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 42 and "Hard disk passwords" on page
42. 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 accesses 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 46.
Note: The hard disk drive built into your computer can be protected by UEFI BIOS.
Disk Encryption hard disk drive and Encryption solid-state drive
Some models contain the Disk Encryption hard disk drive or Encryption solid-state drive. This feature
helps to protect your computer against security attacks on media, NAND flash or device controllers by use
of a hardware encryption chip. For the efficient use of the encryption feature, be sure to set a hard disk
password for the internal storage device.

Notice on deleting data from your hard disk drive or solid-state drive

As computers spread into every corner of life, they process more and more information. The data on your
computer, some of which might be sensitive, is stored on a hard disk drive or solid-state drive. Before you
dispose of, sell, or hand over your computer, be sure to delete data stored on it.
Handing your computer over to someone else without deleting the loaded software, such as operating
systems and program software, might even violate license agreements. You are advised to check the
terms and conditions of those license agreements.
There are methods that seem to delete the data:
• Move the data to the recycle bin, and then empty the Recycle Bin.
• Delete the data.
• Format your hard disk drive or solid-state drive, using the software for initializing it.
• Use the recovery program provided by Lenovo to bring the hard disk drive or solid-state drive back to
the factory default settings.
These operations, however, only change the file allocation of the data; they do not delete the data itself. In
other words, the data retrieval processing is disabled under an operating system such as Windows. The
