Hello,
i need master bios password of hp probook 4520s.

PRODUCT:WS712EA#ACQ







Thanks,
 

You need to read BIOS EEPROM with SPEG programmer, after that content need to be washed, and in that state back to EEPROM.

You need to completely open device and remove main board outside, solder thin wires on BIOS EEPROM.......
