Hard disk security
To protect passwords from unauthorized security attacks, several of the latest technologies and algorithms
are integrated into UEFI BIOS and hardware design of ThinkPad notebook computers.
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” on page 50 and “Hard disk passwords” on page

. For security, a longer password is recommended.
2. If a Disk Encryption hard disk drive or a Disk Encryption solid-state drive is installed in your computer,
be sure to protect the contents of your computer memory from unauthorized access by use of drive
encryption software.
3. Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. Refer to
“Notice on deleting data from your hard disk drive or solid-state drive” on page 56
.
Note: The hard disk drive built into your computer can be protected by UEFI BIOS.

password for the internal storage device.
