data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of
special software for data recovery. There is a risk that people of bad faith might read and misuse the critical
data on storage drives for unexpected purposes.
To prevent leakage of data, it is important that you delete all the data from the hard disk drive or hybrid drive
when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the
hard disk drive or hybrid drive with a hammer, or magnetically by means of strong magnetic power, thus
making the data unreadable. But it is recommended that you use the software (payware) or service (pay
service) developed for that purpose. The process might take several hours.
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive or
hybrid drive, Lenovo provides the Secure Data Disposal™ tool. Go to http://www.lenovo.com/support
to download the tool.
If a Disk Encryption hard disk drive, Encryption solid-state drive, or Encryption hybrid drive is supported and
installed in your computer, you can logically dispose of all the data on the drive in a short time by erasing the
cryptographic key. The data encrypted with the old key is not physically erased but remains on the drive;
however, it cannot be decrypted without the old key. This feature is also available with the Drive Erase Utility
for Resetting the Cryptographic Key and Erasing the Solid State Drive tool.
Using firewalls
If your system is preinstalled with a firewall program, it protects against computer Internet security threats,
unauthorized access, intrusions, and Internet attacks. It also protects your privacy.
For more information about how to use the firewall program, refer to the help information system that
comes with the program.
Protecting data against viruses
Your computer is preinstalled with an antivirus program so you can detect and eliminate viruses. The
antivirus program is designed to help you detect and eliminate viruses.
Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After
30 days, you must renew the license to continue receiving the antivirus software updates.
For more information about how to use your antivirus software, refer to the help information system of
your antivirus software.
