Hard disk security

To protect the computer from unauthorized security attacks, refer to the following tips to enhance security:

• Set a power-on password as well as a hard disk password. For security, a longer password is

recommended.

• The hard disk drive built into your computer can be protected by UEFI BIOS. To provide reliable security,

use the security chip and a security program with the Trusted Platform Module (TPM) management
feature. See “Setting the security chip” on page 52.

• If a Disk Encryption storage drive is installed in your computer, ensure to protect the contents of your

computer from unauthorized access by use of drive encryption software, such as Microsoft Windows
BitLocker

Drive Encryption.

• Before you dispose of, sell, or hand over your computer, delete the data stored on it. For more

information, see “Deleting data from your storage drive” on page 54.

Using Windows BitLocker Drive Encryption

To help protect your computer against unauthorized access, use the drive encryption software, such as
Windows BitLocker Drive Encryption.

Windows BitLocker Drive Encryption (referred to as BitLocker) is an integral security feature of some editions
of the Windows operating system. It can help you protect the operating system and data stored on your
computer, even if your computer is lost or stolen. BitLocker can encrypt all user and system files, including
the swap and hibernation files.

BitLocker uses the TPM to provide enhanced protection for your data and to ensure early boot component
integrity. A compatible TPM is defined as a V2.0 TPM.

To check the BitLocker status, go to Control Panel, view Control Panel by Category, and click
