Thank you for your reply I understand your point, but this is the second time you have told me that the issue is not related to the BIOS. In a previous case with another laptop, you also said it wasn't the BIOS, but after checking, the problem was actually caused by the BIOS file
This laptop was powering on before I flashed the BIOS. After programming the BIOS, it no longer boots, and even restoring my original dump did not solve the issue. That's why I strongly believe the BIOS file or the programming process is involved.
Could you please review my original dump once again or compare it with a known-good BIOS for this motherboard? I would really appreciate your help. Thank you.
