Please i need help with a conpaq nx6310 mb:6050a2035001 is an old model,was not turning on cause 19V didn't pass the ac MOSFET, the issue was with lm393 circuit detecting Vac charger,now it turns on, HP logo and ask for a system password to boot or to enter setup, downloaded a bios DUMP i don't believe it has any password and flashed it, and again same problem.Something interesting is when i solder the ROM the first time i turn it on it fisplays updating keyboard controller, a question,the password can be stored in the SUPER/IO???It's SMSC KBC1021, it's the only explanation i have for what's happening,loosing my mind with this l,any ideas???
