x7400pc r4.0 bios

[relax79]

Hello friends, sorry for my poor English.this notebook power led always on when i plug in dc adapter and there is no charge led or charge activity. Main vcc show 8.4v and what i see this design uses low supply rail equal to battery like macbooks. I try to download from support and it says latest one 303 but when i unpack with Uniextract then i learn it is crypted then i find ami guard tool then i read in hex editor it says 309 somehow but no problem because mine also same, i copy paste new bios via hex editor and programmed via programmer but nothing cahange. Rest is i do not know how to repair or clean the me or put dmi from old one. There are no short or failure on the board and it looks bios because i found this when i search on google

i do not manage to add link as i see and i copy paste here "https://***********/threads/asus-x7400pc.45406/post-476380"
user says same fault like me and say work with other bios.

Asus vivobook pro 14 oled
Model : k3400p (when search on support site via serial, it find x3400phb)
Motherboard : x7400pc r4.0
Serial : n3n0cx12k126106
