Witam,
Laptop trafił z ciemną matrycą podczas włączania (brak polaryzacji i podświetlenia).
Dysk nie startuje (led nie świeci).
Dioda "power" świeci przez 20 sekund, po czym gaśnie i ponownie się zapala.

Płytę pomierzyłem i wydaje się, że napięcia są ok.

Podejrzewam BIOS. Sczytałem zawartość, ale już nie mogłem wgrać zawartości ponownie do kości.
Sam wsad odczytany w HxD, a w miejscu klucza windowsa i numeru seryjnego są krzaki. Stąd podejrzenie, że BIOS jest uszkodzony

Kość to - XMC QU64AHIG.
Czy jest jakiś zamiennik tej kości, bo nie znalazłem oryginału w PL.

Jest gdzieś do do ściągnięcia również wsad?

Z góry dzięki za pomoc.

Hello!
Try with a Winbond W25Q64FWSSIQ, if it does not work, try with W25Q64FWSSIG.

This question belongs to the "ZAPYTANIA O DOKUMENTACJE/BIOS" department. Don't forget to specify the major ICs markings according to the rules.
