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.
Setting the security chip
Strict security requirements are imposed on network client computers that transfer confidential information
electronically. Depending on the options you ordered, your computer might have an embedded security
chip, a cryptographic microprocessor. With the security chip, you can do the following:
• Protect your data and system
• Strengthen access controls
• Secure communications

follows:
