x7400pc r4.0 bios
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...

I repairing notebooks for computer shops, i say them to "i disable onboard ram" and they ask their customers then they say ok, i do not want to risk it because i do not like when devices return later with same failure and reflowing not good option. I find some Russian video and i try that but not work, they remove resistor array extra than 4 id resistor, i think they manipulate mem_alert but not work for me, i try because someone in their comments saying work. Sorry for my poor Englisk., Can you at least remove spd from my bios?...Leave a comment:
