AAL10 LA-B843P

The laptop does not display an image.
3.3V present on BIOS pin 8 ⇒ VCC_SPI line and standby power are functional
Fan runs briefly
No image (no POST video)
No RAM memory → IDENTICAL behavior ⇒ system does not reach memory initialization stage
Diagnostic LED 3 blinks (short – long – short) ⇒ indicates firmware error / BIOS initialization failure
! at first startup changes occur in the chip content, dump read later ≠ original dump written

All the bios dumps I tried didn't work, please help
