda od podłączenia ładowarki i laptop nie reaguje na włącznik, rezystancja wydaje się że jest w porządku, zwarcie na płycie było na linii 5v, teraz już nie pokazuje zwarcia, uszkodził się układ ładowania ?
Ogólnie napięcie pokazuje się jakieś szczątkowe, nigdzie nie ma prawidłowego napięcia
