reason, BIOS will ask the password during systems POST or when system enters the BIOS
Setup menu. If it is necessary to bypass the password check, short the HW Gap to clear the
password by performing the following steps:
1. Remove power from the system.
2. Remove HDD, AC and Battery.
3. Disconnect the RTC Battery (Figure 5-3).
