passwords from unauthorized security attacks, several of the latest technologies and algorithms are
integrated into UEFI BIOS and hardware design of ThinkPad notebooks.
To maximize security, do the following:
1. Set a power-on password as well as a hard disk password for your internal solid state drive or hard
disk drive. Refer to the procedures in Power-on password and Hard disk passwords. For security,
a longer password is recommended.
2. To provide reliable security for UEFI BIOS, use the security chip and a security application with a Trusted
Platform Module management feature. Refer to Setting the security chip.
