Hello! Dell E7440 laptop based on VAUAO LA-9591P r1.0
I want to flash BIOS. I found two flash drives U1 and U2. According to the scheme I saw that U1 is W25Q64FVSSIQ (8mb), and U2 is W25Q32FVSSIQ (4mb)
And I have U1 is MX25L12805D (16mb), U2 is N25Q064A (8mb). Can it be like this from the factory?
How do I flash the bios now with a dump from 8 and 4mb to 16 and 8mb?

Schematic & Boardview for MSI B250 Gaming M3
MS-7A62 rev 1.0...

Hello. MSI B250 Gaming M3 board, short-circuit on the power supply. Found a problematic mosfet VQ1
(N-PK616BA_PDFN8-HF) soldered it out - short circuit is gone. I replaced VQ1 + VQ5 (N-PK632BA_PDFN8-HF). VQ1 was replaced with PK618. After starting attempt VQ1 is lit again. What can be the problem? In the driver?
